Definitions

  • the present invention relates to a heat exchanger for cooling a fuel cell of a fuel-cell powered vehicle.
  • cooling water can be used as a coolant.
  • a radiator heat exchanger
  • a coolant circulation passage through which a coolant is circulated in the fuel cell.
  • an electric insulation liquid material is used as the coolant.
  • the electric insulation liquid material is fluorinert (Sumitomo 3 M make) of a fluoride inet liquid or an insulating oil.
  • an insulating material is interposed between the fuel cell and the coolant circulation passage, or the coolant circulation passage is formed from an insulating material, so that the radiator is electrically insulated from the fuel cell.
  • the electrical insulating liquid such as the fluorinert has a low electrical conductivity as compared with a general coolant such as water and ethylene glycol. Therefore, it is difficult to sufficiently improve cooling performance in the radiator. Further, manufacturing cost of the cooling system of the fuel cell is increased because the electrical insulating liquid such as the fluorinert is expensive as compared with the general coolant.
  • Each component of the radiator may be formed by an insulation material in order to provide the insulating performance in the radiator while the general coolant is used.
  • heat conductivity of the radiator is greatly deteriorated, and it is difficult to obtain a necessary cooling capacity in the radiator.
  • a heat exchanger includes a plurality of tubes through which a coolant from a fuel cell flows to perform heat exchange, a plurality of fins arranged between adjacent the tubes and outermost sides of the tubes in a lamination direction of the tubes to be bonded to the tubes, a core plate connected to one longitudinal end portion of each tube, and a tank member made of resin.
  • the tubes are made of a first insulating material, the tank member is attached to the core plate at a side opposite to the tubes with respect to the core plate, and the tank member and the core plate are attached to form a tank space communicating with the tubes.
  • the tubes have a plurality of metal parts separated from each other on outer surfaces of the tubes, and the fins and the core plate are bonded by brazing to the outer surfaces of the tubes at the metal parts. Because the metal parts are separated from each other on the outer surfaces of the tubes, it is possible to electrically insulate the fins and tube parts connected to the fins in the heat exchanger, even when a water-included liquid is used as the coolant. In addition, heat exchanging performance can be improved by the fins made of a metal material.
  • a coating portion is coated by a second insulating material on one surface of the core plate opposite to the tank space.
  • the core plate has an exposed portion exposed to outside from the tubes (side plates), and brazing portions brazed to the tubes.
  • the coating portion is provided at least on the exposed portion and at positions around the brazing portions of the core plate. Accordingly, the insulating performance on the outer side of the heat exchanger can be effectively improved even when cooling water is used as the coolant.
  • first and second side plates are generally arranged at the outermost fins in the lamination direction for reinforcing to extend in a longitudinal direction of the tubes.
  • at least one longitudinal end portion of each side plate is made of the first insulating material.
  • the one longitudinal end portion of each side plate has a brazing portion brazed to the core plate through a metal part provided on a surface of the longitudinal end portion of each side plate, and the coating portion is provided at a position around the brazing portion of each side plate. Therefore, the outside of the heat exchanger can be accurately insulated from the fuel cell.
  • each side plate is separated from positions where the tubes are brazed to the core plate.
  • the insulating performance of the side plate can be improved.
  • a first metal part bonded to the fins and a second metal part bonded to the core plate are provided on the outer surface of each tube to be separated from each other on the outer surface of each tube. Therefore, an uncovered part made of the first insulating material is formed on the surface of each tube between the second metal part and the first metal part. Accordingly, the insulating performance of the heat exchanger can be readily improved.

  • the radiator 100 cools coolant (cooling water) circulating in the fuel cell 10 , so that temperature of the fuel cell is controlled.
  • the fuel cell 10 is constructed with fuel cell stacks composed of plural cells, and outer casings for accommodating the fuel cell stacks.
  • Each of the cells of the fuel cell stack is formed by inserting an electrolyte film between a plus electrode and a minus electrode so as to generate electrical power by chemical reaction between hydrogen and oxygen.

  • a bypass passage 22 through which the coolant bypasses the radiator 100 is provided in the radiator circulation passage 20 to be parallel to the radiator 100 .
  • the bypass passage 22 is defined by a rubber hose made of an insulating rubber material, for example.
  • a valve 23 is provided at a join portion where the radiator circulation passage 20 at a downstream side of the radiator 100 and a downstream side of the bypass passage 22 are joined. The operation of the valve 23 is controlled by a control unit (not shown), so that a flow ratio between a coolant amount passing through the radiator 100 and a coolant amount passing through the bypass passage 22 can be adjusted.
  • the valve 23 may be provided in a joint portion where the radiator circulation passage 20 at an upstream side of the radiator 100 and an upstream side of the bypass passage 22 are joined.
