It will be done.

Thereafter, the evaporated refrigerant flows out from the NONOS refrigerating IIL outlet 24 and returns to the compressor 11. .

Therefore, the cold 117. discharged by the compressor 11. '
The refrigerant is cooled by the heat pipe 13 for heat dissipation in the liquefaction tank 12, and is condensed and liquefied.Since there is no need to pass through a long U-shaped tube passage like in a conventional condenser, there is no loss in pressure 4 of the refrigerant at the heat dissipation part. is a small 4th digit. Furthermore, the 1T medium is depressurized and expanded with the restrictor M14, and the 1T medium is
6, the refrigerant is heated by the heat-absorbing heat pipe 16 and evaporates into vapor, so there is no need to pass through a long U-shaped tube passage like in conventional evaporators, and the pressure loss of the refrigerant at the heat-absorbing part is extremely small. The increase in the required power of the compressor is also reduced by increasing the number of compressors by 1), and compared to the conventional method, the result is 11J or more.

Another embodiment V.1i (C) of the present invention will be described below with reference to the drawings.

Figure 3 is an upper diagram of the liquefaction tank and the heat pipe for heat dissipation in the second embodiment of the present invention. In Figure 3, 25 is the working fluid (Fig. 7A-1- of a plurality of heat dissipation heat pipes 26 sealed with;
Part 26a is a liquefaction tank inserted, and 65 is discharged from a compressor (not shown) into the -1 part with a height of 1'!
II' A gas refrigerant supply 1] 27 for guiding the gas refrigerant of high 11 is provided, and a liquid refrigerant take-out ['128 Or is provided. On the outside of the evaporation part 26a of the heat pipe 26 for heat dissipation, there are many stages of condensation promoting fins 29, which are like a plurality of ridges with sharply tapered tips that promote condensation of the refrigerant.

According to the configuration of this embodiment, the liquid refrigerant (j) flowing into the vaporization tank 32 from the supply port 34 flows into a reservoir and a porous layer so as to soak the entire condensing part of the plurality of heat-absorbing heat pipes 33. Due to the action of 36, the gas refrigerant quickly evaporates and flows out from the gas refrigerant takeout "+35" provided at the top. Therefore, the condensing part of the heat-absorbing heat pipe 33 is always leaking into liquid refrigerant, so the refrigerant is absorbed from the entire surface. In addition to the evaporation of the refrigerant, a method of promoting nucleate boiling such as the porous layer 36 can be used to promote the vaporization of the refrigerant.

As is clear from the description, the air conditioner of the present invention includes a compressor, a liquefaction tank into which the evaporation part of the heat pipe for heat radiation is inserted, a throttle device, a vaporization tank into which the condensation part of the heat pipe for heat absorption is inserted, etc. Since the refrigeration cycle is constructed by connecting the annular V in this order, there is no need to make long pipes for heat exchange in the heat radiation section and the heat absorption section, and the I power loss of the refrigerant is extremely minimized. Therefore, there is almost no increase in the required power of the compressor due to 1-1-power loss, and the thickening coefficient of the air conditioner is greatly improved compared to the conventional one.

In fact, increasing the size of the liquefaction tank and the heat pipe for heat dissipation, and the size of the vaporization tank and the heat pipe for heat absorption is similar to increasing the size of the condenser and evaporation section of a conventional air conditioner, but the present invention's 1114 According to the present invention, the pressure loss of the refrigerant does not increase, and the coefficient of performance of the air conditioner can be effectively improved, which has great practical effects.
