Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a side plate of a heat exchanger. Background Art

[0002] The side plates of the heat exchanger are also called baffles. Their purpose is to allow the high-temperature medium to be discharged from both sides of the heat exchanger in a staggered and zigzag manner, so that the high-temperature medium can fully pass through the copper tube bundle and come into contact with the copper tube bundle, thereby achieving efficient heat exchange between the high-temperature medium and the medium inside the copper tube bundle.

[0003] The existing flat-plate baffles will cause the fluid to turn sharply at the baffles, resulting in greater flow resistance, affecting the heat exchange effect, and easily causing vibration and wear problems. Therefore, a heat exchanger side plate is proposed to provide a set of curved side plates in the heat exchanger to replace the existing flat-plate side plates. Since the baffles are curved in the discharge direction with an arc surface, the flow resistance and the formation of vortices can be reduced. The flow velocity distribution of the fluid in the shell side is more uniform, thereby improving the heat exchange efficiency and reducing the direct impact of the fluid on the baffles, thereby reducing the risk of vibration noise and wear. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides a heat exchanger side plate to provide a set of curved side plates in the heat exchanger to replace the existing flat side plates. Since the arc-shaped baffle plate is bent in the discharge direction, it can reduce the flow resistance and the formation of vortexes. The flow velocity distribution of the fluid in the shell side is more uniform, thereby improving the heat exchange efficiency and reducing the direct impact of the fluid on the baffle plate, thereby reducing the risk of vibration noise and wear.

[0005] The technical solution adopted by the utility model to solve its technical problem is a heat exchanger side plate, including a curved side plate, a pipe hole and an overflow section for passing the heat exchanger copper tube. At least one group of the pipe holes is provided, and the pipe holes are opened at equal distances along the curved side plate. An overflow section is provided at one end of the curved side plate for the medium to flow in the heat exchanger.

[0006] By adopting the above technical solution, a set of curved side plates with pipe-through holes and overflow sections is provided in the heat exchanger to replace the existing flat side plates. Since the deflector is curved in the discharge direction, it can reduce the flow resistance and the formation of vortices, and the flow velocity distribution of the fluid in the shell side is more uniform, thereby improving the heat exchange efficiency.

[0007] Specifically, the inner end of the pipe-through hole is provided with a chamfer.

[0008] By adopting the above technical solution, the chamfer can reduce the wear of the copper tube during the penetration of the tube hole.

[0009] Specifically, the curved side plate includes a stainless steel base layer, a shot-peened concave-convex layer, a hot-dip chrome layer and a concave-convex surface layer.

[0010] Specifically, the shot peening concave-convex layer is arranged along the surfaces of both sides of the curved side plate and the inner wall of the through-tube hole.

[0011] Specifically, the hot-dip chrome layer is provided on a stainless steel base layer having a shot-peened concave-convex layer on the surface.

[0012] By adopting the above technical solution, the shot peening concave-convex layer can increase the use strength of the stainless steel base surface, and can better adsorb the hot-dip chrome layer, thereby improving the connection strength between the two.

[0013] The beneficial effects of the present invention are as follows: by providing a set of curved side plates with through-tube holes and overflow sections in the heat exchanger, it is possible to provide a set of curved side plates in the heat exchanger to replace the existing flat side plates. Since the arc-shaped baffles bent in the discharge direction can reduce the flow resistance and the formation of vortices, the flow velocity distribution of the fluid in the shell side is more uniform, thereby improving the heat exchange efficiency, reducing the direct impact of the fluid on the baffles, thereby reducing the risk of vibration, noise and wear, and solving the problem that the existing flat baffles will cause the fluid to turn sharply at the baffles, generate greater flow resistance, affect the heat exchange effect, and easily cause vibration and wear.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to improve the heat transfer efficiency, Figure 1-6 As shown, the utility model describes a heat exchanger side plate, comprising a curved side plate 1, a pipe hole 2 for passing the heat exchanger copper tube, and an overflow section 3. The pipe hole 2 is provided in at least one group and is provided at equal intervals along the curved side plate 1. An overflow section 3 is provided at one end of the curved side plate 1 for the medium to flow in the heat exchanger.

[0024] When in use, a set of curved side plates 1 with pipe holes 2 and overflow sections 3 is provided in the heat exchanger to replace the existing flat side plates. Since the baffles bent in the discharge direction with an arc surface can reduce flow resistance and the formation of vortices, the flow velocity distribution of the fluid in the shell side is more uniform, thereby improving the heat exchange efficiency.

[0025] The inner end of the pipe-through hole 2 is provided with a chamfer 21 .

[0026] During use, the chamfer 21 can reduce the wear of the copper tube during insertion into the through-hole 2.

[0027] In order to improve the strength of the board surface, for example, Figure 1 、 3 As shown, the present invention also includes that the curved side plate 1 includes a stainless steel base layer 11 , a shot blasting concave-convex layer 12 , a hot-dip chrome layer 13 and a concave-convex surface layer 14 .

[0028] The shot peening concave-convex layer 12 is provided along the two side surfaces of the curved side plate 1 and the inner wall of the through-tube hole 2 .

[0029] The hot-dip chrome layer 13 is provided on a stainless steel base layer 11 having a shot-peened concavo-convex layer 12 on its surface.

[0030] During use, the shot peening concave-convex layer 12 can increase the surface strength of the stainless steel base layer 11 and enable better adsorption of the hot-dip chrome layer 13, thereby improving the connection strength between the two and improving the surface strength and wear resistance of the curved side plate 1.

[0031] When the present invention is in use, the bending direction of the curved side plate 1 is set to be consistent with the flow direction, and the curved side plates 1 are staggered in the heat exchanger, so that the overflow section 3 of the curved side plate 1 and the inner wall of the heat exchanger form a tortuous overflow channel for the heat exchange medium. The through-tube hole 2 provides a through-tube channel for the copper tube in the heat exchanger, so that the medium passing through the copper tube can fully exchange heat with the medium passing between the curved side plates 1, so as to replace the existing flat side plates. Since the baffle plate bent in the discharge direction of the arc surface can reduce the flow resistance and the formation of vortex, the flow velocity distribution of the fluid in the shell side is more uniform, thereby improving the heat exchange efficiency and reducing the direct impact of the fluid on the baffle plate, thereby reducing the risk of vibration noise and wear.
