Description

Technical Field

[0001] This utility model relates to the field of vacuum furnace cooling technology, and in particular to a water-cooling device for a vacuum furnace. Background Technology

[0002] A vacuum furnace is a device that performs high-temperature processing in a vacuum environment. It is commonly used for high-temperature processes such as high-temperature sintering, annealing, heat treatment, and evaporation. Its main feature is that it can perform heating processes in the absence of oxygen and other gases. In order to ensure the normal operation of the vacuum furnace and prevent the equipment from being damaged by excessive temperature, a water cooling device is required for heat dissipation.

[0003] When using existing water-cooling devices to cool vacuum furnaces, the inventors have gradually discovered in practical applications that existing water-cooling devices cannot uniformly remove heat from the vacuum furnace and cannot perform circulating cooling. Therefore, we propose a water-cooling device for vacuum furnaces. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a water cooling device for a vacuum furnace, so as to solve the technical problem that the current water cooling device cannot uniformly remove the heat from the vacuum furnace and cannot perform circulating cooling.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A water-cooling device for a vacuum furnace includes a vacuum furnace, wherein a water-cooling channel is installed on the outer surface of the vacuum furnace, and two fixing plates are fixedly installed on the outer surface of the vacuum furnace, the two fixing plates being arranged symmetrically.

[0008] A cooling water circulator is fixedly installed on one of the fixed plates. The inlet of the cooling water circulator is connected to the water cooling channel, and the outlet of the cooling water circulator is connected to the water cooling channel through a water supply pressurization mechanism.

[0009] As an improved technical solution, the water-cooling channel includes a cooling pipe, which is wound around the outer surface of the vacuum furnace. A diversion pipe is connected to the cooling pipe, and a water inlet pipe is connected to the water inlet of the cooling pipe. The water inlet pipe is connected to the water supply and pressurization mechanism, and a drain pipe is connected to the drain outlet of the cooling pipe. The end of the drain pipe away from the cooling pipe is connected to the liquid inlet of the cooling water circulator.

[0010] As an improved technical solution, the cooling pipe is spirally wound around the outer surface of the vacuum furnace.

[0011] As an improved technical solution, the water supply pressurization mechanism includes a water pump, which is mounted on another fixed plate. A storage tank is installed on the outer surface of the vacuum furnace. An inlet pipe is provided between the storage tank and the water pump. The drain port of the storage tank is connected to the inlet of the water pump through the inlet pipe, and the drain port of the water pump is connected to the inlet pipe.

[0012] As an improved technical solution, a drain pipe is provided between the storage tank and the cooling water circulator, and the inlet of the storage tank is connected to the outlet of the cooling water circulator through the drain pipe.

[0013] As an improved technical solution, a water injection pipe is installed on the top of the storage box, and the water injection pipe is connected to the storage box.

[0014] As an improved technical solution, the drain pipe and the inlet pipe are symmetrically arranged along the central axis of the storage tank.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, by starting the water pump, the water pump draws cooling water from the storage tank into the pump through the inner cavity of the inlet pipe, and then discharges it through the output end of the pump. The water is then discharged into the cooling water circulation machine through the inner cavity of the inlet pipe, the inner cavity of the cooling pipe, the inner cavity of the distributor pipe, and the inner cavity of the drain pipe. During this period, the cooling water carries away the heat from the vacuum furnace evenly through the principle of heat exchange, thereby achieving the effect of heat dissipation from the vacuum furnace. This allows the heat from the vacuum furnace to be carried away evenly, thus facilitating heat dissipation from the vacuum furnace.

[0017] 2. In this utility model, by starting the cooling water circulator, the cooling water circulator discharges the cooled water through the inner cavity of the drain pipe into the storage tank for heat dissipation of the vacuum furnace. At the same time, the water pump repeats the above steps to complete the circulating cooling of the vacuum furnace until the temperature of the vacuum furnace is cooled to the specified temperature, thus facilitating the circulating cooling of the vacuum furnace.

The water cooling device for a vacuum furnace includes a vacuum furnace 1, a water cooling channel 2 installed on the outer surface of the vacuum furnace 1, and two fixing plates 3 fixedly installed on the outer surface of the vacuum furnace 1. The two fixing plates 3 are arranged symmetrically.

