Description

Technical Field

[0001] The utility model belongs to the technical field of ingot casting equipment, and in particular relates to a heat dissipation device and ingot casting equipment. Background Art

[0002] The ingot casting furnace is a key equipment for producing polysilicon in the photovoltaic industry. It adjusts and slices silicon through melting and directional crystal growth solidification technology to make it a material that meets the production requirements of photovoltaic cells. The existing ingot casting furnace generally needs to be cooled by filling with high-purity argon gas when it is shut down. The specific operation is: after the furnace is shut down, argon gas needs to be continuously passed into the furnace for 5 hours, and the inside of the ingot casting furnace is cooled by the circulation of argon gas; after the furnace is shut down, the pump body in the ingot casting furnace cannot be turned off either, and the pump body needs to continue working for 5 hours. During the operation, the pump body draws out the gas in the furnace, circulates the argon gas in the furnace, and then cools the inside of the ingot casting furnace. Therefore, the shutdown time is at least more than 10 hours.

[0003] The long-term operation of the pump during the shutdown process will consume a lot of electricity, increase the ingot casting cost, and affect the life of the pump or parts. In addition, although the argon recovery rate is very high when argon is continuously passed into the furnace for 5 hours, the continuous passage of argon will also increase the ingot casting cost. Due to the difference in the thermal insulation of the ingot casting furnace, when the temperature cannot be completely lowered under the above conditions, if the furnace is dismantled directly, the ingot casting furnace will explode due to the over-high temperature, which will further greatly increase the ingot casting cost. Dismantling the furnace after the shutdown for 10 hours also wastes a lot of time, which seriously affects the ingot casting output.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0034] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings.

[0035] Embodiment 1:

[0036] Reference Figure 1 As shown, the heat dissipation device in this embodiment includes a hollow base 1 and a liquid cooling tube 2 fixedly installed on the base 1, a receiving space 200 is formed between the base 1 and the liquid cooling tube 2, the liquid cooling tube 2 includes a liquid inlet end 21 and a liquid outlet end 22 penetrating the base 1, the heat dissipation device also includes a liquid inlet pipe 3 and a liquid outlet pipe 4, the liquid inlet pipe 3 is connected to the liquid inlet end 21, and the liquid outlet pipe 4 is connected to the liquid outlet end 22.

[0037] According to this design, coolant can be introduced into the liquid cooling pipe 2 to keep the liquid cooling pipe 2 in a low temperature state, so as to facilitate heat exchange with the external structure, thereby reducing the temperature of the external structure. When the heat dissipation device is combined with the ingot casting furnace, after the furnace is stopped, the coolant is introduced into the liquid cooling pipe 2 of the heat dissipation device to realize the liquid cooling cycle. The heat dissipation device exchanges heat with the ingot casting furnace after the furnace is stopped, takes away the heat in the furnace, and dissipates the temperature in the ingot casting furnace quickly. By using the heat dissipation device, the shutdown time can be shortened, the cooling speed can be accelerated, the life of the ingot casting furnace can be increased, the ingot casting cost can be reduced, and the ingot casting output can be increased.

[0038] Preferably, in order to enhance the heat dissipation effect of the heat dissipation device, refer to Figure 1 As shown, the heat dissipation device in this embodiment further includes a first fin 21 , and the outer wall of the first fin 21 abuts against the inner wall of the liquid cooling tube 2 .

[0039] Preferably, in order to enhance the heat dissipation effect of the heat dissipation device, refer to Figure 1 As shown, the heat dissipation device in this embodiment further includes a second fin 22 , and the inner wall of the second fin 22 abuts against the outer wall of the liquid cooling tube 2 .

[0040] Reference Figure 2 As shown, a quick-change structure 5 is installed between the liquid inlet end 21 and the liquid inlet pipe 3 and between the liquid outlet end 22 and the liquid outlet pipe 4 in this embodiment. The quick-change structure 5 includes a first quick-change pipe 51 and a second quick-change pipe 52 that are detachably connected. The first quick-change pipe 51 is connected to the liquid inlet end 21 or the liquid outlet end 22, and the second quick-change pipe 52 is connected to the liquid inlet pipe 3 or the liquid outlet pipe 4. According to this design, the liquid inlet end 21 and the liquid inlet pipe 3 and the liquid outlet end 22 and the liquid outlet pipe 4 can be removed through the quick-change structure 5, so that after a period of use, the inside of the liquid cooling pipe 2 can be cleaned and dirt can be removed to prevent the increase of dirt in the liquid cooling pipe 2 from causing blockage, which ultimately causes the cooling liquid to be unable to circulate.

