Abstract: In a heat exchanger with a receiver tank, a coupling member and an adapter member constitute a connecting member that connects the receiver tank and the heat exchanger, where the connecting member has header connecting portions respectively connected with a concentrating part and a supercooling part of one of headers and the adapter member is connected with the connecting member and the receiver tank and is detachably attached to the receiver tank. The coupling member is assembled with a first divided member and a second divided member, where the first divided member is formed with header connecting portions to be connected with the second divided member.

Abstract: A fan shroud structure includes a heat exchanger and a fan shroud. The heat exchanger has an upper tank and a lower tank, and the upper tank and the lower tank sandwich a core part therebetween. The fan shroud is attached to the heat exchanger, and the fan shroud has a wall portion and a flange portion projecting toward the heat exchanger from an outer circumference of the wall portion, and the flange portion including a lower flange portion. The lower flange portion is provided with a water discharge outlet for discharging water in the fan shroud outside of the fan shroud through the water discharge outlet.

Abstract: A pipe connecting structure has a connector block fixed to a header tank of a heat exchanger and formed with a through-hole and a large diameter hole, a header side pipe having a base end portion connected with the header tank and a diameter expansion portion formed at its top portion and inserted into the large diameter hole of the connector block, and a vehicle side pipe having an end portion connected with a vehicle side device and a top portion inserted into the diameter expansion portion of the header side pipe through the through hole. The diameter expansion portion of the header pipe is brazed to the connector block, and the top portion of the vehicle side pipe is fixed to the connector block with a seal member between the connector block and the top portion of the vehicle side pipe.
