Abstract
The invention discloses an electronic device suitable for outdoor low temperature environment, which includes electronic components, heat absorption components, heat storage components and heat pipes. The heat-absorbing components are connected with the electronic components. The heat storage component includes a phase changeable heat storage medium. The heat pipes are used to connect the heat absorption components and the heat storage components. When the electronic components are in operating status, the heat produced by the electronic components are conducted by the heat absorption components and the heat pipes to store in the phase changeable heat storage medium in the heat storage components. When the electronic components can not get power, the phase changeable heat storage medium in the heat storage components releases heat energy, and conduct to the electron components by the heat absorption components and the heat pipes, thereby sustaining the electron components within an operating temperature range.
Description
Technical field
The present invention relates to a kind of electronic installation and particularly relate to a kind of electronic installation that is applicable to outdoor low temperature environment.
Background technology
Communication product has many open airs that are mounted at present, and for example radio base station can be installed on the electric pole.In some countries, the temperature during winter can be reduced to below the zero centigrade, at this moment, because the electronic component operating temperature that has is above zero, can cause system's running of can't starting shooting.
The known practice that addresses the above problem is to utilize resistance heating, makes system held above zero, but these heat energy that resistance sends can cause the system radiating ability to weaken again.
In addition, if radio base station runs into when having a power failure, system temperature still can be reduced to subzero because of utilizing resistance heating, if during the radio base station telegram in reply, and system's running of still can not starting shooting in real time.
Therefore, the problems referred to above still do not obtain solution completely, and the solution that also needs to innovate is to overcome above-mentioned problem.
Summary of the invention
Technical problem to be solved by this invention is, a kind of electronic installation that is applicable to outdoor low temperature environment is provided.
For achieving the above object, the electronic installation of outdoor low temperature environment that is applicable to provided by the invention comprises: electronic component, heat absorbing element, heat accumulation element and heat pipe.Heat absorbing element connects electronic component.The heat accumulation element is in order to comprise the phase change heat-storage medium.Heat pipe is in order to connect heat absorbing element and heat accumulation element.When electronic component was in running order, hot mat heat absorbing element that electronic component produced and heat pipe conduction were stored to the phase change heat-storage medium in the heat accumulation element.When electronic component can't obtain power supply, this phase change heat-storage medium in the heat accumulation element disengaged heat energy, and mat heat pipe and heat absorbing element conduct to electronic component, and then kept electronic component and be in the operating temperature range.
Therefore, use electronic installation of the present invention, utilize the phase change heat-storage medium when the electronic installation operating state, the heat energy that produces in the stored electrons device, and when electronic installation can't obtain power supply, disengage heat energy with in electronic component to an operating temperature range of heating.
For above and other objects of the present invention, feature, advantage and embodiment can be become apparent, appended graphic being described in detail as follows:
Description of drawings
Fig. 1 is a kind of electronic installation that is applicable to outdoor low temperature environment according to a preferred embodiment of the present invention; And
Fig. 2 and Fig. 3 are that a kind of heat-storing device according to a preferred embodiment of the present invention is in the phase change figure of two kinds of different running situations.
Embodiment
The invention provides a kind of electronic installation that is applicable to outdoor low temperature environment, below mat embodiment is illustrated details of the present invention.
Please refer to Fig. 1, it illustrates a kind of electronic installation that is applicable to outdoor low temperature environment according to a preferred embodiment of the present invention.Electronic installation 100 can be any electronic installation (for example base station of wireless telecommunications) that is applicable to outdoor low temperature environment.Comprise circuit board 104, heat absorbing element, heat accumulation element and heat pipe 112 in the casing 102 of electronic installation 100.Circuit board 104 has a plurality of electronic components, wherein on the electronic component 106 of main heating heat absorbing element is set, and is metal derby 110 at present embodiment.The heat accumulation element comprises container 114 and phase change heat-storage medium 116.Metal derby 110 can add heat conduction paster 108 with electronic component 106, use the efficient that increases heat conduction, but heat conduction paster 108 is not certain necessity.
According to preferred embodiment of the present invention, heat pipe 112 is in order to connect metal derby 110 and container 114 (heat pipe 112 is through to container 114).Phase change heat-storage medium 116 is the heat-storage medium of the reversible and high latent heat of phase change of phase change process, and the fusing point of this heat-storage medium also needs in the operating temperature range of electronic component (scope that for example be higher than 0 degree Celsius) simultaneously.Phase change heat-storage medium 116 can be paraffin (C
23H
48) or any heat-storage medium that meets above-mentioned condition.114 in container is making with the material that phase change heat-storage medium 116 produces chemical changes.
Fig. 2 is according to the heat-storage medium phase change figure of electronic component of the present invention when the operating state.Please be simultaneously with reference to Fig. 1 and Fig. 2, when electronic component 106 was in running order, the hot mat metal derby 110 that electronic component 106 is produced and heat pipe 112 conduction were stored to the phase change heat-storage medium 116 in the container 114.Phase change when phase change heat-storage medium 116 utilizes solid to be fused into liquid absorbs the heat that electronic component 106 is produced.The time t of phase change (amount of heat absorption) can be proportional to the amount (or capacity of container 114) of phase change heat-storage medium 116.
Fig. 3 is the heat-storage medium phase change figure in the time of can't obtaining power supply according to electronic component of the present invention.Please be simultaneously with reference to Fig. 1 and Fig. 3, when electronic component 106 can't obtain power supply, phase change heat-storage mediums 116 in the container 114 disengage heat energy, and mat heat pipe 112 conducts to electronic component 106 with metal derby 110, and then keep electronic component 106 and be in the operating temperature range.Phase change when at this moment, phase change heat-storage medium 116 utilizes liquid to be frozen into solid is to disengage heat.
By above-mentioned preferred embodiment as can be known, use electronic installation of the present invention, utilize the phase change heat-storage medium when the electronic installation operating state, the heat energy that produces in the stored electrons device, and when electronic installation can't obtain power supply, disengage heat energy with in electronic component to an operating temperature range of heating.
