Embodiment Construction

[0019] Such as figure 1 and 2 Shown is an embodiment of the present invention, a dry evaporator, including a tube body 1, the inner cavity of the tube body is divided into two air return chambers 101 and two liquid inlet chambers 102 by a cross-shaped partition plate 100 , so as to form a dual-system dry evaporator, the air return chamber is located above the liquid inlet chamber, the inlet end of the return air chamber located on the same side of the inner cavity of the tube is connected to the liquid outlet end of the liquid inlet chamber, and the pipe body corresponds to the air outlet of the return air chamber There is a tube plate 11 at the end of the tube, and the gas outlets of the two air return chambers can be located at the same end of the tube body, or can be located at both ends of the tube body respectively. The tube plate is connected with a sealing plate assembly 13, and the gas outlet connecting pipe 2 of the fluorine outlet pipe is fixedly connected to the tu...

Abstract

The invention discloses a dry-type evaporator which is a refrigerating system element. The dry-type evaporator solves the oil return problem of an existing evaporator under low flow speed of refrigerating fluid. The dry-type evaporator comprises a pipe body, an inner cavity of the pipe body is divided into an air return cavity and a liquid inlet cavity through a partition plate, the air return cavity is located above the liquid inlet cavity, an air inlet end of the air return cavity is communicated with a liquid outlet end of the liquid inlet cavity, the end portion, corresponding to an air outlet end of the air return cavity, of the pipe body is provided with a pipe plate, the pipe plate is connected with an air outlet connecting pipe which is communicated with the air return cavity, the air outlet connecting pipe is arranged corresponding to the lower portion of the air return cavity, and the height from the center of the air outlet connecting pipe to the partition plate is one fourth to one third the height of the air return cavity. The dry-type evaporator is used in air conditioner refrigerating and heat exchanging.

Description

technical field [0001] The invention relates to an evaporator, in particular to a dry evaporator. Background technique [0002] As one of the four major components of the traditional refrigeration system, the dry evaporator has the inherent disadvantages of high refrigerant flow rate, large fluorine side resistance and difficult distribution of refrigerant, which makes the efficiency of the whole machine much lower than that of the flooded unit. However, due to the mature technology of the dry evaporator, the simplicity of the control system, and the fact that the refrigerant charge is much smaller than that of the flooded machine, the application of the dry evaporator is still irreplaceable for a long time. Existing dry evaporators generally use four tube passes, and those with a diameter of less than 9.52mm use two tube passes, and the flow rate of the refrigerant is above 10m / s to ensure oil return and the fluorine side resistance is relatively large. At the same time, th...
