[0032] The following is combined with Figures 1 to 7 The present invention is described in further detail, but is not intended to limit the present invention.

[0033] like Figure 1 and 2 As shown, in one embodiment of the present invention, the gas heat exchange device includes a shell 100, at least one constant temperature energy storage component 200 and at least two wind direction plates 300; all the wind direction plates 200 are connected side by side to the inner wall of the shell 100; and a curved heat exchange channel 400 is provided between all the wind direction plates 200 and the inner wall of the shell 100; an inlet component 110 and an output component 120 are provided on the shell 100; the inlet component 110 and the output component 120 are respectively connected to the two ends of the heat exchange channel 400; one end of the constant temperature energy storage component 200 is connected to the shell 100, and the other end of the constant temperature energy storage component 200 is respectively provided through the thickness direction of the wind direction plate 300 and the heat exchange channel 400.

[0034] The technical solution of the present invention adopts the introduction component to introduce gas, so that the introduced gas passes through the constant temperature energy storage component and then is transported in a curved flow along the path direction of the heat exchange channel, thereby realizing multi-point heat exchange operation along the curved direction to form an airflow with a more uniform temperature, which is beneficial to ensuring the drying quality of the material in the drying box; therefore, it is beneficial to the efficiency of the drying operation.

[0035] Specifically, in some embodiments, Figure 1 and 2As shown in Figure 3, the inlet component 110 is an inlet pipe; the inlet pipe is connected to the top of the housing 100; an input channel 111 is provided in the inlet pipe; the input end of the input channel 111 is connected to the outside of the housing 100; the output end of the input channel 111 is connected to one end of the heat exchange channel 400; the output component 120 includes a gas pressurizing component 121 and an output pipe 122; the output pipe 122 is connected to the bottom of the side end of the housing 100; the gas pressurizing component 121 is connected to the interior of the housing 100, and the input end of the gas pressurizing component 121 is connected to the other end of the heat exchange channel 400; the output end of the gas pressurizing component 121 is connected to the input end of the output pipe 122. The gas pressurizing component 121 is a fan or an air pump. That is to say, by transporting and introducing from the inlet pipe at the top, and the curved heat exchange operation of the middle heat exchange channel 400, combined with the discharge function of the gas booster component 121 at the upper inner bottom, the synergistic transport effect of gravity can be utilized to reduce the input of power sources, and the speed and efficiency of heat exchange discharge can also be ensured.

[0036] Specifically, in some embodiments, Figure 2 and 3 As shown, the heat exchange channel 400 includes a first heat exchange bend section 410, a second heat exchange bend section 420, and a third heat exchange bend section 430, which are sequentially connected. A curved structure is formed between the first heat exchange bend section 410, the second heat exchange bend section 420, and the third heat exchange bend section 430. The first heat exchange bend section 410, the second heat exchange bend section 420, and the third heat exchange bend section 430 are respectively arranged at an angle (preferably perpendicularly) to the constant temperature energy storage component 200. In some embodiments, one end of the constant temperature energy storage component 200 passes through the first heat exchange bend section 410, the second heat exchange bend section 420, and the third heat exchange bend section 430 and is connected to the wind direction plate 300. That is, the structure is arranged by passing one end of the constant temperature energy storage component 200 through the first heat exchange bending section 410, the second heat exchange bending section 420 and the third heat exchange bending section 430 to ensure the orderliness of the gas flow and the uniformity of the heat exchange formed by the gas passing through and contacting the constant temperature energy storage component 200.

[0037] Specifically, in some embodiments, Figure 3 As shown, the first heat exchange bending section 410 includes a first vertical section 411 and a first horizontal section 412 which are connected to each other in sequence; one end of the first vertical section 411 is connected to the inlet component 110; the first horizontal section 412 is bent toward the second heat exchange bending section 420 away from one end of the first vertical section 411; this structure forms an L-shaped structure through the first vertical section 411 and the first horizontal section 412, which can realize the operation of changing the direction of the gas undergoing preliminary heat exchange, which is conducive to forming a gas with uniform heat exchange.

[0038] Specifically, in some embodiments, Figure 3 As shown, the second heat exchange bending section 420 includes a second vertical section 421 and a second horizontal section 422, which are sequentially connected to each other. One end of the second vertical section 421 is connected to the first heat exchange bending section 410 (the first horizontal section 412). The other end of the second vertical section 421 is bent toward the input end of the first heat exchange bending section 410 (the first vertical section 411). The end of the second horizontal section 422, which is remote from the second vertical section 421, is connected to the third heat exchange bending section 430. This structure, formed by the second vertical section 421 and the second horizontal section 422, forms an inverted L-shaped structure, which can achieve the operation of changing the direction of gas after the second heat exchange, and promotes the formation of uniform heat exchange gas.

