Abstract
The invention discloses a radiator plate based on composite phase change material, comprising a foam metal plate structure, a phase transition material filler, and other accessory structures. The foam metal plate structure can select a foamed aluminum structure, or a foam copper structure, or other foam metal structures. The phase transition material filler is evenly filled in the gap of foam metal plates. The phase transition temperature of the phase transition material filler is equal to the best temperature of a heater element, and the latent heat of phase transition is quite large. The other accessory structures are heat radiation fans or heating panel supports, disposed on the heating panel. The radiator plate based on composite phase change material is advantageous in that the radiator plate can be used as the heat-radiating base plate for a lap top or as electric appliance element heating panel requiring rapid heat radiation; heat energy can be rapidly absorbed and stored, the surrounding environment of the heating panel can be in an appropriate temperature range for a long time, and thereby damage of lap tops or other heat radiating elements, brought by high temperature can be greatly reduced.
Description
Technical field
The present invention relates to heat transfer and heat management system technical field, relate to a kind of electric elements heat-radiator plate in particular.
Background technology
The high efficiency and heat radiation of electronic and electrical equipment is one of main application of modern heat transfer technology.Traditional radiating mode is the heat radiation that the dependence method of heat convection and the method for air blast cooling carry out to heating electric appliance element, and also bad for the electronic component effect that density of heat flow rate is larger.Phase-change temperature control is as a kind of thermal management algorithm with wide application prospect, receive the very big concern of researcher in recent years, especially be applied in above the passive cooling to the electronic equipment of intermittent or periodic duty, it is advantageous that change in volume scope is little, latent heat of phase change is comparatively large, electronic chip temperature effectively controls by selecting the phase-change material of different phase transition temperature.
The present invention mainly improves existing electric elements heat abstractor.Higher and have in the space of the foam metal of some strength by the phase-change material with larger latent heat of phase change being filled into thermal conductivity, form composite phase-change material.This composite phase-change material thermal conductivity is better, and can absorb storage fast to outside heat, formability is good, can make the cooling requirements that various shape deals with heat radiation elements.
Summary of the invention
Object of the present invention is exactly the deficiency for prior art, and provide a kind of can carry out absorbing to the heat in surrounding environment fast store and the composite phase-change material heat-radiator plate that distributes.The heat that heat radiation elements is operationally distributed is absorbed and distributed, quick reduction ambient temperature, and can when heat radiation elements quits work, the heat that self stores is distributed, the effect of buffering can be played to the heat radiation of components and parts, remain on optimum working temperature when can ensure again components and parts startup next time, considerably increase the useful life of components and parts.
Technology solution of the present invention is as follows: a kind of heat-radiator plate based on composite phase-change material, comprise foam metal plate structure, phase-change material filler and other accessory structures, described foam metal plate structure can select foamed aluminium structure or foam copper structure or other foamed metal structures, described phase-change material filler is uniformly filled in foam metal plate space, the phase transition temperature of described phase-change material filler and the optimum temperature of heater members work are quite and have larger latent heat of phase change, other accessory structures described are be arranged on radiator fan on heating panel or heating panel support.
Preferred as technique scheme, described foam metal plate structure can be foamed aluminium material, foam copper material or other metal foaming materials, and the porosity of foam metal plate can be selected according to the requirement of specific heat load.
Preferred as technique scheme, described foam metal plate structure can be platy structure, and also can be other shapes such as tubular, hemispherical, rectangular channel, the electrothermal component that its shape is dispelled the heat as required requires to determine.
Preferred as technique scheme, described phase-change material filler can be single phase-change material, also can be multiple phase-change material compound.
Preferred as technique scheme, described phase-change material filler can be that the mode heated is filled in foam metal, also otherwise can be filled in foam metal and form composite phase-change material.
Preferred as technique scheme, other accessory structures described, can change the difference of cooling requirements according to radiator operational environment and heat radiation elements, can be the accessory structures such as radiator fan, fin, support.
Beneficial effect of the present invention is: the heat come out during heat radiation elements work, a part distributes in atmosphere, a part is absorbed fast by composite phase-change material radiator, and store, now phase-change material is in phase transition process, due to larger latent heat of phase change, the body temperature of composite phase-change material radiator does not raise, and ambient temperature can be made to be in a temperature be comparatively suitable for components and parts work for a long time.When components and parts quit work and make surrounding environment lower than phase transition temperature time, the heat stored by composite phase-change material radiator can come out, and can make the long-time interior maintenance uniform temperature of surrounding environment.The effect of a buffering can be played like this to the heat radiation of components and parts, also make electric elements be in optimum working temperature when next time starts, make electric elements smooth working.
