Abstract

The present invention discloses an air-cooled chiller, which is provided with a heat dissipation mechanism, which consists of a plurality of main heat dissipation boxes. The airflow passes through the main heat dissipation channel and exchanges heat with the refrigerant in the main heat dissipation box. Compared with the prior art that the fins are thin and easy to be damaged, the system composed of the main heat dissipation box and the main heat dissipation channel is more stable and not easy to be damaged, and the problem of reduced heat dissipation effect caused by damage to the heat dissipation components is reduced; a telescopic tube, an auxiliary heat dissipation box and an auxiliary heat dissipation channel are also provided, and the auxiliary heat dissipation box is added between the main heat dissipation boxes to increase the flow path of the refrigerant, so that the refrigerant can be cooled more fully. Compared with the prior art that needs to purchase a new fin-type radiator to meet the cooling demand, the present application only needs to install the auxiliary heat dissipation box, which has low cost and is more conducive to user use. The auxiliary heat dissipation box can be disassembled and stored when not needed, and is flexible to use.

Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to an air-cooled chiller. Background Art

[0002] A chiller is a machine that cools water at room temperature to the temperature that users need to use. The chiller mainly includes a refrigerant circulation system, a water circulation system and an electrical automatic control system. The refrigerant circulation system and the water circulation system both include an evaporator. The liquid refrigerant and the circulating water exchange heat in the evaporator. The refrigerant absorbs the heat of the circulating water and reduces the circulating water to a suitable temperature for discharge. At this time, the liquid refrigerant absorbs heat and becomes gaseous. It is sucked into the cooling component by the compressor for cooling. After cooling, it flows back to the evaporator to absorb heat again. The cooling effect is achieved by repeating the cycle. If the cooling component uses a condenser (such as a shell and tube condenser) and cold water is passed through to cool the refrigerant and liquefy it, it is a water-cooled chiller. If the cooling component uses a radiator (such as a finned radiator), the fan forms an airflow to cool the refrigerant and liquefy it, it is an air-cooled chiller.

[0003] The existing air-cooled chiller forms a V-shape by combining two finned radiators. A fan is set at the top of the frame, that is, at the V-shaped opening, to drive the airflow through the finned radiator. Although this method can achieve a cooling effect, the fins of the finned radiator are thin and light. After long-term use or when the airflow is large, the fins are easily damaged, which leads to a decrease in the heat dissipation effect. Summary of the invention

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The heat dissipation mechanism is composed of several main heat dissipation boxes. The airflow passes through the main heat dissipation channel and exchanges heat with the refrigerant in the main heat dissipation box. Compared with the thin and easy-to-damage fins in the prior art, the system composed of the main heat dissipation box and the main heat dissipation channel is more stable and less prone to damage, reducing the problem of reduced heat dissipation effect due to damage to heat dissipation components;

[0027] 2. A telescopic tube, an auxiliary heat sink and an auxiliary heat sink channel are provided. By adding an auxiliary heat sink between the main heat sinks, the refrigerant flow path is improved, so that the refrigerant can be cooled more fully. Compared with the prior art, a new finned radiator needs to be purchased to meet the cooling demand.

Moreover, the auxiliary heat sink can be disassembled and stored when not needed, which is flexible to use.

[0028] 3. A cooling mechanism is provided, and the first wiping block moves along the wind receiving plane to wipe the wind receiving plane, thereby reducing dust adhesion and avoiding the reduction of heat exchange efficiency caused by dust adhesion. In addition, compared with the existing finned radiator which is inconvenient to wipe and the fins are easily damaged during wiping, the main radiator and the auxiliary radiator are more stable in structure and not easy to be damaged, thereby increasing the service life of the product;

[0029] 4. A wetting component is provided to transport water to the water storage channel of the cooling mechanism, and then to the first wiping block through the drainage holes. On the one hand, it is easier to wipe off the dust on the wind-receiving surface, and on the other hand, some water stains will remain on the wind-receiving surface. When the airflow blows enough, the water stains are converted into gaseous water to absorb heat, further improving the heat dissipation efficiency of the main heat sink;

