Portion 3210.The air-heater of the embodiment of the present application includes electric-controlled box 34, and the electric-controlled box 34 is housed in the receiving portion 3210 simultaneously
It is fixed to the upper cover 32, efficiently uses space.
The extension 321 is higher than the bottom of the header 20, can prevent having wind without heat exchange in wind field in this way
Device 21, the neutral gear directly through 21 lower part of heat exchanger blow out from the air outlet 1102 of shell 1, influence the refrigeration or heating of air-heater
Effect.Angle between the extension 321 and the main part 320 is greater than 90 degree, be designed in this way be in order to reduce windage,
Since the wind thrown away to the fan blade of wind apparatus 2 is according to recycling clockwise or counterclockwise, being designed in this way can be such that upper cover 32 changes
Changing wind direction is more smooth.The design of the upper cover 32 can play gear wind action, make the water in water receiver 31 will not be by hot wind
The wind field of machine blows to other places.
The application heat-exchange system includes that a pair of of air-heater and the compressor connecting with air-heater (not shown) and throttling fill
Set (not shown).When one of them described air-heater as evaporator refrigeration in application, pass through compressor be discharged high temperature and pressure gas
State refrigerant enters in another air-heater, then is gasificated into the gas-fluid two-phase mixture of low-temp low-pressure then by throttling set
Into the air-heater, that is, evaporator, the refrigerant in the air-heater absorbs heat gasification from the external world at this time, thus by extraneous
Cooling.Refrigerant returns in compressor simultaneously, and circulation carries out above-mentioned absorption refrigeration systematic procedure.
The screen modules 5 of the application air-heater are adsorbed on the outside of first cover plate 4, do not have to open first cover
Plate 4 can remove the screen modules 5 and be cleaned, simple to operate.
