A cold storage heat exchanger includes refrigerant tubes having therein refrigerant passages and arranged to provide a clearance therebetween. A cold storage container is bonded to a refrigerant tube and defines therein a compartment receiving a cold storage material. The cold storage container has protrusion portions protruding outward and being in contact with the refrigerant tube.

Cold-storage heat exchanger

When a refrigerant flow-path switch performs switching to a first refrigerant flow path, an interior condenser heating air blown into an interior as a first temperature-adjustment subject and an auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger heats air blown to a battery as a second temperature-adjustment subject. In contrast, when the refrigerant flow-path switch performs switching to a second refrigerant flow path, an interior evaporator cooling air blown into the interior and the auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger cools the air blown to the battery. With this arrangement, one common auxiliary heat exchanger can cool or heat the air for the battery, thereby leading to reduction in size of an entire refrigeration cycle device.

Refrigeration cycle device

A cold storage heat exchanger includes multiple refrigerant tubes arranged to provide a clearance therebetween, multiple cold storage containers each of which is interposed between adjacent refrigerant tubes, bonded to the adjacent refrigerant tubes and defining a compartment receiving a cold storage material. A surface of each cold storage container has multiple protrusion portions, and each protrusion portion protrudes outward and is in contact with the adjacent refrigerant tubes. The multiple protrusion portions are arranged in a zigzag manner or extend continuously in an air flow direction.

A refrigeration cycle device includes an air heat exchanger that heats air to be blown into an interior of a vehicle compartment using refrigerant discharged from a compressor, a high-stage side expansion valve decompressing the refrigerant flowing out of the air heat exchanger, and a battery heat exchanger that heats air to be blown to a battery using the refrigerant decompressed by the high-stage side expansion valve. In an air heating-warming up mode of heating the air for the interior and the air for the battery, a refrigerant discharge capacity of the compressor is controlled such that an air temperature for the interior approaches a target air temperature, and an opening degree of the high-stage side expansion valve is controlled such that a battery temperature becomes within a predetermined reference temperature range. A selector switch allows a passenger to select which operation of air conditioning or warming-up is prioritized.

A heat pump cycle includes a refrigerant circuit and a coolant circuit. A first heat exchanger and a second heat exchanger are disposed between the refrigerant circuit and the coolant circuit. The first heat exchanger includes an exterior heat exchanger that functions as an evaporator in a heating operation, and a radiator for radiating heat of a coolant. The second heat exchanger transmits a heat of high-pressure refrigerant to the coolant in the heating operation. A temperature of refrigerant within the second heat exchanger is higher than a temperature of refrigerant within the first heat exchanger. The heat obtained from the second heat exchanger is supplied to the first heat exchanger through the coolant. Further, the heat obtained from the second heat exchanger is stored in the coolant. In defrosting operation, the coolant that has stored the heat therein is supplied to the first heat exchanger.

Temperature regulation device

An object of the invention is to provide an effective cooling-energy storing performance and a stable cooling-energy radiating performance and to realize a high productivity. An evaporator has a plurality of refrigerant tubes arranged at almost equal intervals to form therebetween accommodating spaces. A plurality of cooling-storage containers are arranged in some of the accommodating spaces and fins are arranged in the remaining accommodating spaces. A cooling-storage unit is formed by one cooling-storage container and two refrigerant tubes arranged at both sides of the cooling-storage container. Each of the cooling-storage container has projections extending from one wall portion to the other wall portion to form heat exchange portions. The cooling-storage container is connected to the refrigerant tubes by soldering material.

Cool-storage type heat exchanger

A vehicular thermo-control device adjusts a temperature of a battery. The device has a primary system through which cooling water circulates, and a secondary system through which a refrigerant circulates. The primary system has a heat exchanger which performs heat exchange between the battery and the cooling water, and a heat exchanger which performs heat exchange between the cooling water and an ambient air. The secondary system is a refrigerating cycle. Both heat exchangers on a high temperature side and a low temperature side of the refrigerating cycle are thermally coupled with the primary system. Only one heat exchanger provides heat exchange with the ambient air. The pump of the primary system can switch circulating direction of the cooling water. A controller controls devices to perform cooling and heating operation.

Vehicular thermo-control device

A cold storage heat exchanger includes multiple refrigerant tubes, a cold storage container, an inner fin, a cooling air passage and an air-side fin. The inner fin is arranged inside of the cold storage container. The cooling air passage, in which air flows to cool a space, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container. The air-side fin is arranged in the cooling air passage and thermally connected to the refrigerant tube. The cold storage container includes multiple recess portions bonded to the inner fin, and multiple protrusion portions located on an outer side of the recess portions. The protrusion portions of the cold storage container are bonded to an outer surface of the refrigerant tube.

An outer surface of a cold-storage container (or a refrigerant tube) is provided with a plurality of protrusion portions or recess portions. A cooling air passage, in which air flows to cool a space to be cooled in a cold storage time and in a cold release time of the cold storage material, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container bonded to the refrigerant tube. The refrigerant tubes and the cold storage container form therebetween a cold-storage side air passage by the protrusion portions or the recess portions, such that air flows in the cold-storage side air passage separated from the cooling air passage. For example, the cold-storage side air passage is provided with a slanting space that causes condensed water or ice generated in the cold storage time to be drained along the cold-storage side air passage.

A cold storage heat exchanger includes multiple refrigerant tubes, a cold storage container that is bonded to the refrigerant tube and defines a compartment receiving a cold storage material, and an inner fin arranged inside of the cold storage container. The cold storage container has a portion that stops and fixes the inner fin, and the cold storage container has a space where air is sealed. The space of the cold storage container is located at an upper side of the member that stops and fixes the inner fin. Accordingly, a stress applied to the cold storage container in the expansion of the cold storage material can be reduced.

A cold storage heat exchanger includes multiple refrigerant tubes having therein refrigerant passages. The refrigerant tubes are arranged to provide a clearance therebetween. The cold storage heat exchanger further includes a cold storage container that is brazed with the refrigerant tube and defines a compartment receiving a cold storage material. The cold storage container has an open-hole portion at a brazed part with the refrigerant tube. Accordingly, efficiency of heat exchange by the cold storage heat exchanger can be improved.
