Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a cooling rack for magnetic core sintering. Background Art

[0002] Magnetic core sintering is a process for preparing magnetic materials. It is done by pressing powder materials into shape at high temperature and heating them under specific conditions so that the powder particles combine with each other to form a solid magnetic core. During the preparation of the magnetic core, a large amount of heat will be generated due to the high-temperature treatment, and the magnetic core needs to be sintered within the appropriate temperature range to ensure its quality and performance. In order to control the temperature during the sintering process and prevent the magnetic core from overheating, a cooling rack is required for thermal management. The cooling rack can discharge excess heat from the magnetic core through circulating cooling, conductive heat dissipation, etc. to maintain a suitable sintering temperature. The cooling rack can also prevent excessive temperature gradients and avoid damage to the magnetic core material caused by thermal stress.

[0003] Most of the cooling racks currently on the market use water cooling for cooling. When the water-cooling liquid reaches the end position of the water-cooling tube, the water-cooling liquid at the end position absorbs more heat, causing the temperature of the water-cooling liquid to become higher, and the ability of the water-cooling liquid to absorb heat will also become lower, causing the temperature of the magnetic core at the end to drop slowly, and the magnetic core at the end position cannot be effectively cooled. Some cooling racks need to use a large amount of cooling water to cool the magnetic core when water cooling. When faced with a large number of magnetic cores that need to be cooled, these cooling racks need a lot of cooling water to meet the demand, which will cause certain waste.

[0004] Therefore, it is urgent to provide a cooling rack for magnetic core sintering to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that most of the cooling racks currently on the market use water cooling for cooling. When the water-cooling liquid reaches the end position of the water-cooling tube, the water-cooling liquid at the end position absorbs more heat, resulting in the temperature of the water-cooling liquid becoming higher, and the ability of the water-cooling liquid to absorb heat will also become lower, resulting in the temperature of the magnetic core at the end dropping slowly, and the magnetic core at the end position cannot be effectively cooled. When some cooling racks are water-cooled, a large amount of cooling water is needed to cool the magnetic core. When faced with a large number of magnetic cores that need to be cooled, these cooling racks need a lot of cooling water to meet the demand, which will cause certain waste.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a cooling rack for magnetic core sintering, comprising a plurality of frames, a plurality of support rods are fixedly connected between the plurality of frames, a first heat dissipation tube and a second heat dissipation tube are respectively installed inside the plurality of frames, a plurality of magnetic cores are slidably connected to the tops of the plurality of the first heat dissipation tubes and the second heat dissipation tubes, and a connecting tube is fixedly connected to the water inlet and the water outlet of the plurality of the first heat dissipation tubes and the second heat dissipation tubes;

[0007] A water tank is installed on one side of the multiple frames, a plurality of fixing plates are installed on one side of the water tank close to the frame, a first water pump is installed on the top of each of the multiple fixing plates, and a cooling plate is installed inside the water tank;

[0008] A first water pipe is fixedly connected to the bottom position of one side of the front end of the cooling plate, and a second water pipe is fixedly connected to the top position of the other side of the front end of the cooling plate. A cooling assembly is installed between the first water pipe and the second water pipe, and a second water pump is installed on the outer wall of the first water pipe.

[0009] The utility model is further configured as follows: the plurality of first heat dissipation tubes and second heat dissipation tubes are all made of metal material.

[0010] Through the above technical solution, the first heat dissipation tube and the second heat dissipation tube made of metal material have a stable structure and sufficient strength, which can not only support the multiple magnetic cores, but also absorb and dissipate heat well.

[0011] The utility model is further configured as follows: a plurality of the first heat dissipation tubes and the second heat dissipation tubes are all installed on the inner wall of the frame in a serpentine structure, and the first heat dissipation tubes and the second heat dissipation tubes are fitted to each other.

[0012] Through the above technical solution, the serpentine structure can significantly increase the surface area of ​​the first heat dissipation tube and the second heat dissipation tube. Compared with the traditional straight shape, the first heat dissipation tube and the second heat dissipation tube with a serpentine structure can provide more heat dissipation surfaces, thereby effectively improving the heat conduction and dissipation capabilities. The serpentine structure can also guide the fluid to form eddies or vortices inside the first heat dissipation tube and the second heat dissipation tube, increase the contact area between the fluid and the first heat dissipation tube and the second heat dissipation tube, and increase the fluid flow rate, which helps to enhance the heat transfer effect and improve the heat dissipation efficiency.

[0013] The utility model is further configured as follows: a plurality of magnetic cores are distributed in an array on the top of the first heat dissipation tube and the second heat dissipation tube.

