Definitions

  • the subject invention relates to a heating, ventilation and air conditioning system (HVAC), and more particularly, to an evaporator apparatus for dissipating heat from the HVAC system.
  • HVAC heating, ventilation and air conditioning system
  • HVAC heating, ventilating and air conditioning system
  • the HVAC system generally includes a blower motor.
  • the HVAC system generally includes a control module such as a linear power module, a pulse width modulator, or a relay resistor module which provides variable speed control of the blower motor.
  • a disadvantage of these control modules is that they generate a significant amount of heat that must be dissipated to conserve the life of the module.
  • a common mode of dissipating heat requires that a heat sink be attached to each power control module, and that the heat sink be inserted into the air flow of the HVAC system to cool the electronic components inside each power control module.
  • An example of a heat sink and a control module as specified is shown in U.S. Patent No. 5,012,656, issued to Yasuji Tamura .
  • the present invention is an evaporator apparatus for dissipating heat from a heating, ventilation and air conditioning (HVAC) system.
  • HVAC heating, ventilation and air conditioning
  • the apparatus includes an evaporator having a first side plate and a second side plate spaced apart and parallel to the first side plate.
  • the invention is distinguished by an electronic circuit for controlling the HVAC system being printed on the first plate of the evaporator.
  • the present invention eliminates the need for a separate resistor card by printing the electronic circuit, i.e., the resistor circuit, on the first plate of the evaporator.
  • the evaporator essentially functions as an effective heat sink thereby eliminating the need to put a resistive speed controller near a throat area of the diffuser.
  • the present invention provides an evaporator apparatus which results in reduced tonal noise output.
  • HVAC heating, ventilation, and air conditioning
  • HVAC system 20 includes a compressor 22 for compressing a refrigerant, and a condenser 24 for receiving the refrigerant from the compressor 22 and condensing the refrigerant.
  • HVAC system 20 also includes an expansion device 25 for receiving the refrigerant from the condenser 24.
  • the expansion device 25 expands the high pressure liquid refrigerant from the condenser 24 into a low pressure liquid and vapor mixture before it enters an evaporator 26 (also referred to throughout as an evaporator 26 apparatus) used for evaporating the refrigerant. More particularly, the evaporator 26 apparatus provides the function of absorbing heat from the air entering the vehicle passenger compartment which will then be dissipated by the condenser 24.
  • the evaporator 26 also has the function of directly absorbing the heat generated during the voltage reduction of the speed controller for the blower motor.
  • a circuit 28 interconnects the compressor 22 and the condenser 24 and the expansion device 25 and the evaporator 26 for directing the refrigerant there through in a particular direction as shown by the arrows bordering the circuit 28.
  • the evaporator 26 has a first side plate 30 and a second side plate 32 that is spaced apart and parallel to the first side plate 30.
  • the evaporator 26 is distinguished by having an electronic circuit 34, also referred to as a resistor circuit or as the blower motor control circuit, for controlling the HVAC system 20 printed on the first side plate 30.
  • the electronic circuit 34 is directly printed onto the first side plate 30 such that the evaporator 26 operates as a heat sink for waste heat that is generated as voltage to the blower is reduced to achieve the various desired speeds.
  • the electronic circuit 34 is covered with an epoxy (not shown) to protect the surface of the electronic circuit 34.
  • the electronic circuit 34 may be covered by other materials suitable for protecting the surface of the electronic circuit 34.
  • the electronic circuit 34 provides variable speed control for the blower motor (not shown) of the HVAC system 20. During operation, the HVAC system 20 generates a substantial amount of heat. The heat is dissipated into the evaporator 26 core.
  • the evaporator 26 also includes an electrical connector 36 that is supported on the first plate 30 and electrically coupled to the electronic circuit 34.
  • a pair of spaced header tanks 38 and tubes 40 extending between the header tanks 38 are further included with the evaporator 26.
  • the side plates 30, 32 of the evaporator 26 interconnect the header tanks 38.
  • the evaporator 26 also includes a plurality of cooling fins 42 that separate the tubes 40 between the header tanks 38.
  • An inlet 44 extends into one of the tanks 38 and an outlet 46 extends from the other tank 38.
