Description

[Detailed Description of the Invention] - [Field of Application of the Invention] The present invention relates to a refrigeration cycle for a refrigerator-freezer, and its purpose is to prevent the front panel of the refrigerator-freezer from being hemmed and to improve the performance of the compressor. It was done for the purpose of drawing.

[Background of the invention]

A conventional refrigeration cycle will be explained with reference to FIGS. 1 and 2.

, 1 is a box body and a 2Fi front panel.

(The door is omitted). 6 is a compressor, which compresses the refrigerant gas and sends it to the refrigeration cycle, lj: condenser, 5F
It is an i-hot gas pipe, and is embedded in the front panel 2 from point A to point B. 6 is a capillary tube, 7
is an evaporator. 8 is a freezer compartment, and 9 is a refrigerator compartment.

In the conventional refrigerator-freezer configured in this way, the refrigerant gas compressed by the compressor 3 is transferred to the condenser 4, the hot gas pipe 5,
It circulates through the capillary tube 6 and the evaporator 7, and is cooled by the freezer compartment 8, the refrigerator compartment 9, and the evaporator 7. At this time,
The front panel 2 is cooled by heat conduction from the freezer compartment 8 and refrigerator compartment 9, so moisture in the atmosphere condenses and forms dew.
Therefore, a part of the condensation heat is radiated by the hot gas pipe 5 inside the front panel 2, thereby preventing skirting.

In conventional refrigerator-freezers with such a structure, part of the heat of vaporization from the evaporator 7 that escapes through the front panel 2 is discarded into the hot gas pipe 5, and although the efficiency of heat exchange in the condenser 6 is improved, the compression For the machine 6, the amount of heat discarded by the front panel 2 is an extra work, and it has the disadvantage of being inefficient by this amount.

[Purpose of the invention]

The present invention has been made to improve the above-mentioned drawbacks, and the front panel 2 and the compressor 6 are connected by a heat pipe, and a part of the vaporization heat escaping from the front panel 2 is transferred to the compressor 5. By using it for cooling, the front panel 2 is prevented from being exposed to dew, and at the same time, the performance of the compressor 3 is improved.

That is, by piping the heat radiation part of the heat pipe inside the front panel 2 and piping the heat absorption part inside the compressor 5, the refrigerant inside the heat pipe transports the heat of the compressor 6 to the front panel 2 and radiates the heat. This is how it was done. In this way, the tilt of the refrigerant gas sucked into the compressor 6 is lowered, so the amount of refrigerant circulated to the refrigeration cycle can be increased, and the performance of the compressor 6 can be improved. On the other hand, the front panel 2Fi,
Since it is heated by the heat of the compressor 6, dew formation can be prevented.

[Summary of the invention]

The present invention provides piping for a heat nozzle (10) in the front nozzle (2) of the box body (1) of a refrigerated l1trk and inside the compressor (6), and connects it to the piping in the front panel (2). Compressor (6
Embodiment of the Invention The present invention will be described below with reference to an embodiment shown in FIGS. 2 and 6. The same reference numerals as in the conventional example indicate the same thing. 10
is a heat pipe, which is connected to the inside of the compressor 6 and to the front panel 2. 611 is the lower part of the nozzle, which is the lowest part of the piping of the heat pipe 10 and is placed outside the compressor 6. Reference numeral 12 denotes a small diameter section, which is connected to a small diameter constriction of the heat pipe 10 or another small diameter pipe, and is provided above the position of the heat pipe 10 in the compressor 3 . 13゜1
4 is a connection point between the piping inside the compressor 6 and the front nozzle 2.
This is the connection point with the internal piping. 15 is a process pipe, which is a pipe for sealing a refrigerant into the heat pipe 10.

In the refrigeration cooling TLT unit of the present invention configured as described above, the heat pipe 10 piped into the compressor 6 is heated by the compressor 5, so that the liquid refrigerant in the heat pipe 10 is vaporized, and the compressor 3 is used to vaporize the liquid refrigerant. Cooled by heat. The heat taken from the compressor 3 is carried to the front panel 2 by the refrigerant gas rising inside the heat vibrator 10, where it is cooled and radiated as heat of condensation. Therefore, since the front panel 2 is heated by the heat from the compressor 6, it can be maintained at a temperature higher than that at which moisture in the outside air condenses, thereby preventing dew formation. On the other hand, compressor 6
is cooled by the heat of vaporization of the heat pipe 10, which lowers the operating temperature, increases the specific gravity of the refrigerant gas sucked into the cylinder, and increases the amount of circulation.Also, it is possible to reduce the temperature rise of the motor. The lower part 11 of the heat pipe 10 is a liquid refrigerant reservoir in the heat vibrator 10, and the liquid refrigerant stored here is sequentially heated in the compressor 6. The refrigerant condenses and liquefies inside the front panel 2 and drips inside the heat vibrator 10, but in the piping provided with the small diameter pipe 12, the refrigerant drips due to the resistance of the small diameter pipe 12. The liquid refrigerant is stored above the small diameter pipe 12 and then drips into the lower part 11. Therefore, on the small diameter pipe 12 side, only the liquid refrigerant collected above becomes a pressure head, so that the refrigerant gas evaporates in the compressor 6. The refrigerant gas circulates generally in the direction of the arrow shown in FIG. 61 and FIG. Panel 2
A part of the heat of vaporization in the evaporator 7 that was lost in the compressor 6 is transferred to the compressor 6.
Since the heat pipe 10 can be used to cool the front panel 2, the operating efficiency of the compressor 6 can be improved.
When transporting the heat from the compressor 3 to the front panel 2, the heat is transferred to the front panel 2.
Although it is true that it can be transported evenly and easily, condensation on the front panel 2 can be prevented in the same way as with conventional ones.
