Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condenser in a refrigerating cycle used in a refrigerator or the like.

[0002]

2. Description of the Related Art Generally, in a refrigerator or the like, in a condenser in a refrigeration cycle, a condenser pipe is bent in a meandering shape and is arranged on a rear portion of the refrigerator to diffuse heat of the condenser pipe.

However, in the structure in which the refrigerator is arranged in a meandering shape over the entire back surface to radiate heat, hot air is trapped in a gap formed between the refrigerator and the chamber wall, and heat is radiated well. However, there was a drawback that the cooling performance deteriorated.

Therefore, as a refrigerator in which the heat of the condenser pipe can be effectively dissipated to the outside and the cooling performance is improved, for example, Japanese Utility Model Publication No. 61-4220 can be cited.

An example of the refrigerator described above will be described below with reference to the drawings. FIG. 5 and FIG. 6 show an example of a conventional refrigerator, in which 1 is a heat-insulating box body and a compressor 2 is provided in the lower part. The compressor 2 is attached to a compressor mounting plate 3 which is attached across both sides of the heat insulating box 1.
A hot plate 13 is connected to the compressor mounting plate 3 with screws 4. A gap 5 is formed between the outer surface of the heat insulating box 1 and the compressor mounting plate 3. Reference numeral 14 denotes a condenser pipe led out from the compressor 2, which is arranged in the gap 5 and attached to the hot plate 13.

[0006]

However, in the above-mentioned structure, there is a problem that vibration generated by the compressor causes chatter noise between the condenser pipe and the hot plate, and the cost increases. On the other hand, easiness of material selection at the time of disposal has been demanded from the environmental aspect.

In view of the above problems, the present invention provides a low-noise refrigerator that can be effectively dissipated at low cost, can improve cooling performance, and can be easily discarded.

[0008]

In order to achieve the above object, the present invention provides two plates made of a material having good heat conduction in a gap between a heat insulating box and a compressor mounting plate. And a pipe-in type radiator in which a refrigerant passage is formed between the plates.

[0009]

According to the present invention, the pipe-in type heat radiator having the above-mentioned structure and having good heat conduction can improve the heat radiation efficiency. Further, since it is a single component, cost reduction can be achieved and chattering noise can be further prevented. In addition, the disposability can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A refrigerator according to an embodiment of the present invention will be described below with reference to the drawings. In order to avoid duplication of description, the same parts as those of the conventional example will be denoted by the same reference numerals.

In FIG. 1, FIG. 2 and FIG. 3, 6 is a pipe-in type radiator in which a refrigerant passage 7 is formed, which is arranged in the gap 5. The pipe-in type radiator 6 is a pattern of the refrigerant passage 7.
One plate 8 and one plate 9 are printed with an inclusion on the joint surface made of a material having good heat conductivity, and the other plate 9 is superposed, and it is sandwiched between one roll that rolls oppositely. Compressed air is blown between the plates with no pressure contact to form a refrigerant passage 7.

In the refrigerator constructed as described above,
During the cooling operation of the refrigerator, the compressor 2 is activated to radiate the compression heat, and a flow of air rising from the rear side along the back surface of the heat insulating box body 1 occurs.

The air in front of the refrigerator is sucked into the gap 5 through the cool air suction port 10 by being multiplied by this rising air current, and the pipe-in radiator 6 is cooled with fresh air. Since the pipe-in type radiator 6 is a plate having good heat conduction, heat can be radiated on the surface and the heat radiation efficiency can be improved. Further, since it is a single component, chattering noise can be prevented, and further cost reduction and disposal can be improved.

Next, FIG. 4 shows a second embodiment of the present invention. A pipe-in type high-rigidity radiator 12 having a spiral refrigerant passage 11 in which the refrigerant passage has a spiral shape is provided. Rigidity can be achieved and further noise reduction can be achieved without having a vibration mode.

[0015]

As described above, according to the present invention, the pipe-in type radiator is provided in the gap formed so as to communicate with the bottom of the heat insulating box in the front-rear direction and to allow natural convection of air from the front to the rear. By arranging them, there is an effect of enhancing heat dissipation efficiency at low cost. Further, chattering noise can be prevented, and the disposability can be improved.

Further, by making the refrigerant passage spiral, it is possible to increase the rigidity of the pipe-in type radiator and further reduce noise.