[0030] 5. A cleaning mechanism is provided, and the inner wall of the main heat dissipation channel and the auxiliary heat dissipation channel is cleaned by the second wiping block to reduce dust adhesion and avoid the reduction of heat exchange efficiency caused by dust adhesion. In addition, the transmission structure of the worm gear is used to reduce the speed and increase the torque, and the thread of the second screw and the worm gear is matched, so that the second wiping block can rotate while moving along the main heat dissipation channel or the auxiliary heat dissipation channel, and the cleaning is more thorough;

[0031] In summary, the inner walls of the main heat dissipation channel and the auxiliary heat dissipation channel are cleaned by the cleaning mechanism, the cooling mechanism cleans the windward surface and retains water stains, and the main heat dissipation box and the main heat dissipation channel have stable structures and are not easily damaged. Compared with the fins in the prior art that are easily damaged, the present invention has a stable structure that is not easily damaged, is easy to clean and has no dust adhesion, thereby ensuring that the heat dissipation mechanism has continuous and efficient heat dissipation efficiency.

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0059] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0060] Please refer to Figure 1 to Figure 14 The embodiment of the present invention provides an air-cooled chiller, comprising a frame 1, wherein the frame 1 is provided with a bottom frame 11, a middle frame 12 and a top frame 13 from bottom to top, wherein a compressor 14 and an evaporator 15 are provided at the top of the bottom frame 11, and the chiller comprises two heat dissipation mechanisms 2, wherein the two heat dissipation mechanisms 2 have wind receiving planes at their mutually close ends, wherein the two wind receiving planes form a V shape, wherein the normal direction of one wind receiving plane is a first direction, and the corresponding heat dissipation mechanism 2 comprises:

[0061] A plurality of main heat dissipation components 3 are evenly arranged along the second direction, including a main heat dissipation box 31, and a plurality of main heat dissipation channels 33 that penetrate the main heat dissipation box 31. The extension direction of the main heat dissipation box 31 is the third direction, and the extension direction of each main heat dissipation channel 33 is the first direction. The main heat dissipation box 31 has a wind receiving surface near another heat dissipation mechanism 2 along the first direction, and the wind receiving plane is formed by the wind receiving surfaces of all the main heat dissipation components 3. The main heat dissipation box 31 is provided with a first mounting tube 34 and a second mounting tube 38 on both sides along the third direction, respectively. The top of the main heat dissipation box 31 is connected to the first mounting tube 34, and the bottom of the main heat dissipation box 31 is connected to the second mounting tube 38. The first direction, the second direction and the third direction are perpendicular to each other; the second direction is Figure 1 The tilt direction of the heat dissipation mechanism 2, that is, Figure 4 and Figure 5 The up and down directions in the third direction are Figure 1 The front-to-back direction, that is Figure 4 and Figure 5 The left and right direction in .

[0062] The air inlet passage 22 is formed by the internal combination of all the first mounting tubes 34, the top end of which is provided with a first blocking member 21, and the bottom end of which is connected to the air outlet of the compressor 14;

[0063] The liquid return channel 23 is formed by the internal combination of all the second mounting tubes 38, the top end of which is provided with a first blocking member 21, and the bottom end is connected to the refrigerant inlet of the evaporator 15. The compressor 14 drives the refrigerant to enter each main heat dissipation box 31 along the air inlet channel 22, and then flows back to the liquid return channel 23 and flows into the evaporator 15; Figure 2 and Figure 3 As shown, an air intake tee 24 is provided at the top of the compressor 14, and the other two openings of the air intake tee 24 are connected to an air intake main pipe 25. The other end of the air intake main pipe 25 is connected to the air intake channel 22 of the corresponding heat dissipation mechanism 2, and a liquid return main pipe 26 connected to the liquid inlet of the evaporator 15 is provided at the bottom end of the liquid return channel 23, which is used to return the liquid refrigerant to the evaporator 15 for reuse.

