Evaporator and air conditioner with same

Abstract

The invention provides an evaporator and an air conditioner comprising the same. The evaporator comprises a shell, a plurality of heat exchange pipes, a plurality of baffle plates and at least one spoiler, wherein the shell is provided with a fluid inlet and a fluid outlet; the heat exchange pipes are arranged in an inner chamber of the shell; the baffle plates are arranged in the inner chamber; the heat exchange pipes are fixedly arranged on the baffle plates; every two adjacent baffle plates form a fluid passage; the baffle plates form a plurality of fluid passages which are communicated with one another; the spoiler is arranged inside one fluid passage and is obliquely arranged between two adjacent baffle plates. A fluid flows along the extension direction of the obliquely-arranged spoiler; with the flowing inertia, the fluid can flow to the back part of each baffle plate. The evaporator and the air conditioner comprising the same, disclosed by the invention, are capable of solving the problem about flowing dead area of the back part of the baffle plate so that the heat exchange performance of the evaporator is improved.

Description

technical field [0001] The invention relates to an evaporator and an air conditioner with the same. Background technique [0002] The dry evaporator is the key heat exchange component of the refrigeration and air conditioning unit. The heat exchange efficiency of the evaporator directly affects the operating characteristics of the entire unit. Therefore, designing an efficient evaporator is conducive to improving the overall performance of the entire system. [0003] At present, the commonly used dry evaporator is a single arc baffle type. The heat exchange efficiency of this evaporator is lower than that of some new heat exchangers, so its internal structure needs to be optimized to improve its heat exchange performance. In the tube side of the traditional dry evaporator, along the flow direction, due to the flow inertia, there is a flow dead zone on the back of each baffle, and the fluid velocity in this dead zone is small (all less than 0.4m / s), and did not flush the tu...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used dry evaporator is a single arc baffle type. The heat exchange efficiency of this evaporator is lower than that of some new heat exchangers, so it is necessary to optimize its internal structure to improve its heat exchange performance.

In the tube side of the traditional dry evaporator, along the flow direction, due to the flow inertia, there is a flow dead zone on the back of each baffle, and the fluid velocity in this dead zone is small (all less than 0.4m / s), and did not flush the tube bundle directly, resulting in that this part of the heat exchange area was not fully utilized
