Description

Evaporator Having Shelf Faculty For Reach-In Type Shaw Case}

The present invention relates to an evaporator, and more particularly, to a shelf type evaporator of a rich in type showcase installed in a rich in type showcase which is a direct cooling freezer.

Conventional refrigeration and refrigerating devices (hereinafter referred to as 'freezing devices') utilize a cooling action that occurs when a refrigerant, such as a freon, is cycled through a closed loop cycle consisting of a compressor, a condenser, an expansion valve, and an evaporator.

That is, heat exchange is performed in two heat exchangers represented by a condenser and an evaporator by a dynamic cycle called a refrigeration cycle or a refrigerant cycle, and the inside of a refrigerating device such as a refrigerating compartment or a freezing compartment is cooled. The detailed operation materials are as follows.

First, the compressor compresses a refrigerant gas such as CFC (freon) to a high temperature and high pressure state and sends it to the condenser. The condenser forcibly cools the refrigerant gas, releasing heat from the refrigerant gas as much as the latent heat of condensation, and releasing heat to the outside. .

Subsequently, the high pressure liquid refrigerant sent from the condenser is expanded in an expansion valve to be brought into a low temperature low pressure state and sent to the evaporator. The evaporator absorbs the latent heat of evaporation from the air or liquid (water, brine, oil), etc. to be cooled. Cool the surroundings while making the gas gas.

The condenser and evaporator in the refrigeration cycle is usually installed in the case frame of the refrigerating device in consideration of the volumetric ratio of the refrigerating device. In particular, the condenser is installed in the state exposed to the outer wall of the refrigerating device because it has to discharge heat to the outside. Many evaporators are typically installed on the inner wall side of the refrigeration system to facilitate heat absorption from the refrigerated / frozen article.

On the other hand, in the case of the direct-cooling evaporator is installed in the inside of the refrigeration apparatus to directly cool by endotherm by the vaporization of the refrigerant, a typical example of the direct-cooling refrigeration apparatus while storing the beverage, ice cream, meat, etc. in a cold state You can take a showcase that displays your merchandise.

These showcases allow buyers to look at the products displayed inside without opening the door, select the product they want to purchase, and then open the door to take out the selected product. Many of the show-in type showcases are being used.

By the way, the conventional showcase is that the evaporator is stored in the interior of the case, most of the structure consists of a separate shelf in which the goods to be displayed are installed in the interior space.

Therefore, since the display goods and the evaporator in the showcase are not directly in contact with each other, there is a limit to the cooling performance of the evaporator for the display goods to some extent, and the power requirement is increased accordingly.

The present invention was devised to solve the above problems, and the object thereof is a shelf of a rich type showcase, which shows improved cooling performance through direct heat absorption of refrigerated / frozen items in the showcase and can reduce power consumption. To provide a combined evaporator.

Shelf combined evaporator of the rich-in type showcase according to the present invention for achieving the above object, in the rich-in type showcase for displaying refrigerated / frozen goods, the multi-stage Serpentine to be loaded It is made of a tube having a shape, the tube is unitized into two stages each unit is welded, characterized in that the wire is welded to the loading portion of the refrigerated / frozen article.

Here, the heat shrink tube may be fastened to the welded portion of each unit.

In addition, a primary coating film and a secondary coating film may be formed on the surface of the tube, respectively.

In particular, the primary coating film is formed by electrodeposition coating to a thickness of 15㎛ or more, the secondary coating film may be formed by powder coating to a thickness of 30㎛ or more.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in Figure 1, the evaporator of the present invention consists of a tube (1) repeatedly bent several times in a serpentine shape on one coplanar surface, the refrigeration / frozen article is loaded The upper side has a structure in which a plurality of iron wires 2 orthogonal to the longitudinal direction of the tube 1 are welded.

In this way, a set of tubes (1) welded with wires (2) forms a shelf of one stage, and each stage is joined by welding by setting the number of stages appropriate for the size of the showcase to be installed in the future. .

For example, as illustrated in FIG. 2, when a shelf of six stages is to be formed, each unit, that is, three units, is welded to each other by forming one unit of two stages.

In addition, it is preferable that the tube 1 is made of a single wall tube made of steel in consideration of the strength and thermal conductivity of the shelf.

In addition, the welded portion of each unit is preferably wrapped with a heat-shrink tube (3) made of a rubber-like material in order to prevent moisture penetration due to the temperature change of the tube (1) to improve the corrosion resistance.

On the other hand, since the evaporator of the present invention is a direct cooling evaporator, it is preferable to form a coating film on the surface of the tube 1 for corrosion resistance. First, after forming a primary coating film 4 having a high coating ability and a uniform coating film, , The secondary coating film 5 is formed of a polymer resin.

At this time, the primary coating film (4) can be obtained through the electrodeposition coating having a thickness of 15㎛ or more excellent coating and uniform coating, the secondary coating film (5) 30㎛ or more in the thickness of powder coating, in particular Considering the color, it is good to form through white powder coating method.

According to the present invention having the above-described configuration, since the tube 1 is directly installed in the refrigerated / frozen article receiving portion of the showcase, the refrigerated / frozen article and the evaporator tube 1 directly contact each other, and the heat exchange ability is significantly improved. .

In particular, the wire 2 welded to the tube 1 not only reinforces the strength as a shelf but also is made of iron with good thermal conductivity, thereby contributing to the cooling performance.

In addition, the primary coating film 4 and the secondary coating film 5 formed on the surface of the tube 1 complement the corrosion resistance of the tube 1, thereby preventing corrosion of the tube 1 due to moisture or moisture generated in the showcase. Since it is prevented, it does not interfere at all with the function as a shelf.

As described above, the shelf-integrated evaporator of the rich-in type showcase according to the present invention exhibits improved cooling performance through direct heat absorption of the refrigerated / frozen articles in the showcase, and also reduces power consumption.
