[0044] Reference Figures 1 to 6 As shown, this embodiment provides an inflatable cabinet, which includes an air box 100 and a first air-conducting heat dissipation pipe 200. Among them, at least one air hole group (not shown) is provided on the air box 100, and the air hole group includes two air holes arranged at intervals along the height direction of the air box 100; the first air-conducting heat dissipation pipe 200 is arranged in a one-to-one correspondence with the air hole group, and the first air-conducting heat dissipation pipe 200 is arranged inside the air box 100 or outside the air box 100, and the two ends of the first air-conducting heat dissipation pipe 200 are connected and arranged in a one-to-one correspondence with the two air holes of the corresponding air hole group.

[0045] When the first heat-conducting pipe 200 is arranged in the air box 100, the two ends of the first heat-conducting pipe 200 are connected to the two vents of the corresponding air hole group in a one-to-one correspondence, and the air outside the air box 100 can take away the heat inside the air box 100 by passing through the first heat-conducting pipe 200, thereby improving the heat dissipation of the inflatable cabinet and effectively preventing the heat concentration inside the inflatable cabinet. Among them, the two vents of the same air hole group are arranged at intervals along the height direction of the air box 100, so that the air can flow from bottom to top along the first heat-conducting pipe 200.

[0046] When the first heat-conducting pipe 200 is arranged outside the air box 100, due to the height difference between the two vents of the same air hole group and the heat of the gas at the top of the air box 100 is greater than the heat of the gas at the bottom, the first heat-conducting pipe 200 can realize rapid heat convection and exchange between the gas at the top of the air box 100 and the gas at the bottom, and the heat inside the air box 100 quickly diffuses, and the gas in the first heat-conducting pipe 200 can also exchange heat with the air outside the air box 100, thereby achieving the purpose of heat dissipation, effectively preventing heat concentration in the inflatable cabinet, and improving the heat dissipation of the inflatable cabinet.

[0047] In this embodiment, continue to refer to Figures 1 to 6As shown, the first air-conducting heat dissipation pipe 200 includes a first pipe body 211, a first corrugated pipe body 212 and a first sealing joint 213, wherein the first pipe body 211 is provided with the first corrugated pipe body 212 at both ends, the first corrugated pipe body 212 is connected with the first sealing joint 213, the first sealing joint 213 is connected to the air box 100, and the first sealing joint 213 is connected to the corresponding vent hole. In this embodiment, the air box 100 and the first pipe body 211 expand and contract with heat. By providing the first corrugated pipe body 212 at both ends of the first pipe body 211, the physical deformation of the air box 100 and the first pipe body 211 can be compensated, and a shock-absorbing effect is achieved. In addition, the design of the first sealing joint 213 facilitates the connection of the first air-conducting heat dissipation pipe 200 with the air box 100.

[0050] Exemplarily, the first bellows body 212 includes components such as a metal bellows, a bellows expansion joint, and a bellows heat exchange tube, and the specific structure thereof is prior art and will not be described in detail in this application.

[0051] Exemplarily, a first sealing member (not shown) is provided between the first sealing joint 213 and the air box 100 to ensure the sealing between the first sealing joint 213 and the air box 100 and prevent the air box 100 from leaking at the first sealing joint 213 .

[0052] Specifically, Figure 3 As shown, the first sealing joint 213 can be set as a flange, and the end of the flange is provided with an annular groove 2131, and the first sealing member is arranged in the annular groove 2131, so as to facilitate the positioning and assembly of the first sealing member.

[0054] In a feasible embodiment, the air hole group includes a first air hole group (not shown), the first air hole group includes a first air hole provided on the top plate 110 and a second air hole provided on the bottom plate 120, the first through hole and the second through hole are connected through the corresponding first heat conduction pipe 200, that is, the first end of the corresponding first heat conduction pipe 200 is connected to the first air hole, and the second end of the corresponding first heat conduction pipe 200 is connected to the second air hole, and the corresponding first heat conduction pipe 200 is provided in the air box 100. The air outside the air box 100 flows through the first heat conduction pipe 200 to take away the heat between the top plate 110 and the bottom plate 120 in the air box 100, so as to prevent the occurrence of heat concentration in the local area between the top plate 110 and the bottom plate 120, and reduce the temperature in the area between the top plate 110 and the bottom plate 120.

[0055] Exemplarily, the top plate 110 and the bottom plate 120 may be arranged in parallel or at an angle, which is not limited in the present application.

[0056] Exemplarily, at least one first pore group is provided. Exemplarily, a plurality of first pore groups may be arranged in a matrix.