[0064] like Figure 1 As shown, the heat dissipation mechanism 2 is composed of a plurality of main heat dissipation boxes 31. The airflow passes through the main heat dissipation channel 33 and performs heat exchange with the refrigerant in the main heat dissipation box 31. Compared with the thin and easy-to-damage fins in the prior art, the system composed of the main heat dissipation box 31 and the main heat dissipation channel 33 is more stable and less prone to damage, thereby reducing the problem of reduced heat dissipation effect due to damage to the heat dissipation components.

[0065] like Figure 5As shown, an air intake branch pipe 35 is provided at one end of the top of the main heat sink 31, and the air intake branch pipe 35 is connected to the first mounting pipe 34 and the inside of the main heat sink 31, and a second reinforcing rod 39 is provided at the other end of the top of the main heat sink 31, and the second reinforcing rod 39 is connected to the second mounting pipe 38, and a first reinforcing rod 37 is provided at one end of the bottom of the main heat sink 31, and the other end of the first reinforcing rod 37 is connected to the first mounting pipe 34, and the stability of the main heat sink 31 during operation is improved by the first reinforcing rod 37 and the second reinforcing rod 39; in addition, a second connecting pipe 311 connected to the main heat sink 31 is provided at the end of the bottom of the main heat sink 31 away from the first reinforcing rod 37, and a first connecting pipe 310 connected to the second mounting pipe 38 is provided at the position of the second connecting pipe 311 corresponding to the second connecting pipe 310, and optionally, the first connecting pipe 310 and the second connecting pipe 310 are connected to the second connecting pipe 310. A connecting pipe 312 is connected between the connecting pipes 311 through a flange, which is used to connect the first connecting pipe 310 and the second connecting pipe 311 to ensure that the main heat dissipation box 31 is connected to the inside of the second mounting pipe 38; further, two first baffles 32 are arranged and distributed along the second direction inside the main heat dissipation box 31, and the extension direction of the first baffle 32 is the third direction. The refrigerant enters the main heat dissipation box 31 along the air intake branch pipe 35, first flows along one of the first baffles 32 and the top wall of the main heat dissipation box 31, then flows along between the two first baffles 32, and finally flows along the other first baffle 32 and the bottom wall of the main heat dissipation box 31, and finally flows out from the second connecting pipe 311, thereby increasing the flow path of the refrigerant, avoiding the refrigerant from directly flowing out after flowing into the main heat dissipation box 31, and improving the heat dissipation effect.

[0066] In some embodiments, each main heat dissipation assembly 3 further includes two telescopic tubes 36, which are detachably mounted on the bottom end of the first mounting tube 34 and the bottom end of the second mounting tube 38, respectively, and the two telescopic tubes 36 are detachably connected to the top end of the first mounting tube 34 and the top end of the second mounting tube 38 of another main heat dissipation assembly 3, respectively;

[0067] The bottom of each main heat dissipation box 31 is connected to the second installation pipe 38 through the auxiliary heat dissipation component 4, and the auxiliary heat dissipation component 4 is used to dissipate heat from the refrigerant.

[0068] like Figure 3 , Figure 4 As shown, the refrigerant is cooled by the auxiliary heat dissipation component 4, and the heat dissipation path of the refrigerant is extended, so that the refrigerant can be cooled more fully. In addition, by setting the telescopic tube 36, the distance between adjacent main heat dissipation components 3 is increased, which facilitates the insertion of the auxiliary heat dissipation component 4. Optionally, because it is a telescopic tube 36, the auxiliary heat dissipation component 4 can also be directly disassembled, and the telescopic tube 36 can be compressed to reduce the distance between adjacent main heat dissipation components 3. It can be disassembled less frequently and is more flexible to use.

[0069] In some embodiments, the auxiliary heat dissipation assembly 4 includes an auxiliary heat dissipation box 41, and a plurality of auxiliary heat dissipation channels 43 passing through the auxiliary heat dissipation box 41. The extension direction of the auxiliary heat dissipation box 41 is the third direction, and the extension direction of each auxiliary heat dissipation channel 43 is the first direction. A first transfer tube 44 and a second transfer tube 45 are provided at the top of the auxiliary heat dissipation box 41 near the end of the second mounting tube 38. The auxiliary heat dissipation box 41 is connected to the interior of the main heat dissipation box 31 through the second transfer tube 45, and the interior of the auxiliary heat dissipation box 41 is connected to the second mounting tube 38 through the first transfer tube 44.

