Temperature adjusting passing roller

Abstract

When the temperature adjusting passing roller is used, water flow enters from a water inlet pipe and then is divided into two paths, namely forward flow and reverse flow, the forward flow flows to an inner water inlet pipe from the water inlet pipe, flows to a slit cavity, then enters an inner backflow pipe and then flows to the end, relatively close to the water inlet pipe, of the inner backflow pipe in the reverse direction, and the reverse flow flows to the end, relatively close to the water inlet pipe, of the inner backflow pipe. The water flows into the backflow cavity and finally flows to the water outlet cavity through the water outlet hole. According to reverse flow, water flow enters the supporting pipe, flows into the inner cavity through the inner water inlet hole, then flows into the end, close to the second mesh plate, of the fin through the second mesh hole, flows to the end, close to the water inlet pipe, of the fin, then enters the gap between the first mesh plate and the inner backflow pipe, finally enters the backflow cavity and finally flows out of the water outlet cavity. The passing roller has a downstream flow direction and a countercurrent flow direction, so that the temperature of the roller surface is more uniform, and the temperature is more uniform when a pole piece is cooled or heated.

The reverse flow: after the water flow enters the water inlet pipe, it flows into the support pipe through the hollow part of the ring piece. Since the support pipe is provided with an internal water inlet hole, the internal water inlet hole connects the internal cavity and the support pipe, and the water flow flows into the internal cavity through the internal water inlet hole, and then flows into the first fin groove through the second mesh hole. Since the first through hole is connected to the first fin groove, it then enters the gap between the first mesh plate and the internal reflux pipe, and finally enters the reflux chamber and flows out from the water outlet chamber. The water flow inside the temperature-adjusting over-roller provided by the present utility model has two flow directions, forward flow and reverse flow, which can make the temperature of the roller surface more uniform.

Each fin 12 is connected to the outer wall of the inner return tube 3, and the fins 12 all protrude from both ends of the inner return tube 3 along the axial direction of the outer roller tube 1. A plurality of first fin grooves 121 and a plurality of second fin grooves 122 are formed between the outer roller tube 1 and each fin 12, and each first fin groove 121 and each second fin groove 122 are arranged alternately; the edge of the first mesh plate 4 is connected to the end of the fin 12 relative to the end close to the water inlet pipe 22. A ring-shaped first support part 43 is connected between the first mesh plate 4 and the inner return tube 3. A first through hole 431 is provided on the first support part 43, and the first through hole 431 is communicated with the first fin groove 121; the edge of the second mesh plate 5 is connected to the other end of the fin 12. A ring-shaped second support part 44 is connected between the second mesh plate 5 and the inner return tube 3. A second through hole 441 is provided on the second support part 44, and the second through hole 441 is communicated with the second fin groove 122; a second mesh 51 is provided on the outer edge of the second mesh plate 5. The second mesh plate 5, the side plate 11 close to the second mesh plate 5, and the outer roller tube 1 enclose an inner chamber 52, and the second mesh 51 communicates the inner chamber 52 with the first fin groove 121; an inner water inlet hole 24 is provided on the support tube 2, and the inner water inlet hole 24 communicates the inner chamber 52 and the support tube 2; both ends of the side water inlet pipe 6 are respectively connected to the first mesh plate 4 and the side plate 11 close to the first mesh plate 4, and the side water inlet pipe 6 is sleeved on the outer wall of the support tube 2. The first mesh plate 4, the side plate 11 close to the first mesh plate 4, and the side water inlet pipe 6 enclose a return chamber 61. A first mesh 41 is provided on the first mesh plate 4, and the first mesh 41 communicates the return chamber 61 and the inner return tube 3; the first mesh plate 4, the side plate 11 close to the first mesh plate 4, the side water inlet pipe 6, and the outer roller tube 1 enclose a slit chamber 62. A third mesh 42 is further provided on the first mesh plate 4, and the third mesh 42 communicates the second fin groove 122 and the slit chamber 62; an inner water inlet pipe 25 and a water outlet hole 26 are further provided on the support tube 2. The inner water inlet pipe 25 is close to the first mesh plate 4 relative to the ring plate 21. Both ends of the inner water inlet pipe 25 are respectively connected to the side wall of the support tube 2 and the side water inlet pipe 6, and the inner water inlet pipe 25 is communicated with both the support tube 2 and the inner water inlet pipe 25. The water outlet hole 26 communicates the return chamber 61 and the water outlet chamber 23.When the temperature - regulating over - roller is in use, the water flow enters from the water inlet pipe 22 and is divided into two routes, namely the forward flow and the reverse flow. Among them, for the forward flow: the water flows from the water inlet pipe 22 to the inner water inlet pipe 25, and then to the slit chamber 62. Since the third mesh hole 42 connects the second fin groove 122 and the slit chamber 62, the water flow passes through the third mesh hole 42 to the fin 12. The fin 12 can increase the heat - exchange surface area of the outer roller tube 1 and improve the heat - exchange efficiency between the outer roller tube 1 and the pole piece. Then it flows to the end of the fin 12 close to the second mesh plate 5. The water flow in the second fin groove 122 flows out from the second through - hole 441, enters the gap between the second mesh plate 5 and the inner return pipe 3, then enters the inner return pipe 3, and flows to the end of the inner return pipe 3 relatively close to the water inlet pipe 22, and then flows into the gap between the first mesh plate 4 and the inner return pipe 3. Since the first mesh plate 4 is provided with the first mesh hole 41, and the first mesh hole 41 connects the return chamber 61 and the inner return pipe 3, the water flow flows into the return chamber 61, and the water outlet hole 26 connects the return chamber 61 and the water outlet chamber 23. Finally, the water flow flows through the water outlet hole 26 to the water outlet chamber 23. For the reverse flow: after the water flow enters the water inlet pipe 22, it flows into the support pipe 2 through the hollow part of the ring piece 21. Since the support pipe 2 is provided with the inner water inlet hole 24, and the inner water inlet hole 24 connects the inner cavity 52 and the support pipe 2, the water flow flows into the inner cavity 52 through the inner water inlet hole 24, and then flows into the first fin groove 121 through the second mesh hole 51. Since the first through - hole 431 is connected to the first fin groove 121, it then enters the gap between the first mesh plate 4 and the inner return pipe 3, and finally enters the return chamber 61 and then flows out from the water outlet chamber 23. The water flow inside the temperature - regulating over - roller provided by the present utility model has two flow directions, forward flow and reverse flow, which can make the temperature of the roller surface more uniform. When cooling or heating the pole piece, it can make the temperature of the pole piece more uniform.

