Description

Technical Field

[0001] The present invention belongs to the field of blowers, and particularly relates to a vacuum-insulated water-cooling mechanism and an air-suspension blower using the vacuum-insulated water-cooling mechanism. Background Art

[0002] In daily life or industrial equipment, high-temperature isolation maintenance and / or cooling operations are often used. Water-cooled heat insulation is widely used in the field of high-temperature heat insulation because it has good water-cooled heat insulation effect, high efficiency, and is an effective heat insulation method. There are generally two types of existing water-cooled heat insulation plates. One is to directly process a water tank inside the heat insulation plate for water-cooled heat insulation. The layout of this water tank is single, and the heat insulation effect is not very ideal. The other is to process a groove inside the heat insulation plate and embed a copper pipe for water flow in the groove. This water-cooled heat insulation plate adds a layer of copper pipe, resulting in lower efficiency than direct water cooling and higher manufacturing cost. Currently, both of these water-cooled heat insulation methods have relatively large heat losses at the high-temperature end.

[0003] However, in practice, it is also necessary to maintain the high-temperature end at a high-temperature state and the low-temperature end at a low-temperature state. Currently, some water-cooling mechanisms cannot block the heat at the high-temperature end and the low-temperature end, and the heat energy cross-flow cannot keep the equipment at the high and low temperatures required in practice. Summary of the Invention

[0004] The present invention aims to solve the problems of unreasonable structure of the existing water-cooling device, unsatisfactory heat insulation and cooling effects, and large heat losses at the high-pressure and high-temperature ends.

[0005] A vacuum-insulated water-cooling mechanism disclosed by the present invention includes a water-cooling partition assembly and a vacuum heat insulation plate assembled together; the vacuum heat insulation plate is provided with a cavity for being evacuated for heat insulation, and is installed on the side close to the high-temperature components to isolate high temperature and prevent heat conduction; the water-cooling partition assembly is provided with a sealed pipeline through which cold water can flow, and a water inlet and a water outlet of the pipeline are arranged outside. When installed, it is on the side close to the components with a need for cooling. Thus, the state maintenance at the high-temperature and high-pressure end and the cooling requirement at the other end are achieved simultaneously; the heat energy at the high-temperature end is not lost, and the burden on the water-cooling partition assembly is not increased.

[0006] Optionally, the vacuum heat insulation plate is an independent component with an evacuated cavity inside, and then assembled with the water-cooling partition assembly. The advantage is convenient maintenance.

[0007] Preferably, the vacuum heat insulation plate and the water-cooling partition assembly are hermetically connected after assembly to jointly form a cavity that can be evacuated inside to achieve high-temperature isolation. The advantage of this solution is fewer parts, simple structure, and low manufacturing cost.

[0008] Preferably, the sealed pipe for flowing cold water in the water-cooled partition plate assembly is a multi-turn disc-shaped pipe, and a water inlet pipe and a water outlet pipe are externally connected to the water inlet and the water outlet respectively. The advantages are large cooling area and good effect.

[0009] Optionally, the multi-turn disc-shaped pipe is integrally formed by a mold. The advantage is that the pipe sealing is easy.

[0010] Preferably, the water-cooled partition plate assembly includes a water-cooled cover plate and a water-cooled bottom plate. Half of the grooves of the pipe are formed on the water-cooled cover plate, and the other half of the mirror-symmetrical grooves are on the water-cooled bottom plate. After assembly, they are combined together to form a complete flowing water pipe, and ensure that the pipe is sealed and does not leak water. Since the bottom plate grooves and the cover plate grooves are mirror-symmetrical, the formation of the groove part can be shared, which also saves the processing and manufacturing costs, and it is easy to form the consistency of the pipe after mirroring.

[0011] Preferably, the materials of the vacuum insulation board and the water-cooled partition plate assembly are both made of stainless steel.

[0012] The present invention also discloses an air suspension blower using a vacuum insulation and water-cooling mechanism. The vacuum insulation board is close to the high-temperature and high-pressure components of the air suspension blower, including the components of the impeller and the volute; the water-cooled partition plate assembly is close to the components containing the motor.

