Figure 2 The front view of the heat exchange plate and the heating element provided in the embodiment of the present application is shown. Figure 3 The schematic diagram of the structure of the heat exchange plate and the heating element provided in the embodiment of the present application is shown. Figure 4 A cross-sectional view of a water exchange tank provided in an embodiment of the present application is shown.

[0032] like Figures 1 to 4 As shown, an embodiment of the present application provides a water exchange tank, including a tank body 1 and a heating element 2, the tank body 1 is provided with an inner cavity, and the inner cavity of the tank body 1 is provided with a first heat exchange fluid; the inner side wall of the tank body 1 is provided with a heat exchange channel 11, the heat exchange channel 11 is used to flow a second heat exchange fluid, and the second heat exchange fluid is used to exchange heat with the first heat exchange fluid; the heating element 2 is arranged in the inner cavity of the tank body 1 and is used to heat the first heat exchange fluid in the inner cavity of the tank body 1.

[0033] It should be understood that the box body 1 is provided with a top wall, a bottom wall and a side wall, and the top wall, the bottom wall and the side wall of the box body 1 are detachably connected to facilitate the assembly of the box body 1, and the top wall, the bottom wall and the side wall are arranged to form an inner cavity of the box body 1. The inner cavity of the box body 1 is provided with a first heat exchange fluid, and the first heat exchange fluid can be a gas, a liquid or a gas-liquid mixed fluid, which is not limited in this application, and the box body 1 is sealed to prevent the first heat exchange fluid in the box body 1 from flowing out. In one example, the first heat exchange fluid is a liquid. The first heat exchange fluid is stationary in the inner cavity of the box body 1, that is, the first heat exchange fluid does not flow in the box body 1.

[0034] The heating element 2 is arranged in the inner cavity of the box body 1, and a connecting wire is arranged at one end of the heating element 2, and the connecting wire is used to connect the power supply to facilitate the operation of the heating element 2. The heating element 2 generates heat when working, so that the heating element 2 heats the first heat exchange fluid and increases the temperature of the first heat exchange fluid.

[0035] The side wall of the box body 1 is provided with a heat exchange channel 11, and a second heat exchange fluid is provided in the heat exchange channel 11. The second heat exchange fluid can be a gas, a liquid, or a gas-liquid mixed fluid, which is not limited in this application. In one example, the second heat exchange fluid is a liquid. The second heat exchange fluid flows in the heat exchange channel 11 so that the second heat exchange fluid exchanges heat with the first heat exchange fluid.

[0036] Since the heat exchange channel 11 is arranged on the side wall of the box body 1, it will not interfere with the heating element 2, and the volume of the box body 1 can be reduced. Compared with the heat exchange pipe, the arrangement of the heat exchange channel 11 of the present application can reduce the volume occupied by the heat exchange pipe, and can further reduce the thickness of the box body 1, thereby reducing the volume of the shower and improving user satisfaction. At the same time, the heat exchange channel 11 is arranged on the side wall of the box body 1, which can increase the contact area between the first heat exchange fluid and the heat exchange channel 11, thereby improving the heat exchange effect between the first heat exchange fluid and the second heat exchange fluid.

[0037] In some optional embodiments, a heat exchange plate 3 is further included. The heat exchange plate 3 is formed with a heat exchange groove. The heat exchange plate 3 is fitted to the inner wall of the box body 1 so that the heat exchange groove and the inner wall of the box body 1 form a heat exchange channel 11.

[0038] During preparation, the heat exchange plate 3 is pressed into a heat exchange groove through a mold, and the inner wall of the box body 1 is set as a plane. The side of the heat exchange plate 3 with the heat exchange groove is fitted and sealed to the inner wall of the box body 1, so that the heat exchange plate 3 and the inner wall of the box body 1 form a heat exchange channel 11.

[0039] In the present application, the heat exchange plate 3 is arranged in close contact with the inner wall of the box body 1, so that the bearing capacity of the heat exchange channel can be improved.

[0040] The present application does not limit the shape of the heat exchange groove, and the cross-section of the heat exchange groove can be arc-shaped or rectangular.

[0041] During heat exchange, the first heat exchange fluid exchanges heat with the heat exchange plate 3, thereby increasing the contact area between the first heat exchange fluid and the heat exchange channel 11, thereby improving the heat exchange effect between the first heat exchange fluid and the second heat exchange fluid.

[0042] In some optional embodiments, the inner wall of the box body 1 is a composite plate, and the composite plate is integrally formed with a heat exchange channel 11. The inner wall of the box body 1 is made of aluminum.

[0043] During the preparation, the first step is to provide a thick aluminum plate and a thin aluminum plate, anneal the thick aluminum plate and the thin aluminum plate, and then cool at room temperature; the second step is to roughen one side of the thick aluminum plate by a roughening machine so that the thick aluminum plate has a certain degree of roughness; the third step is to print graphite on the rough side of the thick aluminum plate by a screen printing machine, form a graphite layer and a graphite pipe on the surface of the thick aluminum plate, and then send it to a drying oven for drying; the fourth step is to cover the surface of the thick aluminum plate with a thin aluminum plate to form a double-layer aluminum plate, and then put it into a continuous furnace for heating; the fifth step is to hot-roll and roll the heated double-layer aluminum plate to form a composite aluminum plate, and cool it while hot-rolling and rolling; the sixth step is to anneal the composite aluminum plate, and after annealing Straighten it through a leveler, and then drill a process hole for blowing on the composite aluminum plate, the process hole is located on the graphite pipe; the seventh step, put the drilled composite aluminum plate into an inflation mold, and the mold is heated by an electric heating rod; the eighth step, introduce inflation gas through the process hole, and perform low-speed thermoplastic inflation molding on it, so that the aluminum plate on the graphite pipe bulges to form a heat exchange channel 11 on the composite aluminum plate, and after the molding is completed, take out the composite aluminum plate for cooling; the ninth step, cut the composite aluminum plate forming the heat exchange channel 11 to prepare it into a box body 1; the tenth step, perform necessary air tightness detection and surface treatment on the heat exchange channel 11 to obtain a finished product, and finally perform appearance inspection and packaging on the finished product.

