Problems solved by technology

However, when used in special environments such as high temperature or low temperature, the heat generation and heat dissipation functions of the mobile phone cannot be balanced. Once the data processing capacity increases or the temperature of the mobile phone will rise above 40°C, the performance of the processor system will be affected by the temperature. If the temperature of the mobile phone is too high, it will damage the mobile phone and even cause the mobile phone to explode, thereby shortening the service life of the mobile phone; in addition, in an environment where the temperature is too low, the power consumption of the mobile phone battery will increase rapidly due to the influence of the low temperature environment. , the standby time of the mobile phone is shortened or even shut down, which affects the normal use of the mobile phone by the user. In order to make the mobile phone run normally, good heat dissipation of the mobile phone and how to maintain the temperature required for the normal operation of the mobile phone battery become particularly important. Due to the limited size of the mobile phone The mobile phone cannot add too many systems for cooling and heat preservation, and the mobile phone case becomes an important auxiliary tool for heat dissipation or heat preservation of the mobile phone
[0003] The design purpose of the mobile phone protective cover is mainly to protect the mobile phone from falling and bumping, to increase the appearance of the mobile phone and to develop and design it from the perspective of heat dissipation or heat preservation of the mobile phone, but the existing ones are designed from the perspective of heat dissipation or heat preservation of the mobile phone. The mobile phone case developed and designed has poor heat dissipation efficiency and complex structure, which is not suitable for the light and portable characteristics of mobile phones.

Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, in one embodiment, a mobile phone case based on phase change materials includes: a case 100, and a polymer material layer 210 disposed on the case 100, and the case 100 includes: a case body 120 and frame 110, the polymer material layer 210 is provided with functional powder; the functional powder contains phase change powder, and the phase change powder is used to absorb and place in the housing 100 by changing the physical form The heat generated by the carrier. Specifically, the mobile phone case based on phase change materials includes: a case 100, and a polymer material layer 210 disposed on the inner side of the case 100, the case 100 includes a case body 120 and a frame 110, so The housing body 120 and the frame 110 are combined to form a cavity for accommodating a carrier, the carrier is a mobile phone, and the housing 100 includes through holes that are compatible with different mobile phone models, and the housing bod...

Embodiment 2

[0030] In one embodiment, the functional powder further includes: temperature-sensitive color-changing powder; the temperature-sensitive color-changing powder is a powder material that changes color as temperature changes. Specifically, the functional powder components contained in the polymer material layer 210 are added to the temperature-sensitive discoloration powder, and the temperature difference is used to control the color change. The temperature-sensitive discoloration powder includes temperature-sensitive microcapsule powder or temperature-sensitive discoloration powder. Masterbatch; usually, the user can only feel whether the mobile phone is hot when it is in contact with the mobile phone. If the mobile phone is overheated during the charging process, the user picks up the mobile phone without knowing it, and it is easy to be burned. potential safety hazards, the temperature-sensitive color-changing particles can visually provide users with mobile phone heating promp...

Embodiment 3

[0032]In one embodiment, the polymer material layer 210 is obtained by pressing the substrate and the adsorption carrier after absorbing various functional powders; the substrate includes: plastic, silica gel or resin; the adsorption carrier includes: air condensation Glue or expanded graphite. Specifically, the functional powder components include phase change powder, heat conduction powder, fragrance powder and temperature-sensitive color-changing powder, according to the phase-change powder, the heat-conducting powder and the temperature-sensitive color-changing powder The specific gravity of the powder is 60-75:15-20:10-20 and mixed uniformly to obtain the functional powder. Exemplarily, according to the phase change powder, the heat conduction powder, the fragrance powder and the The temperature-sensitive color-changing powder is mixed with a specific gravity of 70:20:10 to obtain a functional powder with good heat dissipation and heat storage capabilities; according to t...

Abstract

A mobile phone shell based on a phase change material is characterized in that the mobile phone shell comprises a shell body and a polymeric material layer arranged on the shell body, the shell body comprises a shell body and a frame, and functional powder is arranged in the polymeric material layer; wherein the functional powder comprises phase change powder; the phase change powder is used for absorbing heat generated by a carrier placed in the shell body by changing a physical form; the phase-change powder has the characteristics of approximate constant-temperature energy storage and heat release; the structural characteristics of the mobile phone protection shell are combined; therefore, the mobile phone is protected; the temperature of the mobile phone can be regulated and controlled,so that the mobile phone can run in the optimal design use temperature range and the design performance of the mobile phone can be exerted, the mobile phone can be used in a high-temperature environment or a low-temperature environment without being influenced, the power consumption of a battery is reduced, and the standby time of the mobile phone is prolonged, thereby ensuring the normal work ofthe mobile phone and prolonging the service life of the mobile phone.

Description

technical field [0001] The invention relates to the technical field of mobile phone protective cases, in particular to a mobile phone case based on phase change materials. Background technique [0002] Against the background of the rapid development of the national communication network, mobile phones have become an indispensable communication device in our lives. The hardware of mobile phones is constantly upgraded, and the calculation and processing of tasks performed by them are more complicated. The heat generated by mobile phones is also increasing rapidly. CPU And other chip components will face the threat of overheating. In a normal use environment, the heat generation and heat dissipation of the mobile phone are basically in balance, and the functions of the mobile phone are basically not affected. However, when used in special environments such as high temperature or low temperature, the heat generation and heat dissipation functions of the mobile phone cannot be b...