[0070] like Figure 4 and Figure 5 As shown, first Figure 5 After the middle connecting pipe 312 is removed, refer to Figure 4 The first transfer pipe 44 is flange-connected to the first pipe 310, and the second transfer pipe 45 is flange-connected to the second pipe 311 to achieve the purpose of communication; further, a second baffle plate 42 extending in the third direction is provided in the auxiliary heat dissipation box 41, and the refrigerant entering the auxiliary heat dissipation box 41 will first flow along the second baffle plate 42 and the top wall inside the auxiliary heat dissipation box 41, and then flow along the second baffle plate 42 and the bottom wall inside the auxiliary heat dissipation box 41, and finally be discharged from the first transfer pipe 44, thereby improving the flow path of the refrigerant; further optionally, as Figure 6 As shown, the first transfer tube 44 can be eliminated, and a third transfer tube 46 is set at the bottom of the auxiliary heat sink 41. The third transfer tube 46 is flange-connected to the first tube 310 in the main heat sink assembly 3 below, and an avoidance through hole 48 for the third transfer tube 46 to pass through is provided in the middle of the second reinforcing rod 39. The unused first tube 310 is flange-connected to the second blocking member 47 to prevent the refrigerant from leaking. This design allows the refrigerant in liquid form after cooling to flow more smoothly into the return liquid channel 23. If the first transfer tube 44 is used, some liquid will accumulate at the end of the auxiliary heat sink 41, and the lower edge can rise to the first transfer tube 44 only under pressure-driven conditions. However, if the third transfer tube 46 is used, no liquid will accumulate, and the refrigerant will flow more smoothly.

[0071] In some embodiments, a support assembly 5 is provided between the middle rack 12 and the top rack 13 , and the support assembly 5 is used to install and fix the heat dissipation mechanism 2 to ensure that the heat dissipation mechanism 2 can be disassembled and reassembled, so that the user can add or reduce the auxiliary heat dissipation assembly 4 .

[0072] In some embodiments, the support assembly 5 includes two fixed oblique rods 51 arranged between the middle frame 12 and the top frame 13. The two fixed oblique rods 51 are arranged on both sides of the heat dissipation mechanism 2 along the third direction. The extension direction of the fixed oblique rods 51 is the second direction. Each first mounting tube 34 is detachably connected to a fixed oblique rod 51 through a clamping connector 52, and each second mounting tube 38 is connected to another fixed oblique rod 51 through a clamping connector 52.

[0073] like Figure 1 and Figure 7 As shown, all first mounting tubes 34 are fixed on a fixed inclined rod 51, and all second mounting tubes 38 are fixed on another fixed inclined rod 51, so that all main heat dissipation components 3 are fixed, thereby achieving the purpose of fixing the heat dissipation mechanism 2 and ensuring the stability of the heat dissipation mechanism 2 during use.

[0074] In some embodiments, the clamping connector 52 includes two clamping blocks 521 distributed on both sides of the fixed diagonal rod 51 along the first direction, and the two clamping blocks 521 are provided with a first semicircular groove 522 that fits with the outer wall of the fixed diagonal rod 51 at the ends close to each other, and a second semicircular groove 523 that fits with the outer wall of the first mounting tube 34 or the second mounting tube 38. The two clamping blocks 521 are provided with side plates 524 at both ends along the third direction, and the two side plates 524 located at the same end are connected by bolts and nuts.

[0075] like Figure 7 and Figure 8 As shown, by separating the bolts and nuts between the two side plates 524, the two clamping blocks 521 can be separated, thereby achieving the purpose of disassembly. The heat dissipation mechanism 2 can add an auxiliary heat dissipation component 4 as appropriate according to the usage. Therefore, when adding or deleting the auxiliary heat dissipation component 4, the position of the first mounting tube 34 and the second mounting tube 38 changes. It is only necessary to separate the bolts and nuts between the two side plates 524 first, and then adjust the position of the two clamping blocks 521 along the fixed diagonal rod 51 after the separation is completed, and then use the bolts and nuts to lock the two clamping blocks 521 again to complete the fixation of the first mounting tube 34 and the second mounting tube 38, thereby ensuring the normal use of the main heat dissipation box 31 and the auxiliary heat dissipation component 4.

