Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a high-pressure side refrigerant of a refrigeration cycle for cooling the inside of a refrigerator, which is provided in front of a partition wall of a refrigerator partitioned by a partition member. The present invention relates to the structure of a heat conductive plate interposed between the partition plate and the refrigerant pipe when the pipe is disposed as a frost-preventing heating element.

[Prior art]

+i of the partition wall of a refrigerator where the opening is conventionally divided by a partition member
As shown in Fig. 2, the high-pressure side refrigerant pipe of the refrigeration cycle for cooling the inside of the refrigerator is installed as a frost prevention heating element on the ii side, but the heat of the refrigerant pipe is absorbed by the surface of the partition plate. A heat conduction plate, such as an aluminum plate, is interposed between the partition plate and the refrigerant pipes to ensure that the heat is transferred well. However, since the refrigerant pipes are easily deformed during handling, contact with the heat conduction plate is difficult. Since the temperature was not constant, the temperature on the surface of the partition plate was not uniform, and there were cases where the temperature became higher than necessary, and there were cases where exposure occurred partially.

In addition, in order to eliminate the poor contact H < 15 gap B, which is the cause of condensation, it is necessary to have a structure in which the refrigerant pipe is strongly pressed from behind, and a Pressing 7r (5-phase 7') is made of a material that is repellent, and due to the necessity of applying force to the rear surface of the partition plate to correct the deformation of the refrigerant pipe and forceful contact, there is a natural adverse effect. The phenomenon of the partition plate protruding forward creates a gap δ (the gap is not shown), which causes cold air to enter through this gap, creating a vicious cycle that prevents frosting. Although there is a structure in which the conduction plate is made corrugated as shown in FIG. 3 to improve the contact state of the refrigerant pipe, it has not been possible to completely eliminate the drawbacks mentioned above.

[Purpose of the invention]

The present invention has been made with this point in mind.For the refrigerant Q'i, which is easily deformed, the refrigerant pipe is pushed strongly from behind, which means that the heat in the refrigerant pipe can be more reliably absorbed without reducing the manufacturing cost and reducing the manufacturing cost. The shape of the heat conductive plate was devised to allow heat to be transferred to the partition plate.

[Summary of the invention]

The present invention consists of a piece of thermally conductive aluminum foil (approximately 0.1 man) formed into an oval shape, which is easily deformed when the refrigerant pipes come into contact with each other, and has soft upper and lower ends that reliably conduct heat from the refrigerant pipes to the partition plate. plastic i
A rigid drawing part is linearly formed approximately in the center of the aluminum foil formed into an ellipse of τ1 mm to ensure the bulge of the above-mentioned upper and lower soft plastic parts that come into contact with the refrigerant pipe, thereby improving the plasticity of the foil. By combining the linear rigidity with the strength of the drawing part, it eliminates deformation of the heat conductive plate during assembly work, and allows it to be flexibly combined with internal structural members, allowing for excellent exposure of the surface of the partition plate without causing deformation of the partition plate. This provides a structure to prevent attachment.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1, 4, and 5.

In the figure, 1 is the refrigerator box, 2.3 is the inside of the refrigerator, 4 is the partition wall,
5 is a partitioning plate, and 6 is a high-pressure side refrigerant pipe, which is arranged in a U-shape on the front side of the partition wall 4 and serves as a heating element to prevent dew. Reference numeral 7 denotes a member for pressing a refrigerant pipe which also serves as a heat insulating material, and is made of soft polyethylene foam or the like and is fitted in the horizontal and longitudinal direction of the partition wall with an adhesive. 8.9 is the refrigerator door (No. 4
(only the figure is shown), the backing is used to adsorb and seal the partition plate. 10 is a heat conductive structure made of heat conductive aluminum foil (0,
1 mm), formed into an elliptical shape with a bulge dimension of C, and a soft plastic part 10a on the top and bottom that easily deforms due to the characteristics of the foil when a refrigerant pipe comes into contact with it, and a roughly central part formed into an ellipse. Rigid aperture part 1 with horizontal and longitudinal markings on one side
0b is provided. As shown in FIGS. 4 and 5, this rigid drawing part 101) is made of soft plastic before it is assembled into the partition plate; S1
It is assumed that ζ10a serves to prevent lateral deformation by maintaining a constant bulge and J° method C, and after installation, it is assumed to fit between the pitches of the refrigerant pipes arranged in a U-shape.

In other words, the heat conductive structure 10 is a plastic material that easily deforms! l(l
A rigid aperture l″AS101 was provided for the purpose of maintaining the bulge dimension of Oa and C and improving handling properties.
Since the rigid part 10b is provided at a position corresponding to the pitch between the refrigerant pipes, it is buried between the pitches of the refrigerant pipes, so that the rigid part 10b can be connected to the refrigerant pipe. Therefore, the repulsion of the heat conductive structure 10 is only caused by the IIF plastic portion 10a, and no force is generated to lift the partition plate 5 due to the repulsion force.

In addition, the bulge of the plastic part Ill/1° method C is formed by a single heat conductive plate with dimensions that allow the bulge surface to always come into contact with the refrigerant pipe even if the refrigerant pipe is deformed. Even if a gap B' is created, heat is conducted to the partition contact plate contact surface 10c, and a sufficient dew exposure prevention effect can be obtained.

〔Effect of the invention〕

As explained above, the present invention provides a refrigerator in which the interior of a refrigerator box is divided by a partition wall, and the high-pressure side refrigerant pipe of the refrigeration cycle is disposed as a fog lamp heating element in the front part of the partition wall. The heat conduction structure interposed between the high-pressure side refrigerant pipe and the partition plate easily absorbs the deformation of the refrigerant pipe, secures the bulge size of the plastic parts that come into close contact with each other, and improves handling. The required rigidity part is integrally molded, and the rigid constriction part is placed in a position buried between the pitches of the refrigerant pipes.
It does not apply unreasonable repulsive force. For this reason, geothermal conductive members that can provide reliable dew (=1 prevention structure) by flexible combination with internal structural members without creating gaps δ between the partition wall and partition plate that occur in conventional examples, Because of its structure, it has a high quality and economical contribution as a refrigerator partition structure.
