Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a liquid cooling unit. Background Technology

[0002] With the development of the energy storage industry, the energy storage temperature control industry has also developed rapidly. Catalyzed by industry growth, the widening peak-valley electricity price gap has improved the economics of energy storage; under two-part tariffs, configuring energy storage power stations can reduce capacity costs; and in the event of power curtailment, energy storage becomes a backup power source. The rapid development of the energy storage industry involves the increasing temperature of batteries during charging and discharging. To ensure their stability and safety, measures need to be taken to accelerate heat dissipation. Currently, energy storage air conditioners are commonly used for heat dissipation. There are two types of energy storage air conditioners on the market: air-cooled and liquid-cooled. Currently, liquid-cooled units are gradually becoming the main means of energy storage temperature control. With the development of energy storage battery technology, high-capacity cells are increasingly being used, and the installed density of energy storage systems is gradually increasing, placing higher demands on the cooling system's capacity. There is an urgent need for air conditioning products with large airflow and high cooling capacity to adapt to the development of the energy storage industry. At the same time, different airflow cooling methods need to be designed specifically for different energy storage systems to meet the high-density and personalized heat dissipation needs of the energy storage industry.

[0003] The existing liquid chiller's exhaust structure causes hot air to overflow from the exhaust vent. The exhaust vent and return air vent are located close to each other, which can easily cause hot air to overflow and return to the liquid chiller through the return air vent, resulting in a short circuit between the exhaust and return air and affecting the heat dissipation of the liquid chiller. Utility Model Content

[0004] In response to the problems mentioned in the background technology, a liquid cooling unit is developed, which sets the exhaust port and return air port alternately to avoid short circuit between exhaust and return air and ensure the heat dissipation effect of the liquid cooling unit.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: This application provides a liquid-cooled unit, comprising: a housing that encloses a first cavity and a second cavity, the first cavity being located in the upper part of the housing and the second cavity being located in the lower part of the housing; the first cavity and the second cavity communicating, the second cavity communicating with the outside, and outdoor gas entering the housing through the second cavity; a condenser assembly housed in the first cavity; a compressor housed in the second cavity; a heat exchanger assembly housed in the second cavity; and a fan assembly disposed at the top of the first cavity, the fan being used to drive gas in the first cavity to be discharged outside the housing.

[0006] In some embodiments of this application, the housing includes four columns, a base, a top plate, and an auxiliary support. The upper and lower ends of the four columns are connected to the top plate and the base, respectively. The auxiliary support includes a vertical auxiliary support assembly and a horizontal auxiliary support assembly. The horizontal auxiliary support assembly is connected between adjacent columns, and the vertical auxiliary support assembly is supported between the horizontal auxiliary support assembly and the base. There are two condenser assemblies, with their upper ends spaced apart and their lower ends close together. The upper part of each condenser assembly is connected to the fan, and the auxiliary support supports the lower part of the condenser assembly. By providing the columns, base, and top plate, the overall housing is supported. By providing the auxiliary support, the condenser assemblies are supported. By arranging the two condenser assemblies in a V-shape, and placing a compressor below each condenser assembly, two refrigeration systems are formed, sharing the fan assembly and heat exchange system. This improves system redundancy and reliability, reduces the risk of single-point failure, and maximizes heat exchange efficiency.

[0007] In some embodiments of this application, the heat exchanger assembly includes a heat exchanger body, a heat exchanger fixing part, a heat exchanger mounting part, and a heat exchanger support part. The heat exchange gas mounting part is connected between the transverse auxiliary support assembly and the base. The heat exchanger mounting part is bent to form a receiving cavity. The heat exchange gas support part is installed in the receiving cavity and connected to the base. The heat exchanger body is installed on the heat exchanger support part within the receiving cavity. The heat exchanger fixing part fixes the heat exchanger body within the receiving cavity. The heat exchanger body is installed in the middle position within the housing via the heat exchanger fixing part and the heat exchanger mounting part to facilitate connection with the two refrigeration systems above.