[0041] Reference Figure 3 As shown, in this embodiment, one of the first quick-change tube 51 and the second quick-change tube 52 is provided with a locking groove 511, and the other is provided with a locking piece 521 arranged radially and matched with the locking groove 511. When the first quick-change tube 51 and the second quick-change tube 52 are connected, the locking piece 521 is locked in the locking groove 511, and when the first quick-change tube 51 and the second quick-change tube 52 are separated, the locking piece 521 is separated from the locking groove 511. According to this design, the first quick-change tube 51 and the second quick-change tube 52 can be quickly installed and removed.

[0042] Specifically, refer to Figure 3 As shown, in this embodiment, a mounting cavity 5200 is provided in the second quick-change tube 52, a through hole 520 communicating with the mounting cavity 5200 is provided on the second quick-change tube 52, a locking groove 511 is provided on the first quick-change tube 51, a locking member 521 is provided on the second quick-change tube 52, the locking member 521 includes an elastic member 5211 and a locking block 5212 penetrating the through hole 520 and cooperating with the locking groove 511, the elastic member 5211 respectively abuts against the locking block 5212 and the inner wall of the second quick-change tube 52, and the elastic member 5211 has a tendency to make the locking block 5212 move toward the locking groove 511. According to this design, when the first quick-change tube 51 and the second quick-change tube 52 are connected, the locking block 5212 is locked in the locking groove 511, and the elastic member 5211 can prevent the locking block 5212 from being separated from the locking groove 511. When the first quick-change tube 51 and the second quick-change tube 52 are separated, the locking block 5212 has a tendency to move outward, the elastic member 5211 is compressed, and the locking block 5212 is separated from the locking groove 511. Among them, the elastic member 5211 is an elastic member. Of course, the present application is not limited to this, and the elastic member 5211 can also be a structure such as an airbag or a shrapnel.

[0043] Preferably, in order to facilitate separation of the first quick-change tube 51 and the second quick-change tube 52, Figure 4 As shown, the locking block 5212 can have a tendency to move away from the locking groove 511. In this embodiment, a guide surface 523 is provided on the locking groove 511 and / or the locking block 5212. The guide surface 523 is used to convert the axial movement between the first quick-change tube 51 and the second quick-change tube 52 into a movement of the locking member 521 radially away from the locking groove 511, so that the locking member 521 is separated from the locking groove 511. The guide surface 523 in this embodiment includes at least one of a plane and a curved surface.

[0044] For example, refer to Figure 4 As shown, the locking groove 511 in this embodiment is spherical, and the locking block 5212 is spherical. The radius of the locking block 5212 is slightly smaller than the radius of the locking groove 511. When the first quick-change tube 51 and the second quick-change tube 52 are connected, the locking block 5212 is locked in the locking groove 511 and part of the outer surface of the locking block 5212 abuts against the inner wall of the locking groove 511. When the first quick-change tube 51 and the second quick-change tube 52 are separated, the locking block 5212 is separated from the inner wall of the locking groove 511, and part of the locking block 5212 is accommodated in the installation cavity 5200, and the other part is accommodated in the through hole 520.

[0045] Of course, the present application is not limited to this. In other embodiments, the locking groove 511 or the locking block 5212 may be provided with a guide plane, or a combination of a plane and a curved surface; or, the locking groove 511 and the locking hole are both provided with mutually matching guide planes or a combination of a plane and a curved surface.