[0014] Through the above technical solution, as many magnetic cores as possible can be arranged on the top of the first heat dissipation tube and the second heat dissipation tube for cooling, thereby greatly improving the cooling efficiency of the magnetic cores.

[0015] The utility model is further configured as follows: one of the first water pumps is installed at the water inlet of the first radiating pipe, and another of the first water pumps is installed at the water outlet of the second radiating pipe.

[0016] Through the above technical solution, cooling water enters the first heat dissipation tube from the water inlet of the first heat dissipation tube, and absorbs heat and cools the multiple high-temperature magnetic cores on the top of the first heat dissipation tube and the second heat dissipation tube when flowing through the first heat dissipation tube. When the cooling water reaches the end position of the first heat dissipation tube, the temperature of the cooling water is very high at this time, and the multiple high-temperature magnetic cores on the top of the first heat dissipation tube and the second heat dissipation tube cannot be cooled, which will cause the high-temperature magnetic cores at the end position of the first heat dissipation tube to be unable to be cooled. When another first water pump is installed at the water outlet of the second heat dissipation tube, the cooling water will enter the second heat dissipation tube from the water outlet of the second heat dissipation tube, which can well cool the high-temperature magnetic cores on the end of the first heat dissipation tube, so that the high-temperature magnetic cores on the entire first heat dissipation tube and the second heat dissipation tube can be effectively cooled.

[0017] The utility model is further configured as follows: a plurality of partitions are installed inside the water tank, and the partitions are provided with through holes corresponding to the cooling plates.

[0018] Through the above technical solution, multiple partitions can divide the water tank into multiple compartments, so that the cooling water inside each compartment can quickly enter the corresponding first heat dissipation pipe and second heat dissipation pipe for subsequent cooling work.

[0019] The utility model is further configured as follows: the cooling assembly is composed of a coolant tank, a temperature sensor, and electronic valve parts.

[0020] Through the above technical solution, the coolant inside the coolant tank will be transported to the cooling plate by the second water pump. The coolant inside the cooling plate can absorb the heat in the cooling water, ensuring that the cooling water entering the water tank will not affect subsequent cooling work.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. The utility model is designed to install a water pump at the water inlet of the first radiating pipe and the water outlet of the second radiating pipe, and the cooling water is pumped into the first radiating pipe and the second radiating pipe by the water pump. The two cooling waters flowing in opposite directions can effectively reduce the temperature of the magnetic cores on the first radiating pipes and the second radiating pipes, and the magnetic cores in local positions will not be unable to be cooled, which will affect the work quality.

[0023] 2. The utility model designs the first heat dissipation tube and the second heat dissipation tube with a serpentine structure. The serpentine structure can significantly increase the surface area of ​​the first heat dissipation tube and the second heat dissipation tube, thereby effectively improving the heat conduction and heat dissipation capabilities. The serpentine structure can also guide the fluid to form eddies or vortices inside the first heat dissipation tube and the second heat dissipation tube, increase the contact area between the fluid and the first heat dissipation tube and the second heat dissipation tube, and increase the fluid flow rate, which helps to enhance the heat transfer effect and improve the heat dissipation efficiency;

[0024] 3. The utility model is designed with a matching cooling component, through which the coolant inside the cooling component can be transported to the water tank, so that the cooling water inside the water tank can be quickly cooled, so that the cooling water re-entering the water inlet of the first heat dissipation pipe will not affect the subsequent cooling work.

The tops of the multiple first heat dissipation tubes 3 and the second heat dissipation tubes 4 are slidably connected with multiple magnetic cores 5, and the multiple magnetic cores 5 are distributed in an array on the tops of the first heat dissipation tubes 3 and the second heat dissipation tubes 4. In this way, as many magnetic cores 5 as possible can be arranged on the tops of the first heat dissipation tubes 3 and the second heat dissipation tubes 4 for cooling, greatly improving the cooling efficiency of the magnetic cores 5, and the water inlets and outlets of the multiple first heat dissipation tubes 3 and the second heat dissipation tubes 4 are fixedly connected with connecting pipes 6.

