Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage heat exchanger that stores heat released from a compressor body and uses the heat for defrosting operation, and a compressor provided with the heat storage heat exchanger.

[0002]

2. Description of the Related Art Conventionally, a compressor provided with a heat storage heat exchanger is described in, for example, Japanese Utility Model Publication No. 2-44666.
In addition, as shown in FIG. 7, a compressor main body A having a compression element CP is installed in a heat storage container B, and a plurality of fins F are provided in a space between the heat storage container B and the compressor main body A. It is known that a heat storage heat exchanger D including a heat exchange tube T is housed, the space for housing the heat exchanger D is filled with a heat storage material, and the heat storage container B is sealed. . Then, in this compressor, the heat storage material in the heat storage container B stores the heat of the compressor body A, and the heat of the heat storage material is radiated to the refrigerant flowing through the heat exchange tube T of the heat exchanger D. I have to.

[0003]

However, in the conventional heat storage heat exchanger, the heat storage container B is used and the compressor main body A is provided inside the heat storage container B. It is necessary to form the container B in accordance with the size and shape of the compressor main body A. Therefore, it is necessary to form a dedicated heat storage container B corresponding to the compressor main body A, which is common among models having different capacities. There is a problem that the heat storage container B cannot be converted into the heat storage container B, and the heat exchanger D and the compressor body A are both housed in the heat storage container B, and the heat storage material is filled and then sealed. The heat exchanger had to be formed integrally with the compressor, and the assembling work and the heat storage material filling work were difficult. Further, in the conventional compressor provided with the heat storage heat exchanger, the accumulator E is also installed as shown in FIG. 7, so that the heat storage container becomes very large, and the amount of the heat storage material to be filled inside is used. In addition, as described above, after the heat exchanger D is housed between the heat storage container B and the compressor body A, the heat storage material is filled in the entire gap. In order to prevent the heat storage material from leaking to the outside after that, welding work for sealing the heat storage container B must be performed, so that not only the heat storage material filling work becomes difficult, but also the number of work steps increases, There was also a problem that the workability as a whole was poor and the cost was high. Further, if the heat storage material B is filled with the heat storage material B, the heat storage material B must be opened and the heat storage material must be taken out when the compressor body is repaired, and the work is also extremely difficult. However, there were problems that it became difficult and uneconomical.

The present invention has been made in view of the above problems, and a first object thereof is to provide a heat storage heat exchanger which can be easily manufactured, the manufacturing cost can be reduced, and the range of application can be expanded. The second purpose is to easily attach and detach the heat storage heat exchanger to and from the compressor body without increasing the size of the compressor as a whole. It is to provide a compressor including a heat storage heat exchanger that can reduce the amount of heat and can reduce the cost.

[0005]

The present invention is based on the above-mentioned first aspect.
In order to achieve the purpose of, the bottom plate 51 and the cover plate 52 provided with a plurality of uneven portions 52a, 52b extending in the width direction are combined to form a sheet-shaped heat storage container 5, and the heat storage container 5 is provided with the heat storage container 5. A heat storage heat exchanger is configured by filling the heat storage material 53 and by assembling the heat exchange pipe 6 into the recess 52a of the heat storage container 5 to circulate the heat exchanged material that exchanges heat with the heat storage material 53. .

In order to achieve the above-mentioned second object, the bottom plate 51 and a plurality of uneven portions 52a extending in the width direction,
A heat exchange material that fills a heat storage material 53 in a sheet-shaped heat storage container 5 formed by combining with a lid plate 52 provided with 52b and exchanges heat with the heat storage material 53 in the recess 52a of the heat storage container 5. The heat storage heat exchanger 4 in which the heat exchange pipe 6 for circulating the heat is attached is formed, and the heat storage heat exchanger 4 is curved so that the cover plate 52 is on the inner surface side, and the outer peripheral surface of the casing 11 of the compressor is formed. The compressor was equipped with a heat storage heat exchanger by winding it around and fixing it.

[0007]

The heat storage container 5 is formed into a sheet shape and is filled with a heat storage material in advance, and the heat exchange pipe 6 is assembled in the recess 52a to form the heat storage heat exchanger 4.
Since it can be manufactured separately from the compressor and can be manufactured easily, the manufacturing cost can be reduced. Moreover, since the heat storage heat exchanger 4 is formed in a sheet shape, the heat storage heat exchanger 4 can be made into a compact shape, and can be used in the form of one sheet, used in a stack, or used in a curved shape. Therefore, the range of application can be expanded, and when applied to a compressor, it can be shared by compressors having different shapes and sizes, and parts can be shared.

When the heat storage heat exchanger 4 is curved and wound around the casing 11 of the compressor to form a compressor having the heat storage heat exchanger, the heat storage heat exchanger 4 is simply wound. It can be configured by work, and since it is not necessary to form a heat storage container that seals and internally houses the compressor body and accumulator, it does not increase the size of the entire compressor and the amount of heat storage material used. Can be reduced, and even when repairing the compressor,
By removing the heat storage heat exchanger 4 from the casing 11, the compressor can be easily taken out from the heat storage heat exchanger 4, so that the heat storage material in the heat storage container is removed as in the conventional case. It eliminates the need for work, improves workability, and solves an uneconomical problem.
