Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic, in particular to a cooling type graphite boat paddle. Background Art

[0002] Among solar cells, crystalline silicon solar cells have developed most rapidly. The preparation of crystalline silicon solar cells generally goes through processes such as texturing, diffusion, coating, screen printing, and sintering. The graphite boat is a carrier in the surface coating process of solar cell wafers. After the graphite boat enters the furnace tube to complete the coating process, the boat paddle, as an important part of the graphite boat pushing mechanism, needs to pull the graphite boat out of the high-temperature furnace tube and then transfer it to a cooling device for cooling. Therefore, the working environment of the boat paddle is accompanied by high temperature, low temperature, and sudden changes in high and low temperatures, which will affect the service life of the boat paddle, making it prone to breakage and increasing production costs. Content of the Utility Model

[0003] The purpose of the utility model is to provide a cooling type graphite boat paddle with an automatic cooling function, so as to improve the service life of the paddle and save costs.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A cooling type graphite boat paddle includes a fixed rod, a first support rod, and a second support rod. The first support rod and the second support rod are connected to the fixed rod through a fastener. The ends of the first support rod and the second support rod away from the fixed rod are connected through an arc tube. The first support rod and the second support rod are hollow inside. The port of the first support rod is the water inlet, and the port of the second support rod is the water outlet. The inside of the first support rod, the second support rod, and the arc tube is connected. After water is passed through the water inlet, it flows out from the water outlet through the arc tube.

[0005] As a further improved technical scheme of the utility model, a bare copper tube is hung below the fastener, and the bare copper tube is in an S-shaped multi-layer winding structure.

[0006] As a further improved technical scheme of the utility model, one end of the bare copper tube is connected to the water inlet of the first support rod, and the other end of the bare copper tube is connected to the water outlet of the second support rod.

[0007] As a further improved technical scheme of the utility model, a circulation pump is arranged between the bare copper tube and the second support rod.

[0008] As a further improved technical scheme of the utility model, a protective shell is arranged below the fastener, and the protective shell is located outside the bare copper tube.

[0009] As a further improved technical scheme of the utility model, the protective shell is a concave-shaped baffle, and the bare copper tube is located in the central concave hole thereof, with no obstruction at both ends.

[0010] As a further improved technical solution of the present utility model, the first support rod and the second support rod are arranged relatively parallel to the fixed rod, and the fixed rod is located between the first support rod and the second support rod.

[0011] As a further improved technical solution of the present utility model, at least two fasteners are arranged side by side.

[0012] As can be seen from the above technical solutions, the graphite boat paddle of the present utility model has a self-cooling function. The support rod part for supporting the graphite boat is designed to be hollow, and circulating water is passed through it for cooling and heat dissipation, saving space and having a low transformation cost. At the same time, a bare copper tube is additionally provided for further heat dissipation, avoiding reducing the service life of the paddle due to the high temperature of the graphite boat during use. Moreover, when using this paddle to take out the graphite boat, the self-cooling function can also be used to adsorb the local temperature of the graphite boat, assisting in reducing the subsequent overall cooling time of the graphite boat.

[0015] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0016] Refer to Figure 1, a cooling type graphite boat paddle according to this embodiment includes a fixing rod 1, a first support rod 2 and a second support rod 3. The first support rod 2 and the second support rod 3 are connected to the fixing rod 1 through a clamping member 4. The first support rod 2 and the second support rod 3 are arranged relatively parallel to the fixing rod 1. The fixing rod 1 is located between the first support rod 2 and the second support rod 3. The fixing rod 1 is used to connect to an external paddle driving mechanism to support the entire graphite boat paddle body. The first support rod 2 and the second support rod 3 are used to support a part of the graphite boat. The ends of the first support rod 2 and the second support rod 3 away from the fixing rod 1 are connected through an arc-shaped pipe 5. The first support rod 2 and the second support rod 3 are hollow inside and can conduct water. The port of the first support rod 2 is the water inlet 21, and the port of the second support rod 3 is the water outlet 31. The first support rod 2, the second support rod 3 and the arc-shaped pipe 4 are internally connected. After water is passed through the water inlet 21, it flows out from the water outlet 31 through the arc-shaped pipe 4. The circulating water can cool the graphite boat paddle. When the paddle takes in and out of the furnace body to pick up and place the graphite boat, the life of the paddle will not be reduced due to high temperature and other conditions. Moreover, when taking out the processed graphite boat, the local temperature of the graphite boat can also be adsorbed by its own cooling, and the overall cooling time of the graphite boat can be reduced to a certain extent.

[0017] Further combined with Figure 1 - Figure 2 , at least two clamping members 4 are arranged side by side to increase stability. A bare copper pipe 6 is hung below the clamping member 4 through a clip 7. The bare copper pipe 6 is in an S-shaped multi-layer surrounding structure. One end of the bare copper pipe 6 is connected to the water inlet 21 of the first support rod 2, and the other end of the bare copper pipe 6 is connected to the water outlet 31 of the second support rod 3. A circulation pump (not shown in the figure and does not affect understanding) is arranged between the bare copper pipe 6 and the second support rod 3. The circulation pump is connected to the water outlet 31 and the bare copper pipe 6 through a water pipe to drive the water circulation in the first support rod 2, the second support rod 3 and the bare copper pipe 6. The water passing through the bare copper pipe 6 dissipates heat. When taking the graphite boat with this graphite boat paddle, the bare copper pipe 6 does not extend into the furnace.

[0018] A protective shell 8 is also fixedly arranged below the clamping member 4. The protective shell 8 is located outside the bare copper pipe 6. The protective shell 8 is a concave stainless steel baffle. The bare copper pipe 6 is located at its central concave hole, and there is no obstruction at both ends, which is convenient for air circulation and can also protect the bare copper pipe 6 from being knocked.

It can be understood that according to the different placement positions of the product, the spatial relative position terms can be intended to include different orientations other than the orientations shown in the figure, and should not be construed as a limitation on the claims.
