  • a bumper reinforcement is disposed at a front section of a vehicle for collision safety. Since front surfaces of the condenser and the sub-radiator are covered by the bumper reinforcement, cooling airflow volume reduces and thereby heat radiation performance reduces. In addition, a size of the sub-radiator becomes large due to the built-in water-cooled condenser in the side tank of the sub-radiator, so that designing of layout is restricted in a case of a vehicle whose front section has a relatively narrow space.
  • a pipe(s) is protruded forward from the water-cooled condenser, so that arrangement of the bumper reinforcement in a front section of a vehicle becomes difficult and refrigerant leakage from the refrigerant pipe(s) protruded forward is apprehended in a slight collision to a front section of a vehicle.
  • An object of the present invention is to provide a water-cooled condenser that can improve heat radiation performance and can be adapted to arrangement of a bumper reinforcement at a front section of a vehicle.
  • An aspect of the present invention provides a water-cooled condenser that exchanges heat between refrigerant of an air conditioner for a vehicle and coolant, and then send the refrigerant out to a air-cooled condenser through a refrigerant outlet port, wherein the refrigerant outlet port is connected with the air-cooled condenser at a position that doesn't overlap a bumper reinforcement arranged in front of the air-cooled condenser at a front section of the vehicle when viewed along an airflow direction toward the air-cooled condenser.
  • the refrigerant outlet port of the water-cooled condenser is connected with the air-cooled condenser at the position that doesn't overlap the bumper reinforcement, the refrigerant that flows into the air-cooled condenser through the refrigerant outlet port flows much at the position that doesn't overlap the bumper reinforcement and thereby superior heat radiation performance can be brought by a sufficient cooling airflow volume. Therefore, total heat radiation performance achieved by the air-cooled condenser and the water-cooled condenser can be improved and the water-cooled condenser can be adapted to arrangement of the bumper reinforcement at the front section of the vehicle.
  • the refrigerant outlet port is disposed above or beneath the bumper reinforcement. Namely, the refrigerant outlet port is shifted vertically so as not to overlap the bumper reinforcement, and a position with a small refrigerant flow rate right next to the above-mentioned position where the refrigerant flows much overlaps the bumper reinforcement. As a result, affection by reduction of a cooling airflow volume can be restricted to a minimum to improve total heat radiation performance.
  • a sub-radiator for exchanging heat between the coolant and outside air is provided above or under the air-cooled condenser, and the bumper reinforcement is disposed so as to overlap a portion of the air-cooled condenser and a portion of the sub-radiator. According to this, affection by reduction of a cooling airflow volume can be dispensed to the air-cooled condenser and the sub-radiator, and a refrigerant pipe between the water-cooled condenser and the air-cooled condenser and a coolant pipe between the water-cooled condenser and the sub-radiator can be shortened.
  • a coolant inlet port to the sub-radiator is disposed at a position that doesn't overlap the bumper reinforcement when viewed along the airflow direction. According to this, the coolant that flows into the sub-radiator through the coolant inlet port flows much at the position that doesn't overlap the bumper reinforcement and thereby superior heat radiation performance can be brought by a sufficient cooling airflow volume. As a result, temperature of the coolant used for the water-cooled condenser is reduced to improve total heat radiation performance achieved by the air-cooled condenser and the water-cooled condenser.
  • the water-cooled condenser is disposed on one side of the sub-radiator and the air-cooled condenser, and a liquid tank for accumulating part of the refrigerant is disposed on another side of the air-cooled condenser. According to this, the water-cooled condenser or the liquid tank can be prevented from contacting with the bumper reinforcement in a slight collision of a vehicle, and thereby refrigerant leakage can be prevented.

  • Each inside of the first tank 31 and the second tank 32 is also partitioned into upper and lower sections in accordance with the condensing section 30 a and the subcooling section 30 b.
  • the refrigerant flows into the air-cooled condenser 3 from an upper portion of the first tank 31 .
  • the refrigerant flows through the condensing section 30 a rightward in FIG. 1 , and then flows downward in the upper section of the second tank 32 , and flows into the lower section of the second tank 32 via a liquid tank 33 connected with the second tank 32 .
  • the refrigerant flows into the subcooling section 30 b from the lower section of the second tank 32 .
  • the refrigerant flows through the subcooling section 30 b rightward in FIG. 1 , and then flows out from the air-cooled condenser 3 via the lower section of the first tank 31 .
  • the liquid tank 33 may be a gas-liquid separator for separating refrigerant liquid and refrigerant gas, or a modulator provided in a subcooling-type condenser.
  • the water-cooled condenser 4 in the present embodiment is connected with the sub-radiator 2 and the air-cooled condenser 3 .
  • a flow passage for the coolant and a flow passage for the refrigerant are separated with each other in the inside of the water-cooled condenser 4 and the coolant and the refrigerant are not mingled, but heat is exchanged between the coolant and the refrigerant (the refrigerant is cooled by the coolant).
  • the coolant that flows out from the sub-radiator 2 flows into an upper portion of the water-cooled condenser 4 through a flexible coolant flow-in pipe 5 disposed at an upper end of the water-cooled condenser 4 .

  • the water-cooled condenser 4 includes a casing 40 extended vertically.
  • a heat exchanging portion (refrigerant flow passage) where heat is exchanged between the refrigerant and the coolant and a tank (coolant flow passage) formed between the heat exchanging portion and the casing 40 for accumulating the coolant are provided within the casing 40 .
  • the water-cooled condenser 4 is disposed independently beside the sub-radiator 2 and the air-cooled condenser 3 (lateral to the sub-radiator 2 and the air-cooled condenser 3 in parallel to the bumper reinforcement 9 ).
  • the lower portion of the water-cooled condenser 4 is attached to a sidewall of the first tank 31 of the air-cooled condenser 3 via the intermediate connecting member 8 , and fixed with the first tank 31 of the air-cooled condenser 3 by a bracket 42 .
  • the upper portion of the water-cooled condenser 4 is fixed with the sub-radiator 2 via a bracket 41 .
  • the upper end of the water-cooled condenser 4 is connected with a sidewall 20 of the sub-radiator 2 via the flexible coolant flow-in pipe 5 .
  • the intermediate connecting member 8 (refrigerant outlet port 8 a ) is connected with the air-cooled condenser 3 slightly beneath (the lower edge of) the bumper reinforcement 9 , i.e. at a position that doesn't overlap the bumper reinforcement 9 (a position shifted vertically so as not to overlap when viewed from a front of the vehicle: a position that doesn't overlap when viewed along a direction of airflow toward the air-cooled condenser 3 ). Since the refrigerant flows into the air-cooled condenser 3 through the refrigerant outlet port 8 a, the refrigerant flows much in the tube(s) at a level of the above-explained connection position.
  • connection position is located slightly beneath the bumper reinforcement 9 , a cooling airflow volume is large and thereby heat radiation performance doesn't reduce.
