The working principle of the humidifier 11 is as follows: before the air compressor is started, an operator can add cooling water into the housing 111 for pre-cooling treatment, the cooling water sequentially flows through the humidifying component 113 and the heat exchanging component 112 through the water inlet 1113 to humidify dry and cold air in the humidifying component 113 and cool dry and hot air in the heat exchanging component 112 respectively, and the air compressor is started, at this time, the dry and hot air can enter the heat exchanging member 1121 through the air inlet 1111, because the heat exchanging member 1121 is made of a metal material, and the temperature of the cooling water is lower than that of the dry and hot air, heat transfer can occur between the dry and hot air and the cooling water, so as to reduce the temperature of the dry and hot air to the dry and cold air, and because of the pressure effect of the air compressor, the second end 1121b of the heat exchanging member 1121 is conductively connected with the cavity 1161 of the connecting member 116 through a circular hole, so that the cooled dry and cold air can be diffused into the cavity 1161 of the connecting member 116 to perform secondary cooling inside the cavity 1161, the chamber 1161 is also connected to the third end conduction 1131a of the humidifier 1131, that is, the dry and cool air can further enter the humidifier 1131 through the chamber 1161 to be humidified to form wet and cool air, and the wet and cool air can be discharged out of the humidifier 11 through the exhaust port 1112 to perform the next operation.
The utility model provides a humidifier 11 is through inciting somebody to action heat exchange assemblies 112 with humidification subassembly 113 switches on each other and sets up inside same casing 111, makes the dry and hot air can pass through direct entering behind the cooling of heat exchange assemblies 112 humidification subassembly 113 generates wet cold air in order to carry out humidification processing, and heat exchange assemblies 112 and humidification subassembly 113's the mode of setting have improved the conversion efficiency of wet cold air in humidifier 11 promptly to this humidifier 11's the degree of integrating has been improved, makes humidifier 11 need not the mode of setting through external heat exchange assemblies 112 again, can realize carrying out the high efficiency ground humidification to dry and hot air. In addition, in this embodiment, the water inlet 1113 is disposed close to the humidifying component 113, and the water outlet 1114 is disposed close to the heat exchanging component 112, so that the cooling water flows through the humidifying component 113 to humidify the dry and cold air, and then flows through the heat exchanging component 112 to cool the dry and hot air, on one hand, in this process, by disposing one water inlet 1113 and one water outlet 1114 on the shell 111, the heat exchanging component 112 and the humidifying component 113 accommodated in the same shell 111 can share the same water flow, and thus the cooling and humidifying operations can be completed at the same time, and the humidifying cost of the dry and hot air is greatly saved; on the other hand, since the humidification process of the dry and cold air does not increase the temperature of the cooling water, the cooling water is enabled to reduce the temperature of the dry and hot air to the maximum extent to form the dry and cold air according to the heat transfer principle, in other words, the humidification efficiency of the humidifier 11 is further increased.
The foregoing detailed description of the embodiments of the present application has been presented to illustrate the principles and implementations of the present application, and the above description of the embodiments is only provided to help understand the method and the core concept of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
