Efficient UV (Ultra Violet) curing equipment with cold air flow guide and heat pipe radiation functions

Abstract

The invention discloses efficient UV (Ultra Violet) curing equipment with cold air flow guide and heat pipe radiation functions. The efficient UV curing equipment comprises a shell, an exhaust fan, a heat pipe radiator, an LED (light-emitting diode) light source plate, an air cooler and an air supply device, wherein the exhaust fan is fixed on the outer side of the shell; the heat pipe radiator and the LED light source plate are positioned on the inner side of the shell and are fixedly connected with each other; the air supply device comprises an air supply part and an air guide part, the air supply part is arranged on the outer side of the shell, and the air guide part is arranged on the inner side of the shell and extends out of the outer side of the shell to be communicated with the air supply part; an air guide groove communicated with the air supply part is concavely formed in the bottom of the air guide part; and a plurality of flow deflectors are arranged in the air guide groove. The efficient UV curing equipment with the cold air flow guide and heat pipe radiation functions disclosed by the invention is high in cooling and radiating efficiency, and thus the aging-resisting property of the UV equipment is improved.

Description

technical field [0001] The invention relates to a high-efficiency UV curing device with the functions of cold air guiding and heat pipe cooling. Background technique [0002] Existing UV curing equipment usually installs one or more cooling fans on or near the radiator to achieve the purpose of cooling the equipment by means of draft. Since the performance of UV LEDs is seriously affected by temperature, the heat dissipation design with poor performance cannot take away the heat of the LED light source in time, which will cause the performance of the LED light source to decrease or even be damaged. In addition, since various volatile substances such as UV glue and ink exist in the air during the UV curing process, the open LED light source interface will also age rapidly due to the influence of these volatile substances. [0003] In addition, a general heat pipe radiator usually consists of an integrally formed base, a plurality of columnar extensions and a plurality of coo...

AI Technical Summary

Problems solved by technology

When a fan is used as a heat pipe radiator to dissipate heat, the cooling air will flow from various parts of the heat sink in an irregular manner to take away heat because there is no guide flow, but usually the hottest or most needing heat dissipation may not be able to get enough heat. The air volume dissipates heat, which greatly hinders the heat dissipation efficiency of the heat pipe radiator
