Temperature.The then steady operation of heater element 5, heat accumulation part 8 is exchanged heat with the evaporator section 4 of heat pipe again, cold in evaporator section 4
Matchmaker absorbs heat and is changed into gaseous state from liquid, due to a certain amount of gaseous coolant be present in evaporator section 4, therefore, the pressure in evaporator section 4
Power is more than the pressure in condensation segment 2, and in the presence of pressure difference, refrigerant is flowed in condensation segment 2 by adiabatic section.In condensation segment 2
Refrigerant exchanged heat with air, heat is distributed into air, refrigerant temperature reduce be changed into liquid after be back to evaporator section 4.
Above-mentioned cyclic process is constantly repeated, is constantly transferred to heat in outside air from heater element 5, reaching reduces heater element 5
The effect of surface temperature.
Power, which sharply increases, during air-conditioning work can cause to produce amount of heat in the heater element short time, and heat pipe
Heat exchange efficiency will not increase therewith, and now, heat accumulation part can absorb and store most of heat caused by heater element, ensure
The use reliability and service life of air-conditioning.
For those skilled in the art it is easily understood that on the premise of not conflicting, above-mentioned each preferred scheme can be free
Ground combination, superposition.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this area
For technical staff, the utility model can have various changes and change.All institutes within spirit of the present utility model and principle
Any modification, equivalent substitution and improvements of work etc., should be included within the scope of protection of the utility model.