[0008] In some embodiments of this application, an electrical control box is also included, which is connected between two adjacent columns; the transverse auxiliary support assembly includes multiple first support beams and condenser support beams; the multiple first support beams are respectively connected between two adjacent columns; the condenser support beams extend along the extension direction of the condenser assembly, one end of the condenser support beam is connected to the middle of the first support beam, and the other end of the condenser support beam extends towards the electrical control box; the connection point of two condenser assemblies is connected to the condenser support beam. By setting multiple first support beams to connect the condenser support beams to the housing, the condenser support beams are cantilevered to support the condenser assembly, realizing the installation of the condenser assembly within the housing. The multiple first support beams also divide the housing into upper and lower parts, providing support for sealing the upper part and providing air return to the lower part.

[0009] In some embodiments of this application, one end of the condenser support beam is mounted on the first support beam via the heat exchanger mounting portion. Both the condenser support beam and the heat exchanger assembly are connected to the first support beam via the heat exchanger mounting portion. The condenser support beam supports the condenser assembly, and the heat exchanger mounting portion is used to mount the heat exchanger. This arrangement allows for centralized placement of internal components within the casing, saving space.

[0010] In some embodiments of this application, the housing includes a fixed panel and an electrical control box door. The fixed panel and the electrical control box door are disposed on one side of the electrical control box to form a side wall of the housing. The fixed panel is fixedly disposed at the upper end between two adjacent columns of the electrical control box, and the upper end of the fixed panel is connected to the top plate. The electrical control box door is connected to the lower end between two adjacent columns of the electrical control box. An openable and closable electrical control box door is provided on the side wall of the housing near the electrical control box.

[0011] In some embodiments of this application, the upper end of the side wall of the housing without the electrical control box is provided with an upper sealing plate, which is connected between two adjacent columns; the lower end of the side wall of the housing without the electrical control box is provided with a lower sealing plate, which is connected between two adjacent columns, and the lower sealing plate has mesh openings; the upper sealing plate is connected to the lower sealing plate; adjacent upper sealing plates, the fixed panel, and the upper end of the electrical control box door are sequentially connected through the columns to form the first cavity; adjacent lower sealing plates, the fixed panel, and the lower end of the electrical control box door are sequentially connected through the columns to form the second cavity. By providing a sealing plate at the upper end of the housing and providing ventilation mesh openings at the lower end of the housing, air conditioning return air is used, avoiding short circuits in the return air caused by opening the entire surface.

[0012] In some embodiments of this application, a first bottom side sealing plate is provided on the bottom end of the side wall near the electrical control box. The first bottom side sealing plate has mesh openings and is connected between the two columns near the electrical control box. The upper end of the first bottom side sealing plate is connected to the door of the electrical control box. The first bottom side sealing plate is provided on the side wall of the base. A second bottom side sealing plate is provided on the bottom end of the side wall of the housing opposite to the electrical control box. The second bottom side sealing plate has mesh openings and is connected between the lower side sealing plate and the base. The first bottom side sealing plate and the second bottom side sealing plate are arranged opposite to each other. By arranging the first bottom side sealing plate and the second bottom side sealing plate opposite to each other on the two side walls of the housing, and providing mesh openings on both the first bottom side sealing plate and the second bottom side sealing plate, and placing the first bottom side sealing plate on one side of the electrical control box, return air is achieved on one side of the electrical control box and the opposite side of the electrical control box. Furthermore, since both the first bottom side sealing plate and the second bottom side sealing plate are located on the bottom side of the housing, short circuit of the return air can be avoided.

[0013] In some embodiments of this application, the number of compressors is two. The two compressors are respectively positioned below the two condensers and on either side of the heat exchanger. The two compressors are connected to the two condensers via pipelines to form two refrigerant circulation systems. The heat exchanger is connected to a water pump via pipelines to form a coolant circulation system. The coolant circulation system is used for heat exchange with the heat source requiring heat exchange. The symmetrical arrangement of the two compressors and the symmetrical arrangement of the two independent refrigeration systems improve the reliability of system redundancy.

