The ingot cooling device 10 can cool the ingot during ingot cutting to improve ingot slicing quality.

The crystal bar cooling device 10 comprises a liquid containing box 11, a guide plate 12 and a spray pipe 13, wherein the liquid containing box 11 is provided with a containing cavity 111 and a liquid overflow port 112, the containing cavity 111 is used for storing cooling liquid, and the liquid overflow port 112 is communicated with the containing cavity 111 so that the cooling liquid in the containing cavity 111 can flow out from the liquid overflow port 112. The baffle 12 is disposed on one side of the overflow port 112. The spray pipe 13 is arranged on the upper side of the guide plate 12, and the orifice of the spray pipe 13 faces the guide plate 12. So, the overflow port 112 of the liquid containing tank 11 can overflow the cooling liquid in the liquid containing tank 11 to the guide plate 12, the spray pipe 13 can spray the cooling liquid on the guide plate 12, and the cooling liquid can flow to the crystal bar under the guidance of the guide plate 12 to cool the cut crystal bar. Specifically, the cooling liquid can flow to the position where the wire mesh contacts the ingot under the guidance of the deflector 12 to cool the temperature at the cutting position.

The crystal bar cooling device 10 can effectively increase the flow of the cooling liquid flowing to the crystal bar by overflowing liquid from the overflow port 112 and spraying liquid from the spray pipe 13, thereby improving the cooling effect and further improving the slicing quality of the crystal bar.

The spray head may communicate with the tank through a second liquid inlet pipe 15 so that the spray head sprays the cooling liquid in the tank onto the baffle 12.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular sequence and should not be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more features. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

In order to more clearly explain the structure of the liquid container 11, the structure of the liquid container 11 and the components related thereto will be specifically described below with reference to the drawings.

With continued reference to fig. 1 and 2, the tank 11 includes a bottom wall 113, a first side wall 114, a second side wall 115, a third side wall 116 and a fourth side wall 117, the first side wall 114, the second side wall 115, the third side wall 116 and the fourth side wall 117 are respectively connected to the bottom wall 113, the first side wall 114 and the second side wall 115 are oppositely disposed, the third side wall 116 and the fourth side wall 117 are oppositely disposed and respectively connected between the first side wall 114 and the second side wall 115, and the bottom wall 113, the first side wall 114, the second side wall 115, the third side wall 116 and the fourth side wall 117 together define the accommodating cavity 111.

Wherein the height of the first side wall 114 is lower than the height of the third side wall 116 and the height of the fourth side wall 117 such that the end of the first side wall 114, a portion of the third side wall 116 and a portion of the fourth side wall 117 together define the discharge opening 112. In this way, the overflow port 112 can be formed in the liquid container 11 conveniently without performing an additional perforating process, and the size of the overflow port 112 can be made as large as possible, so that the cooling liquid can flow out from the overflow port 112.

It will be appreciated that, in order to buffer the flow rate of the cooling liquid flowing out of the overflow port 112 after entering the liquid container 11, referring to fig. 3 and 4 in combination with fig. 1 and 2, fig. 3 is a schematic diagram of a second structure of the crystal bar cooling device provided in the embodiment of the present application, and fig. 4 is a cross-sectional view at A-A in fig. 3. The tank 11 further includes a first slow flow plate 16 disposed in the accommodating chamber 111, the first slow flow plate 16 is connected to the third side wall 116 and the fourth side wall 117, the first slow flow plate 16 is spaced from the bottom wall 113 to define a water flow channel 161 therebetween, the first slow flow plate 16 is spaced from the first side wall 114 to define an overflow chamber 1111 therebetween, it is understood that the accommodating chamber 111 is divided into a liquid inlet chamber 1112 and the overflow chamber 1111 by the first slow flow plate 16, the first liquid inlet tube 14 circulates the cooling liquid to the liquid inlet chamber 1112, and the cooling liquid can flow to the overflow chamber 1111 through the water flow channel 161 after being slowly flowed by the first slow flow plate 16 and then flows out from the overflow port 112.

