Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for sintering furnaces, and in particular to a water circulation heat dissipation device for a vacuum sintering furnace. Background Technology

[0002] A vacuum sintering furnace is a furnace that performs protective sintering of heated materials in a vacuum environment. It employs various heating methods, such as resistance heating, induction heating, and microwave heating. Vacuum sintering furnaces utilize induction heating for protective sintering of heated materials and can be categorized into types such as power frequency, medium frequency, and high frequency, and can be classified as a subcategory of vacuum sintering furnaces.

[0003] Vacuum sintering furnaces use a water circulation cooling system during operation. However, the existing water circulation system has poor heat dissipation performance, resulting in a low cooling rate for the vacuum sintering furnace and reducing its operating efficiency.

[0004] Therefore, it is essential to provide a water circulation heat dissipation device for vacuum sintering furnaces to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a water circulation cooling device for a vacuum sintering furnace. Heat exchange is achieved through a cooling coil installed on the inner liner of the sintering furnace body. The installation of the cooling coil increases the contact area and improves heat exchange efficiency. During water circulation, a transfer water tank installed at one end of the outlet pipe thoroughly stirs the incoming circulating water. Simultaneously, the cooling fins on both sides of the transfer water tank rapidly exchange heat, and the cooling fan installed on the circulating water tank provides rapid cooling, improving the heat dissipation effect of the circulating water within the transfer water tank. This quickly reduces the temperature of the sintering furnace body and improves the efficiency of the vacuum sintering furnace.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] A water circulation heat dissipation device for a vacuum sintering furnace is provided, including a sintering furnace body, an inner liner installed inside the sintering furnace, a heat dissipation box installed outside the sintering furnace body, a circulating water tank installed at the bottom of the heat dissipation box, a circulating pump installed in the circulating water tank, and a heat dissipation mechanism connected to the circulating water tank.

[0008] The heat dissipation mechanism includes a circulating water pipe connected to a circulating pump and a heat dissipation coil. The heat dissipation coil is wrapped around the outside of the inner tank, and the other end of the heat dissipation coil is connected to an outlet pipe. A heat dissipation component is connected through the heat dissipation box on the outlet pipe, and the heat dissipation component is connected to the top of the circulating water tank.

[0009] Specifically, the heat dissipation component includes a transfer water tank, a connecting rod installed in the center of the transfer water tank, a stirring fan blade mounted on the connecting rod, and heat dissipation fins installed on the outside of the transfer water tank.

[0010] Specifically, the transfer tank has a conical structure at both the top and bottom, and a diversion pipe is installed on the top of the transfer tank.

[0011] Specifically, two sets of cooling fans are installed at both ends of the top of the circulating water tank, with the cooling fans installed directly below the heat dissipation fins.

[0012] Specifically, the heat sink is installed on top of the circulating water tank, and heat dissipation windows are opened on both sides of the heat sink.

[0013] This invention utilizes a heat exchange coil installed on the inner liner of the sintering furnace body for heat exchange. The installation of the heat exchange coil increases the contact area and improves the heat exchange efficiency. During water circulation, a transfer water tank installed at one end of the outlet pipe can fully agitate the incoming circulating water. At the same time, the heat exchange fins on both sides of the transfer water tank rapidly exchange heat, and the cooling fan installed on the circulating water tank provides rapid cooling, improving the heat dissipation effect of the circulating water in the transfer water tank. This can quickly reduce the temperature of the sintering furnace body and improve the efficiency of the vacuum sintering furnace. Attached Figure Description

[0035] The present invention will be further described in conjunction with the following embodiments.

[0036] Example 1:

[0037] like Figure 1-2 As shown, a water circulation heat dissipation device for a vacuum sintering furnace includes a sintering furnace body 1, an inner liner 2 installed inside the sintering furnace, a heat dissipation box 3 installed outside the sintering furnace body 1, a circulating water tank 4 installed at the bottom of the heat dissipation box 3, a circulating pump 5 installed in the circulating water tank 4, and a heat dissipation mechanism 6 connected to the circulating water tank 4.