[0014] On the other hand, this application relates to a liquid-cooled unit, including a housing, a condenser assembly, a compressor, a heat exchanger assembly, and a fan. The housing has a through cavity formed therein; the condenser assembly is disposed in the upper part of the through cavity; the compressor is disposed in the lower part of the through cavity; the heat exchanger assembly is disposed in the lower part of the through cavity; and the fan is disposed in the top of the through cavity. An air inlet is formed on the housing at the bottom of the through cavity; wherein, a flow passage is formed from the air inlet, through the through cavity, to the fan, forming a flow path inside and outside the housing.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are: The system comprises a first cavity and a second cavity that are interconnected within the housing. The first cavity is located in the upper part of the housing, and the second cavity is located in the lower part of the housing. The first cavity and the second cavity are connected to form a through cavity. The chiller is located at the top of the first cavity for air outlet. Outdoor air can enter the housing through the second cavity, thus forming an air inlet and outlet passage for the housing. The air inlet is located at the bottom of the housing, and the air outlet is located at the top of the housing. The distance between the air inlet and the air outlet is relatively large, which can prevent the cold air discharged from the housing from directly returning to the housing through the air inlet, thus avoiding short-circuiting of exhaust and return air and affecting the heat dissipation of the liquid chiller unit.

[0019] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 11 As shown, a liquid-cooled unit is disclosed, comprising a housing 100, a condenser assembly 200, a compressor 300, a heat exchanger assembly, and a fan assembly 500. The housing 100 is used to house the condenser assembly 200, the compressor 300, the heat exchanger assembly, and the fan assembly 500.

[0020] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 As shown, there are two condenser assemblies 200. The two condenser assemblies 200 are arranged in a V-shape.

[0021] The fan assembly 500 is located on top of the housing 100, and the two condenser assemblies 200 are arranged in a V-shape below the fan assembly 500.

[0022] There are two compressors 300, each connected to one condenser assembly 200 via piping, forming two refrigerant circulation systems. Specifically, the two compressors 300 are positioned below the two condenser assemblies 200.

[0023] The heat exchanger assembly is located below the condenser assembly 200 and serves as an auxiliary support for the condenser assembly 200.

[0024] The heat exchanger assembly and the water pump are connected by pipelines to form a coolant circulation system.

[0025] Within the heat exchanger assembly, the refrigerant output from the condenser assembly 200 and the compressor 300 exchanges heat with the coolant output from the water pump, thereby enabling the coolant to obtain a lower temperature. The lower temperature of the coolant can cool down energy storage devices such as batteries.

[0026] like Figure 2 , Figure 3 As shown, the housing 100 encloses a first cavity 110 and a second cavity 120. The first cavity 110 communicates with the second cavity 120. The first cavity 110 is formed above the second cavity 120. The first cavity 110 is formed in the upper part of the housing 100. The second cavity 120 is formed in the lower part of the housing 100.

[0027] The condenser assembly 200 is housed within the first cavity 110.

[0028] The compressor 300 is housed within the second cavity 120.

[0029] The fan assembly 500 is located at the top of the first cavity 110.

[0030] The second cavity 120 is connected to the outdoors.

[0031] The fan assembly 500 drives the gas from the outside into the second chamber 120. The gas flows through the second chamber 120 and the first chamber 110, and is discharged to the outside from the fan assembly 500.

[0032] Because the air inlet is located at the bottom of the housing 100 and the air outlet is located at the top of the housing 100, the air outlet is far away from the air inlet, thus preventing the high-temperature gas discharged from the housing 100 from re-entering the housing 100.

[0033] Specifically, such as Figure 2 , Figure 3 As shown, the housing 100 includes four pillars 131. The four pillars 131 are rotatably positioned at the four vertices of a rectangle, forming a rectangular frame for the housing 100.

[0034] The housing 100 also includes a base 132, a top plate 133, and an auxiliary support. The upper and lower ends of the four columns 131 are connected to the top plate 133 and the base 132, respectively.

[0035] The condenser assembly 200 is disposed at the lower part of the top plate 133 of the housing 100 and connected to the fan assembly 500 mounted on the top plate 133.

[0036] The auxiliary support is used to support the lower part of the condenser assembly 200.

[0037] The auxiliary support includes a vertical auxiliary support component 134 and a horizontal auxiliary support component 135.

[0038] The horizontal auxiliary support component 135 is connected between adjacent columns 131, and the vertical auxiliary support component 134 is supported between the horizontal auxiliary support component 135 and the base 132.

