Abstract
본 발명은 냉매싸이클을 순환중인 일부 냉매를 바이패스시켜 콘트롤부의 방열판을 방열하므로서 발열량이 큰 전자부품의 파손이나 회로동작상의 오동작을 미연에 방지하도록 한 냉, 난방겸용 공기조화기의 방열장치에 관한 것으로, 냉매가스를 고온, 고압으로 압축시키는 압축기(1)와, 압축기(1)에서 이송된 고온, 고압의 냉매가스를 팬(3)으로 방열시켜 점자적으로 고온, 고압의 액체상태로 상변화시키는 응축기(2)와, 응축기(2)에서 고온, 고압의 액체상태로 상변화되어 이송된 냉매를 저온, 저압의 액체 및 기체상태로 감압하는 제2모세관(4)과, 제2모세관(4)에서 이송된 저온, 저압의 액체 및 기체상태의 냉매가 통과된 뒤 역류되지 않도록 하는 첵크밸브(5)와, 첵크밸브(5)를 통과한 저온, 저압의 액체 및 기체상태의 냉매를 통과시키면서 블로어(7)에 의하여 증발되어 주변열을 빼앗아 외부온도를 낮은 온도로 유지시키는 동시에 증발된 냉매 가스를 다시 압축기(1)로 이송시키도록 하는 증발기(6)와, 제2모세관(4)과 증발기(6)사이에 설치되어 난방운전시 저온, 저압의 액체상태로 감압하는 제1모세관(8)과, 압축기(1), 응축기(2) 및 증발기(6)를 상호 연결하여 냉매의 흐름을 전환시켜서 냉, 난방이 되도록 하는 사방밸브(9)와, 응축기(2) 또는 증발기(6)에서 회수되는 냉매이 액체와 기체를 분리하여 기체냉매만을 압축기(1)로 공급되도록 사방밸브(9)에 연결되는 어큐물레이터(10)와, 제1모세관(8)과 제2모세관(4)사이에 설치되어 냉방운전시 감압된 저온, 저압의 냉매를 바이패스시키도록 개폐되는 조절밸브(11)와, 냉매운전시 제2모세관(4)에서 이송되어 바이패스되는 일부 냉매를 다시 감압하도록 하는 제3모세관(12)과, 제3모세관(12)을 통과하면서 감압된 냉매에 의하여 전자부품(14)의 과열을 방열시킨 뒤 어큐물레이터(l0)로 이송되도록 하는 방열수단(13)으로 냉, 난방겸용 공기조화기의 방열장치를 구성한다.The present invention relates to a heat dissipating device for a cooling / heating air conditioner, which prevents a breakdown of electronic components with a large heat generation amount or a malfunction in a circuit operation by bypassing a circulating refrigerant in a refrigerant cycle, A compressor 1 for compressing the refrigerant gas to a high temperature and a high pressure; and a high-temperature and high-pressure refrigerant gas delivered from the compressor 1 to heat the refrigerant gas into the fan 3, A second capillary tube 4 for decompressing the refrigerant transferred in phase to the high temperature and high pressure liquid state in the condenser 2 to a low temperature and low pressure liquid and gaseous state and a second capillary tube 4 A check valve 5 for preventing the low-temperature, low-pressure liquid and the gaseous refrigerant transferred from the check valve 5 from flowing back after passing through the check valve 5, and a low-temperature, low-pressure liquid and gaseous refrigerant passing through the check valve 5 By the blower (7) An evaporator 6 for evaporating the evaporated refrigerant gas to depress ambient heat to maintain the external temperature at a low temperature and transfer the evaporated refrigerant gas to the compressor 1 and a second evaporator 6 installed between the second capillary tube 4 and the evaporator 6. [ The first capillary tube 8 is connected to the compressor 1, the condenser 2 and the evaporator 6 to switch the flow of the refrigerant to be cooled and heated. And an accumulator (10) connected to the four-way valve (9) so as to separate the refrigerant liquid from the gas and supply only the gas refrigerant to the compressor (1) A control valve 11 installed between the first capillary tube 8 and the second capillary tube 4 to be opened and closed to bypass the low-temperature and low-pressure refrigerant decompressed during the cooling operation, A third capillary tube 12 for reducing the pressure of the refrigerant transferred and bypassed from the first capillary tube 4, A radiator 13 for radiating overheating of the electronic component 14 by the reduced refrigerant passing through the third capillary tube 12 and transferring the refrigerant to the accumulator 10, A heat dissipating device is constructed.
