Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0036] see figure 1 and figure 2 , because after the refrigerant evaporates in the falling film area, there will be a gas-liquid two-phase mixed refrigerant, and the evaporated gas refrigerant is not discharged in time, which interferes with the distribution and uniform dripping of the liquid refrigerant. The present invention provides a can-type evaporator, aiming to solve the above problems. The tank evaporator includes a shell 1, a falling film area 3 is ...

Abstract

The invention provides a tank-type evaporator and an air conditioner, relates to the technical field of air conditioners, and solves the technical problem that liquid distribution of a heat exchange tube in the tank-type evaporator is uneven due to the fact that evaporated gaseous refrigerants interfere with distribution of liquid refrigerants in a falling film area of the tank-type evaporator in the prior art. According to the tank-type evaporator provided by the invention, a gas-liquid separation structure is arranged in the falling film area in the tank-type falling film evaporator, so that a gaseous refrigerant can be discharged from the falling film area in time, the uniformity and the stability of liquid distribution on the falling film area are effectively improved, and the heat exchange efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a tank type evaporator and an air conditioner provided with the tank type evaporator. Background technique [0002] Such as figure 1 As shown, the tank-type falling film evaporator is usually composed of main components such as a shell, an air guide pipe, a first equalizing plate, a second equalizing plate, an upper sealing plate, a lower sealing plate, and a disc heat exchange tube. Such as figure 2 , the heat exchange process is mainly to use the first equalizing plate to evenly distribute the refrigerant from the liquid inlet to the heat exchange tube to form a thin film. The refrigerant liquid film fully contacts the surface of the heat exchange tube and undergoes heat exchange and evaporates. Sometimes In order to further ensure the uniformity of liquid distribution, a second liquid equalizing plate is set up. The unevaporated refrigerant in the first falling fil...