[0038] When the sintering furnace body 1 is in use, the inner liner 2 is cooled by water circulation through the heat dissipation mechanism 6. The water circulation of the heat dissipation mechanism 6 includes a heat dissipation box 3 and a circulating water tank 4 installed at the bottom. The circulating pump 5 installed in the circulating water tank 4 pumps the circulating water after heat exchange.

[0039] The heat dissipation mechanism 6 includes a circulating water pipe 7, which is connected to the circulating pump 5. The circulating water pipe 7 is connected to a heat dissipation coil 8, which is wrapped around the outside of the inner tank 2. The other end of the heat dissipation coil 8 is connected to an outlet pipe 9, which passes through the heat dissipation box 3 and is connected to a heat dissipation component 10. The heat dissipation component 10 is connected to the top of the circulating water tank 4.

[0040] The circulating water pipe 7 in the heat dissipation component 10 is connected to the circulating pump 5 installed in the circulating water tank 4. The circulating water pump pumps water medium through the circulating water pipe 7 to the heat dissipation coil 8, where the heat dissipation coil 8 exchanges heat with the inner tank 2. After heat exchange through the heat dissipation coil 8, the water medium flows out through the outlet pipe 9. The heat dissipation component 10 connected to the outlet pipe 9 further dissipates heat from the water medium, so that the water medium entering the circulating water tank 4 can be quickly cooled and the heat can be carried away.

[0041] The heat dissipation assembly 10 includes a transfer water tank 11, a connecting rod 12 is installed in the center inside the transfer water tank 11, a stirring fan blade 13 is rotatably installed on the connecting rod 12, and heat dissipation fins 14 are installed on the outside of the transfer water tank 11.

[0042] When the water medium in the outlet pipe 9 falls into the transfer water tank 11, the flow of water drives the stirring fan blades 13 installed on the connecting rod 12 to stir and disperse the water medium, increase the contact area of ​​the water medium, and improve the heat dissipation effect. At the same time, the heat dissipation fins 14 installed on the outside of the transfer water tank 11 can improve the heat conduction and heat exchange efficiency.

[0043] The transfer water tank 11 has a conical structure at both the top and bottom. A diversion pipe 15 is installed on the top of the transfer water tank 11. The diversion pipe 15 installed on the transfer water tank 11 can divert the water medium, which facilitates the water medium to flow into the stirring fan 13 inside the transfer water tank 11 to cooperate and improve the cooling efficiency.

[0044] Two sets of cooling fans 16 are installed at both ends of the top of the circulating water tank 4. The cooling fans 16 are installed directly below the heat dissipation fins 14. The cooling fans 16 can cool down the heat dissipation fins 14 installed at the top, thereby improving the heat exchange and cooling effect of the heat dissipation fins 14.

[0045] The heat sink 3 is installed on top of the circulating water tank 4. Heat dissipation windows 17 are provided on both sides of the heat sink 3. The opening of the heat dissipation windows 17 can discharge the temperature after the heat exchange between the cooling fan 16 and the heat dissipation fins 14, and at the same time use external air source to cool the transfer box.

[0046] During the production process, heat exchange is achieved through the heat dissipation coil 8 installed on the inner liner 2 inside the sintering furnace body 1. The installation of the heat dissipation coil 8 increases the contact area and improves the heat exchange efficiency. During the water circulation process, the intermediate water tank 11 installed at one end of the outlet pipe 9 can fully stir the incoming circulating water. At the same time, the heat dissipation fins 14 set on both sides of the intermediate tank quickly exchange heat and are rapidly cooled by the cooling fan 16 installed on the circulating water tank 4, which improves the heat dissipation effect of the circulating water in the intermediate water tank 11, can quickly reduce the temperature of the sintering furnace body 1, and improve the efficiency of the vacuum sintering furnace.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
