Heat exchange piece of moisture removal device, moisture removal device and clothes dryer

Abstract

The invention provides a heat exchange assembly for a moisture removal device. A heat exchange piece body is provided with a cooling part; the cooling part comprises a containing cavity and a baffle; the baffle is arranged in the containing cavity so that the baffle and the inner contour of the containing cavity can jointly form a cooling channel for a cooling medium to pass through. Wherein the baffle plate is a heat-conducting sheet; at least one baffle is obliquely connected to the inner wall of one side of the containing cavity so as to increase the contact area between the baffle and the cooling medium in the containing cavity. The invention further provides a moisture removal device and a clothes dryer. The baffle and the inner contour of the containing cavity jointly form a cooling channel for a cooling medium to pass through, the space of the cooling channel is enlarged, and therefore the heat exchange effect is improved, and miniaturization design of the cooling part is facilitated. At least one baffle is obliquely connected to the inner wall of one side of the containing cavity, the length of the baffle capable of being contained in the containing cavity is properly increased, then the contact area of the baffle and the cooling medium is increased to a certain degree, and the baffle is a heat conduction piece so as to accelerate the cooling part to transfer absorbed heat to the cooling medium in the cooling channel.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a heat exchange element of a moisture exhaust device, a moisture exhaust device and a clothes dryer. Background technique [0002] With the improvement of people's living standards, users' requirements for clothes dryers are not only cleaning. Due to weather factors, such as the rainy season, the drying time of clothes after washing is long, and some users also need clothes dryers that can dry clothes. . [0003] At present, the dryers on the market are heated by a heater to form hot air, and the hot air is passed into the drying drum through a fan. The air is discharged from the air outlet of the inner cylinder. If the hot and humid air discharged from the inner cylinder is directly discharged to the outside of the dryer, it will have a greater impact on the humidity and temperature of the environment where the dryer is located. Existing clothes dryers dehumidify ...

AI Technical Summary

Problems solved by technology

[0003] At present, the clothes dryers on the market are heated by heaters to form hot air, and the hot air is passed into the drying drum through the fan. The hot air can take away the moisture on the surface or inside of the wet clothes, and then dry the wet clothes, and the formed damp heat The air is discharged from the air outlet of the inner cylinder. If the hot and humid air discharged from the inner cylinder is directly discharged to the outside of the dryer, it will have a great impact on the humidity and temperature of the environment where the dryer is located.

Existing clothes dryers will dehumidify and cool the hot and humid air. Cooling water is usually used to cool the hot and humid air. In order to maintain a certain cooling effect, the cooling channel used to accommodate the cooling water is designed as a curved structure. Take up a lot of space
