Description

Exchanger of freezing machine for refrigerator car}

The present invention relates to an exchanger of a refrigeration vehicle cooler, and more particularly, to an exchanger of a refrigeration vehicle cooler for connecting the exchanger in the middle of a cooling cycle to increase the cooling efficiency and heat exchange efficiency to effectively cool the loaded food. will be.

In general, a refrigeration vehicle is a special vehicle that cools the inside of a freezer storage box of a top vehicle type with a cooler to prevent corruption of loaded cargo during movement of the vehicle to maintain freshness.

The cooler is configured to supply cool air into the inside of the loading box by maintaining the coolant at a low temperature through a cooling cycle consisting of compression, condensation, and expansion. Compressed and supplied to the condenser, the condenser cools and liquefies the compressed refrigerant, and the liquefied refrigerant passes through the expansion valve and is maintained at a low pressure that is easy to vaporize. It can be supplied internally.

However, in the condenser, the refrigerant that has undergone condensation contains both gas and liquid, so that the refrigerant containing gas and liquid that has undergone condensation is sent to the expansion valve. There was a problem of poor exchange efficiency.

The present invention has been made in view of the above-described problems, and an object thereof is to provide an exchanger for a refrigeration vehicle cooler that effectively connects an exchanger in the middle of a cooling cycle to increase cooling efficiency and heat exchange efficiency to effectively cool the loaded food. It is in

Features of the present invention for achieving the above object, the compressor 20, the condenser 30, expansion valve 40, the evaporator 50 is connected to each other by a refrigerant pipe to the compression cycle consisting of compression, condensation, expansion In the refrigerator for a refrigerator vehicle configured to supply cold air to the inside of the stacking box, the small cylinder 11 sealed in the center of the sealed large cylinder 12 is inserted into the large cylinder 12 so that the exchanger ( 10) is configured, the first inlet pipe (11a) is inserted into the upper end of the small cylinder 11, the upper end of the small cylinder 11, the first discharge pipe (11b) to the inner bottom of the small cylinder (11) Is inserted and formed, the second inlet pipe 12a is inserted into the lower end of the large cylinder 12, the second discharge pipe 12b is formed is inserted into the upper end, the first inlet pipe (11a) is the condenser 30 The first discharge pipe 11b is an expansion valve 40, the second inlet pipe 12a is an evaporator 50, the second discharge pipe 12b is a compressor 20, and a refrigerant pipe, respectively. It can be achieved by the exchanger of the refrigeration vehicle cooler characterized in that the configuration is connected to.

In the present invention as described above, the exchanger 10 separates the gas and the liquid contained in the condensation gas flowing into the exchanger 10 from the condenser 30 so that only the liquid expands the expansion valve 40. It is possible to effectively freeze loaded foods by increasing the cooling efficiency and heat exchange efficiency.

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

As shown in Figures 1 to 3, the present invention is configured by connecting the compressor 20, the condenser 30, expansion valve 40, the evaporator 50 and the exchanger 10 with a refrigerant pipe.

The exchanger 10 is configured by inserting a small cylinder 11 sealed in the center of the large cylinder 12 in the interior of the large cylinder 12.

The first inlet pipe 11a is inserted into the upper end of the small cylinder 11 on the upper portion of the small cylinder 11 of the exchanger 10.

In addition, the upper portion of the small cylinder 11 is configured by inserting the first discharge pipe (11b) to the inner bottom of the small cylinder (11).

The second inlet pipe 12a is inserted into the lower end of the large cylinder 12 of the exchanger 10, and the second discharge pipe 12b is inserted into the upper end thereof.

The first inlet pipe (11a) is the condenser 30, the first discharge pipe (11b) is the expansion valve 40, the second inlet pipe (12a) is the evaporator 50, the second discharge pipe (12b) The compressor 20 is configured by connecting with refrigerant pipes, respectively.

Referring to the operation of the present invention with such a configuration as follows.

First, when the cooler of the present invention is operated, the compressor 20 operates to circulate the refrigerant. When the compressor 20 sends the compressed refrigerant to the condenser 30, the condenser 30 condenses the refrigerant to form the first of the exchanger 10. It is sent to the inflow pipe 11a.

The condensation refrigerant introduced into the first inlet pipe 11a is separated into gas and liquid in the small cylinder 11, discharges the refrigerant liquid through the first discharge pipe 11b, and is sent to the expansion valve 40.

The refrigerant undergoing an expansion process through the expansion valve 40 supplies heat to the stacker through heat exchange through the evaporator 50.

The refrigerant having undergone heat exchange through the evaporator 50 is introduced into the large cylinder 12 through the second inlet pipe 12a of the exchanger 10, and the refrigerant of the large cylinder 12 passes through the second discharge pipe 12b. It is sent to the compressor 20 through the compression process is sent back to the condenser 30.

The present invention is cooled by such a cooling cycle is to increase the cooling efficiency and heat exchange efficiency.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications may be made without departing from the scope of the invention. It will be understood by those skilled in the art that various changes may be made and equivalents may be resorted to without departing from the scope of the appended claims.
