Description

The sheet metal apparatus of heat resistance test

Technical field

The utility model relates to a kind of testing apparatus, relates in particular to a kind of sheet metal apparatus of heat resistance test that is applied to.

Background technology

Soaking plate (vapor chamber) like sheet metal is to inject working fluid in the vacuum cavity on the market; Rapid and uniform spreads to the condensation of low temperature place after receiving thermal evaporation, is back to thermal source by the capillary structure in the cavity again, is close to the action of repeated evaporation/condensation in the ultrasonic speed operation; In the extremely short time, get rid of a large amount of heat energy; Be uniquely in the market to deserve to be called short, little, light, thin, and speed is fast, prominent passive type heat loss through conduction element; It has characteristics such as needn't keep in repair, sturdy and durable, inexpensive and plasticity is big; Can process different size, shape because of customer demand provides all circles to use, and except can be applicable to computer and peripherals thereof, the important relatively radiating module trends of design of illumination optical elements such as LED and OLED also is following its developing direction.

Electronic product is design focal point with compact all at present, and along with the reduction of volume, the space of chip is compressed littler narrower, and the heat that unit volume comes out is multiplication relatively also.Central processing unit with computer is an example, and heat energy is improving five times during the decade.But regrettably present traditional radiating subassembly, still chase after be unable to catch up with the central processing unit smaller volume after, the heat energy that power strengthens.Present radiating mode also can only be made an issue of in the radiating fin design except strengthening fan dimension, revving up for a short time, and the effect of above-mentioned many radiating modes is all not satisfactory, and the positive heat that at all can't satisfy behind power, the enhancing efficiency is distributed demand.

Temperature-uniforming plate (Vapor Chamber) has capillary structure in it, can the heat of evaporation rapid and uniform of heat conducting medium in the hollow cavity be spread to the condensation of low temperature place, is back to thermal source by the capillary structure in the cavity again; The action of repeated evaporation/condensation; In the extremely short time, get rid of a large amount of heat energy, temperature-uniforming plate is the most reliably not have the passive type cooling device that consumes energy, and it is sturdy and durable, needn't keep in repair; Can be made into different size on demand; Can extensively be used on the heat radiation purposes of electronic product, temperature-uniforming plate will replace the traditional heat-dissipating element in a short time fully, and become the main flow of heat dissipation element in the future.

Yet,, in the process of producing, tend to cause its heat transfer property not reach expection like the temperature-uniforming plate of sheet metal because many factors produce flaw, bad etc. like powder sintered control.Therefore; Industry was once developed a kind of pick-up unit; It has a data recorder pick-up unit, and this data recorder also has an infra red thermograph and a calculation element, and pick-up unit distributes through the thermal source of infra red thermograph check like the temperature-uniforming plate of sheet metal; Carry out the data conformity analysis again, its thermal source that detects temperature-uniforming plate can't reach accurate.