[0013] Furthermore, the back of the impeller and the vacuum insulation board are engaged by labyrinth teeth, because the labyrinth teeth engagement can prevent the high-temperature and high-pressure gas from leaking into the gaps of relevant parts through the gap at the back of the impeller, generating axial unbalanced force and damaging the internal parts, and also resulting in a decrease in the air outlet rate.

[0014] The above series of disclosed technical solutions enable the implementation of the present invention to effectively solve the defects existing in the background technology. The present invention enables the high-temperature and high-pressure end not to conduct heat to the components that need to be cooled, which not only makes the heat energy at the high-temperature end not lost, but also does not increase the burden on the cooling end. The structural design of the cooling mechanism described in the present invention is novel and reasonable, effectively realizing the function of the cooling components, reducing the manufacturing cost, and improving the service life of the components and the air outlet efficiency of the air suspension blower.

[0016] A vacuum-insulated water-cooling mechanism for specific implementation is disclosed herein. As Figure 1 and Figure 2 shown, it includes a water-cooled partition assembly 9 and a vacuum insulation plate 5, which are hermetically connected after assembly to jointly form a cavity 8 that can be evacuated internally; on the side of the vacuum insulation plate 5 close to the high-temperature components, it is used to isolate high temperature and prevent heat conduction; the water-cooled partition assembly 9 is provided with a sealed cooling water pipe 6 through which cold water can flow, close to the side of the components that require cooling, and has a water inlet and a water outlet for the cooling water pipe 6 on the outside. In this way, the state maintenance at the high-temperature and high-pressure end and the isolation of the other end that requires cooling are achieved simultaneously. In addition, as Figure 1 shown, a water outlet pipe 3 and a water inlet pipe 4 are externally connected to the water outlet and the water inlet respectively.

[0017] In order to have a larger area for cold water to flow through and better cooling effect, the cooling water pipe 6 is a multi-turn disk-shaped pipe. As Figure 3 shown, among them, the water-cooled partition assembly 9 is composed of a water-cooled cover plate 2 and a water-cooled bottom plate 1. Half of the grooves of the multi-turn disk-shaped cooling water pipe 6 are formed on the water-cooled cover plate 2, and the other half of the mirror-symmetrical grooves are formed on the water-cooled bottom plate 1. After the water-cooled bottom plate 1 and the water-cooled cover plate 2 are assembled, the two grooves are combined to form a complete cooling water circulation pipe 6, and it is ensured that the cooling water pipe 6 is sealed and does not leak water. Among them, the materials of the vacuum insulation plate 5 and the water-cooled partition assembly 9 are both selected as stainless steel. Of course, there should be other applicable materials. In this embodiment, the number of components is small, the structure is simple, the manufacturing cost is low, and it is also easy to achieve the desired technical effects. Example 2

[0018] A gas suspension blower using a vacuum-insulated water-cooling mechanism for specific implementation is disclosed herein. As Figure 4 shown, it uses the vacuum-insulated water-cooling mechanism in Example 1, where the vacuum insulation plate 5 is close to the impeller assembly of the gas suspension blower, including the impeller and the volute casing assembly. Because in the gas suspension blower, the air inlet of the impeller is often at normal temperature and pressure, but the air coming out of the edge of the impeller in the volute is at high temperature and high pressure; the water-cooled partition assembly 9 is close to the assembly containing the motor and is necessary for cooling. In this embodiment, as Figure 4 and 5As shown, between the back of the impeller and the vacuum heat insulation plate 5, there is a labyrinth seal 7 engaged. The engagement of the labyrinth seal 7 can not only prevent high-temperature and high-pressure gas from leaking into the gaps of the axial related components through the gaps, generating axial unbalanced forces and damaging the internal parts, but also improve the air output rate of the blower.

[0019] The vacuum heat insulation and water cooling mechanism provided by the present invention well solves the problems proposed in the background technology. The heat insulation of the vacuum layer not only realizes that the heat energy at the high-temperature end is not lost, but also does not increase the burden of cooling for the water cooling partition assembly, effectively improving the cooling effect and efficiency. The structure design of the present invention is novel and reasonable, and also reduces the manufacturing cost.
