Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention will be further described as follows:

[0027] As shown in the drawings, the present invention includes: a fan 1, a heat sink 2 and a UV light source. The fan is used to provide the kinetic energy required for air circulation, and the heat sink is used to absorb and conduct heat generated by a heat source. The surface of the heat sink is coated with nano TiO 2 , nano-TiO 2 Formation of nano-TiO on the surface of heat sink 2 thin film, the nano-TiO 2 It is a water-based coating, which has good photocatalytic oxidation characteristics, and at the same time it has good dispersion, which is convenient for coating on the surface of the substrate; the UV light source is set at the heat sink, which is mainly used to excite nano-TiO 2 photocatalytic oxidation activity, because nano-TiO 2 It needs to absorb ultraviolet light to effectively stimulate its catalytic oxidation activity, so as to achieve the ef...

Abstract

The invention relates to a ventilating and cooling device widely applied to the field of ventilating and cooling of electronic products, machine rooms and base stations, in particular to a ventilating and cooling device with an air purifying function. The device comprises a fan and cooling fins, wherein the fan is used for providing kinetic energy needed for ventilating, the cooling fins are used for absorbing and conducting heat produced by a heat source, the surfaces of the cooling fins are coated with nanometer TiO2, the nanometer TiO2 forms TiO2 films on the surfaces of the cooling fins, a UV light source is arranged on the cooling fins and used for stimulating the photo-catalytic oxidation activity of the nanometer TiO2, the cooling fins are formed by carrying out surface modification treatment on cooling fin base materials, and the surface of each cooling fin is of a micro-hole structure. Compared with the prior art, the device is improved based on an original ventilating and cooling device and has the ventilating and cooling functions as well as the ambient air purifying function, and pollutants in airflow can be efficiently purified through the device.

Description

[technical field] [0001] The invention relates to a ventilation and heat dissipation device, which is widely used in the fields of ventilation, heat dissipation and cooling of electronic products, machine rooms and base stations, in particular to a ventilation and heat dissipation device with air purification function. [Background technique] [0002] At present, conventional ventilation and heat dissipation devices are mainly composed of two parts: a fan and a heat sink. The fan is used to provide the kinetic energy required for air circulation, and the heat sink is used to absorb and conduct the heat generated by the heat source. For heat transfer efficiency, heat sinks are generally arranged densely in fins to provide a larger heat dissipation area in a limited space. However, such existing ventilation and heat dissipation devices only have the traditional functions of ventilation, heat dissipation and cooling, but do not have the function of purifying the ambient air, thu...
