Referring to fig. 1-5, the technical solution provided by the present invention is: a multifunctional circulating heat and cold exchange backpack comprises a backpack 1 and straps; the straps are respectively sewn with the back surface of the backpack into an integral structure.

The creation point of the application lies in: the system also comprises a circulating heat and cold exchange mechanism 2, wherein the circulating heat and cold exchange mechanism 2 comprises a micro radiating fan 21, a radiating fin 24, a crystal refrigerating fin 25, a water circulating exchanger 26, a micro circulating water pump 27 with a water pump water inlet and a water pump water outlet, a circulating water pipe 28 and a power supply 29; the circulating cold and heat exchange mechanism can circularly dissipate heat or preserve heat. Thereby solved present cooling knapsack cooling function singleness, can only realize cold circulation, can't realize thermal cycle or cold circulation switching function, and adopted the heat dissipation function simple behind the thermal cycle, lead to the heat to be difficult to radiating problem very fast. The circulating cold and heat exchange mechanism can keep warm or can also dissipate heat, is convenient to use in the cold or hot days, and increases the use flexibility.

The structure of the circulating heat exchange mechanism is as follows, as shown in fig. 3.

The miniature radiating fan 21 is screwed on the surface of the radiating fin, the radiating fin 24 and the crystal refrigerating sheet 25 are sequentially bonded after being thermally melted through the heat-conducting silica gel from outside to inside, the crystal refrigerating sheet 25 is bonded on the front surface of the water circulation exchanger 26, and the water circulation exchanger is a metal box body. Water is contained within the water circuit exchanger 26. Water cycle interchanger 26 intercommunication has inlet tube and outlet pipe, and seal installation has circulating pipe respectively on inlet tube and outlet pipe, and circulating pipe passes braces and the other end respectively seal installation at the water pump water inlet and the water pump delivery port that miniature circulating water pump 27 has, miniature circulating water pump 27, miniature radiator fan 21 and crystal refrigeration piece 25 are connected through the power cord electricity respectively to power 29, installs shift knob 30 on the power cord. The switch button is convenient to press to realize work.

The key points of the circulating cold and heat exchange mechanism are as follows: the crystal refrigeration piece is electrified, and then the back surface of the crystal refrigeration piece refrigerates the surface heat, and the heat is radiated by the bonded radiating fins. The back side of the crystal refrigerating sheet can refrigerate water in the water circulation exchanger, so that heat can be dissipated for the water inside the crystal refrigerating sheet, and the heat of the water in the water circulation exchanger is discharged from the outside.

The positive electrode and the negative electrode of a power supply electrically connected with the crystal refrigeration piece can be reversely connected, so that the cold inner side surface of the crystal refrigeration piece is hot, and the inside of the water circulation exchanger is heated and externally refrigerated due to the fact that the crystal refrigeration piece is stuck on the surface of the water circulation exchanger, and heating is facilitated. Therefore, the backpack is used for cold and hot dual purposes. This enables the hot or cold cycle switching function.

The working principle of the circulating cold and heat exchange mechanism is as follows: the power supply supplies electric energy, and the switch button is pressed to simultaneously start the crystal refrigeration sheets, the micro circulating water pump and the micro cooling fan which are connected in parallel for cooling. The crystal refrigeration piece is electrified and then the surface adhered to the water circulation exchanger is refrigerated, the temperature of the water circulation exchanger is reduced, the temperature of the internal water is also reduced, and the heat dissipation piece and the miniature heat dissipation fan dissipate heat to accelerate heat volatilization. On the contrary, the surface of the crystal refrigeration sheet, which is adhered to the water circulation exchanger after being electrified, heats, keeps the temperature of the water circulation exchanger, and keeps the temperature of the radiating fin and the miniature radiating fan after heat dissipation.

The first strap 11 and the second strap 12 are provided with through holes 13 for passing through circulating water pipes. As can be seen from the figure 1, the first and second braces are hollow, and the circulating water pipes respectively penetrate through the interiors of the first and second braces and are respectively and hermetically installed at the water pump water inlet and the water pump water outlet of the miniature water pump.

The circulating water pipe arrangement in the application is as shown in figure 1, because the circulating heat and cold exchange mechanism is placed inside the hidden bag, the circulating water pipe of the water circulating heat exchanger in the circulating heat and cold exchange mechanism in a sealing and sleeving mode respectively penetrates through the through holes formed in the first straps and the second straps and respectively penetrates through the through holes below the first straps and the second straps along the tracks of the first straps and the second straps, and then penetrates through the bottom surface of the hidden bag along the shape track of the bottom surface inside the backpack and is respectively sleeved on the water pump water inlet and the water pump water outlet communicated with the micro circulating water pump in a sealing and sleeving mode.

Further, the circulating heat exchange mechanism is applied to the backpack, and the creation point is that the circulating heat exchange mechanism and the structure thereof installed on the backpack can also be applied to other products.

In use, the external power supply of the power supply in the circulating cold and hot exchange mechanism arranged in the concealed bag provides electric energy, the switch button is pressed down, the crystal refrigerating sheets connected in parallel, the micro circulating water pump and the micro radiating fan are started to radiate heat at the same time, the circulating water pipe closest to the straps of the human body can accelerate the circulating radiation, the radiating time is shorter, and the effect is improved.
