[0002] With the continuous progress of science and technology and the increasing improvement of people's living standards, the demand for portable refrigeration and heat dissipation equipment gradually increases. Such products were initially designed to provide instant refrigeration or heat dissipation functions in environments without fixed refrigeration or heat dissipation equipment, such as outdoor activities, travel, temporary work sites, etc. Existing portable refrigeration and heat dissipation equipment usually uses a small-sized compressor or a semiconductor refrigeration sheet as the core refrigeration element, and cooperates with a fan and a heat sink to achieve the refrigeration and heat dissipation functions. Although these devices meet the portability requirements to some extent, they still have many limitations in design and performance.

[0003] The existing portable refrigeration and heat dissipation equipment generally has the problem of low refrigeration and heat dissipation efficiency. Traditional equipment mostly uses a single refrigeration or heat dissipation method, which cannot simultaneously and efficiently perform refrigeration and heat dissipation. For example, many devices rely only on fans and heat sinks for heat dissipation, while the refrigeration part relies on refrigerant circulation or semiconductor refrigeration sheets. This separate design results in low overall efficiency. In addition, the structural design of existing equipment is relatively complex, with numerous internal components and unreasonable layout, which not only increases the volume and weight of the equipment, but also increases the manufacturing cost and maintenance difficulty. At the same time, the wind power adjustment function of existing equipment is usually limited, only allowing switching between several fixed gears, which cannot meet the fine adjustment needs of users in different environments.

[0004] Therefore, how to improve the refrigeration and heat dissipation efficiency of portable refrigeration and heat dissipation equipment, simplify the equipment structure to reduce cost and weight, and expand the wind power adjustment range to adapt to different environmental needs has become a technical problem that needs to be solved by technical personnel in the field.

[0036] In another embodiment of the utility model, at least one side wall of casing 1 is bent to the curve of conforming to waist, makes it more conformal to the waist of user, improves cooling effect, wherein " at least one side wall " refers to at least the side wall conforming to the waist of user, namely the side wall embedded with heat conduction sheet 5, simultaneously, the side wall with hanging buckle can also be set to the same shape, makes the whole more beautiful and coordinated.

[0037] In another embodiment of the utility model, heat conduction sheet 5 is used for conducting cold to shell, adopts metal material or ice porcelain material, also can adopt other material with excellent heat conduction performance, wherein, ice porcelain material is a composite material prepared from ceramic powder and ice porcelain filler, realizes the absorption and emission of thermal energy based on the characteristics of material, has good thermal conductivity, heat capacity and adsorption performance, can quickly absorb thermal energy and conduct it to ice porcelain filler, then releases thermal energy through the mode of heat dissipation, realizes the effect of cooling.

[0038] When using, control button 8 controls its working state, such as switch, air volume (motor 9 output power), refrigeration mode (motor 9 opening number, whether semiconductor element 4 works or not), after being turned on, motor 9 output drives fan blade 10 to rotate, air enters casing 1 by lower end surface air inlet 3 of casing 1, and is blown out by upper end surface air outlet 2 of casing 1, forms air circulation, current can pass through semiconductor element 4 at this time, makes it cool down quickly, and carries out heat conduction through heat conduction sheet 5, heat conduction sheet 5 is used to conform to the waist of user, can carry out the rapid cooling of conformal surface.
