Description
Technical field
The present invention relates to the technology controlled for electronic device temperature, be specifically related to the seal temperature control equipment being applicable to dissipation from electronic devices field by working fluid.
Background technology
Electronic device in the course of the work, drives a part for the electric energy of these electronic units convert heat energy to and be released.Because the performance of electronic unit has temperature dependency usually, if so the heat discharged can not be discharged in time, bring impact will to the electronic component even performance of electronic device.
Along with the high frequency of electronic device, high speed and integrated circuit constantly develop towards small-sized high density, the power density of electronic devices and components increases substantially, and physical size constantly reduces, density of heat flow rate increases thereupon, the reliability of electronic devices and components work is very responsive to temperature, so the environment of high temperature certainly will affect the performance of electronic devices and components.In order to ensure that electronic devices and components normally work, the good heat radiation of electronic devices and components must be given and its temperature is controlled within the specific limits.
Existing electronic devices and components temperature-controlled process mainly utilizes and comprises heat transfer, convection current radiation, phase place change and Peltier-Seebeck-Thomson effect or be called the principles such as hot spot-effect.
The method that current great majority control electronic component temperature is all realized by gaseous exchange, is namely dispelled the heat by the mode of Forced Air Convection.Or utilize the difference of the heat conductivility of different materials heat is transferred to a larger region from a little thermal source thus realizes heat radiation.Forced Air Convection is the most frequently used heat dissipating method, but because atmospheric density is very low, therefore its coefficient of heat conduction is very low, thus causes radiating efficiency very low.And fluid is because density is higher, can realize higher flow velocity, therefore the efficiency of Heat transmission is also higher.When considering forced convertion Heat transmission mode, the parameter of some fluids will seem particularly important than other parameter under specific system application scenario.The optimal operating temperature range of electronic devices and components be such as operated under electronics calculating occasion is 5-80 degree Celsius, viscosity, heat conductivity, surface tension, resistance are comprised for important parameter fluid, if phase-change liquid, just its boiling point and operating air pressure must be considered.If the space that airtight, optimal operating air pressure scope is usually 1-5 atmospheric pressure (1-5bars).
In " Heat transmission " periodical of 132 phases in 2010, the people such as W.Escher one section be called " apply the experimental study that ultra-thin valve micro-channel heat sink carries out chip fluid heat radiation " and article in, just adopt water to dispel the heat to electronic device, the typical case belonging to above-mentioned theory uses.In this experiment, water does not directly contact with circuit with electronic device, and centre has added one deck medium, forms thermal boundary (thermalbarrier).Other fluids outside water have also carried out similar trial, and she the Pehanorm Mu Dawa as Purdue Univ-West Lafayette USA was once disclosed oily for the immersion of the high energy chip research carrying out dispelling the heat in 1992.Rub the experiment that Cray has also carried out using phase-change liquid to dispel the heat on supercomputer in west, and applied for United States Patent (USP) (patent No. 4590538).
When using liquid to dispel the heat, along with the rising of temperature, just have bubble formation.If particularly the boiling point of this liquid is very low, air bubble problem will be more obvious.If bubble adhesion is on the surface of device, the heat in this region will be taken away in time brings obstruction by convection cell, cause localized hyperthermia.In high-density packages field, spacing between device is very little, the heat produced in unit volume is very high, for improving radiating efficiency, the fluid for radiating heat that usual employing boiling point is very low, in this case, with regard to need to the pressure of this fluid, temperature, flow velocity and bubble prevent carry out precise hard_drawn tuhes, and also do not find the effective solution for the problems referred to above at present.
