The thermoelectric cooling system comprises the condenser. The inlet end of the condenser is connected with a compressor through an exhaust pipe, the compressor is connected with an evaporator through a gas return pipe, the outlet end of the condenser is connected with a throttling device through a pipeline, the throttling device is connected with the evaporator through a pipeline, and therefore a circulation pipeline is formed. The thermoelectric cooling system is characterized in that a first-stage super-cooling pipe is arranged in the condenser and is connected with a second-stage super-cooling pipe arranged outside the condenser, the second-stage super-cooling pipe is connected with the throttling device through a pipeline and is arranged in a heat pipe heat exchanger, and cooling fins are arranged in the heat pipe heat exchanger. According to the invention, the cooling fins and the heat pipe heat exchanger are arranged for actively cooling the second-stage super-cooling pipe, and the shortcoming that poor heat exchange and different use environment temperature cause change of the super-cooling temperature and then influence the stability of heat exchange and the efficiency of heat exchange is overcome.
Description
Technical field
The present invention relates to a kind of air-conditioning duct cooling system, especially a kind of air-conditioning condenser super cooled sect thermoelectric cooling system.
Background technology
Current processing air-conditioning operationally, first, the gas refrigerant of HTHP is produced by compressor, the gas refrigerant of this HTHP, after outdoor condenser, after being condensed into cryogenic high pressure liquid, directly can enter capillary-compensated, then evaporator evaporation is entered, absorbing environmental atmospheric heat, becomes the gas refrigerant of low-temp low-pressure, and circulation enters compressor operating.
Such circulation, due to not to the liquid refrigerant of the cryogenic high pressure of condensation carried out further cross cold treatment, therefore exist heat exchange efficiency not high shortcoming.
Based on such consideration, domestic air conditioning improved further afterwards, a small amount of heat exchange copper tube is extracted separately out in external condenser bottom, air conditioning chamber, use as supercooling tube, through the high-temperature high-pressure gas refrigerant flowed into chamber external condenser condensation of compressor compresses, be condensed into cryogenic high pressure liquid refrigerant after, then gather, the supercooling tube entering condenser carried out cold again, eventually pass capillary-compensated, flow into evaporator evaporation, the condenser fan that the heat exchange of supercooling tube and condensing heat-exchange share off-premises station carries out heat exchange.
Take supercooling tube cross cold after, although to a certain degree improve heat exchange efficiency, because super cooled sect is in condenser device bottom, therefore there is heat exchange bad, environment for use temperature is different and cause degree of supercooling variations in temperature, thus affects the stability of heat exchange, finally affects the defect of heat exchange efficiency.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of air-conditioning condenser super cooled sect thermoelectric cooling system improving heat exchange efficiency.
This system comprises a condenser, condenser inlet end connects compressor by blast pipe, compressor connects evaporimeter by muffler, the port of export of condenser connects flow controller by pipeline, flow controller connects evaporimeter by pipeline, form circulation line, its improvement is: be provided with one-level supercooling tube in described condenser, described one-level supercooling tube is connected with the secondary supercooling tube being located at condenser external, described secondary supercooling tube is connected to flow controller by pipeline, described secondary supercooling tube is arranged in a heat exchange of heat pipe, cooling piece is provided with in described heat exchange of heat pipe.
Preferably, described one-level supercooling tube and secondary supercooling tube are plate-like pipeline.
Preferably, the cold junction that the cold junction of described cooling piece fits in secondary supercooling tube, the hot junction laminating of cooling piece is installed on heat exchange of heat pipe.
Owing to have employed said structure, cooling system of the present invention is by arranging cooling piece and heat exchange of heat pipe carries out active cooling to secondary supercooling tube, avoid heat exchange bad, environment for use temperature is different and cause degree of supercooling variations in temperature, thus affect the stability of heat exchange, finally affect the defect of heat exchange efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, the cooling system of the present embodiment comprises a condenser 1, condenser 1 arrival end connects compressor 6 by blast pipe 2, compressor 6 connects evaporimeter 9 by muffler 7, the port of export of condenser 1 connects flow controller 8 by pipeline, flow controller 8 connects evaporimeter 9 by pipeline, form circulation line, its improvement is: be provided with one-level supercooling tube 3 in described condenser 1, described one-level supercooling tube 3 is connected with the secondary supercooling tube 5 being located at condenser 1 outside, described secondary supercooling tube 5 is connected to flow controller 8 by pipeline, described secondary supercooling tube 5 is arranged in a heat exchange of heat pipe 11, cooling piece 10 is provided with in described heat exchange of heat pipe 11.
In the present embodiment, described one-level supercooling tube 3 and secondary supercooling tube 5 are plate-like pipeline.
In the present embodiment, the cold junction that the cold junction of described cooling piece 10 fits in secondary supercooling tube 5, the hot junction laminating of cooling piece 5 is installed on heat exchange of heat pipe 11.
During work, the high-temperature high-pressure gas refrigerant that compressor 6 compresses, by blast pipe 2, enters in condenser 1 in heat exchange copper tube, is condensed into the liquid of cryogenic high pressure with cold air after carrying out heat exchange.Be condensed into the liquid of cryogenic high pressure, enter in the 1 grade of supercooling tube 3 be built in condenser 1 and proceed to cool (excessively cold).Completing 1 grade of excessively cold refrigerant liquid enters in the 2 grades of supercooling tubes 5 be embedded in aluminum heat exchanger 4, by the cold that the cooling piece 10 be close on aluminum heat exchanger 4 produces, by heat conducting mode, carry out heat exchange with cold-producing medium in the 2 grades of supercooling tubes 5 be embedded in aluminum heat exchanger 4, continue cooling refrigeration agent.Complete the liquid refrigerant of 2 grades of coolings, flow out 2 grades of supercooling tubes 5, after flow controller 8 throttling, enter evaporimeter 9 and evaporate, the heat in absorbing environmental air, reach and regulate air object.The cold-producing medium completing heat exchange in evaporimeter 9 becomes the gas of low-temp low-pressure, enters compressor 6 and compresses, circulate through muffler 7.The cold junction of heat exchange of heat pipe 11 is close in the hot junction of cooling piece 10, and the heat that cooling piece 10 work produces is taken away by the cold junction of heat exchange of heat pipe 11, and passes through hot junction and the cross-ventilation of heat exchange of heat pipe 11, completes heat exchange cooling.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
