Abstract: A receiver has a good usage for receiving coolant in a refrigerant circuit. The receiver can improve the fixing and the connecting operation when the receiver is connected with the refrigerant circuit provided in an automotive engine room. The receiver is comprised of a receiver housing having a flat upper surface and a couple of block joints having a flat lower surface. The block joints are furnished on the upper surface of the receiver housing by screwing. The block joints have connecting halls an inlet and an outlet pipes are jointed therein. At least one of the connecting halls are formed vertically so that at least one of the inlet and the outlet pipes elongates upwardly. Therefore, the inlet or the outlet pipe has advantage to be connected easily and effectively.

Abstract: A cooling system control apparatus includes an electronic control unit to individually control the operation of an engine water pump, a radiator fan motor and an electromagnetic valve for bypassing the cooling water passage to the radiator, on the basis of a cooling water temperature. When the cooling water temperature is below about 85.degree. C., the water pump is stopped to raise the cooling water temperature rapidly, and when the cooling water temperature is above about 85.degree. C., the water pump is operated and the electromagnetic valve is operated to bypass the cooling water passage to the radiator, and when the cooling water temperature is above about 90.degree. C., the fan motor is operated and also the electromagnetic valve is operated to allow the cooling water to pass through the radiator.
