Definitions

  • the present invention relates to a can-type heat exchanger. More particularly, the present invention relates to a can-type heat exchanger which can control temperatures of operating fluids through heat-exchange, improve heat-exchange efficiency, and have reduced weight and size.
  • a heat exchanger transfers heat from high-temperature fluid to low-temperature fluid through a heat transfer surface, and is used in a heater, a cooler, an evaporator, and a condenser.
  • Such a heat exchanger re-uses heat energy or controls a temperature of an operating fluid flowing therein for demanded performance.
  • the heat exchanger is applied to an air conditioning system or a transmission oil cooler of a vehicle, and is mounted in an engine compartment.
  • a conventional heat exchanger controls the temperatures of the operating fluids according to a condition of a vehicle and supplies the operating fluids to an engine, a transmission, or an air conditioning system.
  • bifurcation circuits and valves are mounted on each hydraulic line through which the operating fluids operated as heating medium or cooling medium passes. Therefore, constituent elements and assembling processes are increased and layout is complicated.
  • heat exchanger size of the heat exchanger should be increased in order to improve heat-exchange efficiency. Further, additional valves for controlling flow of operating fluids should be mounted outside, thus constituent elements are complicated and weight and cost are increased. Accordingly, when the heat exchanger is mounted in the engine compartment, layout is complicated and mounting space of the elements is not sufficient.
  • Various aspects of the present invention are directed to providing a can-type heat exchanger formed with a can shape that can control temperature of the operating fluids, improve heat-exchange efficiency, reduce weight and size, simplify an engine layout, and easily obtain mounting space, thus improving installability.

  • a mounting plate may be mounted to the other surface of the cover cap, and a mounting portion may be integrally formed with an exterior circumference of the mounting plate.
  • the can-type heat exchanger can control the temperature of the operating fluids and is formed with a can shape that can improve efficiency of heat exchange and reduce weight and size, and it is thereby possible to simplify an engine layout.
  • manufacturing and assembly working may be simple, manufacturing cost may be reduced, and productivity may be improved as the cover cap to which the heat radiating unit is integrally mounted is coupled with the housing which is manufactured by injection molding.
  • a defective completed product may not be produced such that productivity is improved by checking whether a defective heat radiating unit is produced before the cover cap is assembled therewith.

  • the coolant passes through the first connecting lines 113a from the space S, and the transmission oil flows by the second inlet 131, passing through the second connecting lines 113b. Accordingly, the transmission oil is heat-exchanged with the coolant at the space S of the housing 101, and the temperature of the transmission oil is adjusted.
  • the transmission oil flows from the automatic transmission 40 through the second inlet 131.
  • the flowed transmission oil passes through the second connecting line 113b of the heat radiating unit 110 in the space S and then is exhausted through the second outlet 133, such that the transmission oil is heat-exchanged with the coolant.
  • the transmission oil and the coolant having flowed into the first and second inlets 103 and 131 are heat-exchanged with each other by counterflow as the first and second inlets 103 and 131 are respectively formed at positions intersecting each other at a lateral side of the housing 101 and one surface of the cover cap 130 such that they may be more efficiently heat-exchanged with each other.
  • the transmission oil the temperature of which is raised by operation of the automatic transmission 40, is cooled through heat exchange with the coolant in the heat radiating unit 110 of the can-type heat exchanger 100 and is then supplied to the automatic transmission 40.
  • the can-type heat exchanger 100 supplies the cooled transmission oil to the automatic transmission 40 rotating at a high speed, occurrence of slip in the automatic transmission 40 is prevented.
  • the can-type heat exchanger 100 controls the temperature of the transmission oil such that the coolant and the transmission oil having flowed into the first and second inlets 103 and 131 are heat-exchanged with each other.
  • FIG. 9 is a perspective view of a can-type heat exchanger according to another exemplary embodiment of the present invention.
  • the can-type heat exchanger 200 includes a housing 201, a heat radiating unit 210, and a cover cap 230.
  • the housing 201 includes a first inlet 203 and a first outlet 205.
  • the cover cap 230 includes a second inlet 231 and a second outlet 233.
  • the cover cap 230 includes a coupling portion 235, as described above, and is the same as that of the first exemplary embodiment of the present invention and therefore a detailed description thereof will be omitted.
  • a mounting plate 250 may be mounted to the other surface of the cover cap 230, and a mounting portion 251 may be integrally formed with an exterior circumference of the mounting plate 250.
  • the can-type heat exchanger 200 may be directly mounted to one side of the automatic transmission 40 through the mounting plate 250.
  • the can-type heat exchanger 200 is mounted to one side of the automatic transmission 40 through the mounting portion 251 of the mounting plate 250 mounted to the cover cap 230, thereby eliminating connecting pipes for supplying or exhausting the transmission oil.
  • the can-type heat exchanger 100 and 200 can control the temperature of the operating fluids and is formed with a can shape that can improve efficiency of heat exchange and reduce weight and size, so it is possible to simplify an engine layout.
  • cover cap 130 (and 230) to which the heat radiating unit 110 (and 210) is integrally mounted is coupled with the housing 101 (and 201) which is manufactured by injection molding.
  • the defective complete product may not be produced such that productivity is improved by checking whether a defective heat radiating unit 110 (and 210) is produced before the cover cap 130 (and 230) is assembled therewith.
