[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] In actual use, traditional chillers use cooling devices that directly cool the chiller compressor with a fan. The compressor itself may lack an effective heat dissipation structure and have a small heat dissipation area, making it difficult to dissipate heat to the surrounding environment and thus failing to achieve the ideal cooling effect.
[0021] In view of this, the present invention provides a cooling device for a chiller, which solves the problem that in actual use, traditional chiller cooling devices directly cool the chiller compressor with a fan, and the compressor itself may lack an effective heat dissipation structure and have a small heat dissipation area, making it difficult to dissipate heat to the surrounding environment and thus failing to achieve the ideal cooling effect.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Example 1: By Figure 1-4 It is known that a cooling device for a chiller includes a cooling box 1, a heat dissipation vent 11 on the upper part of the outer wall of the cooling box 1, an air inlet 12 on the lower part of the outer wall of the cooling box 1, a fan 14 fixedly connected to the inner wall of the cooling box 1, and a compressor 3 disposed above the fan 14. The cooling device for the chiller also includes a fixing device 4, a cleaning device 5, and a heat absorption device 6. The fixing device 4 is disposed on the top of the compressor 3; the cleaning device 5 is disposed on the side of the air inlet 12; and the heat absorption device 6 is disposed on the outer wall of the cooling box 1. The fixing device 4 increases the heat dissipation area of the outer wall of the compressor 3, the cleaning device 5 cleans the filter screen installed on the air inlet 12, and the heat absorption device 6 absorbs the heat generated by the fan 14.
[0024] In the specific implementation process, it is worth noting that the cooling box 1 is shaped like a quadrangular prism with an open top. The compressor 3 is placed inside the cooling box 1 through the opening at the top. Heat dissipation vents 11 are provided on the upper sides and front and back of the outer wall of the cooling box 1 to assist in heat dissipation of the compressor 3. Air inlets 12 are also provided on the lower sides and front and back of the outer wall of the cooling box 1. The air inlets 12 and heat dissipation vents 11 form an air circulation channel. Filters are installed on the surfaces of both the heat dissipation vents 11 and the air inlets 12 to prevent foreign objects from entering the interior of the cooling box 1 and damaging the equipment. The fan 14 consists of fan blades and a frame. The fan blades can be made of aluminum alloy, and the frame can also be selected based on heat dissipation efficiency. The high-quality aluminum alloy material can more quickly transfer the heat generated by the fan 14 to the inner wall of the cooling box 1. In conjunction with the external heat absorption device 6, the heat of the inner wall of the cooling box 1 is absorbed to ensure the normal operation of the fan 14. The compressor 3 can be selected according to the actual needs of the chiller, as long as it meets the working requirements. For example, a scroll compressor can be used. The top of the compressor 3 is the input end and the bottom is the output end. The operator increases the heat dissipation area of the outer wall of the compressor 3 by fixing device 4, and cleans the filter screen installed on the air inlet 12 by cleaning device 5. The heat generated by the fan 14 can also be absorbed by the heat absorption device 6 to ensure the normal operation of the chiller.
[0025] Furthermore, the bottom of the compressor 3 is attached to a bracket 13, which is fixedly connected to the inner wall of the cooling box 1 and located above the fan 14. The top of the compressor 3 is fixedly connected to a connecting seat 31, and the side wall of the compressor 3 is fixedly connected to a mounting groove 32. The bottom of the compressor 3 is connected to a conveying pipe 33, and the end of the conveying pipe 33 passes through the side wall of the cooling box 1. The fixing device 4 includes a fixing clip 41, a bolt 42, a fixing seat 43, and a heat dissipation fin 44. The fixing clip 41 is rotatably connected to the top of the connecting seat 31 by a pin. Bolt 42 is threadedly connected to the inner wall of fixing clip 41; fixing seat 43 is rotatably connected to the bottom of bolt 42 through a sealed bearing, and its outer wall is inserted into the inner wall of mounting groove 32; heat dissipation fins 44 are slidably engaged with the inner wall of mounting groove 32, the top of heat dissipation fins 44 is pressed against the bottom of fixing seat 43, and the side of the top of heat dissipation fins 44 away from fixing seat 43 is pressed against the bottom of fixing clip 41; wherein, through the cooperation of fixing clip 41, bolt 42, fixing seat 43 and heat dissipation fins 44, the heat dissipation area of compressor 3 is increased;
