Description
Affiliated technical field
The utility model relates to a kind of heat exchanger.Especially this heat exchanger that had not only guaranteed the normal power output of compressor but also can improve heat exchanger effectiveness between air and the cold-producing medium, it can be widely used in refrigeration system and heating.
Background technology
At present, known air conditioner heat exchanger, with the air-conditioner outdoor unit condenser is example, the high pressure-temperature gaseous refrigerant that the compressor normal power comes out is about 80 degrees centigrade, 1.8MPA, warm liquid refrigerant is about 50 degrees centigrade, 1.8MPA in the high pressure that the process condenser comes out, yet ambient air temperature is about 35 degrees centigrade.Because gaseous refrigerant and liquid refrigerant are with pressing in condenser, so during the output of compressor normal power, make the cold-producing medium that comes out through condenser become that warm liquid refrigerant obviously is impossible in about 35 degrees centigrade, the middle pressure of 1.3MPA.As seen fail thoroughly to carry out heat exchange with surrounding air through the cold-producing medium of condenser, raising thermal conversion efficiency wherein helps energy-conservation.
Summary of the invention
Fail to make cold-producing medium and surrounding air for the heat exchanger that overcomes existing condenser and thoroughly carry out heat exchange.The heat exchanger that the utility model relates to had both guaranteed the normal power output of compressor, guaranteed more thorough the carrying out of heat exchange between surrounding air and the cold-producing medium again.
The heat exchanger that the utility model relates to, solving the technical scheme that its technical problem adopts is: with the air-conditioner outdoor unit condenser is example, heat exchanger is by the refrigerant pipe (A3) of high pressure-temperature gaseous refrigerant inlet, be linked in sequence the inlet refrigerant pipe (A8) of warm liquid refrigerant in the outlet refrigerant pipe (A5), throttling arrangement (A6), heat rejection joint (A7), high pressure of warm liquid refrigerant in refrigerant pipe one arranged side by side (A4), the high pressure, refrigerant pipe two (A9) side by side, the outlet refrigerant pipe (A12) of warm liquid refrigerant in the middle pressure; Have perpendicular to the fin (A10) of tube side to arrangement on refrigerant pipe one (A4) and the refrigerant pipe two (A9) arranged side by side side by side, there is the sub-fin (A11) of ring each both sides, fin hole.The refrigerant pipe (A5) of warm liquid refrigerant outlet in the high pressure connects throttling arrangement (A6), connects heat rejection joint (A7), connects the refrigerant pipe (A8) of warm liquid refrigerant inlet in the high pressure again.The heat rejection joint by pad (A21) in the heat rejection at a bolt (A23), two ends (A22), heat rejection fill up outward (A17) (A18) and nut (A15) (A16) forms, refrigerant pipe (A19) (A20) is placed between pad and heat rejection fill up outward in the heat rejection.Screw bolt and nut is by the metal manufacturing of high pressure resistant high temperature, and the outer pad of pad and heat rejection is by the material manufacturing of high pressure resistant high temperature and poor thermal conductivity in the heat rejection.
Condenser just is made up of the zone of two different pressures different temperatures so.Refrigerant pipe one (A4) zone is a warm liquid refrigerant coexistence in high pressure-temperature gaseous refrigerant and the high pressure side by side, and refrigerant pipe two (A9) zone is a warm liquid refrigerant in the middle pressure side by side.Warm area in pressing in setting up independently can further reduce the temperature of cold-producing medium, make in the middle pressure of coming out through condenser warm liquid refrigerant basically with the surrounding air equality of temperature, reach the raising heat exchanger effectiveness, be beneficial to energy-conservation.
Refrigerant pipe one (A4) is positioned at outdoor unit fan of air conditioner (A13) the place ahead side by side, and refrigerant pipe two (A9) is positioned at outdoor unit fan of air conditioner (A13) rear side by side.Be beneficial to gas communication.
The beneficial effect of the utility model heat exchanger is further to have improved the heat exchanger effectiveness between air and the cold-producing medium.