[0039] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 11 As shown, the heat exchanger assembly includes a heat exchanger body 410, a heat exchanger fixing part 420, a heat exchanger mounting part 430, and a heat exchanger support part 440. The heat exchanger mounting part 430 is connected between the transverse auxiliary support assembly 135 and the base 132. The heat exchanger mounting part 430 is bent to form a receiving cavity 431. The heat exchanger support part 440 is mounted on the base 132 within the receiving cavity 431, and the heat exchanger body 410 is mounted on the heat exchanger support part 440 within the receiving cavity 431, and is received within the receiving cavity 431.

[0040] The heat exchanger fixing part 420 fixes the heat exchanger body 410 in the receiving cavity 431.

[0041] Specifically, the heat exchanger mounting section 430 includes two opposing side plates 432 formed by bending and a back plate 433 connected between the two side plates 432. The two opposing side plates 432 and the back plate 433 surround and form a receiving cavity 431.

[0042] The heat exchanger support 440 includes two vertical support plates 441 and a horizontal support plate 442. The two vertical support plates 441 are respectively connected to the lower ends of the horizontal support plate 442.

[0043] Two vertical support plates 441 are respectively disposed adjacent to the inner sidewalls of two oppositely arranged side plates 432. A horizontal support plate 442 is connected between the two vertical support plates 441.

[0044] The heat exchanger body 410 is mounted on the transverse support plate 442 and housed in the receiving cavity 431.

[0045] A flanged connecting portion 4321 is formed on the side of the side plate 432 that is not connected to the back plate 433. The heat exchanger fixing portion 420 includes a heat exchanger fixing plate 421 and two flanged fixing portions 422, which are respectively connected to both sides of the heat exchanger fixing plate 421. The flanged fixing portions 422 and the flanged connecting portion 4321 are connected by fasteners.

[0046] The liquid cooling unit also includes an electrical control box 600. The electrical control box 600 is located on one side wall within the housing 100. The electrical control box 600 is connected between two adjacent columns 131. The transverse auxiliary support assembly 135 includes multiple first support beams 1351 and condenser support beams 1352. The multiple first support beams 1351 are respectively connected between two adjacent columns 131.

[0047] The condenser support beam 1352 extends along the extension direction of the condenser assembly 200. Specifically, the condenser support beam 1352 extends along the extension direction of the connection between the two condenser assemblies 200.

[0048] The condenser support beam 1352 extends along the extension direction of the condenser assembly 200.

[0049] One end of the condenser support beam 1352 is connected to the middle of the first support beam 1351, and the other end of the condenser support beam 1352 extends toward the electrical control box 600. The condenser support beam 1352 is cantilevered.

[0050] The connection between the two condenser assemblies 200 is attached to the condenser support beam 1352.

[0051] The top of the heat exchanger mounting section 430 is connected to the first support beam 1351. One end of the condenser support beam 1352 is connected to the heat exchanger mounting section 430.

[0052] One end of the condenser support beam 1352 is mounted on the first support beam 1351 via the heat exchanger mounting part 430.

[0053] The heat exchanger mounting part 430 is connected between the first support beam 1351 and the base 132.

[0054] In some embodiments of this application, such as Figure 1 As shown, in order to enable the second cavity 120 to communicate with the outdoors, the first cavity 110 is not used for communication with the outdoors. The upper ends of the side walls of the housing 100 without the electrical control box 600 are each provided with an upper sealing plate 141. The upper sealing plate 141 connects between two adjacent columns 131. The upper sealing plate 141 connects between the upper parts of two adjacent columns 131. The adjacent upper sealing plates 141 enclose and form the first cavity 110.

[0055] The lower ends of the side walls of the housing 100 without the electrical control box 600 are each provided with a lower side sealing plate 142, which connects two adjacent uprights 131. The adjacent lower side sealing plates 142 enclose a second cavity 120. To allow the second cavity 120 to communicate with the outdoors, the lower side sealing plates 142 have mesh openings. Because of the mesh openings on the lower side sealing plates 142, the interior of the second cavity 120 can communicate with the outdoors through the mesh openings on the lower side sealing plates 142.

