Description
Technical field
The invention belongs to technical field of heat treatment, relate to a kind of portable laser cooling and electric supply installation.
Background technology
The general laser instrument of prior art is all directly to connect mains supply, and inside does not has battery, waits not the most out of doors
The when of having the local use of power supply, in addition it is also necessary to additionally carry battery, therefore use very inconvenient, carry also inconvenient.
Meanwhile, the kind of laser instrument is a lot, and power also varies, the laser instrument that some power is the least, it is not necessary to cooling
Also can normally work.But for powerful laser instrument, if cooling down not in time, it would be possible to can be that laser instrument occurs permanent damage
Bad.The current existing laser instrument cooling following several ways of general employing:
1, air-cooled cooling: with the pumping and the power supply that force wind to cool down laser instrument, sometimes also need to coordinate different fin
Using, the radiating efficiency of which is relatively low, is only applicable to lower-powered laser instrument；
2, cooling by water: cool down laser instrument by the heat convection between coolant and heat sink or other radiating elements.Pass through
Changing heat sink structure, be such as processed into micro-channel heat sink, may increase the cooling effectiveness of which, coolant is directly drained or follows
Ring utilizes, and directly drains and can waste very much resource；Recycling and need bigger amount of liquid, it is the biggest that cooling device typically can do；
3, semiconductor cooling: coordinate with semiconductor chilling plate the mode of water-cooled to cool down, will rise after laser instrument radiating piece
The coolant semiconductor chilling plate of temperature is lowered the temperature, and returns and continues in laser instrument to be cooled to.For high-power laser
Device, size and the power of the semiconductor chilling plate which needs are the biggest.It addition, the Energy Efficiency Ratio of cooling piece is relatively low, therefore transport
Row is relatively costly；
4, compressor cooling: coordinate with compressor assembly the mode of water-cooled to cool down, will heat up after laser instrument radiating piece
Coolant compressor assembly lower the temperature, return and laser instrument continue be cooled to, which and previous mode are deposited
An identical problem: to laser power higher time, need the biggest compressor assembly, therefore use this type of cooling
Superpower laser also can be only placed at fixed location and uses, it is impossible to carry with；
5, compressor directly cools down: the radiating piece of laser instrument is made the evaporimeter of compressor assembly, lowers the temperature directly to laser instrument.
Comparing a kind of mode, which eliminates this intermediate link of coolant, and therefore cooling effect can be improved, but can not
Fundamentally solve the problem that cooling device is excessive.It addition, the temperature of laser instrument is not easy to control by which.
For powerful laser instrument, above several types of cooling all exist or part exist cooling effect not, volume
The problems such as too big and power consumption is the highest.Meanwhile, these types of cooling are cooling in real time to laser instrument, while laser works, cold
But system also must work simultaneously, and therefore cooling system and laser instrument must be one, and laser instrument can not be carried with.
Summary of the invention
Present invention aims to the deficiency of existing laser instrument, it is provided that a kind of rational in infrastructure, good cooling results, use
Conveniently, little and compact the portable laser of power consumption cools down and electric supply installation.
