Problems solved by technology

At present, the commonly used vapor compression refrigeration system requires a large weight and volume to meet the heat dissipation requirements of high-power (ten kilowatts). Machines and fans need to consume about kilowatts of electric energy, so it is difficult to meet the field operation requirements of high-power laser equipment in terms of weight and power consumption

Abstract

The invention discloses a portable laser heat dissipation device. The device comprises a heat transmission module and a heat dissipation module. The heat transmission module is provided with a heat collection assembly and a transmission assembly, and the heat collection assembly is disposed at a heating part of laser equipment, and transmits the heat of the heat collection assembly to the transmission assembly. The heat dissipation module is provided with a heat dissipation assembly and a phase change material, the transmission assembly transmits heat to the heat dissipation assembly, the heatdissipation assembly transmits the heat to the phase change material, and the phase change material absorbs the heat through phase change. The device is good in heat dissipation effect, can realize continuous operation, and is very portable.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation devices, in particular to a portable laser heat dissipation device. Background technique [0002] High-power laser technology has been widely used in optical fiber communication, optical sensing, information storage, laser display, laser medical treatment, laser processing, laser weapons and pumped solid-state lasers and other fields. The high-power laser module generates a lot of heat during the optical output process. If the heat is not dissipated in time, the junction temperature will inevitably rise, which will increase the threshold current of the laser, reduce the efficiency, and cause serious temperature drift of the laser wavelength, making the laser life expectancy decreased. Taking reasonable refrigeration measures and temperature control is the key to the practical application of high-power semiconductor lasers. [0003] In order to achieve portable field operations for high-...