[0039] Specifically, in some embodiments, Figure 3 As shown, the third heat exchange bending section 430 includes a third vertical section 431, a third horizontal section 432, and a fourth vertical section 433. One end of the third vertical section 431 is connected to the second heat exchange bending section 420 (the second horizontal section 422). The other end of the third vertical section 431 is bent in the direction of the diameter of the input end of the second heat exchange bending section 420 (the second vertical section 421). The end of the third horizontal section 432, which is remote from the third vertical section 431, is connected to the bottom of the fourth vertical section 433. The end of the fourth vertical section 433, which is remote from the third horizontal section 432, is bent toward the output component 120 and connected to the input end of the output component 120. This structure, formed by the third vertical section 431, the third horizontal section 432, and the fourth vertical section 433, forms a U-shaped structure, which can achieve directional transmission of the gas undergoing further heat exchange, thereby facilitating uniform heat exchange.

[0040] Specifically, in some embodiments, Figure 3 As shown, the relationship between the width d1 of the first vertical segment 411, the width d2 of the second vertical segment 421, the width d3 of the third vertical segment 431, and the width d4 of the fourth vertical segment 433 (not shown) satisfies the following: d1 = d2 = d3 = d4. This structure utilizes multiple curved heat exchange channels 400 of equal width to achieve uniform heat exchange time and speed, thereby facilitating uniform heat exchange.

[0041] Specifically, in some embodiments, Figure 3As shown, the relationship between the height h1 of the first horizontal segment 412, the height h2 of the second horizontal segment 422, the height h3 of the third horizontal segment 432, and the height h4 of the fourth vertical segment 433 satisfies: h1 = h2 = h3 = (1 / 3 to 1 / 2) h4; preferably: h1 = h2 = h3 = 1 / 2 * h4. This structure achieves uniform heat exchange time and speed by using multiple curved heat exchange channels 400 with the same bending height, thereby facilitating uniform heat exchange.

[0042] Specifically, in some embodiments, Figure 3 As shown, the relationship between the height h1 of the first horizontal section 412, the height h2 of the second horizontal section 422, the height h3 of the third horizontal section 432, and the height h0 of the inner diameter of the housing 100 satisfies: h1 = h2 = h3 = (1 / 4 to 1 / 3) * h0. Preferably, h1 = h2 = h3 = 1 / 3 * h0. This structure reserves a smaller bent outlet to increase the air pressure there, thereby increasing the delivery speed and further improving heat exchange efficiency.

[0043] Specifically, in some embodiments, Figure 3 and 4 As shown, the wind deflector 300 is provided with at least two first mounting holes 310 and at least two second mounting holes 320; the first mounting holes 310 and the second mounting holes 320 are staggered along the height direction of the wind deflector 300; and the projection of the first mounting hole 310 toward the second mounting hole 320 is offset or partially overlapped with the second mounting hole 320; the interiors of the first mounting holes 310 and the second mounting holes 320 are both connected to the corresponding constant temperature energy storage components 200. In other words, the first mounting holes 310 are arranged in an array with equal spacing in the same horizontal plane direction, and the second mounting holes 320 are arranged in an array with equal spacing in the same horizontal plane direction, and the second mounting holes 320 are arranged between two adjacent first mounting holes 310, so that the constant temperature energy storage components 200 in different horizontal plane directions are offset or partially overlapped, thereby promoting the gas to pass through the surface of the constant temperature energy storage component 200 for heat exchange and then be diverted along its two side ends, thereby ensuring smooth and orderly transportation.

[0044] Specifically, in some embodiments, Figure 1 and 2As shown in FIG3 , the wind deflector 300 includes a first plate 301, a second plate 302, and a third plate 303; the first plate 301, the second plate 302, and the third plate 303 are sequentially arranged side by side on the inner wall of the shell 100; the first plate 301 and the third plate 303 are connected to the inner top of the shell 100; the second plate 302 is connected to the inner bottom of the shell 100; and the heat exchange channel 400 is formed between the first plate 301, the second plate 302, and the third plate 303 and the inner wall of the shell 100. In the following embodiment, as Figure 3 As shown, a first heat exchange bending section 410 is formed between the first plate 301 and the inner wall of the shell 100; a second heat exchange bending section 420 is formed between the first plate 301, the second plate 302 and the inner wall of the shell 100; and a third heat exchange bending section 430 is formed between the second plate 302, the third plate 303 and the inner wall of the shell 100. This structure forms a serpentine heat exchange channel 400 by staggering the wind deflectors 300 up and down; thereby achieving multi-point heat exchange operations along the curved direction to form an airflow with a more uniform temperature, which is beneficial to ensuring the drying quality of the material in the drying box; therefore, it is beneficial to the efficiency of the drying operation. Further, in some embodiments, such as Figure 3 As shown, the housing 100 includes a bottom shell 101 and a cover plate 102 connected to the opening of the bottom shell 101; a second plate 302 connected to the inner bottom of the bottom shell 101; a first plate 301 and a third plate 303 connected to the inner bottom of the cover plate 102; an inlet component 110 disposed on the cover plate 102; a constant temperature energy storage component 200 disposed at the inner end of the bottom shell 101; and an output component 120 disposed at the inner bottom of the bottom shell 101. Furthermore, an insulating filler material is provided between the second plate 302 and the inner wall of the housing 100 to provide a certain degree of insulation to prevent burns to outsiders and effectively guide heat to the output component 120. The insulating filler material is selected from polyurethane rigid foam or asbestos.