[0034] Since the first fin groove 121 and the second fin groove 122 are not connected, therefore, during the forward flow, when the water flow enters the second fin groove 122 and reaches the second mesh plate 51, it will not pass through the second mesh hole 51. Similarly, during the reverse flow, when the water flow enters the first fin groove 121 through the second mesh hole 51, it will not pass through the second through - hole 441.

[0035] The first mesh plate 4 and the first support part 43 are integrally formed, and the second mesh plate 5 and the second support part 44 are integrally formed. The two support parts are firmly connected to the two mesh plates respectively, which is beneficial to improving the strength.

[0036] Both the first fin groove 121 and the second fin groove 122 are provided with fins 12, increasing the density of the fins 12, making the heat dissipation more uniform.

[0037] In this embodiment, the first mesh hole 41, the third mesh hole 42, and the through - hole 431 are all square, which is convenient for matching with the square gaps of the fins 12 and improving the water - flow passing speed.

[0038] The first through hole 431 extends to the edge of the first support portion 43 close to the inner return pipe 3, and the second through hole 441 extends to the edge of the second support portion 44 close to the inner return pipe 3, increasing the areas of the two through holes, further facilitating the passage of water flow and enhancing the flow rate of the water flow.

[0039] The side water inlet pipe 6 and the first support portion 43 are arranged in a mutually offset manner, and they are connected to different parts of the first mesh plate 4. The acting forces of the two on the first mesh plate 4 are relatively dispersed, preventing the first mesh plate 4 from being damaged.

[0040] A fixed pipe 31 is coaxially arranged inside the inner return pipe 3. The fixed pipe 31 and the inner return pipe 3 are connected by a plurality of support pieces 32, enhancing the structural strength inside the inner return pipe 3 and making the inner return pipe 3 more durable. The support pipe 2 passes through the fixed pipe 31, facilitating the fixation of the support pipe 2.

[0041] A plurality of partition chambers 33 are formed by enclosing the inner return pipe 3, the fixed pipe 31, and the plurality of support pieces 32. A plurality of first mesh holes 41 are provided on the first mesh plate 4, and the shapes of the respective first mesh holes 41 respectively correspond to the cross-sectional shapes of the respective partition chambers 33, preventing the first mesh plate 4 from hindering the outflow of the water flow inside the inner return pipe 3 and further enhancing the flow rate of the water flow.

[0042] There are two inner water inlet holes 24, two water outlet holes 26, and two inner water inlet pipes 25 that are relatively arranged. When the water flow flows through the inner water inlet pipe 25 into the inner cavity 52, since there are two inner water inlet holes 24 and the two inner water inlet holes 24 are relatively arranged, the water flow is divided into two opposite-flowing strands, which can evenly and quickly fill all parts of the inner cavity 52. Similarly, when the water flow flows through the water outlet holes 26 into the water outlet cavity 23, it can evenly and quickly fill all parts of the water outlet cavity 23. Similarly, when the water flow flows through the inner water inlet pipe 25 into the slit cavity 62, it can evenly and quickly fill all parts of the slit cavity 62.

[0043] A support plate 63 is connected to one end of the side water inlet pipe 6 close to the side plate 11, which is beneficial to enhancing the structural strength of the side water inlet pipe 6. And when assembling the side water inlet pipe 6 and the support pipe 2, the support plate 63 can play a positioning role, facilitating the assembly.

[0044] Both ends of the support pipe 2 respectively protrude from the two side plates 11, facilitating the fixation of both ends of the support pipe 2, thereby facilitating the use of this temperature-adjusting roller.

[0045] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
