[0029] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings.
[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The accompanying drawings show preferred embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.
[0031] Unless otherwise specified, all raw materials, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.
[0032] Figure 1 This is a schematic diagram of the structure of a liquid-cooled pressure oven provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the main body 1 of the oven. Figure 3 This is a structural diagram of the oven body 1 after the safety shielding door 15 has been removed. Figure 4 This is a perspective structural diagram of box 11, see reference. Figure 1-4 As shown, the liquid-cooled pressure oven includes an oven body 1, a liquid-cooled circulation assembly 2, and a pressure control assembly 3; the liquid-cooled circulation assembly 2 and the pressure control assembly 3 are respectively disposed on the outside of the oven body 1, and the liquid-cooled circulation assembly 2 and the pressure control assembly 3 are respectively connected to the oven body 1; the oven body 1 is used to realize the heating function, the liquid-cooled circulation assembly 2 is used to exchange heat and cool the oven body 1, and the pressure control assembly 3 is used to control the pressure inside the oven body 1;
[0033] The oven body 1 includes a hollow box 11. The inner wall 110 of the box 11 forms a heating cavity 111. A heating rack 16 is provided in the heating cavity 111. The heating cavity 111 is provided with an air inlet 114 and an exhaust outlet 113. The pressure control component 3 is connected to the air inlet 114 and the exhaust outlet 113. A flow channel cavity 112 is hollowed out between the inner wall 110 and the outer wall 119 of the box 11. The flow channel cavity 112 is provided with a liquid inlet 115 and a liquid outlet 116. The liquid cooling circulation component 2 is connected to the liquid inlet 115 and the liquid outlet 116.
[0034] The box 11 has a side opening, and a support frame 13 is provided on the outer side of the side opening. A rotating hinge 14 is provided on the support frame 13, and a safety shielding door 15 is hinged to the rotating hinge 14. The safety shielding door 15 is fastened to the side opening of the box 11, thereby forming a stable internal sealed environment.
[0035] In this embodiment of the utility model, the liquid inlet 115 is located at the upper end of the housing 11, and the liquid outlet 116 is located at the lower end of the housing 11. This allows the cooling medium to flow naturally down the circulation channel to the liquid outlet 116 under the action of gravity, effectively reducing additional energy consumption.
[0036] Multiple flow channel plates 117 are staggered within the flow channel cavity 112, forming liquid-cooled flow channels 118 between adjacent flow channel plates 117. The liquid-cooled circulation assembly 2 inputs cooling medium (such as cooling water) into the flow channel cavity 112 through the liquid inlet 115. The cooling medium passes through each flow channel sequentially under the separation of the flow channel plates 117 and reaches the liquid outlet 116 for discharge, carrying away the heat transferred from the heating cavity 111, thereby achieving cooling of the oven body 1. The arrangement of the flow channel plates 117 increases the transmission path length of the cooling medium and improves the cooling effect.
[0037] The housing 11 is also connected to a pressure display external pipe 4, which can be used to connect a pressure display component to facilitate real-time monitoring of the pressure status inside the housing 11.
[0038] In this embodiment of the utility model, a plurality of support frames 17 are provided at the bottom of the box 11, and the support frames 17 are used to provide physical support for the box 11; the support frames 17 are screwed or welded to the box 11.
[0039] In this embodiment of the present invention, a heating device (not shown) is also provided in the heating cavity 111. The heating device is electrically connected to an external electrical control box to provide a heating function. The heating device may be, for example, a conventional heating plate or heating element or other electric heating component. The external electrical control box controls the opening, closing and power of the heating device.
[0040] Figure 5 This is a schematic diagram of the liquid cooling circulation component 2, combined with... Figure 5As shown, the liquid cooling circulation assembly 2 includes a liquid cooling circulation motor 12, a cooling liquid inlet pipe 21, a cooling liquid outlet pipe 22, and a circulation outlet pipe 24.

The cooling liquid outlet pipe 22 is connected to the inlet pipe 115, and the circulation outlet pipe 24 is connected to the outlet pipe 116. The external cooling medium is sent into the liquid cooling circulation motor 12 through the cooling liquid inlet pipe 21. The liquid cooling circulation motor 12 outputs power to send the cooling medium from the cooling liquid outlet pipe 22 into the inlet pipe 115 and into the flow channel cavity 112, and finally discharged from the outlet pipe 116 and the cooling liquid outlet pipe 22.
[0041] In other embodiments of this utility model, the cooling liquid inlet pipe 21 is connected to the cooling liquid outlet pipe 22, and the cooling liquid inlet pipe 21 is provided with a liquid inlet solenoid valve 23. The liquid inlet solenoid valve 23 is used to control the transmission state of the cooling medium in the cooling liquid inlet pipe 21, including opening and closing. When necessary (e.g., equipment maintenance, disassembly, etc.), the cooling medium transmitted by the cooling liquid inlet pipe 21 can also be directly discharged from the cooling liquid outlet pipe 22 under the control of the liquid inlet solenoid valve 23.
[0042] In this embodiment of the present invention, a pressure gauge 25 is further provided on the cooling liquid inlet pipe 21 or the cooling liquid outlet pipe 22 to detect the pressure state of the cooling medium in the cooling liquid inlet pipe 21.

Figure 6 As shown, the pressure control component 3 includes an air intake pipe 31, a filter valve 32, a booster pump 33, and an air outlet pipe 34. The air intake pipe 31 is connected to the air inlet 114, and an air intake control valve 35 is provided at the connection between the air intake pipe 31 and the air inlet 114. The air intake control valve 35 is used to control the amount of air entering the air inlet 114. The filter valve 32 and the booster pump 33 are sequentially arranged on the air intake pipe 31. The filter valve 32 is used to control the amount of air entering the air intake pipe 31 and also provides impurity filtration. The booster pump 33 is used to pressurize the air entering the pipe.
[0044] The intake control valve 35 is also connected to a pressure regulating line 36, and a proportional pressure control valve 38 is provided on the pressure regulating line 36. The proportional pressure control valve 38 is connected to the heating chamber 111 and is used to regulate the pressure in the heating chamber 111.
[0045] The pressure regulating pipeline 36 is also equipped with a silencer 37 to reduce noise during pressure regulation.