[0056] like Figure 1 As shown, the housing 100 includes a fixed panel 151 and an electrical control box door 152. The fixed panel 151 and the electrical control box door 152 are disposed on one side of the electrical control box 600 to form a side wall of the housing 100.

[0057] A fixed panel 151 is fixedly installed between two columns 131 adjacent to the electrical control box 600, and the upper end of the fixed panel 151 is connected to the top plate 133. The electrical control box door 152 is connected to the lower end between the two columns 131 adjacent to the electrical control box 600.

[0058] The upper ends of the adjacent upper sealing plate 141, fixed panel 151, and electrical control box door 152 are connected by columns 131 to form the first cavity 110. The lower end of the adjacent lower sealing plate 142, fixed panel 151, and electrical control box door 152 are connected by columns 131 to form a second cavity 120.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 10, Figure 11 As shown, a first bottom side sealing plate 161 is provided at the bottom end of the side wall near the electrical control box 600, and the first bottom side sealing plate 161 has mesh openings. The first bottom side sealing plate 161 is connected between two columns 131 located on both sides of the electrical control box 600.

[0060] The upper end of the first bottom side sealing plate 161 is connected to the electrical control box door 152. The first bottom side sealing plate 161 is set on the side wall of the base 132.

[0061] A second bottom side sealing plate 162 is provided at the bottom end of the side wall of the housing 100 opposite to the electrical control box 600. The upper end of the second bottom side sealing plate 162 is connected to the lower side sealing plate 142. The second bottom side sealing plate 162 is provided on the side wall of the base 132. The second bottom side sealing plate 162 has mesh openings.

[0062] The first bottom side sealing plate 161 and the second bottom side sealing plate 162 are arranged opposite to each other. Since both the first bottom side sealing plate 161 and the second bottom side sealing plate 162 have mesh openings, both the first bottom side sealing plate 161 and the second bottom side sealing plate 162 can be used for air intake.

[0063] In some embodiments of this application, there are two first bottom side sealing plates 161. The first bottom side sealing plates 161 are detachably connected to the side wall of the base 132. When the liquid cooling unit needs to be transported, the first bottom side sealing plates 161 can be removed from the side wall of the base 132 to form two first forklift holes. The forklift can insert the liquid cooling unit through the first forklift holes formed by removing the two first bottom side sealing plates 161.

[0064] Similarly, there are two second bottom side sealing plates 162. The second bottom side sealing plates 162 are detachably connected to the side wall of the base 132. When the liquid cooling unit needs to be transported, the second bottom side sealing plates 162 can be removed from the side wall of the base 132 to form two second forklift holes. The forklift can insert the liquid cooling unit through the second forklift holes formed by removing the two second bottom side sealing plates 162.

[0065] In other embodiments of this application, a liquid-cooled unit includes a through cavity 170 formed within a housing 100. A condenser assembly 200 is disposed in the upper part of the through cavity 170. A compressor 300 is disposed in the lower part of the through cavity 170. A heat exchanger assembly is disposed in the lower part of the through cavity 170. A fan assembly 500 is disposed in the top of the through cavity 170. An air inlet is formed on the housing 100 at the bottom of the through cavity 170.

[0066] The air flows from the air inlet, through the penetrating cavity 170 to the fan assembly 500, forming a flow path inside and outside the housing 100. The distance between the air inlet and the air outlet is relatively far.

[0067] In some embodiments of this application, a liquid cooling unit is involved, such as Figure 1 , Figure 10 As shown, it includes a housing 100, which includes a frame and an electrical control box door 152. The electrical control box door 152 is rotatably connected to the frame. The electrical control box door 152 is openable and closable on the frame.

[0068] The liquid-cooled unit also includes an electrical control box 600, which is installed inside the housing 100. During the overall installation of the liquid-cooled unit, if the electrical control box 600 is entirely located inside the housing 100, it presents significant inconvenience for operators when connecting pipes and wiring the entire unit. The electrical control box 600 can be rotatably connected to the frame. When it is necessary to operate on the pipes or other components behind the electrical control box 600, the electrical control box 600 can be rotated outside the housing 100.

