Abstract

The utility model relates to a heat absorption type cooling arrangement for gases, the solid body, and semiconductor lasers. Heat-absorbing materials are used for replacing the prior forced water circulation cooling system, and the outer part of the cooling part is sheathed with metal heat radiation fins with high thermal conductivity and ferrules. Gaps remain among fins and are filled with heat-absorbing materials for obtaining the effect of the heat absorption and cooling.

Description

Heat absorption type cooling arrangement

The utility model relates to a kind of heat absorption type cooling device that can be used for gas, solid, semiconductor laser.It uses heat-absorbing material, and the heat dissipation metal fin has replaced original pressure hydrologic cycle cooling system, has obtained safe and reliable good effect.

The type of cooling on the existing laser generally adopts hydrologic cycle cooling system (accompanying drawing 1).It must rely on water pump (5), and water tank (7), radiator (6), water pipe etc. constitute the mobile circulatory system of water.The heat that laser is distributed is taken away and is reached cooling purpose.So its complex structure is bulky, power consumption is big, carries inconvenience.At water pump, all there are the danger of leaking and getting an electric shock in water tank, radiator, water pipe and each join.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of new heat absorption type cooling device is provided.This device is by being sleeved on laser (pipe) heat dissipation metal fin on every side, and becket and filling heat-absorbing material therebetween also has outer container to form.It has substituted the pressure boiler water circulation cooling system of prior art.

The heat dissipation metal fin can be made with the high metal of thermal conductivity.Be aluminum bronze etc.Fin can be made into laser (pipe) parallel axes, also can be made into axis perpendicularly, also can be made into screw type.The power of fin size, quantity and gap length visible lasers (pipe) thereof and thermal discharge thereof size and deciding.

Heat-absorbing material can adopt big heat just can absorb heat and carry out the material of phase conversion when temperature raises,

The heat release heat absorption

Promptly liquid--→ solid-state--→ liquid state

This material is a paraffin.We utilize its thermal capacitance big and have the performance of heat absorption liquefy just, and conversion is not exclusively just got back to solid-state characteristics automatically, is applied to this cooling device and makes heat-absorbing material.

The utility model will be described in further detail in conjunction with following embodiment:

With carbon dioxide (CO ₂) the Gas LASER Tube cover that is example (Fig. 2) around laser tube loads onto and be listed as its gap space filling paraffin (18) of radiating fin made of copper (16) and copper ring (17) (as the interval between fin with also conducting heat) in the lump, when the laser tube heat release, and the paraffin endothermic transition when becoming liquid heat release immediately become solid-stately, facts have proved that this is good heat-absorbing material.

So having than prior art, the utility model is following advantage

1, the utility model reduces the danger of getting an electric shock and bringing because of leaking owing to remove equipment such as water pump, water tank, radiator, water pipe.

2, the utility model volume ratio is less, and is simple in structure, has a style of one's own, and is easy to carry, handled easily.

So 3, the utility model, is operated as animal doctor's Medical Devices owing to remove outdoor that compulsory water circulation system can be in zubzero temperature Celsius, has enlarged range of application, (hold with the north herd the animal doctor district)

4, the utility model is owing to remove equipment such as water pump, water tank, radiator, water pipe, and power consumption lowers greatly, and cost reduces about 25-30%.