[0076] In some embodiments, the main heat dissipation component 3 has a plurality of first channel groups evenly arranged along the second direction, and each first channel group includes a plurality of main heat dissipation channels 33 evenly distributed along the third direction and arranged in an odd-numbered manner and in an even-numbered manner;

[0077] The auxiliary heat dissipation component 4 has a plurality of second channel groups evenly arranged along the second direction, and each second channel group includes a plurality of auxiliary heat dissipation channels 43 arranged in the same manner as the main heat dissipation channels 33 .

[0078] like Figure 4 and Figure 5As shown, the starting position of the main heat dissipation channel 33 and the starting position of the auxiliary heat dissipation channel 43 are the same, and are arranged along the air intake channel 22 toward the liquid return channel 23 side; in addition, the first channel group is set according to the number of the first baffles 32. When the number of the first baffles 32 is two, the number of the first channel groups is three, which are respectively arranged between one of the first baffles 32 and the top wall of the main heat dissipation box 31, between two first baffles 32, and between the other first baffle 32 and the bottom wall of the main heat dissipation box 31; and the second channel group is set according to the number of the second baffles 42, and is arranged between the second baffle 42 and the inner top wall of the auxiliary heat dissipation box 41, and the second baffle 42 Between the auxiliary heat dissipation box 41 and the inner bottom wall, it can fully contact with the flowing refrigerant to achieve efficient heat dissipation function. In addition, because the odd-numbered items and the even-numbered items are staggered, the flow direction of the refrigerant airflow is more diverse, avoiding the refrigerant airflow flowing in only one direction, resulting in the problem of being unable to contact part of the main heat dissipation channel 33 or part of the auxiliary heat dissipation channel 43. In addition, although the arrangement is the same, the first transfer tube 44 and the second transfer tube 45 need to be laid out, so the length of the auxiliary heat dissipation box 41 will be slightly longer than the main heat dissipation box 31. Therefore, the number of auxiliary heat dissipation channels 43 in a second channel group will be slightly more than the main heat dissipation channels 33 in a first channel group.

[0079] In some embodiments, the chiller further includes two cooling mechanisms 6 disposed on the rack 1 and corresponding to the two heat dissipation mechanisms 2 respectively, and each cooling mechanism 6 includes:

[0080] The first wiping block 69 is arranged on the wind receiving plane side of the heat dissipation mechanism 2, and its extension direction is the third direction, and it can move along the second direction to wipe the wind receiving plane;

[0081] The first driving assembly is used to drive the first wiping block 69 to move along the second direction.

[0082] like Figure 3 and Figure 8 As shown, after adding the auxiliary heat dissipation component 4, the auxiliary heat dissipation box 41 has a secondary wind receiving surface flush with the wind receiving surface, and each secondary wind receiving surface is also within the wind receiving plane. The main heat dissipation box 31 will exchange heat with the airflow through the wind receiving surface, and the auxiliary heat dissipation box 41 will exchange heat with the airflow through the secondary wind receiving surface, and the temperature will be further reduced on the basis of the main heat dissipation channel 33 and the auxiliary heat dissipation channel 43. Fig. 9 The wind receiving surface is wiped by the first wiping block 69 to remove dust adhering to the wind receiving surface and the secondary wind receiving surface, thereby preventing the dust from reducing the heat dissipation effect.

[0083] In some embodiments, the cooling mechanism 6 further includes a main rod 66 disposed on the side of the first wiping block 69 away from the wind receiving plane, and connecting rods 65 are provided at both ends of the main rod 66 along the third direction, and a water storage channel 67 is provided inside the main rod 66 and the connecting rod 65, and a plurality of drainage holes 68 are evenly arranged along the third direction at the end of the main rod 66 close to the first wiping block 69, and one end of the drainage hole 68 is opened to communicate with the water storage channel 67, and the other end is opened to fit the first wiping block 69;

[0084] A wetting component 8 is provided on the frame 1 , and the wetting component 8 is used to transport water into the water storage channel 67 .