[0046] In order to limit the depth of the first quick-change tube 51 extending into the second quick-change tube 52, refer to Figure 3 As shown, in this embodiment, the first quick-change tube 51 is provided with a first protrusion 512 on the outside, and the first protrusion 512 abuts against the second quick-change tube 52, that is, the first protrusion 512 and the upper end surface of the second quick-change tube 52 abut against each other. The second quick-change tube 52 is provided with a second protrusion 522 on the inside, and the second protrusion 522 abuts against the first quick-change tube 51, that is, the second protrusion 522 abuts against the lower end surface of the first quick-change tube 51. According to this design, the relative displacement of the first quick-change tube 51 and the second quick-change tube 52 can be limited along the axial direction of the quick-change structure 5, so as to avoid the first quick-change tube 51 from excessively penetrating into the second quick-change tube 52, which causes the locking member 521 to separate from the locking groove 511.

[0047] Of course, the present application is not limited to this. When only the first protrusion 512 is provided on the outside of the first quick-change tube 51, and the first protrusion 512 abuts against the second quick-change tube 52; or when only the second protrusion 522 is provided on the inside of the second quick-change tube 52, and the second protrusion 522 abuts against the first quick-change tube 51, the same technical effect can be achieved.

[0048] Preferably, the liquid inlet pipe 3 and the liquid outlet pipe 4 in this embodiment are both provided with a temperature detection device and a flow detection device. According to this design, the temperature and flow of the coolant can be detected in real time, and an alarm can be given when an abnormality occurs; moreover, the temperature inside the ingot furnace can be reflected by the temperature of the coolant, and the furnace cover can be opened when the coolant temperature drops to a reasonable temperature, which can prevent personnel from blindly opening the furnace cover without knowing the temperature inside the furnace, causing the ingot furnace to explode.

[0049] Of course, the present application is not limited thereto, and in other embodiments, a temperature detection device may be provided only on the liquid inlet pipe 3 or the liquid outlet pipe 4, or a flow detection device may be provided only on the liquid inlet pipe 3 or the liquid outlet pipe 4.

[0050] Embodiment 2:

[0051] Reference Figure 5 to Figure 7 As shown, the ingot casting equipment in this embodiment includes an ingot casting furnace 9 and a heat dissipation device 100 shown in the first embodiment. The ingot casting furnace 9 includes a furnace bottom 91, a solid felt 92 fixedly mounted on the furnace bottom 91, and a heat preservation tube 93 fixedly mounted on the solid felt 92. The heat preservation tube 93 is at least partially located in the receiving space 200 of the heat dissipation device 100. The heat dissipation device 100 is detachably mounted on the solid felt 92. The liquid inlet pipe 3 and the liquid outlet pipe 4 of the heat dissipation device 100 both penetrate the solid felt 92 and the furnace bottom 91. Among them, two first through holes 921 are provided on the solid felt 92, and two second through holes 911 are provided on the furnace bottom 91. The two first through holes 921 completely coincide with or substantially coincide with the axes of the corresponding two second through holes 911.

[0052] Among them, refer to Figure 8 As shown, the solid felt 92 is provided with two first through holes 921 through which the liquid inlet end 21 and the liquid outlet end 22 can pass respectively, and the liquid inlet pipe 3 and the liquid outlet pipe 4 are respectively connected to the liquid inlet end 21 and the liquid outlet end 22 through two second through holes 911 on the furnace bottom 91.

[0053] Preferably, when the heat dissipation device 100 has a quick-change structure 5, the first quick-change tube 51 of the quick-change structure 5 is passed through the first through hole 921, and the second quick-change tube 52 is fixedly installed in the second through hole 911. When the heat dissipation device 100 needs to be disassembled, the heat dissipation device 100 is lifted to separate the first quick-change tube 51 and the second quick-change tube 52, thereby separating the heat dissipation device 100 from the ingot furnace 9.

[0054] According to this design, after the furnace is shut down, coolant is passed through the liquid cooling pipe 2 of the heat dissipation device 100 to realize liquid cooling circulation. The heat dissipation device 100 exchanges heat with the ingot furnace 9 after the furnace is shut down, takes away the heat in the furnace, and quickly dissipates the temperature in the ingot furnace. Therefore, after using the heat dissipation device 100, the shutdown time can be shortened, the cooling speed can be accelerated, the life of the ingot furnace 9 can be increased, the ingot casting cost can be reduced, and the ingot casting output can be increased.

[0055] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0056] The utility model provides a heat dissipation device and ingot casting equipment. Liquid cooling circulation is achieved by passing coolant into the liquid cooling pipe of the heat dissipation device.
