A heat exchanger mounting structure is provided with a bracket, a load supporting section, a fitting member, and a contact section. The bracket is provided to one of a first heat exchanger and a second heat exchanger. The load supporting section is provided to the other heat exchanger to which the bracket is not provided, and supports a load transmitted from the one of the first heat exchanger and the second heat exchanger. The fitting member is provided to the one of the first heat exchanger and the second heat exchanger, to which the bracket is provided, and is fitted over the load supporting section. The contact section is in contact with at least a part of the upper portion of the bracket.

An air cleaner unit for a vehicle includes an air cleaner element and an air cleaner housing to be arranged generally above ring portions of a fan shroud. The air cleaner element is disposed in the air cleaner housing such that a predetermined space is provided between a lower surface of the air cleaner element and an inner surface of a bottom wall of the air cleaner housing. The bottom wall of the air cleaner housing includes at least two arcuate portions to correspond to the ring portions of the fan shroud and a projecting portion between the arcuate portions. The projecting portion projects downwardly and is configured to increase the volume of the predetermined space.

A fan has a plurality of blades extending in a radial direction with respect to a rotation axis and a ring portion disposed on radial outside edges of the blades. Further, the fan has a first connecting wall and a second connecting wall. The first connecting wall extending from the ring portion to a portion of the radial outside edge of each blade, the portion protruding from the ring portion toward an upstream position with respect to an air flow direction. The second connecting wall has a generally triangular shape. The second connecting wall continuously extends from the first connecting wall and connects to the ring portion on a leading side of the first connecting wall with respect to a rotation direction of the blade. The fan is for example housed in a shroud, thereby to construct a blower unit.

The discharge water means () is provided within an area equal to or more than an area of the shroud extending to 20 degree points in both directions from a center that is a lowest portion of the ring portion (). Due to this, if water drops adhered to the surface of the blade wheel () and the shroud () are collected at the lower side thereof due to gravity, it is possible to readily discharge the water. As a result, as it is possible to prevent the water drops from being stored in a clearance between the blade wheel () and the shroud (), even when the temperature of the atmosphere is low in a winter season or the like, it is possible to prevent a freezing lock phenomenon from occurring.

Electric fan for vehicle use

An electric fan system has a first electric blowerwhich utilizes a brushless motor, and a second electric blower, which utilizes a brushed motor, for distributing the cooling air to the radiator and the condenser. The system has an electronic engine control unit which activates only the first electric blower when it determines that the cooling water temperature is less than Tand activates both the first and second electric blowers when it determines that the cooling water temperature is Tor higher. The water temperature is based on a detection output from a cooling water temperature sensor. Thus, since the electric blower is not activated unless the cooling water temperature becomes Tor higher, use of the brushed motor is limited and its life is increased.

Front edges of blades are so constituted as to be deviated toward the upstream side in the air stream beyond an axial end surface , as viewed from a direction at right angles to the axial direction of a boss and the blades on the root side thereof are continuous to the axial end surface through smoothly curved surfaces This enables the air to flow from the side of the axial end surface toward the root side of the blades . Due to the air flowing from the side of the axial end surface to the root side of the blades therefore, the resistance decreases between the air and the surfaces of the blades on the root side, making it possible to suppress the occurrence of stalling on the root side of the blades The air on the front side of the boss is effectively guided toward the outer direction (toward the blades ), preventing a drop in the flow rate and in the fan efficiency of a blower

The present invention provides a seal portion mounted on an inner wall of a cap. When the cap is removed from the main body of the container, the seal is positioned below a position where a first screw thread is screwed to a second screw thread. The first screw thread is formed on inside or outside of an outer cylindrical wall of the main body of the container. Whereas, the second screw portion is formed on the outer circumference or the inner circumference of the outer wall portion of the cap.
