Referring to fig. 1, 2 and 4, the charging system of the portable cold and heat storage device of the present invention comprises a temperature adjusting device 10, a plurality of heat conducting structures 20 and a plurality of cold and heat storage boxes 30.
The temperature control device 10 is a device that can continuously absorb heat energy (i.e., cool other objects) or generate heat energy (i.e., heat other objects). In the present embodiment, the temperature control device 10 is a refrigerant evaporator of a refrigeration equipment, and performs cooling by absorbing heat through refrigerant evaporation, but the present invention is not limited thereto, and the temperature control device 10 may be a large amount of cryogenic fluid or an electric heater, for example.
The heat-conducting structures 20 each have two heat-conducting plates 21 arranged at a distance from each other, and each heat-conducting plate 21 is connected to the temperature-regulating device 10. In other preferred embodiments, each heat conducting structure 20 may have only one heat conducting plate 21, and the present invention may have only one heat conducting structure 20.
In the present embodiment, each heat conducting plate 21 includes a fixing portion 211 and a penetrating portion 212 bent relatively. One side of the fixing portion 211 abuts against the temperature adjustment device 10 to ensure that heat can be rapidly transferred between the fixing portion 211 and the temperature adjustment device 10. The penetrating portion 212 extends in a direction away from the temperature adjustment device 10. The two penetrating portions 212 of the two heat conductive plates 21 of each heat conductive structure 20 are parallel to each other. The heat conducting plate 21 is preferably made of a material with good heat conductivity, such as copper, aluminum or graphite.
Referring to fig. 2 to 4, in addition, a plurality of heat pipe installation grooves 213 are formed on each heat conduction plate 21, and a plurality of heat pipes 22 are disposed on each heat conduction plate 21. The heat pipe installation groove 213 extends from the fixing portion 211 of the heat conduction plate 21 to the penetrating portion 212 in close contact with one side surface of the temperature adjustment device 10. Each heat pipe 22 is disposed in a corresponding heat pipe mounting groove 213, and the heat pipe 22 extends from the fixing portion 211 to the penetrating portion 212 of the heat conducting plate 21, and one end of the heat pipe 22 located at the fixing portion 211 directly abuts against the temperature adjustment device 10 to improve the heat conducting effect. More specifically, the heat pipe 22 is a flat pipe body, one of the two opposite side surfaces of which is abutted against the bottom of the heat pipe installation groove 213, and the other side surface of which is abutted against the temperature adjusting device 10, but the heat pipe 22 is not limited to be flat. In addition, the heat pipe 22 is not limited to be disposed in the groove of the heat conducting plate 21, and only the heat pipe 22 contacts the heat conducting plate 21 to increase the transmission speed of the heat energy between the fixing portion 211 and the penetrating portion 212. In other preferred embodiments, each heat-conducting plate 21 can be provided with only one heat pipe 22. In addition, referring to fig. 5, in the second embodiment of the charging system of the portable cold and heat storage device of the present invention, the heat conducting plate 21A may be a plate body made of a material with good thermal conductivity without the heat pipe 22.
Referring to fig. 1 and 4, the cold and heat storage box 30 is filled with a cold and heat storage agent, one side of each cold and heat storage box 30 is recessed to form two heat conduction grooves 31, the two heat conduction grooves 31 are respectively detachably sleeved outside the two penetrating portions 212 of the two heat conduction plates 21 of the corresponding heat conduction structure 20, and the two opposite groove walls of each heat conduction groove 31 respectively abut against the two opposite side surfaces of the corresponding penetrating portion 212, so as to increase the contact area and increase the heat conduction speed. In this embodiment, one of the walls of the heat-conducting groove 31 is directly against one side of the heat pipe 22.
When the utility model is used, the cold and heat storage box 30 to be cooled is aligned to the heat conducting plate 21 sleeved in any heat conducting structure 20 by the heat conducting groove 31. Through practical tests, the cold and heat storage box 30 which is 2 kilograms in weight and has the solidification temperature of minus 23 ℃ can be completely cooled and solidified after about 2 hours. The cooled and solidified cold and heat storage box 30 can be drawn out and placed in the insulation box for low-temperature distribution.
In summary, the present invention forms the heat conduction groove 31 in the cold and heat storage box 30, and inserts the heat conduction plate 21 into the heat conduction groove 31 of the cold and heat storage box 30, so that the cold energy or the heat energy can be rapidly transmitted to the cold and heat storage agent in the cold and heat storage box 30 through the heat conduction plate 21, and the time required for charging the cold and heat storage box can be greatly shortened, and the use is more convenient.
Although the present invention has been described with reference to the preferred embodiments, it is to be understood that the utility model is not limited to the disclosed embodiments, but is intended to cover various modifications, equivalents and alternatives falling within the spirit and scope of the utility model.
