1. a kind of heat-transferring method based on hot pressing transition effects, it is characterised in that comprise the following steps:

  • Step 1, there is provided a kind of heat transfer system, the heat transfer system has fire end and colling end, between fire end and colling endConnected by least two interface channels, the fire end, colling end and interface channel are rigid element, and are collectively forming oneClosed circulation;

    Step 2, determines operating temperature interval T, and heat-conducting work medium is selected according to operating temperature interval T, makes the heat conductionWorking medium change of corresponding power pressure P in the operating temperature is interval meets:

    And make the heat conductionWorking medium is in gas-liquid two-phase coexisting state in the temperature range T;

    Step 3, to the heat-conducting work medium is filled in the closed circulation, fills the quality of the heat-conducting work medium by formula m=ρ

    1V1

    g(V-V1) determine,Wherein, m fills quality for heat-conducting work medium, and unit is kg,T1Be operating temperature, carry out it is described fill Mass Calculation when, take the maximum temperature and minimum temperature of operating temperature interval TAverage value as T1Temperature, unit for DEG C,V is closed circulation total measurement (volume), and unit is m3,V1It is the work temperature1Under, the liquid volume of heat-conducting work medium, V in the closed circulation1It is chosen for V1=(60%~99%) V, unit is m3

    1It is in the work temperature1When saturation liquid refrigerant density, unit is kg/m3

    gIt is in the work temperature1When saturation gaseous working medium density, unit is kg/m3

    Step 4, the fire end and thermal source are in close contact, and the colling end are contacted with low-temperature receiver or to function of environment heat emission, describedThe liquid heat conductive working medium of fire end is heated generation thermal expansion, forms pressure wave, and pressure wave produces squeezing action to liquid refrigerant, drivesHydrodynamic state working medium circulation flows, and flows to fire end again after flowing to colling end radiating, so circulation, continues hot pressing transition effectsMaintain.
