Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] like Figure 1-3 As shown, according to an embodiment of the present invention, the radiator includes a radiator housing 1, the radiator housing 1 has an inner cavity, an air inlet 2 and an air outlet 3 communicating with the inner cavity, and the radiator also includes a The inner dehumidification assembly includes a first cooling and dehumidification unit 4 .

[0029] By setting the first cooling and dehumidifying part 4 in the radiator shell, the radiator shell cooperates with the first cooling and dehumidifying part 4 to cool down the air flow, make the water vapor in it condense, and form liquid droplets to separate from the air flow. Dehumidification of airflow. Since the air flow is dehumidified in the radiator shell, the condensed liquid droplets can be left in the radiator shell, avoiding the harm caused by the condensation water formed b...

The invention provides a cooling device comprising a cooling device shell, the cooling shell is provided with an inner cavity, an air inlet and an air outlet communicated with the inner cavity, the cooling device further comprises a dehumidification assembly arranged in the inner cavity, the dehumidification assembly comprises a first cooling dehumidification part, and the radiator can be used for dehumidifying to prevent condensation water.

Description

technical field [0001] The invention relates to the field of air-conditioning auxiliary equipment, in particular to a radiator and a frequency converter having the same. Background technique [0002] With the development of the air-conditioning industry and the shortage of energy in the world, the requirements for energy efficiency of air-conditioning are getting higher and higher. Since then, frequency conversion energy-saving technology has been fully applied in air-conditioning. But for high-power inverters, how to efficiently dissipate heat is a challenging problem. [0003] At present, in the frequency conversion industry, the heat dissipation of the inverter usually adopts three forms: fan heat dissipation, refrigerant heat dissipation, or fan plus refrigerant fan heat. The method can efficiently dissipate heat and ensure the normal and reliable operation of the inverter. However, there is a big drawback in the traditional fan plus refrigerant heat dissipation method...