[0085] like Fig. 9 and Fig.11 As shown, the wetting component 8 delivers water into the water storage channel 67. As the amount of water in the water storage channel 67 increases, part of the water flows along the drainage pores 68 to the first wiping block 69. The first wiping block 69 can be made of sponge or cotton, etc., which can store part of the water and leave part of the water on the wind-receiving surface and the secondary wind-receiving surface during the wiping process. Through the evaporation of the water, the heat dissipation effect of the main heat sink 31 and the secondary heat sink 41 is further improved. Further, as shown in FIG. Figure 8 As shown, the wind receiving surface of the main heat sink 31 is provided with a first raised strip 611 extending along the third direction, and the secondary wind receiving surface of the secondary heat sink 41 is provided with a second raised strip 612 extending along the third direction. When the first wiping block 69 passes through the first raised strip 611 or the second raised strip 612, it will be squeezed by the two, which can squeeze out the water in the first wiping block 69, and more water further improves the heat dissipation effect.

[0086] In some embodiments, the wetting component 8 includes: an auxiliary water tank 81 arranged on the bottom frame 11, a water pump 83 arranged on the auxiliary water tank 81, and a water inlet tee 85 arranged on the middle frame 12, the water inlet of the water pump 83 is connected to the auxiliary water tank 81, the water outlet of the water pump 83 is connected to one opening of the water inlet tee 85, and the other two openings of the water inlet tee 85 are respectively connected to the water storage channel 67.

[0087] like Figure 1 and Figure 7 As shown, the auxiliary water tank 81 is connected to the water inlet of the water pump 83 through the water inlet pipe 82, and the water outlet of the water pump 83 is connected to an opening of the water inlet tee 85 through the water delivery pipe 84, so as to achieve the main purpose of pumping water and delivering water. In addition, the other two openings of the water inlet tee 85 are provided with water inlet hoses 610, and the other ends of the two water inlet hoses 610 are respectively connected to the connecting rods 65 of the corresponding cooling mechanism 6, connecting the water storage channel 67 and the water inlet tee 85, so as to achieve the purpose of conveying water into the water storage channel 67. Optionally, the water pump 83 uses a smaller power model to avoid the situation where the power is too high and the water is conveyed too much.

[0088] In some embodiments, the first driving assembly includes two mounting frames 61 which are arranged at the top of the top frame 13 and correspond to the position of the connecting rod 65. Each mounting frame 61 is provided with a rotatable first screw 63. Each first screw 63 passes through the top frame 13 and is rotatably connected to the top of the middle frame 12. A first internally threaded tube 64 is threadedly connected to the middle part of each first screw 63. The two first internally threaded tubes 64 are respectively connected to the two connecting rods 65. A first linkage belt 613 is sleeved between the bottoms of the two first screws 63. A first motor 62 is provided on a mounting frame 61. The output shaft of the first motor 62 is connected to the corresponding first screw 63 on the mounting frame 61. The first motor 62 drives the corresponding first screw 63 to rotate, thereby driving the main rod 66, the connecting rod 65 and the first wiping block 69 to move along the second direction.

[0089] like Figure 7 , Fig. 9 , Fig.10 and Fig.11 As shown, a first screw 63 is driven to rotate by the first motor 62, and then another first screw 63 is driven to rotate by the first linkage belt 613. The two first internally threaded tubes 64 are restricted by the connecting rod 65 and the main rod 66 and cannot rotate together. Therefore, they move along the first screw 63 under the action of the thread, and the two first internally threaded tubes 64 are respectively connected to the two connecting rods 65, thereby driving the main rod 66, the connecting rod 65 and the first wiping block 69 to move in the second direction, thereby achieving the purpose of wiping the wind-receiving surface.