[0044] When the inner wall of the box body 1 is a composite plate and the composite plate is integrally formed with the heat exchange channel 11, there is no need to weld the box body 1 and the heat exchange plate, so that the sealing effect of the heat exchange channel 11 is better, but the heat exchange channel 11 prepared by this method has poor pressure bearing capacity.

[0045] In some optional embodiments, the heating element 2 is disposed in the inner cavity of the box body 1 and close to the bottom wall of the box body 1, and the heating element 2 is bent toward the bottom wall of the box body 1 to form an extension section. The heating element 2 is located in the inner cavity of the box body 1 and in the lower part of the box body 1. Compared with the heating element 2 located in the upper part of the box body 1, the heating element 2 located in the lower part of the box body 1 heats the first heat exchange fluid more evenly and has a better heating effect.

[0046] The heating element 2 is bent toward the bottom wall of the box body 1 to form an extended section, thereby increasing the length of the heating element 2 and further improving the effect of heating the first heat exchange fluid.

[0047] Reference Figure 5-Figure 7 , Figure 5 A schematic diagram showing the structure of a heat exchange plate provided in an embodiment of the present application Figure 1 , Figure 6 A schematic diagram showing the structure of a heat exchange plate provided in an embodiment of the present application Figure 2 , Figure 7 The structure of a heat exchange plate provided in an embodiment of the present application is shown as follows: Figure 3 In some optional embodiments, the heat exchange channel 11 is arranged in a serpentine shape. The serpentine shape of the heat exchange channel 11 can further increase the time the second heat exchange fluid stays in the heat exchange channel 11, thereby improving the heat exchange effect between the first heat exchange fluid and the second heat exchange fluid.

[0048] In some optional embodiments, the heat exchange channel 11 is further provided with a connecting channel 12, and the connecting channel 12 extends along the height direction of the box body 1, so that two adjacent sections of the serpentine heat exchange channel 11 along the height direction of the box body 1 are connected. The provision of the connecting channel 12 can connect two adjacent sections of the heat exchange channel 11 along the height direction of the box body 1, providing multiple flow paths for the second heat exchange fluid, further improving the heat exchange effect between the first heat exchange fluid and the second heat exchange fluid.

[0049] In some optional embodiments, a buffer section 113 is provided at one end of the heat exchange channel 11 away from the bottom wall of the housing 1, so as to increase the time in the heat exchange channel 11. The provision of the buffer section 113 can increase the flow path of the second heat exchange fluid in the heat exchange channel 11, thereby increasing the flow time of the second heat exchange fluid in the heat exchange channel 11 and improving the heat exchange effect between the first heat exchange fluid and the second heat exchange fluid.

[0050] In some optional embodiments, the heat exchange channel 11 is connected to the inlet 111 and the outlet 112, and the inlet 111 and the outlet 112 are both arranged at one end of the housing 1 facing the bottom wall of the housing 1, and the second heat exchange fluid enters the heat exchange channel 11 through the inlet 111, and the second heat exchange fluid flows in the heat exchange channel 11 toward the bottom wall of the housing 1, and flows out from the outlet 112. The heat exchange channel 11 is provided with an inlet 111, and the fluid flows in from the inlet 111, and the heat exchange channel 11 is provided with an outlet 112, and the fluid after passing through the heat exchange channel 11 flows out from the outlet. The inlet 111 and the outlet 112 are both arranged at one end of the housing 1, so as to facilitate the connection of external pipelines.

[0051] During operation, the second heat exchange fluid flows in from the inlet 111, then moves upward, and after a certain distance, flows downward again, and finally flows out through the outlet 112. The present application restricts the flow direction of the second heat exchange fluid, which can further improve the heat exchange effect between the first heat exchange fluid and the second heat exchange fluid.

[0052] Reference Figure 2 and Figure 3 In some optional embodiments, the bottom wall of the box body 1 is provided with an inlet pipe 13 and an outlet pipe 14, and the height of the outlet pipe 14 is higher than that of the inlet pipe 13. This makes it easier to pour the first heat exchange fluid into the box body 1, while also reducing the probability of the first heat exchange fluid flowing out of the box body 1.

[0053] In some optional embodiments, the present application also includes a shower, and the shower includes any of the above-mentioned water exchange tanks. The water exchange tank includes a box body 1 and a heating element 2, the box body 1 is provided with an inner cavity, and the inner cavity of the box body 1 is provided with a first heat exchange fluid; the inner side wall of the box body 1 is provided with a heat exchange channel 11, and the heat exchange channel 11 is used to flow a second heat exchange fluid, and the second heat exchange fluid is used to exchange heat with the first heat exchange fluid; the heating element 2 is provided in the inner cavity of the box body 1 and is used to heat the first heat exchange fluid in the inner cavity of the box body 1. Since the heat exchange channel 11 is provided on the side wall of the box body 1, it will not interfere with the heating element 2, and the volume of the box body 1 can be reduced. Compared with the heat exchange pipe, the setting of the heat exchange channel 11 of the present application can reduce the volume occupied by the heat exchange pipe, and can further reduce the thickness of the box body 1, thereby reducing the volume of the shower and improving user satisfaction.
