Description

A sealing flange with cooling circuit

technical field

The invention relates to the technical field of flanges, in particular to a sealing flange with a cooling circuit.

Background technique

At present, some equipment usually uses sealing flanges to cooperate with fittings to seal gas or liquid. For example, Hydride Vapor Phase Epitaxy (HVPE, Hydride Vapor Phase Epitaxy) equipment, which is a _compound growth process equipment, is mainly used to epitaxially grow a layer of Thick films or crystals such as GaAs, GaN, etc. Since hydride gases such as H ₂ and HCl are dangerous gases, these dangerous gases need to be sealed in the quartz tube of the HVPE equipment through the sealing flange and the sealing ring. Once leaked, it will cause serious consequences. However, due to the long-term high-temperature environment of HVPE equipment, the sealing ring is easily burned out. If the sealing ring cannot be replaced in time, it will cause dangerous gas leakage. The usual practice is to cool down the sealing flange, and the temperature of the sealing ring in close contact with the sealing flange is lowered according to the principle of temperature conduction, thereby prolonging the service life of the sealing ring.

As shown in Figure 1, it is a side view of a sealing flange with a cooling circuit in the prior art, and as shown in Figure 2, it is a bottom view of a sealing flange with a cooling circuit in the prior art, as shown in Figure 3 A cross-sectional view in the direction of A-A in FIG. 2 , and FIG. 4 is a schematic diagram of the circulation direction of cooling water when the sealing flange with cooling circuit in the prior art is cooling. It can be seen from Figures 1 to 4 that the structure of the sealing flange mainly includes a bottom 1, a side wall 2, an edge 3, a water inlet 4, a water outlet 5, and a baffle 6, and a center of the bottom 1 is provided for connecting external parts. The connecting hole 11, the baffle plate 6 is located between the water inlet 4 and the water outlet 5, when cooling the sealing flange, the cooling water (the dotted line in Figure 4 represents the flow route of the cooling water) enters the side from the water inlet 4 One side of the wall 2 flows to the other side of the side wall 2 under the blocking of the baffle plate 6, and at the same time flows from one side of the bottom 1 to the other side. When the water level in the wall 2 is higher than the water outlet 5, the cooling water flows out from the water outlet 5, thereby realizing the circulation cooling of the sealing flange.

However, when the sealing flange of the above-mentioned structure is cooled, it is easy to cause cooling dead angles at the bottom, side walls or edges, especially at places far away from the water inlet and water outlet, and the cooling effect will be greatly affected. For example, since the position of the water outlet 5 is on the outer surface of the side wall 2, the water level will flow out when the water level exceeds the water outlet 5, so the cooling water can only be cooled to the part of the side wall 2 below the water outlet 5, and the part above the water outlet 5 The side wall 2 and the edge 3 cannot be cooled, resulting in the formation of a cooling dead angle, which greatly affects the cooling effect. For another example, due to the large area of the bottom 1 and no cooling circuit, the cooling water cannot be circulated and cooled well. The newly entered cooling water may flow directly from the 4 near the water inlet to the 5 near the water outlet, and the 4 and the cooling water farther from the water outlet 5 have heated up, but there is less exchange with the newly entered cooling water, thereby forming a cooling dead angle, and the cooling effect is poor.

Therefore, how to improve and design the cooling circuit in the sealing flange, eliminate the cooling dead angle, and improve the cooling effect is an urgent problem to be solved.