[0033] like Figure 4 and Figure 5As shown, a water tank 7 is installed on one side of the multiple frames 1, and a plurality of fixing plates 8 are installed on the side of the water tank 7 close to the frame 1. A first water pump 9 is installed on the top of the multiple fixing plates 8, wherein one of the first water pumps 9 is installed at the water inlet of the first radiating tube 3, and another first water pump 9 is installed at the water outlet of the second radiating tube 4. The cooling water enters the first radiating tube 3 from the water inlet of the first radiating tube 3. When flowing through the first radiating tube 3, the multiple high-temperature magnetic cores 5 at the top of the first radiating tube 3 and the second radiating tube 4 are subjected to heat absorption and cooling. When the cooling water reaches the end position of the first radiating tube 3, the temperature of the cooling water is very high at this time, and the multiple high-temperature magnetic cores 5 at the top of the first radiating tube 3 and the second radiating tube 4 cannot be cooled, which will cause the high-temperature magnetic cores 5 at the end position of the first radiating tube 3 to be unable to be cooled. When another first water pump 9 is installed at the water outlet of the second radiating tube 4, the cooling water will enter the second radiating tube 4 from the water outlet of the second radiating tube 4, which can well cool the high-temperature magnetic cores 5 at the end of the first radiating tube 3, so that the entire first radiating tube 3 can be cooled. The high-temperature magnetic core 5 on the first heat dissipation tube 3 and the second heat dissipation tube 4 can be effectively cooled down. A cooling plate 10 is installed inside the water tank 7. A plurality of partitions are installed inside the water tank 7, and the partitions are provided with through holes corresponding to the cooling plate 10. The plurality of partitions can divide the water tank 7 into a plurality of compartments, so that the cooling water inside each compartment can quickly enter the corresponding first heat dissipation tube 3 and the second heat dissipation tube 4 for subsequent cooling work. The front end of the cooling plate 10 is fixedly connected with a first water pipe 11 at the bottom position on one side, and the front end of the cooling plate 10 is fixedly connected with a second water pipe 12 at the top position on the other side. A cooling assembly 13 is installed between the first water pipe 11 and the second water pipe 12. The cooling assembly 13 consists of a coolant tank, a temperature sensor, and electronic valve parts. The coolant inside the coolant tank will be transported to the cooling plate 10 by a second water pump 14. The coolant inside the cooling plate 10 can absorb the heat in the cooling water to ensure that the cooling water entering the water tank 7 will not affect the subsequent cooling work. The outer wall of the first water pipe 11 is installed with a second water pump 14.

[0034] When the utility model is in use, the staff needs to evenly place the magnetic cores 5 to be cooled on the first heat dissipation tube 3 and the second heat dissipation tube 4. The first heat dissipation tube 3 and the second heat dissipation tube 4 made of metal material have a stable structure and sufficient strength, which can not only play a supporting role for the multiple magnetic cores 5, but also can perform heat absorption cooling very well. The first heat dissipation tube 3 and the second heat dissipation tube 4 installed on the inner wall of the frame 1 in a serpentine structure have more heat dissipation surfaces, thereby effectively improving the heat conduction and dissipation capabilities. The serpentine structure can also guide the fluid to form eddies or vortices inside the first heat dissipation tube 3 and the second heat dissipation tube 4, increase the contact area between the fluid and the first heat dissipation tube 3 and the second heat dissipation tube 4, and increase the fluid flow rate, which helps to enhance the heat transfer effect and improve the heat dissipation efficiency. After completing the work of placing the multiple magnetic cores 5, the multiple first water pumps 9 can be started at this time, and the cooling water inside the water tank 7 is pumped into the corresponding first heat dissipation tube 3 and the second heat dissipation tube 4 through the multiple first water pumps 9. The cooling water enters the first heat dissipation tube 3 from the water inlet of the first heat dissipation tube 3. When flowing through the first heat dissipation tube 3, it will affect the top of the first heat dissipation tube 3 and the second heat dissipation tube 4. The multiple high-temperature magnetic cores 5 absorb heat and cool down. When the cooling water reaches the end of the first heat dissipation tube 3, the temperature of the cooling water is very high at this time, and the multiple high-temperature magnetic cores 5 at the top of the first heat dissipation tube 3 and the second heat dissipation tube 4 cannot be cooled down. This will cause the high-temperature magnetic cores 5 at the end of the first heat dissipation tube 3 to be unable to be cooled down. Another first water pump 9 is installed at the water outlet of the second heat dissipation tube 4, and the cooling water will enter the second heat dissipation tube 4 from the water outlet of the second heat dissipation tube 4, which can well cool the high-temperature magnetic cores 5 at the end of the first heat dissipation tube 3, so that the entire The high-temperature magnetic cores 5 on the first heat dissipation tube 3 and the second heat dissipation tube 4 can be effectively cooled. When the multiple first water pumps 9 are working, the second water pump 14 will also work synchronously. It will pump the coolant inside the cooling component 13 into the cooling plate 10. The coolant in the cooling plate 10 will absorb the heat of the cooling water entering the water tank 7, so that the cooling water re-entering the water inlet of the first heat dissipation tube 3 will not affect the subsequent cooling work. After cooling to a certain temperature, the staff can collect the multiple magnetic cores 5 and carry out the next cooling work of the magnetic cores 5.
