Abstract

The present invention relates to a heat exchanger tube for an evaporator and an evaporator using the same in a refrigerating device. Instead of a circular pipe generally used, an extruded iron or non-ferrous metal and plastic is used to form a heat transfer plate (fin tube) outside the heat transfer tube for refrigerant evaporation. The heat transfer area can be increased to improve heat transfer, and the heating tube is connected to the heating plate for defrosting between the previous heat pipe and the heat pipe, so that the frost generated by the vaporization of the refrigerant can be discharged from the electric heater or the pre-installed refrigerator. The gas was piped to remove the heat by the high pressure gas defrosting method.

Description

Heat pipe and evaporator for evaporator of refrigeration unit {FIN TUVE, EVAPORATOR}

1 is a perspective view of an evaporator heat exchanger tube in which an evaporation heat exchanger tube of two refrigerants extruded and a heating tube are heated by a heat transfer plate;

Figure 2 is a longitudinal cross-sectional view of Figure 1

3 is a single evaporator completed by welding a short end pipe to each end of two refrigerant evaporation heat pipes of the evaporator heat pipe of FIG. 1 or by inserting a separate pipe to expose both ends and expanding or crimping to improve heat transfer.

[Description of Main Code in Drawing]

1: refrigerant tube for evaporation of refrigerant

2: heating tube

3: Heat transfer plate (FIN-FIN TUVE)

4: A pipe in which both ends are exposed and expanded or compressed by inserting welded end pipe or separate pipe at both ends of evaporation heat pipe (use the same drawing)

It is a heat pipe for evaporator of the prefabricated large freezer refrigerator. It uses circular iron or non-ferrous metal pipe as it is, so the heat transfer area is small, the pipe of the heat pipe is long, and the refrigeration unit is turned off for a long time to remove the heat generated during the vaporization of the refrigerant. Spraying water to remove

Two evaporation heat pipes and a heating heat pipe between them are connected to the heat transfer plate, and the heat transfer area is dramatically increased to facilitate heat transfer, provide excellent heat exchange efficiency, and provide defrosting and convenient defrosting. In addition, the present invention is easy to clean, easy to use, strong in dust and foreign substances in the heat exchanger tube for evaporator, and has high durability, and can be used as heat exchanger or condenser of various refrigeration equipment.

According to the present invention, an evaporator can be composed of one evaporator heat exchanger tube as shown in FIG. 3 and a U-shaped bending tube is formed at one end of the evaporator heat exchanger tube by forming two refrigerant evaporator tubes in one evaporator tube. It can be welded and used as the inlet and outlet of refrigerant in the other end direction. Also, one evaporator tube is a bending roller made to fit the external dimensions of the tube for evaporator and bent in U, square or circle. Arrange and combine them in up, down, left and right, and weld or weld the iron or non-ferrous metal and plastic end pipes in advance on the both ends of the evaporator heat pipes and connect them in the field.If necessary, separate iron or non-ferrous metals and plastics are used instead. By inserting the tube, it can be used for good adhesion with expansion pipe, press, pressing roller, etc. When removing the frost, cool the heat pipe of the evaporator. Stop the suspect to operates the electric heater installed in the heating tube for heating or using a solenoid valve is performed to remove the frost to dengue hot gas defrost (HOT GAS DEFROST)

Cooling speed is increased by increasing the heat transfer area of the tube type evaporator tube, reducing the pipe length of the tube for evaporation, reducing material requirements, reducing the compression force of the refrigeration unit, saving electric energy, and installing heating tube for defrosting. By eliminating the frost in the evaporator heat pipe by quickly and conveniently removing it, it is expected to increase the operation efficiency of the refrigerating device and prevent the compressor failure.