[0026] In the specific implementation process, it is worth noting that the cross-section of the bracket 13 is I-shaped, and when viewed from above, it is cross-shaped, serving to support and fix the compressor 3. Multiple connecting seats 31 are provided, forming a U-shape. The appropriate number can be selected according to the needs of the cooling device and fixedly connected to the top of the compressor 3. The number of mounting slots 32 corresponds one-to-one with the number of connecting seats 31. Both are auxiliary for the installation of the heat dissipation fins 44. The conveying pipe 33 is used to transport the medium processed by the compressor 3 to the outside of the cooling box 1. Both the connecting seats 31 and the fixing clips 41 can be made of aluminum alloy. The fixing clip 41 is L-shaped, with one end rotatably connected to the connecting seat 31 via a pin, and the other end used to abut against the heat dissipation fins 44. A threaded hole is provided on its top for use with bolts 42. The bolts 42 can be made of the same material as the fixing clips 41. The fixing seat 43… The overall shape is 'T', with a cylinder at the top and a square prism at the bottom. The square prism at the bottom fits completely against the inner wall of the mounting groove 32. The heat dissipation fins 44 are rectangular plates, and their material can be aluminum, which has good thermal conductivity, or copper. The cross-section of the heat dissipation fins 44 is 'T' shaped, and the part located inside the mounting groove 32 fits completely against the inner wall of the mounting groove 32 to ensure heat conduction and heat dissipation. It can be understood that the number of fixing clips 41, bolts 42, fixing seats 43, and heat dissipation fins 44 is the same as that of the mounting groove 32 and the connecting seat 31. The number is not limited and can be added according to the actual heat dissipation needs to ensure the cooling effect of the cooling device. By cooperating with the fixing clips 41, bolts 42, fixing seats 43, and heat dissipation fins 44, the heat dissipation area of the compressor 3 is increased, thereby improving the cooling effect of the cooling device for the chiller.
[0027] Furthermore, two storage boxes 15 are provided on both sides of the air inlet 12. The cleaning device 5 includes a limiting rod 51, a spring 52, a connecting rod 53, and a cleaning brush 54. There are two limiting rods 51, which are fixedly connected to the inner walls of the two storage boxes 15 respectively. There are two springs 52, which are respectively sleeved on the outer walls of the two limiting rods 51, and their bottoms are fixedly connected to the bottom of the inner walls of the two storage boxes 15 respectively. The two ends of the connecting rod 53 are respectively sleeved on the outer walls of the two limiting rods 51, and their bottom sides are fixedly connected to the tops of the two springs 52 respectively. The cleaning brush 54 is fixedly connected to the outer wall of the connecting rod 53 on the side close to the cooling box 1. The filter screen installed on the surface of the air inlet 12 is cleaned by the cooperation of the limiting rod 51, spring 52, connecting rod 53, and cleaning brush 54.
[0028] In the specific implementation process, it is worth noting that there are eight storage boxes 15, two on each of the front, back, left, and right sides of the cooling box 1, corresponding to the air inlet 12. The interior of each box is hollow, and the sealing cover is fixed to the front of the storage box 15 with screws. The material of the sealing cover can be stainless steel. The limiting rod 51 is rod-shaped, made of stainless steel with a smooth surface, and its top and bottom are fixed to the top and bottom of the inner wall of the storage box 15, respectively. The spring 52 is made of carbon spring steel, and its elastic coefficient is selected according to actual needs, as long as it meets the operational requirements. The spring 52 and the limiting rod... The number of positioning rods 51 is the same as the number of cargo boxes 15. There are four connecting rods 53, which are square rods in general. An auxiliary plate is provided on the side away from the cooling box 1. The cleaning brush 54 is fixedly installed on the side of the connecting rod 53 near the cooling box 1. Its material can be selected according to actual needs, such as nylon. There are also four cleaning brushes 54. The staff can clean the filter screen installed on the surface of the air inlet 12 by using the cooperation of the limiting rods 51, springs 52, connecting rods 53 and cleaning brushes 54, which improves the service life of the cooling device for the chiller.
