Dehumidifier

Abstract

The invention discloses a dehumidifier. The dehumidifier comprises a main evaporator, an insertion assembly and a heat pipe, wherein the insertion assembly comprises a first clamping plate and a second clamping plate, the first clamping plate is clamped to the end of a first evaporator section, the second clamping plate is clamped to the end of a second evaporator section, the heat pipe is an overall heat pipe and comprises an evaporation section, a condensation section and a middle connecting section, the middle connecting section is clamped between the first clamping plate and the second clamping plate, the evaporation section is located at one side of the insertion assembly, the condensation section is located at the other side of the insertion assembly, the evaporation section is opposite to the first evaporator section, and the condensation section is opposite to the second evaporator section. According to the dehumidifier, through the arrangement of the overall heat pipe, the evaporation section and the condensation section are staggered. On one hand, the structure of the overall heat pipe is conveniently utilized to optimize the layout of the heat pipe, and the problems thata refrigerant in the heat pipe is not uniformly distributed, and conveying strength of a working medium is insufficient are solved; on the other hand, through the staggered arrangement of the evaporation section and the condensation section and in combination with the structure of the main evaporator, air current can flow more smoothly.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a dehumidifier. Background technique [0002] The heat pipe is a high-efficiency heat transfer element designed by integrating the evaporation, condensation and capillary phenomena of the working fluid, with high heat transfer and high temperature uniformity. Heat pipes have been widely used in high-efficiency heat and mass transfer equipment in the fields of chemical industry, power, metallurgy, light industry, glass and ceramics, and the research and application in the field of air conditioning are also deepening. [0003] Air-conditioning heat pipe technology is applied to household dehumidifiers. Two processes are added to the dehumidification model: "heat pipe evaporating end is cooled with equal humidity to return air" and "heat pipe condensing end is used to heat and supply air with equal humidity". The former effectively reduces the sensible heat ratio of return ...

AI Technical Summary

Problems solved by technology

[0004] The dehumidification heat pipe mainly includes a separated heat pipe and an integral heat pipe. In the separated heat pipe, the evaporation end and the condensation end of the heat pipe are respectively located in front of and behind the main evaporator, and are connected by manifolds. The evaporation end and the condensation end of the heat pipe are respectively connected by one or more serpentine tubes. (or U-shaped tube) and combined with fins to form one or more heat exchange modules. The vapor-liquid two-phase working medium in the heat pipe flows in the same direction. It is easy to concentrate superheated gas, so there are obvious defects in vapor-liquid distribution and uneven refrigerant distribution

[0005] In addition, the angle between the manifold and the horizontal direction can only be changed within a certain range. In order to improve the condensate return effect, the separated heat pipe is generally a heat pipe with a liquid core. Its structure is complicated and the manufacturing is cumbersome, which increases the complexity of the heat pipe structure. and production costs
