Hereinafter, with reference to the drawings will be described in detail with respect to the Shanghai condenser 500 according to the present invention.

1 is a diagram illustrating a conceptual diagram of a shanghai condenser 500 according to an exemplary embodiment of the present invention.

Shanghai condensing unit 500 according to the present invention comprises an upper chamber 510, the heat dissipation pipe 520 and the lower chamber (530).

The condenser 500 according to the present invention includes a plurality of upper chambers 510, lower chambers 530 disposed below the upper chambers 510, and upper chambers 510 and lower chambers 530 communicating with each other. Made of a heat dissipation pipe part 520.

In the condensation unit 500 according to the present invention, the working fluid may be transferred from the upper chamber to the lower chamber, and vice versa.

When the cooling operation is required, the conveying direction of the working fluid is a direction conveyed from the upper chamber to the lower chamber, which will be described below with reference to this direction.

Therefore, the term 'inflow' is used in the upper chamber 510, and the term 'outflow' is mainly used in the lower chamber 530. However, it is clear that the use of this term can be used in the reverse concept in the reverse conveyance of the working fluid.

In the upper chamber 510 according to the present invention, a passage 511 through which a working fluid flows is formed at one side, and one or more upper connection holes 512 communicating with the heat dissipation pipe part 520 may be formed.

In the lower chamber 530 according to the present invention, a passage 531 through which the working fluid flows out may be formed at one side, and one or more lower transfer holes 532 communicating with the heat dissipation pipe part 520 may be formed.

In the exemplary embodiment of the shanghai condenser 500 according to the present invention, one upper connection hole 512 and one lower connection hole 532 are formed in the upper chamber 510 and the lower chamber 530, respectively, and radiate heat. Pipe portion 520 is the upper end is in communication with the upper connection hole 512, the lower end is preferably formed in a structure that is in communication with the lower connection hole (532) (see Fig. 2).

In another embodiment of the Shanghai-type condensation unit 500 according to the present invention, one upper connecting hole 512 is formed in the upper chamber 510, and a plurality of lower connecting holes 532 are provided in the lower chamber 530. Is formed, the upper end of the heat dissipation pipe 520 is in communication with one upper connection hole 512, the lower end is preferably formed in a structure that is in communication with each of the plurality of lower connection holes (532) (see Figure 3) .

In another embodiment of the Shanghai condenser 500 according to the present invention, a plurality of upper connection holes 512 are formed in the upper chamber 510, and one lower connection hole 532 is provided in the lower chamber 530. The upper end of the heat dissipation pipe part 520 is in communication with the plurality of upper connection holes 512, respectively, and the lower end of the heat dissipation pipe part 520 is preferably formed in a communication structure with one lower connection hole 532 (see FIG. 4). .

In another embodiment of the Shanghai condenser 500 according to the present invention, the upper chamber 510 and the lower chamber 530, respectively, a plurality of upper connection holes 512 and lower connection holes 532 are formed, The upper end of the pipe 520 is in communication with each of the plurality of upper connection holes 512, the lower end is preferably formed in a structure that is in communication with each of the plurality of lower connection holes (532) (see Fig. 1).

In particular, the gas working fluid transferred to the heat dissipation pipe part 520 exchanges heat with the surroundings of the heat dissipation pipe part 520 to change phase into a liquid state. In this process, the working fluid in the liquid state moves faster in the direction of gravity by the load. The working fluid moved to the lower chamber 530 flows out of the condenser through the passage 531.

The heat dissipation pipe part 520 according to the present invention serves to exchange heat between the working fluid and the surroundings. The various embodiments described above may facilitate the transfer of the working fluid, but may facilitate heat exchange with the surroundings. There is an advantage.

On the other hand, in the embodiment shown in Figure 5, due to the structure also communicates between the heat dissipation pipes, even if one heat dissipation pipe is clogged to act to induce the working fluid to another heat dissipation pipe in the middle, there is an advantage that the heat exchange area is increased. .

In addition, since the heat dissipation fin 521 is formed on the outer surface of the heat dissipation pipe part 520 according to the present invention so as to be in thermal contact with the heat dissipation fin 521 which increases the surface area of the heat dissipation pipe part 520, the heat dissipation pipe part 520. ) It exchanges heat with ambient air more smoothly.

In addition, a heat dissipation fan 540 for forcibly transferring air is formed on one side of the condensation part 500 to forcibly transfer air around the heat dissipation pipe part 520 to the heat dissipation pipe part 520. By doing so, the heat exchange of the working fluid conveying the inside of the heat radiation pipe part 520 is more smoothly performed.

The working fluid in the liquid state contained in the liquid chamber 220 having such a structure is the evaporator 210 under the evaporator 210 by capillary forces generated by the transfer channel 230 formed inside the evaporator 210. Move up. The thermoelectric module 100 installed to be in thermal contact with the evaporator 210 and the high temperature unit 110 applies heat to the working fluid in the liquid state to change the working fluid in the gas phase into a gaseous state, and to change the gas into a gaseous state. The working fluid in the state is transferred to the gas phase chamber 240.

At this time, the low temperature unit 120 of the thermoelectric module 100 absorbs heat from the heat sink 310 that is in thermal contact, and the high temperature unit 110 of the thermoelectric module 100 is in the evaporation unit 210 in thermal contact with the high temperature unit 110.
