Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to a heat pipe dehumidifier. Background Art

[0002] The humidity in the oil cave not only accelerates the corrosion of metal equipment such as oil tanks and pipelines, but also erodes the insulation layer of electrical equipment, and accelerates the oxidation and deterioration of oil, affecting the quality of oil products. Therefore, humidity control in oil caves is an important daily task. The existing dehumidification methods for oil caves mainly include: ventilation and dehumidification, but in the southern rainy areas, the air humidity outside the warehouse is relatively high, especially in summer, the air humidity inside and outside the warehouse is often greater than 70% RH; it is necessary to dehumidify the cave.

[0003] The air volume of the dehumidifier is positively correlated with the usage space, but since the cavern is well sealed, if a normal dehumidifier is matched according to the air volume, the installed capacity will be too large. For this reason, we propose a heat pipe dehumidifier. Utility Model Content

[0004] The utility model aims to provide a heat pipe dehumidifier to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat pipe dehumidifier, comprising a base and a body, the body being mounted on the base, a heat exchanger being mounted in the body, the heat exchanger comprising an evaporator and a condenser, the condenser being provided with a heat pipe rear end fin on one side of the evaporator, the evaporator being provided with a heat pipe front end fin on the side away from the condenser, an auxiliary heat pipe being installed between the heat pipe front end fin and the heat pipe rear end fin, the height of the auxiliary heat pipe at one end of the heat pipe front end fin being lower than the height of the auxiliary heat pipe at one end of the heat pipe rear end fin.

[0006] Preferably, a supporting plate is installed in the body, the heat exchanger is installed on the supporting plate, the supporting plate is provided with a confluence groove, and the cross-sectional shape of the confluence groove is triangular.

[0007] Preferably, a compressor and a gas-liquid separator are also provided in the machine body, and the compressor and the gas-liquid separator are both mounted on a supporting plate.

[0008] Preferably, a plurality of air heaters are installed on a side of the machine body away from the front end fins of the heat pipe.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. Add auxiliary heat pipes. The heat pipe is a closed system with lower front fin pipelines and higher rear fin pipelines. Liquid refrigerant will flow into the pipeline of the front fin due to gravity. The front fin is the windward side. The high-temperature air makes the liquid refrigerant evaporate and absorb heat in the front fin pipeline, and change from liquid to gas. The gaseous refrigerant rises and enters the rear fin pipeline of the heat pipe. The high-temperature air passing through the front fin has been initially cooled, and can get a better cooling effect when passing through the evaporator, and the dehumidification effect will also be better. The air cooled by the evaporator passes through the rear fin of the heat pipe again, and the gaseous evaporator in the pipeline is cooled and liquefied, and then returns to the front fin pipeline. The heat pipe does not consume energy during operation, but increases the dehumidification capacity of the dehumidifier, which can reduce the installed capacity of the equipment.