[0090] In some embodiments, the chiller further includes a cleaning mechanism 7 disposed on the frame 1 and corresponding to the two heat dissipation mechanisms 2 respectively, and the cleaning mechanism 7 is used to clean the inner wall of the main heat dissipation channel 33 and the inner wall of the auxiliary heat dissipation channel 43, such as Fig.12 , Fig.13 and Fig.14 As shown, dust is prevented from adhering to the inner wall of the main heat dissipation channel 33 or the inner wall of the auxiliary heat dissipation channel 43, thereby avoiding the situation where the heat dissipation effect is reduced.

[0091] In some embodiments, the cleaning mechanism 7 comprises:

[0092] A plurality of second wiping blocks 710 are arranged on the side of the heat dissipation mechanism 2 away from the wind receiving plane, and are arranged in the same manner as the arrangement of the main heat dissipation channels 33 in the first channel group, and can be moved along the first direction to wipe the inner wall of the main heat dissipation channel 33 or the inner wall of the auxiliary heat dissipation channel 43;

[0093] A second driving assembly, used for driving each second wiping block 710 to move along a first direction;

[0094] The third driving assembly is used to drive each second wiping block 710 to move along the second direction, corresponding to the first channel group or the second channel group.

[0095] like Fig.12 , Fig.13 and Fig.14 As shown, each second wiping block 710 is first moved to a position corresponding to a first channel group or a second channel group by the third driving component, and then each second wiping block 710 is driven by the second driving component to move and wipe the inner wall of the main heat dissipation channel 33 or the inner wall of the auxiliary heat dissipation channel 43. Because the number of auxiliary heat dissipation channels 43 in a second channel group is slightly more than the main heat dissipation channels 33 in a first channel group, in order to avoid excessive second wiping blocks 710 interfering with other components, the number of second wiping blocks 710 is set to be the same as the number of main heat dissipation channels 33 in a first channel group. Although some auxiliary heat dissipation channels 43 are still not cleaned, these auxiliary heat dissipation channels 43 are at the tail end of the heat dissipation, where the heat is basically dissipated and converted into liquid refrigerant, which will not affect the overall heat dissipation effect.

[0096] In some embodiments, the second drive assembly includes a mounting plate 75 disposed on the side of the heat dissipation mechanism 2 away from the wind receiving plane, the extension direction of the mounting plate 75 is the third direction, a micro motor 76 is embedded and installed at one end of the mounting plate 75, the output shaft of the micro motor 76 is connected to a worm 77, the extension direction of the worm 77 is the third direction, and the mounting plate 75 is provided with a limiting through hole 78 arranged in the same manner as the main heat dissipation channels 33 in the first channel group, each limiting through hole 78 is provided with a third screw 79, each third screw 79 extends in the first direction, and is provided with a limiting groove 714 penetrating along the third direction, the limiting groove 7 The extension direction of 14 is the same as the extension direction of the third screw 79. A central limiting rod 713 is provided inside the limiting through hole 78 and passes through the limiting groove 714. Each third screw 79 is connected to a worm gear 711 by a thread. Each worm gear 711 is meshingly connected to the worm 77. An L-shaped limiting rod 712 is provided on the mounting plate 75 away from the wind-receiving plane side and corresponding to the outer edge of each worm gear 711. Each worm gear 711 is located between the corresponding L-shaped limiting rod 712 and the mounting plate 75. Each L-shaped limiting rod 712 and the mounting plate 75 limit the corresponding worm gear 711 from moving along the first direction to ensure the stable rotation of the worm gear 711.

[0097] like Fig.13 , Fig.14 and Fig.15 As shown, the micro motor 76 drives the worm 77, and through the meshing transmission, the worm 77 drives each worm wheel 711 to rotate, and the center limit rod 713 passes through the limit groove 714, so that the third screw 79 cannot rotate synchronously with the worm wheel 711, and then through the action of the thread, the third screw 79 moves along the first direction. During the movement, the center limit rod 713 is always located inside the limit groove 714 to ensure the stability of the movement, and finally the third screw 79 drives the second wiping block 710 to move along the first direction to clean the inner wall of the main heat dissipation channel 33 or the inner wall of the auxiliary heat dissipation channel 43.

