Inlet/outlet connector for heat exchanger

A heat-exchanging plate (), and plate heat exchanger () using same. The heat-exchanging plate () comprises concave locations () and/or convex locations (), and is provided with multiple heat-exchanging units thereon. At least one inlet and/or at least one outlet of at least one of the heat-exchanging units is controllable.

Heat-exchanging plate, and plate heat exchanger using same

A heat-exchanging plate (), and plate heat exchanger () using same. The heat-exchanging plate () comprises concave locations () and/or convex locations (). In at least one partial region of the heat-exchanging plate (), a transitional curved surface between at least two adjacent concave location () and/or convex location () is configured to be controllable.

Provided are a reinforcer () used for a plate heat exchanger () and a plate heat exchanger (), the reinforcer () being used to reinforce an area around an opening () of at least one heat exchange plate (). The plate heat exchanger () comprises multiple heat exchange plates (); a heat exchange space formed between adjacent heat exchange plates () of the multiple heat exchange plates (); a heat exchange channel () formed between the heat exchange plates (), wherein the heat exchange channel () is used for a heat exchange medium to flow into or out of the plate heat exchanger (), and is constituted by openings () in the multiple heat exchange plates (); and a reinforcer (), used to reinforce an area around an opening () in at least one heat exchange plate (). The plate heat exchanger () can alleviate or prevent deformation or cracking of a backing plate () and a heat exchange plate () of the plate heat exchanger (), especially the two heat exchange plates () adjacent to the backing plate (), in the area around the heat exchange channel ().

Reinforcer used for plate heat exchanger and plate heat exchanger

A heat exchange tube () for a heat exchanger, heat exchanger and assembly method thereof. The heat exchange tube () is a combined heat exchange tube having a space () at its center, and the space () is configured to accommodate an insertion member (), such that the combined heat exchange tube is expanded in and joined with a corresponding fin hole () in the heat exchanger. A heat exchange tube that is minute or has a small inner diameter can thus be expanded in a heat exchanger fin without employing a brazing process.

Heat exchange tube for heat exchanger, heat exchanger and assembly method thereof

Disclosed in the present invention is a refrigeration system, comprising: an evaporator and a condenser connected by a pipeline, wherein: at least one of the evaporator and the condenser comprises a heat exchange tube, the heat exchange tube comprising a first channel and a second channel, and the first channel and the second channel of the heat exchange tube forming different flow paths of the refrigeration system.

Refrigeration system

A heat exchange plate for a plate-type heat exchanger and a plate-type heat exchanger provided with said heat exchange plate. The heat exchange plate includes an opening used to form an end opening, a plurality of protrusions arranged around at least a portion of the opening along a circular line along the opening, the plurality of protrusions protruding towards one side of a plate plane; transition portions arranged between at least two neighbouring protrusions, the transition portions being located on one side of the plate plane, and being a preset distance from the plate plane. The distance from the tops of the protrusions to the plate plane is greater than the distance from the lowest points of the transition portions to the plate plane.

Heat exchange plate for plate-type heat exchanger and plate-type heat exchanger provided with said heat exchange plate

A heat exchanging board () and a board-type heat exchanger provided with the heat exchanging board (). The heat exchanging board () comprises a board main body (). Multiple recessed portions () and multiple raised portions () are disposed on the surface of the board main body (). The multiple recessed portions () and the multiple raised portions () are disposed in a staggered manner along a first direction (S) and are disposed in a staggered manner along a second direction (S) perpendicular to the first direction (S). Top portions of the multiple raised portions () are provided slender forms along the first direction (S). The heat exchanging board () and the board-type heat exchanger provided with the heat exchanging board () can ensure good strength of the heat exchanger in the case of ensuring the heat exchanging efficiency, and can reduce manufacturing cost of the heat exchanging board ().