[0069] To facilitate operation of the electrical control box 600 and to make it possible for the electrical control box 600 to rotate outside the housing 100, the electrical control box 600 is arranged adjacent to the electrical control box door 152. With the control box door 152 open, the control box 600 can be rotated outside the housing 100.

[0070] With the control box door 152 closed, the control box 600 is housed within the housing 100.

[0071] Specifically, the frame includes four columns. The four columns 131 are rotatably positioned at the four apex corners of the rectangle. This rectangular frame forms the housing 100.

[0072] The door 152 of the electrical control box is rotatably connected to the column 131.

[0073] The electrical control box 600 is rotatably connected to the column 131.

[0074] The electrical control box 600 is located inside the electrical control box door 152.

[0075] Specifically, the electrical control box door 152 and the electrical control box 600 are rotatably connected to the same column 131.

[0076] like Figure 1 , Figure 2 , Figure 10 , Figure 11 As shown, the housing 100 also includes a base 132. The lower ends of the four pillars 131 are connected to the base 132.

[0077] The base 132 is attached to the bottom of the frame.

[0078] Because the electrical control box 600 is quite heavy, and it is rotatably connected to the column 131, relying solely on this rotatable connection to support the weight of the electrical control box 600 poses a significant risk of it falling due to damage to the rotatable connection. Therefore, the liquid cooling unit also includes a bottom support 710 to support the electrical control box 600 from the bottom.

[0079] like Figure 14 , Figure 15 , Figure 16 As shown, the bottom support 710 includes a support component 711 and an anti-wear component 712. The support component 711 is connected to the base 132, and the anti-wear component 712 is connected to the bottom of the electrical control box 600. During the rotation of the electrical control box 600 relative to the frame, the anti-wear component 712 contacts the support component 711 to prevent the electrical control box 600 from directly rubbing against the bottom of the electrical control box 600 during its rotation relative to the housing 100, thus avoiding damage such as paint chipping.

[0080] Specifically, the support component 711 and the anti-wear component 712 can be made of stainless steel.

[0081] The wear-resistant component 712 includes an extension 7121 and a bent section 7122 that are connected to each other.

[0082] The extension section 7121 extends along the bottom of the electrical control box 600. The bending section 7122 bends from the extension section 7121 along the rear of the electrical control box 600.

[0083] Since the bending section 7122 bends to the rear of the electrical control box 600, during the process of the electrical control box 600 being turned into the housing 100, the bending section 7122 can prevent the electrical control box 600 from directly colliding with the housing 100 and causing damage to the electrical control box 600.

[0084] The extension section 7121 extends along the bottom of the electrical control box 600. During the rotation of the electrical control box 600, the extension section 7121 is used to contact the support component 711.

[0085] The support member 711 is bent to form a connecting part 7111 and an inlet support part 7112. The connecting part 7111 is used to connect the inlet support part 7112 to the base 132. The inlet support part 7112 is used to inlet and support the anti-wear member 712.

[0086] The guide support 7112 has a guide section 7113 and a support section 7114. The guide section 7113 is disposed away from the interior of the housing 100, and the support section 7114 is disposed close to the interior of the housing 100. The height of the guide section 7113 decreases from the distance ...

[0087] This allows the guide section 7113 to avoid the lower side of the control box door 152 during the process of the control box 600 being moved into the housing 100, thus preventing the control box door 152 from colliding with the base 132. Because the guide section 7113 is lower on the side closest to the outer side of the housing 100, the anti-wear component 712 connected to the lower part of the control box door 152 will not directly collide with the guide section 7113 during the closing process. However, due to the inclined arrangement of the guide section 7113, the gap between the anti-wear component 712 and the guide section 7113 gradually decreases until the anti-wear component 712 contacts the guide section 7113, or the anti-wear component 712 contacts the support section 7114. The support section 7114 supports the control box 600 by supporting the anti-wear component 712.