[0029] A cooling water circulator 4 is fixedly installed on a fixed plate 3. The model of the cooling water circulator 4 is AS-800, which is existing technology and will not be described in detail here. The liquid inlet of the cooling water circulator 4 is connected to the water cooling channel 2, and the liquid outlet of the cooling water circulator 4 is connected to the water cooling channel 2 through a water supply pressurization mechanism.

[0030] Reference Figure 3 The water-cooled channel 2 includes a cooling pipe 201, which is wound around the outer surface of the vacuum furnace 1. A diversion pipe 202 is connected to the cooling pipe 201. The water inlet of the cooling pipe 201 is connected to a water inlet pipe 203, which is connected to a water supply pressurization mechanism. The drain outlet of the cooling pipe 201 is connected to a drain pipe 204, and the end of the drain pipe 204 away from the cooling pipe 201 is connected to the liquid inlet of the cooling water circulator 4.

[0031] Reference Figure 1 and Figure 2 The cooling pipe 201 is spirally wound on the outer surface of the vacuum furnace 1, and the cooling pipe 201 is made of copper.

[0032] Reference Figure 3 The water supply and pressurization mechanism includes a water pump 5, which is mounted on another fixed plate 3. A storage tank 6 is installed on the outer surface of the vacuum furnace 1. An inlet pipe 7 is provided between the storage tank 6 and the water pump 5. The drain port of the storage tank 6 is connected to the inlet of the water pump 5 through the inlet pipe 7. The drain port of the water pump 5 is connected to the inlet pipe 203. In application, by starting the water pump 5, the water pump 5 draws the cooling water in the storage tank 6 into the water pump 5 through the inner cavity of the inlet pipe 7, and then discharges it through the output end of the water pump 5. It is also discharged into the cooling water circulation machine 4 through the inner cavity of the inlet pipe 203, the inner cavity of the cooling pipe 201, the inner cavity of the diversion pipe 202, and the inner cavity of the drain pipe 204. During this period, the cooling water carries away the heat on the vacuum furnace 1 evenly through the heat exchange principle, so as to achieve the effect of heat dissipation of the vacuum furnace 1. This allows the heat on the vacuum furnace 1 to be carried away evenly, thus facilitating the heat dissipation of the vacuum furnace 1.

[0033] Reference Figure 3 A drain pipe 8 is provided between the storage tank 6 and the cooling water circulator 4. The inlet of the storage tank 6 is connected to the outlet of the cooling water circulator 4 through the drain pipe 8. In application, by starting the cooling water circulator 4, the cooling water circulator 4 discharges the cooled water through the inner cavity of the drain pipe 8 into the storage tank 6 for heat dissipation of the vacuum furnace 1, thereby facilitating the circulating cooling of the vacuum furnace 1.

[0034] Reference Figure 3 A water injection pipe 601 is installed on the top of the storage tank 6, and the water injection pipe 601 is connected to the storage tank 6 to inject an appropriate amount of cooling water into the storage tank 6.

[0035] Reference Figure 3 The drain pipe 8 and the inlet pipe 7 are symmetrically arranged along the central axis of the storage tank 6 to facilitate the entry and exit of the cooled water after cooling, thereby facilitating circulating cooling.

[0036] In actual use, when it is necessary to dissipate heat from the vacuum furnace 1, the water pump 5 fixed on the fixed plate 3 is started. At this time, the water pump 5 draws the cooling water in the storage tank 6 into the water pump 5 through the inner cavity of the liquid inlet pipe 7, and then discharges it through the output end of the water pump 5. It is also discharged into the cooling water circulation machine 4 through the inner cavity of the water inlet pipe 203, the inner cavity of the cooling pipe 201, the inner cavity of the diversion pipe 202, and the inner cavity of the drain pipe 204. During this period, the cooling water carries away the heat on the vacuum furnace 1 evenly through the heat exchange principle, so as to achieve the effect of heat dissipation of the vacuum furnace 1. This makes it easier to dissipate heat from the vacuum furnace 1.

[0037] At the same time, by starting the cooling water circulator 4 fixed on the fixed plate 3, the cooling water circulator 4 discharges the cooled water through the inner cavity of the drain pipe 8 into the storage tank 6 for the vacuum furnace 1 to dissipate heat. Meanwhile, the water pump 5 repeats the above steps to complete the circulating cooling of the vacuum furnace 1 until the temperature of the vacuum furnace 1 is cooled to the specified temperature, thus facilitating the circulating cooling of the vacuum furnace 1. This device can not only uniformly remove the heat from the vacuum furnace 1, but also perform circulating cooling.