[0045] Specifically, in some embodiments, Figure 3 and 5 As shown, the constant temperature energy storage component 200 includes a constant temperature tube 210 and a heat generating element 220; the constant temperature tube 210 passes through the heat exchange channel 400 and is connected to the wind deflector 300 (the inner wall of the first mounting hole 310 or the second mounting hole 320); an energy storage cavity 211 is provided in the constant temperature tube 210; the mounting end of the heat generating element 220 is connected to one side end of the constant temperature tube 210; the heat generating end of the heat generating element 220 is arranged inside the energy storage cavity 211. This structure generates heat through the heat generating element 220 and transfers it to the tube wall of the constant temperature tube 210. When the transported gas passes through the tube wall, a rapid heat exchange operation is performed, thereby forming an airflow with a more uniform temperature, which is beneficial to ensuring the drying quality of the material in the drying box; therefore, it is beneficial to the efficiency of the drying operation. Wherein, in some embodiments, such as Figure 5and 6 As shown, the thermostat tube 210 includes a heat-conducting side body 212 and a plug body 213 connected to the opening at the side end of the heat-conducting side body 212. The mounting end of the heat-generating element 220 is connected to the plug body 213. The heat-generating end of the heat-generating element 220 is located inside the heat-conducting side body 212. The outer surface of the heat-conducting side body 212 is connected to the wind deflector 300 (the inner wall of the first mounting hole 310 or the second mounting hole 320), ensuring assembly stability and smooth heat generation and transfer. Furthermore, the thermostat tube 210 is made of a metal tube, preferably stainless steel, to ensure rapid and uniform heat transfer.

[0046] Specifically, in some embodiments, Figure 5 、 6 As shown in Figure 7 , the heat generating element 220 includes a heat generating arc segment 222 and a first heat generating straight segment 221 and a second heat generating straight segment 223 connected to either side of the heat generating arc segment 222. Positioning posts 224 are provided on both the end of the first heat generating straight segment 221 away from the heat generating arc segment 222 and the end of the second heat generating straight segment 223 away from the heat generating arc segment 222. Positioning posts 224 are connected to the thermostatic tube 210 (plug 213). In other words, the heat generating arc segment 222 and the first heat generating straight segment 221 and the second heat generating straight segment 223 form a U-shaped heat pipe structure to heat the energy storage cavity 211, thereby achieving uniform and stable heat transfer to the thermostatic tube 210, thereby ensuring assembly stability and smooth heat generation and transfer.

[0047] Specifically, in some embodiments, Figure 6 and 7 As shown, the outer surface of the heat-generating element 220 is provided with at least one heat-dissipating protrusion 226; a mounting gap 225 is defined between the heat-dissipating protrusion 226 and the thermostatic tube 210. The heat-dissipating protrusions 226 are arranged in an equidistant array on the heat-generating arc segment 222, the first heat-generating straight segment 221, and the second heat-generating straight segment 223. Each side of the heat-dissipating protrusion 226 is provided with at least one heat-dissipating hole, each extending through the thickness of the heat-dissipating protrusion 226. The orthographic projections (top-to-bottom projections) of the heat-dissipating protrusions 226 on the first heat-generating straight segment 221 and the second heat-generating straight segment 223 are staggered. This means that heat is transferred to the thermostatic tube 210 through contact, preventing uneven local heating within the thermostatic tube 210. Furthermore, the heat-dissipating protrusions 226 and their heat-dissipating holes provide partial heat dissipation, preventing overheating of the heat-generating element 220 and affecting its power output, thereby ensuring uniform heating within the heat-generating element 220.

[0048] Specifically, in some embodiments, Figure 5As shown, the thermostatic tube 210 is provided with a pressure relief component 230, and both ends of the pressure relief component 230 are connected to the energy storage cavity 211 and the outside of the thermostatic tube 210; so as to achieve a pressure-free environment as much as possible inside the thermostatic tube 210, thereby ensuring the stability of use and the uniformity of heat generation. Figure 6 and 7 As shown, the pressure relief component 230 includes a first pressure relief hole 231 and a second pressure relief hole 232; the first pressure relief hole 231 is set to pass through the thickness of the plug body 213; the second pressure relief hole 232 is set to pass through the side end surface of the constant temperature tube 210; to overcome the defect of local temperature unevenness caused by the pressure relief holes on the circumferential surface of the constant temperature tube 210; and thus ensure the uniformity of heat generation.
