A dehumidification heat exchange device

Abstract

The invention discloses a dehumidification heat exchange device. The dehumidification heat exchange device comprises an air duct, a surface cooler or an evaporator, a first U-shaped heat pipe heat exchanger and a second U-shaped heat pipe heat exchanger, wherein the air duct comprises an air inlet and an air outlet; the surface cooler or the evaporator is arranged in the air duct, the surface cooler or the evaporator (3) is larger than or equal to 600 mm, and an external pipeline is arranged on one side of the surface cooler or the evaporator; the first U-shaped heat pipe heat exchanger is arranged on one side of the external pipeline of the surface cooler or the evaporator, an interval is formed between the first U-shaped heat pipe heat exchanger and the connecting pipeline of a heat insulation area, and the interval is used for being connected with the outside through an external pipeline of the surface cooler or the evaporator; and the second U-shaped heat pipe heat exchanger and the first U-shaped heat pipe heat exchanger are arranged on the other side of the surface cooler or the evaporator in an opposite installation mode, and the pipe diameter of heat exchange pipelines of the first U-shaped heat pipe heat exchanger and the heat exchange pipeline of the second U-shaped heat pipe heat exchanger is 7.0-9.52mm. According to the dehumidification heat exchange device, the structure of the air duct does not need to be changed, so that the transformation risk is reduced, and the modification cost and period are shortened.

Description

technical field [0001] The invention relates to the technical field of dehumidification and drying, in particular to a dehumidification heat exchange device. Background technique [0002] In the field of central air conditioning, constant temperature and humidity air conditioning units are widely used in electronics, machine tools, textiles, medicine and other fields. During operation, the incoming air needs to be cooled and dehumidified first, and then reheated to achieve the required air supply temperature and humidity. Conventional constant temperature and humidity air conditioning units generally use electricity or steam for reheating, which consumes a lot of energy. To reduce energy consumption, heat pipe technology can be used to pre-cool and reheat the air. [0003] Such as Chinese patent CN204026892U. Among them, the Chinese patent uses a U-shaped heat pipe, the pre-cooling pipe of the U-shaped heat pipe on the air inlet side, the evaporator or surface cooler for c...

Problems solved by technology

Therefore, if the existing technology is to be retrofitted with U-shaped heat pipes, the air duct structure needs to be changed, which further increases the risk of retrofitting
