Mining lamp phase change liquid and heat radiator thereof

Abstract

The invention provides mining lamp phase change liquid. The mining lamp phase change liquid is prepared from the following ingredients in parts by weight: 5-80 parts of water, 15-80 parts of anhydrous ethanol and 1-15 parts of edible vegetable oil. The boiling point of the mining lamp phase change liquid is only 45 DEG C, so that the timely release of heat of a mining lamp is guaranteed, and the phenomena of dead lamp, large light decay and the like can not occur. The invention further provides a mining lamp change phase heat radiator using the phase change liquid, wherein the heat radiator comprises a body, a heat conduction plate, a sealing cover plate, a liquid injection tube and the phase change liquid, the middle of the body is provided with a cavity, the two ends of the cavity are respectively connected with the heat conduction plate and the sealing cover plate, the cross section of the heat conduction plate is shaped like the Chinese character 'tu' (shown in a drawing), a protruding portion of the heat conduction plate is tightly connected with the internal wall of the cavity of the body, the bottom portion of the heat conduction plate is connected with the exterior of the body, the liquid injection tube is arranged on the sealing cover plate, and the phase change liquid is filled in the cavity of the body. According to the heat radiator, through arranging a hollow phase change cavity structure, the working area is effectively increased, the heat conducting passage is enlarged, higher power can be realized in the case of the same material and the same volume, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of working condition lighting, in particular to a phase change liquid for working condition lamps and a radiator thereof. Background technique [0002] At present, the radiators of 300W-400W industrial and mining lamps use large-shaped radiators to dissipate heat, and some use thermal phase change radiators to dissipate heat. However, due to its large size, high transportation costs and lack of aesthetics, it is difficult to be accepted by the market. The thermal phase change radiator has the characteristics of small size, light weight, fast conduction and heat dissipation, etc., and is welcomed by the market. [0003] The thermal phase change liquid of the existing thermal phase change radiator needs to reach the boiling point when the temperature of the lamp body reaches 60°C. However, when the temperature rise of the lamp is as high as 40°C, the temperature of the lamp is already high, but the heat sink...

AI Technical Summary

Problems solved by technology

However, when the temperature rise of the lamp reaches 40°C, the temperature of the lamp is already high, but the heat dissipation effect of the radiator has not yet occurred.

When the lamp is used in a high temperature environment, the temperature is too high, prone to dead lights, large light decay, poor lamps and other phenomena