[0029] Specifically, the operator places the compressor 3 for the chiller inside the cooling box 1, connecting its bottom output end to the top of the delivery pipe 33. The chiller is then started, and as it operates, the matching compressor 3 begins to generate heat. When the chiller's cooling device is needed, the operator activates the fan 14 via an external controller. The fan 14 draws outside air into the cooling box 1 through the air inlet 12, blowing air onto the compressor 3 to cool it. If the cooling effect is insufficient, the operator rotates the bolt 42 counterclockwise. The bolt 42 moves the fixing seat 43 away from the mounting slot 32. Then, the fixing clip 41 is rotated using a pin to move it away from the mounting slot 32. The heat dissipation fins 44 are then removed and inserted into the mounting slot 32. Finally, the fixing clip 41 and bolt 42 are returned to their original positions. At this point, the heat dissipation fins 44 are fixed to the outside of the compressor 3. The compressor 3 transfers heat to the heat dissipation fins 44. The air blown by the fan 14 comes into contact with the heat dissipation fins 44 and carries away the heat, achieving the purpose of cooling the compressor 3. After long-term use, when the filter screen on the air inlet 12 is found to be blocked by foreign objects, the operator can step on the auxiliary plate on the side wall of the connecting rod 53 and exert force downwards. The connecting rod 53 moves downwards, compressing the spring 52 and driving the cleaning brush 54 to move downwards. The cleaning brush 54 cleans the foreign objects attached to the surface of the filter screen of the air inlet 12. When the cleaning brush 54 passes the filter screen from top to bottom, the foot can be released. At this time, the pressure on the top of the connecting rod 53 disappears, the spring 52 rebounds, and pushes the connecting rod 53 back to its original position. The connecting rod 53 drives the cleaning brush 54 back to its original position. At this time, the cleaning brush 54 cleans the filter screen again, which can achieve quick cleaning. If the foot-stepping method does not work smoothly, the top of the connecting rod 53 can be pressed down by hand and moved downwards slowly to prevent jamming.
[0030] Example 2: From Figure 1-4 It is known that the heat absorption device 6 includes a protective cover 61 and a heat absorption pipe 62. The protective cover 61 is fixedly connected to the outer wall of the cooling box 1 and is located below the conveying pipe 33. The heat absorption pipe 62 is disposed inside the protective cover 61, and its outer wall is fixedly connected to the outer wall of the cooling box 1. Both ends of the heat absorption pipe 62 penetrate the side wall of the protective cover 61. The protective cover 61 and the heat absorption pipe 62 work together to dissipate heat from the fan 14 in operation.
[0031] In the specific implementation process, it is particularly worth noting that the overall shape of the protective cover 61 is a 'frame' shape, which is fixed around the outer wall of the cooling box 1. A protective net is installed on its side wall, which can not only protect the heat absorption pipe 62 inside it, but also help the heat absorption pipe 62 dissipate heat. There are three heat absorption pipes 62, which are fixed on the outer wall of the cooling box 1 from top to bottom in sequence. Their input ends and output ends are on one side of the cooling box 1 and can be connected to external heat absorption devices, enabling the heat absorption medium to flow inside the heat absorption pipe 62 and带走 heat. Its material can be selected as aluminum. Through the cooperation of the protective cover 61 and the heat absorption pipe 62, the staff dissipates heat from the fan 14 in the working state, ensuring the operation stability of the cooling device for the water chiller;
[0032] Further, support feet 16 are fixedly connected to the four corners of the bottom of the cooling box 1, and an anti-fouling cover 2 is fixedly connected to the top of the cooling box 1. An air outlet 21 is opened on the surface of the anti-fouling cover 2;
[0033] In the specific implementation process, it is particularly worth noting that the support feet 16 play a supporting role for the overall cooling box 1, and the anti-fouling cover 2 is used to prevent foreign objects from entering the inside of the cooling box 1 from the top of the cooling box 1 and affecting the operation of each part inside it. A filter screen is also provided on the air outlet 21, which can not only prevent foreign objects from entering the inside of the cooling box 1, but also achieve the purpose of ventilation and heat dissipation, improving the structural stability of the cooling device for the water chiller;
[0034] Specifically, when the fan 14 is running, as time goes by, the fan 14 will also generate heat. These heats are transferred to the inner wall of the cooling box 1 through the frame of the fan 14 itself. When it is necessary to cool down the fan 14, the staff connects the heat absorption pipe 62 to an external cooling medium storage device, enabling the cooling medium to flow into the inside of the heat absorption pipe 62 and flow out from the other end of the heat absorption pipe 62, realizing the medium circulation. This process absorbs the heat transferred by the fan 14 and achieves cooling;