The height of the first slow flow plate 16 is higher than the height of the first side wall 114, so that the cooling liquid in the liquid inlet cavity 1112 can flow into the overflow cavity 1111 only from the water flow channel 161, and the cooling liquid can overflow when the cooling liquid does not reach the upper end of the first slow flow plate 16, thereby playing roles of buffering the flow rate and stabilizing the flow rate.

Wherein, the nozzle 13 may be fixed at one end of the first slow flow plate 16 away from the bottom wall 113, and the first slow flow plate 16 also plays a role in supporting and fixing the nozzle 13.

In order to further buffer the flow rate of the cooling liquid, the tank 11 may further include a second flow-slowing plate 17 spaced apart from the first flow-slowing plate 16, the second flow-slowing plate 17 being connected to the bottom wall 113 and located at a side of the first flow-slowing plate 16 facing away from the first side wall 114, the second flow-slowing plate 17 dividing the liquid inlet chamber 1112 into a first space 11121 and a second space 11122, it being understood that the second flow-slowing plate 17, the second side wall 115, portions of the third side wall 116 and portions of the fourth side wall 117 together define the first space 11121, and the first flow-slowing plate 16, the second flow-slowing plate 17, portions of the third side wall 116 and portions of the fourth side wall 117 together define the second space 11122, the second space 11122 being in communication with the overflow chamber 1111 through the water flow channel 161.

Wherein the height of the second slow flow plate 17 is equal to or higher than the height of the first side wall 114 and lower than the height of the first slow flow plate 16. In this way, the first liquid inlet pipe 14 circulates the cooling liquid to the first space 11121 of the liquid inlet cavity 1112, the cooling liquid can be slowly flowed by the second slow flow plate 17, after the cooling liquid fills the first space 11121, overflows into the second space 11122 from the upper end of the second slow flow plate 17, and the cooling liquid entering the second space 11122 is slowly flowed by the first slow flow plate 16, flows to the overflow cavity 1111 through the water flow channel 161, and flows out from the overflow port 112.

It should be noted that the cooling liquid flowing out from the overflow port 112 may flow onto the ingot through the baffle 12, specifically, the cooling liquid may flow to a position where the wire mesh contacts the ingot under the guidance of the baffle 12, so as to cool the temperature at the cutting position. Because the contact position of the wire net and the crystal bar is not always at a fixed position and sometimes is deviated, if the flow guide direction of the guide plate 12 cannot be adjusted, the cooling liquid cannot flow to the contact position of the wire net and the crystal bar, so that the contact position of the wire net and the crystal bar cannot be cooled to the greatest extent, the waste of the cooling liquid is caused, and even the cutting quality is affected.

The fourth connecting portion 123 is connected to a side of the guiding body 121 facing the second connecting portion 1171, and is rotatably connected to the second connecting portion 1171. In this way, the diversion body 121 and the liquid container 11 can be rotationally connected, so that the angle adjusting device 18 can drive the diversion body 121 to rotate to adjust the diversion direction of the diversion body 121.

Referring to fig. 4 to 6, in order to enable the guide body 121 to rotate better, an end of the guide body 121 close to the first sidewall 114 is disposed at an interval from the first sidewall 114 to form a clearance 124, so that the guide body 121 does not interfere with the first sidewall 114 during the rotation of the guide body 121, and the guide body 121 can perform angle adjustment more smoothly.

The crystal bar cooling device 10 may further include a flexible connecting piece 19, wherein one end of the flexible connecting piece 19 is connected to the first side wall 114, and the other end of the flexible connecting piece 19 is connected to one end of the guiding body 121 near the first side wall 114, so as to close a clearance gap 124 between the guiding body 121 and the first side wall 114. In this way, the flexible connecting piece 19 does not obstruct the rotation of the diversion body 121, and can prevent the cooling liquid flowing out from the overflow port 112 from flowing out from the avoidance gap 124, so that the cooling liquid is better drained to the diversion body 121, and leakage is effectively prevented.

Illustratively, the flexible connector 19 may be a rubber sheet, which may be fixedly connected to the first sidewall 114 and the flow guiding body 121 by means of fusion bonding.