[0098] In some embodiments, the third driving assembly includes two second screws 72 arranged on two mounting frames 61 of the same cooling mechanism 6, the axis extension direction of each second screw 72 is the second direction, each second screw 72 passes through the top frame 13 and is rotatably connected to the top of the middle frame 12, and the middle part of each second screw 72 is connected with a second internal threaded tube 73 through a thread, and the two second internal threaded tubes 73 are respectively connected to the two ends of the mounting plate 75, and a second linkage belt 74 is sleeved between the bottoms of the two second screws 72. A second motor 71 is provided on a mounting frame 61, and the output shaft of the second motor 71 is connected to the corresponding second screw 72 on the mounting frame 61. The second motor 71 drives the corresponding second screw 72 to rotate, thereby driving the mounting plate 75 and each second wiping block 710 to move along the second direction.

[0099] like Figure 7 , Fig.12 and Fig.13 As shown, a second screw rod 72 is driven to rotate by a second motor 71, and another second screw rod 72 is driven by a second linkage belt 74, while the two second internal threaded tubes 73 are restricted by the mounting plate 75 and cannot rotate together. Therefore, under the action of the thread, the second screw rod 72 drives the mounting plate 75 to move, so that each second wiping block 710 installed on the mounting plate 75 corresponds to a first channel group or a second channel group.

[0100] The chiller usage process in this embodiment:

[0101] During conventional heat dissipation, the compressor 14 drives the refrigerant to enter the air intake channel 22 along the air intake main pipe 25, and then enter each main heat dissipation box 31 through each air intake branch pipe 35, and then return to the liquid return channel 23 through the connecting pipe 312, and finally flow into the evaporator 15 through the liquid return main pipe 26, completing the main heat dissipation function;

[0102] If it is necessary to improve the heat dissipation efficiency, first separate the two clamping blocks 521 of each clamping connector 52, then separate the adjacent first mounting tubes 34 and the adjacent second mounting tubes 38; install the telescopic tube 36 between the adjacent first mounting tubes 34 and the adjacent second mounting tubes 38; then fix the corresponding two clamping blocks 521 to complete the fixation of the first mounting tube 34 and the second mounting tube 38. At this time, there is a gap between the adjacent main heat dissipation boxes 31 along the second direction, and the auxiliary heat dissipation box 41 is placed in the gap. The connecting pipe 312 is removed, and the first transfer tube 44 is flange-connected to the first pipe 310, and the second transfer tube 45 is flange-connected to the second pipe 311. When heat dissipation is performed later, the refrigerant flowing out of the main heat dissipation box 31 will flow into the auxiliary heat dissipation box 41 through the second transfer tube 45, and then flow into the second mounting tube 38 through the first transfer tube 44, that is, flow back into the return liquid channel 23.

[0103] When it is necessary to clean the wind-receiving surface, the first motor 62 is started to drive the first wiping block 69 to move along the second direction and wipe the wind-receiving surface, and the first motor 62 can be reversed to drive the first wiping block 69 to move back and forth to wipe the wind-receiving surface; when it is necessary to improve the heat dissipation efficiency, the water pump 83 is started, and the water will enter the water storage channel 67 along the water supply main pipe 84, the water inlet tee 85 and the water inlet hose 610, and flow to the first wiping block 69 along the drainage pores 68. During the wiping process, the water remains on the wind-receiving surface of the main heat dissipation box 31 and the secondary wind-receiving surface of the secondary heat dissipation box 41;

[0104] When it is necessary to clean the inner wall of the main heat dissipation channel 33 and the inner wall of the auxiliary heat dissipation channel 43, first start the second motor 71 to drive the mounting plate 75 and each second wiping block 710 to move along the second direction, and adjust each second wiping block 710 on the mounting plate 75 to correspond to a first channel group or a second channel group; then turn off the second motor 71, start the micro motor 76, drive the second wiping block 710 to move along the first direction to clean the inner wall of the main heat dissipation channel 33 or the inner wall of the auxiliary heat dissipation channel 43, then reverse the micro motor 76, drive the second wiping block 710 to retract along the first direction, turn off the micro motor 76 and start the second motor 71 again, adjust the second wiping block 710 to the position of other first channel groups or second channel groups, and clean again.