[0088] In some embodiments of this application, the bottom support 710 can support the electrical control box 600. The liquid cooling unit may also include a top fixing part, which includes a first top connecting part 721 and a second top connecting part 722. The first top connecting part 721 is connected to the frame, and the second top connecting part 722 is connected to the electrical control box 600. The first top connecting part 721 and the second top connecting part 722 are connected by fasteners. The second top connecting part 722 is connected to the top of the electrical control box 600, and the positions of the first top connecting part 721 and the second top connecting part 722 are correspondingly arranged. This achieves the fixation of the top of the electrical control box 600 to the frame.

[0089] In some embodiments of this application, such as Figure 1 As shown, the housing 100 also includes a side door 153, which is rotatably connected to the frame.

[0090] Specifically, the side door 153 is arranged adjacent to the electrical control box door 152, and the side door 153 and the electrical control box door 152 open and close relative to each other.

[0091] like Figure 2 , Figure 3 , Figure 10 , Figure 11 As shown, the liquid cooling unit also includes a replenishing water tank 520 and a charging valve. Both the replenishing water tank 520 and the charging valve are located inside the housing 100, near the side door 153. By opening the side door 153, the replenishing water tank 520 and the charging valve are exposed. Operators can observe the liquid level in the replenishing water tank 520 and replenish it through the open side door 153. The charging valve is used for maintenance of the refrigerant system.

[0092] like Figure 10 As shown, in order to lock the position between the electrical control box 600 and the electrical control box door 152, the liquid cooling unit also includes a first locking part 731 and a second locking part 732.

[0093] With the electrical control box 600 inserted into the housing 100 and the electrical control box door 152 closed, the first locking part 731 is used to lock the position of the electrical control box 600 and the electrical control box door 152.

[0094] The second locking part 732 is used for locking the position of the side door 153 and the electrical control box 600.

[0095] In some embodiments of this application, such as Figure 1 , Figure 10 As shown, a display screen door 154 is also provided on the electrical control box door 152, and the display screen door 154 is rotatably connected to the electrical control box door 152. A display screen 610 is provided on the electrical control box 600, and the display screen door 154 is positioned corresponding to the display screen 610. Opening the display screen door 154 exposes the display screen 610, which facilitates the operator's daily maintenance and operation of the unit, and reading the unit's operating information.

[0096] Since multiple electrical components are installed at the electrical control box 600, these components need to be waterproofed. When the electrical control box door 152 is closed relative to the housing 100, it must be able to prevent rainwater and other substances from entering the housing 100 through the gap between the electrical control box door 152 and the housing 100.

[0097] Specifically, the frame is a rectangular frame formed by four columns 131. The electrical control box door 152 and the side door 153 are located on the same side wall of the housing 100. The electrical control box door 152 and the side door 153 are set at the same height. Since the height of the electrical control box 600 and the replenishing water tank 520 is less than the overall height of the liquid cooling unit, a fixed panel 151 is provided above the electrical control box door 152 and the side door 153.

[0098] There is a gap between the fixed panel 151 and the upper edge of the electrical control box door 152 and side door 153 located below, and rainwater flows through the gap to the top of the electrical control box door 152 and side door 153.

[0099] The top of the electrical control box door 152 is bent to form the upper edge 1521 of the electrical control box door. The upper edge 1521 of the electrical control box door can initially block rainwater flowing into the gap between the fixed panel 151 and the electrical control box door 152.

[0100] Some rainwater can also enter the housing 100 through the gap between the end of the upper edge 1521 of the electrical control box door and the electrical control box. For example... Figure 11 , Figure 12As shown, to prevent the aforementioned possibility of water ingress, the liquid cooling unit also includes a second waterproof component. This second waterproof component includes a second sealing member 157 and a second bending member 158. The second bending member 158 is connected to the inside of the electrical control box door 152, and the second sealing member 157 is connected to the electrical control box 600. When the electrical control box door 152 is closed, the door abuts against the second sealing member 157.

[0101] The aforementioned second bending member 158 is connected below the upper edge 1521 of the electrical control box door. Specifically, the second bending member 158 extends horizontally and is located at the upper end of the inner side of the electrical control box door 152. A water-blocking edge 1581 and a sealing edge 1582 of the electrical control box door are formed on the second bending member 158. The water-blocking edge 1581 is located below the upper edge 1521 of the electrical control box door, and its height is higher than that of the electrical control box 600. Rainwater flows into the housing 100 from the end of the upper edge 1521 of the electrical control box door and flows onto the water-blocking edge 1581, along which the rainwater flows.

