Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
As shown in fig. 1 to 3, a temperature control structure for a luggage includes a fixing main body 1, and a plurality of semiconductor chilling plates 2 located on the fixing main body 1, wherein the area of the fixing main body 1 is much larger than the total area of the semiconductor chilling plates 2, so as to provide conditions for the heat dissipation of the semiconductor chilling plates 2; fixed main part 1 is equipped with heat conduction reflection stratum 11, thermal-insulated filling layer 12 and precoat 13, and in-service use heat conduction reflection stratum 11 is the aluminium foil, and thermal-insulated filling layer 12 is located between heat conduction reflection stratum 11 and the precoat 13, and semiconductor refrigeration piece 2 inlays on heat conduction reflection stratum 11 and thermal-insulated filling layer 12. Specifically speaking, the semiconductor refrigeration piece 2 is connected with a control assembly, and the control assembly comprises a controller, a battery, a relay, a temperature sensor, a USB input socket and a charging circuit. The controller links to each other with battery, relay, temperature sensor respectively, and semiconductor refrigeration piece 2 links to each other with relay, temperature sensor respectively, and charging circuit links to each other with battery, USB input socket respectively, and temperature sensor sets up on semiconductor refrigeration piece 2, and controller, battery, relay, charging circuit are for setting up an integrated circuit board, are located by USB input socket. The plurality of semiconductor refrigerating pieces 2 are distributed on the fixing main body 1 in an array mode. When refrigeration is needed, the battery controls the semiconductor refrigeration piece 2 to refrigerate through the controller, the temperature sensor detects the refrigeration temperature and feeds the refrigeration temperature back to the controller, and when the electric quantity of the battery is insufficient, the battery can be connected with an external power supply through the USB input socket to charge the battery; when needs heating, the controller control semiconductor refrigeration piece 2 heats, and temperature sensor detects the refrigeration temperature and feeds back to the controller, and when the battery electric quantity was not enough, accessible USB input socket connects external power source and charges for the battery.
Specifically, the semiconductor refrigeration piece 2 is provided with a heat dissipation part 21 and a heat conduction part 22, the heat dissipation part 21 is located at the bottom of the semiconductor refrigeration piece 2 and is bonded to the semiconductor refrigeration piece 2 through heat dissipation silicone grease, and the heat conduction part 22 is welded to the heat dissipation part 21. The semiconductor refrigerating sheet 2 is wrapped by waterproof insulating plastic, namely the semiconductor refrigerating sheet 2 and the heat radiating part 21 are soaked in waterproof insulating plastic solution and taken out, only the heat conducting piece 22 is exposed, and the heat conducting piece 22 extends to other parts of the fabric layer 13
Preferably, the heat conducting member 22 is a metal wire or a graphene heat dissipating wire, and the metal wire or the graphene heat dissipating wire is attached to the fabric layer 13. Let the metal wire or graphite alkene radiator wire spread at whole precoat 13 like this, increased the heat radiating area of semiconductor refrigeration piece 2 greatly, make semiconductor refrigeration piece 2 can last the refrigeration. The fabric layer 13 is one of nylon cloth, canvas, leather/artificial leather, polycarbonate, PVC and polyurethane. In actual use, the oxford fabric in canvas is generally used as the fabric layer 13, because the oxford fabric has certain pores on the surface to facilitate heat exchange.
Specifically, the heat conductive reflection layer 11, the heat insulating filler layer 12 and the fabric layer 13 are sewn together by sewing. The plurality of semiconductor refrigeration pieces 2 are distributed on the fixing main body 1 in an array mode, and the total area of the whole material layer 13 is the area covered by the heat conducting piece 22. The heat insulation filling layer 12 is one or more of foam plastic, superfine glass wool, high silicon-oxygen wool and aerogel felt, and the aerogel felt is generally used in the heat insulation filling layer 12 in practice, so that the operability is high, the filling is convenient, and peculiar smell is not generated. The case is shaped into a box body or box body shape by a temperature control structure, and an opening is arranged through a zipper. It is worth mentioning that the temperature control structure for the luggage has certain flexibility and can be suitable for sewing by a sewing machine or hot-press shaping.
As shown in FIG. 4, when the thermal insulation packing material is applied to a lunch box/lunch box, the main body of the lunch box/lunch box is directly sewn by a temperature control structure for a case, and the inside of the thermal insulation packing material is food with larger load bearing, so that the thermal insulation packing layer 12 is filled with rigid foam plastics, and the fabric layer 13 can be made of polycarbonate, PVC, polyurethane and the like. It can be known from fig. 4 that the side pocket is disposed outside the fabric layer 13 to facilitate storage of the charger baby and quick connection with the USB input socket. On the back of the figure are several buttons with different functions, which are located in front of the controller of the semiconductor chilling plate 2.
As shown in fig. 5, when the cooling device is applied to a backpack/mommy bag/outdoor sports bag, a large space is required inside the backpack/mommy bag/outdoor sports bag when not holding articles, so that the semiconductor cooling plate 2 can conveniently cool or heat. In some backpack embodiments it may be that the heat conductive reflective layer 11 of the semiconductor chilling plate 2 faces the back of the user. It is worth mentioning that the side pocket or the front pocket is not disposed to prevent the heat dissipation of the semiconductor cooling sheet 2 where the side pocket or the front pocket is provided on the backpack/mommy bag/outdoor sports bag, but the heat-conducting member 22 is still extended to these positions to increase the heat dissipation area.
Application scenario 3
As shown in fig. 6, the bottle bag is applied to a bottle bag/mother and infant product bag, and the bottle bag adopts the semiconductor refrigeration sheet 2 with a very small model, so that the limitation caused by the arc arrangement of the temperature control structure for the bag is avoided, and the heat dissipation area is reasonably proportioned. Generally, the bag type adopts that the USB input socket is externally arranged and is led out from the controller by a wire. In some embodiments, a hook and loop fastener is also provided on the fabric layer 13 to attach the bag directly to the inside of the backpack.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