[0057] For example, the first vent hole and the second vent hole of the same first vent hole group are coaxially arranged, that is, the first tube body 211 can be arranged as a straight tube, and the air flows through the first air-conducting heat dissipation tube 200 with small resistance and fast flow rate, which can take away more heat in the air box 100. Of course, the first vent hole and the second vent hole of the same first vent hole group can also be staggered, that is, the first tube body 211 is arranged at an angle with the height direction of the air box 100, and the first tube body 211 can be lengthened to increase the heat exchange area to achieve a good heat dissipation effect.

[0058] In this embodiment, refer to Figures 4 to 6 As shown, the top plate 110 may include a first plate portion 111 , a side plate 112 , and a second plate portion 113 connected in sequence, and the second plate portion 113 is disposed between the first plate portion 111 and the bottom plate 120 along the height direction of the air box 100 .

[0059] Exemplarily, the side plate 112 may be parallel to the height direction of the air box 100, and the first plate portion 111 and the second plate portion 113 may be perpendicular to the height direction of the air box 100. It can be understood that the air box 100 can be divided into three areas, namely the first area 101, the second area 102 and the third area 103, wherein the first area 101, the second area 102 and the third area 103 are connected in sequence, the first area 101 and the second area 102 are located between the first plate portion 111 and the bottom plate 120 and are separated by the second plate portion 113, and the third area 103 is located between the second plate portion 113 and the bottom plate 120 and is separated by the side plate 112.

[0060] Exemplarily, in order to improve the heat dissipation effect of the third area 103, the first air vent can be arranged on the second plate portion 113, that is, the first air conduction heat dissipation pipe 200 connecting the first air vent and the second air vent is arranged in the third area 103, and the first air conduction heat dissipation pipe 200 connecting the first air vent and the second air vent exchanges heat with the third area 103, thereby accelerating the heat dissipation and reducing the temperature of the third area 103.

It can be understood that the first heat-conducting pipe 200 connecting the third vent hole and the fourth vent hole connects the first area 101 and the third area 103 of the air box 100. Since the heat of the air box 100 is relatively concentrated in the first area 101 and the heat of the third area 103 is relatively small, the temperature difference between the first area 101 and the third area 103 is relatively large. The first heat conduction pipe 200 connecting the third air hole and the fourth air hole can realize rapid heat convection and exchange between the gas in the first area 101 and the gas in the third area 103, balance the temperature difference in the air box 100, and prevent heat concentration.

[0062] Exemplarily, the first tube body 211 of the first air-conducting heat dissipation tube 200 communicating with the third air holes and the fourth air holes of the same second air hole group is configured as an L-shaped tube, which is suitable for the circulation of gas.

It can be understood that the first conduit heat dissipation tube 200 connecting the fifth air hole and the sixth air hole is arranged in the first area 101 of the air box 100, and the air flowing through the first conduit heat dissipation tube 200 can take away the heat in the first area 101, accelerate the heat dissipation, and reduce the temperature in the first area 101.

[0065] Exemplarily, the first tube body 211 of the first air-conducting heat dissipation tube 200 communicating with the fifth air hole and the sixth air hole of the same third air hole group is configured as an L-shaped tube, which is suitable for the circulation of gas.

[0066] Exemplarily, at least one third air hole group is provided. Exemplarily, a plurality of third air hole groups may be arranged in a row.

[0067] In this embodiment, the inflatable cabinet may also include a fan (not shown), and the air outlet of the fan may be connected to the lower one of the two air holes in the air hole group, such as the second air hole and the sixth air hole, to accelerate the air flow in the corresponding first air guide heat dissipation pipe 200, reduce the temperature of the first air guide heat dissipation pipe 200, and improve the heat dissipation of the inflatable cabinet.

In this embodiment, a plurality of air boxes 100 can be arranged side by side, and the air circulation of the two adjacent air boxes 100 toward each other is poor, which affects the heat dissipation. In particular, the heat dissipation effect of the air box 100 located in the middle area is obviously inferior to that of the outermost air box 100. Through the arrangement of the second flow-conducting heat dissipation pipe 300, heat exchange between air boxes 100 and air boxes 100 can be achieved, and the gas in the second flow-conducting heat dissipation pipe 300 can also exchange heat with the air outside the air box 100, thereby improving the heat dissipation of the inflatable cabinet.

[0069] Exemplarily, a second air-conducting heat-dissipating pipe 300 may also be disposed between two non-adjacent air boxes 100 , that is, the second air-conducting heat-dissipating pipe 300 connects the two non-adjacent air boxes 100 .
