Description of the Invention: [Technical Field to Which the Invention Is Along] The present invention relates to a device for ray-preserving + lining, and more particularly to an electronic device suitable for an external low-temperature environment.家用 先前 【Prior Art】 Many of the products are installed outdoors, such as wireless base station poles. In cold regions, the temperature in winter is often lowered = below zero. Some electronic parts operating temperatures are above zero, and they will not be able to start up. The problem with the =7 problem is to use resistance heating, so that the system's irt thermal energy will cause the system to reduce heat dissipation. Method: When the line base station encounters a power outage, the system temperature will still drop below zero due to no solar season = heating. Therefore, the wireless base station will not be able to start up immediately after the power is restored. Therefore, the above problems still do not have a complete solution, and innovative solutions to overcome the above problems. / SUMMARY OF THE INVENTION It is an electronic device that is suitable for use in an outdoor low temperature ring and thus in the present invention. According to the above object of the present invention, θ Μ + 4 $ ribs are suitable for the 'child device of the outdoor low temperature ring brother. The electronic device includes an electronic component, a suction component, a heat storage component, and a heat pipe. The heat absorbing element is connected to the electronic component. Storage: Two: Contains "Chemical (four) media. The heat pipe is used to connect the heat-absorbing S piece and the storage. 5 200843630 When the electronic component is in the state of protection, the heat generated by the electronic component is transferred to the phase change heat storage medium stored in the heat storage element by the heat-absorbing element and the heat pipe. When the electronic component is unable to obtain power, the phase change in the heat storage element misplaces the heat and conducts heat to the electronic component by the heat pipe and the heat absorbing element, thereby maintaining the electronic component within an operating temperature range. Therefore, when the electronic device of the present invention is used, the phase change heat storage medium is used to store the heat energy generated in the electronic device when the electronic device is in an operating state, and when the electronic device cannot obtain the power source, the heat energy is released to warm the electronic component to work. Within the temperature range. [Embodiment] The present invention provides an electronic device suitable for use in an outdoor low temperature environment, and the details of the present invention will be described below by way of embodiments. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a diagram showing an electronic device suitable for use in an outdoor low temperature environment in accordance with a preferred embodiment of the present invention. The electronic device 100 can be any electronic device suitable for use in an outdoor low temperature environment (e.g., a base station for wireless communication). The casing 1〇2 of the electronic I set 100 includes a circuit board 1〇4, a heat absorbing element, a heat storage 7G piece and a heat pipe 112. The circuit board 1〇4 has a plurality of electronic components, and the main heat-generating electronic component 1〇6 is provided with a heat absorbing element, which is a metal block 110 in this embodiment. The heat storage element includes a container η4 and a phase change heat storage medium 116. The metal block 110 and the electronic component 1〇6 can be added to the thermal conductive patch 1〇8 to increase the heat transfer efficiency, but the thermal conductive patch i08 is not necessarily necessary. In accordance with a preferred embodiment of the present invention, heat pipe 112 is used to connect metal block 110 to volume Is 114 (heat pipe 112 extends through container U4). The phase change heat storage medium 116 is a heat storage medium for the phase change process reversible and high phase change latent heat, and the melting point of the heat storage medium of 200843630 also needs to be within the operating temperature range of the electronic component (for example, a range higher than the Celsius temperature). The phase change heat storage medium 116 may be paraffin (C^H48) or any heat storage medium meeting the above conditions. The container ι 4 is made of a material which cannot be chemically changed with the phase change heat storage medium 1丨6. 2 is a diagram showing phase changes of a heat storage medium when an electronic component according to the present invention is in an operating state. Please refer to w! and FIG. 2 at the same time. When the electronic component ι〇6 is in the Μ乍 state, the heat generated by the electronic component 1〇6 is transferred to the phase change storage stored in the container 114 by the metal block ιι〇 and the thermal officer 112. Heat medium 丨16. The phase change heat storage medium 116 absorbs heat generated by the electronic component 106 by a phase change when the solid dissolves into a liquid. The time t of the phase change (the amount of endotherm) will be proportional to the amount of phase change heat storage medium 116 (or the capacity of vessel 114). Fig. 3 is a view showing a phase change of a heat storage medium when an electronic component according to the present invention cannot obtain a power source. Please refer to the map at the same time! As shown in FIG. 3, when the electronic component is unable to obtain power, the phase change heat storage medium ff6 in the container 114 releases heat energy, and is conducted to the electronic component 1〇6 by the heat pipe 112 and the metal block 11〇, thereby maintaining the electron 7L#. 1G6 is in the - operating temperature range. At this time, the phase change heat storage medium 116 changes the phase change when the liquid solidifies into a solid to release the amount of ruthenium. According to the above preferred embodiment, the electronic device of the present invention uses the phase change heat storage medium to store the heat energy generated in the electronic device when the electronic device is in the H state, and releases the heat energy when the electronic device cannot obtain the power source. Warm the electronic components to an operating temperature range. Although the present invention has been described above with reference to the preferred embodiments thereof, it is not intended to limit the scope of the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of the warranty of the present invention is defined in the scope of the patent application. BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features, advantages and embodiments of the present invention will become more <RTIgt; An electronic device suitable for an outdoor low-over environment; and Figures 2 and 3 illustrate phase changes of a heat storage device in two different operating conditions in accordance with a preferred embodiment of the present invention.
