Cell phone case used in cold region

Abstract

The invention discloses a cell phone case used in a cold region. One side of a soaking plate is a smooth surface and a plurality of fins are arranged on the other side of the soaking plate; an opening is formed in the middle of an upper shell and the smooth surface of the soaking plate is embedded into the opening of the upper shell; a heat insulation element is in a square box body structure; an electric heating chip and a solid-liquid phase change heat accumulation material are arranged in the box body; the solid-liquid phase change heat accumulation material is arranged at the upper end of the electric heating chip; the heat dissipation fins of the soaking plate are inserted into the solid-liquid phase change heat accumulation material; a sealed space is formed by the heat insulation element, the soaking plate and the upper shell; the heat insulation element is arranged in a lower shell; and convex clamping grooves for storing a cell phone are formed in the two edges of the upper end of the upper shell. According to the cell phone case, the heat exchange is carried out by adopting the heat accumulation material and two working states including heat supply and heat dissipation for a cell phone are provided, so that when proper heat is provided for the cell phone so that the cell phone can be normally used under a cold condition, the heat can be dissipated reversely when a machine body of the cell phone is overheated; and the cell phone case has two functions including heat supply and heat dissipation.

Description

technical field [0001] The invention relates to a mobile phone case, in particular to a mobile phone case used in cold regions, which ensures that mobile phone users can normally use the mobile phone for a long time in cold regions. Background technique [0002] Most of the existing mobile phones use lithium batteries, which consist of a positive pole, a negative pole and an electrolyte between the positive and negative poles. The normal operating temperature of lithium batteries is 0-40°C, and the capacitance is greatly affected by temperature. When the temperature is too low, the capacitance of the lithium battery will decrease, and mobile phone users will feel that the mobile phone "consumes power faster"; when the temperature is extremely low, the lithium in the battery will deposit and no longer chemically react with substances , As a result, the internal short circuit of the battery occurs, and the mobile phone with the protection device will automatically stop runnin...
