A liquid-cooled heat dissipation device is disclosed, comprising a main body, a centrifugal pump, an inlet pipe, an outlet pipe, a centrifugal fan and a motor. The main body comprises a shaft hole, liquid flow channels and airflow channels. The centrifugal pump guides a cooling liquid through the inlet pipe, main body and outlet pipe. The centrifugal fan guides air into the main body axially from the shaft hole. After passing through the centrifugal fan, the air forms centrifugal airflows and leaves the body radially through the airflow channels. With an extended flow path of the cooling liquid and the radial flow of the centrifugal airflow provided by the present invention, the temperature of the cooling liquid may be quickly reduced and the cooling effect may be improved. Thus, the structure is compact, small, light-weight, easy-to-assemble.

A cooling fan module is provided. The cooling fan module may include a frame, a fan assembly, a number of guide vanes, and a cylindrical deflector. The frame may include a sidewall that defines an opening and an outer periphery. The fan assembly may be disposed within the opening and include fan blades extending from a hub and terminating at a fan ring. The fan ring may have a curved profile. The number of guide vanes may be disposed radially around the opening. The cylindrical deflector may extend axially from the sidewall and radially surround the number of guide vanes. The cylindrical deflector may be disposed radially between the number of guide vanes and the outer periphery.

The invention relates to the technical field of water-cooling radiators, in particular to an integrated radiator provided with a water chamber, a control panel, and a water pump. The control panel is provided with a port set electrically connected with the control panel. According to the integrated radiator, the water pump assembly is integrated on the cooler through reasonable design, so that the weight of a block is effectively reduced. Meanwhile, wires of a fan and the block are connected to the port set on the control panel to be prevented from being suspended in a case, so that the internal attractiveness of the case is improved; besides, more cooling liquid is contained, so that the service life of the integrated water-cooling radiator is prolonged.

A heat exchanger replacement mounting pin and drill jig for replacing a broken mounting pin of a heat exchanger, which includes the following: a replacement mounting pin portion; a bore defined by the replacement mounting pin portion for guiding a drill to a mounting site of the heat exchanger; and a nut alignment portion extending from the replacement mounting pin portion.

A tank assembly includes a heat exchanger tank and at least one side plate. Each heat exchanger tank includes a pair of foot portions and a pair of top portions. The foot portions are crimped to a corresponding header of a heat exchanger core. The top portions are configured with first engagement elements. The at least one side plate is disposed on at least one side of the heat exchanger core and is configured with second engagement elements. The second engagement elements engage with the corresponding first engagement elements to urge the heat exchanger tank towards the header.

A heat exchanger includes a core and a header tank. The header tank includes a partition, a first inlet pipe, and a second inlet pipe. The partition divides an inside passage of the header tank into a first tank and a second tank. The first inlet pipe introduces a first fluid into the first tank. The second inlet pipe introduces a second fluid into the second tank. The first inlet pipe is inclined at a predetermined angle except a right angle relative to an outer surface of the header tank such that a flow direction of the first fluid flowing from the first inlet pipe to the first tank includes a component in a predetermined direction from a first end of the first tank provided with the partition to a second end of the first tank opposite to the first end.

A heat exchanger for a vehicle includes a heat exchanger core. The heat exchanger core is configured to exchange heat between fluids. The heat exchanger further includes a header. The header is in fluid communication with the heat exchanger. A bracket is coupled to the header by a cold forming process.

A liquid receiver of a condenser has a liquid receiver main body and a plug removably fitted thereinto. The liquid receiver main body has a refrigerant inflow hole into which refrigerant flows from a condensation section and a refrigerant outflow hole from which refrigerant flows into a supercooling section. The liquid receiver has a first space formed above the upper end of the plug and communicating with the refrigerant inflow hole and a second space formed below the upper end of the plug and communicating with the refrigerant outflow hole. The plug has a flow passage which is open to the first space and the second space at opposite ends. The first-space-side opening of the flow passage is located below the refrigerant inflow hole. The flow passage has a throttle portion whose cross-sectional area is smaller than a hole area of the refrigerant inflow hole.

A cooling fan module is provided. The cooling fan module may include a frame, a fan assembly, a number of guide vanes, and a cylindrical deflector. The frame may include a sidewall that defines an opening and an outer periphery. The fan assembly may be disposed within the opening and include fan blades extending from a hub and terminating at a fan ring. The fan ring may have a curved profile. The number of guide vanes may be disposed radially around the opening. The cylindrical deflector may extend axially from the sidewall and radially surround the number of guide vanes. The cylindrical deflector may be disposed radially between the number of guide vanes and the outer periphery.