[0102] The second sealing component 157 extends horizontally and is disposed at the upper end of the electrical control box 600. The sealing edge 1582 of the electrical control box door abuts against the second sealing component 157, thereby preventing rainwater from flowing further downward through the second bending component 158 ​​into the electrical control box 600.

[0103] In some embodiments of this application, such as Figure 11 , Figure 12 As shown, to ensure the waterproof performance of the electrical control box 600, the liquid cooling unit also includes a first waterproof component, which includes a first sealing component 155 and a first bending component. The first bending component includes a horizontal extension section 1561 and a vertical extension section 1562. One end of the horizontal extension section 1561 is connected to the electrical control box 600, and the other end of the horizontal extension section 1561 is connected to the vertical extension section 1562. The first sealing component 155 is connected to the vertical extension section 1562.

[0104] When the electrical control box door 152 is closed, the electrical control box door 152 abuts against the first sealing component 155, thereby achieving a sealed connection between the electrical control box door 152 and the electrical control box 600.

[0105] The first bending component is arranged circumferentially on the outside of the electrical control box 600. Since the first sealing component 155 is installed on the vertical extension section 1562, and the first sealing component 155 is also arranged around the electrical control box 600, the electrical control box 600 is fully sealed and waterproof in all directions.

[0106] The first bending component 156 forms a drainage channel for the electrical control box by bending. Water that enters and accumulates in the drainage channel flows along the drainage channel to the bottom of the electrical control box 600, and then flows out of the drainage channel and out of the liquid cooling unit.

[0107] like Figure 10 , Figure 13 As shown, since the display screen door 154 can be opened relative to the electrical control box door 152, water may enter the housing 100 through the display screen door 154. Therefore, the liquid cooling unit also includes a third waterproof component, which includes a third sealing component 1591 and a third bending component 1592. The third bending component 1592 is arranged around the display screen, and the third sealing component 1591 is connected to the third bending component 1592. The third sealing component 1591 is arranged around the third bending component 1592. When the display screen door 154 is closed, the inner wall of the display screen door 154 abuts against the third sealing component 1591, thereby achieving a waterproof seal at the display screen.

[0108] In some embodiments of this application, a liquid cooling unit is involved, such as Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 11 As shown, it includes a condenser assembly 200, a fan assembly 500, a housing 100, an electrical control box 600, two compressors 300, and a heat exchanger assembly.

[0109] The electrical control box 600, the two compressors 300, and the heat exchanger assembly are all installed inside the housing 100.

[0110] The condenser assembly 200 includes two condenser bodies and a condenser mounting frame 220. The two condenser bodies are mounted on the condenser mounting frame 220. The lower ends of the two condenser bodies are arranged adjacent to each other and mounted on the lower end of the condenser mounting frame 220. The upper ends of the two condenser bodies are configured to be inclined in opposite directions and are respectively connected to both sides of the upper end of the condenser mounting frame 220.

[0111] The two condenser bodies are arranged symmetrically.

[0112] Specifically, such as Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 As shown, the two condenser bodies are arranged in a V-shape on the condenser mounting frame 220.

[0113] The fan assembly 500 is sealed to the top of the condenser mounting frame 220.

[0114] With the two condenser bodies installed on the condenser mounting frame 220, the fan assembly 500 is sealed to the condenser mounting frame 220 to achieve the installation of the fan assembly 500 and the condenser assembly 200.

[0115] The fan assembly 500 and the condenser assembly 200 are pre-assembled to form a heat dissipation module, which is a separate module with good sealing and easy assembly.

[0116] like Figure 5 , Figure 6 , Figure 7 , Figure 9 As shown, the condenser mounting frame 220 includes a first side 221, a second side 222, a first condenser sealing plate, a second condenser sealing plate, and a condenser support beam 225.

[0117] The two condenser bodies are defined as the first condenser body 211 and the second condenser body 212, respectively.

[0118] The first side portion 221 is connected between the end of the first condenser body 211 near the electrical control box 600 and the end of the second condenser body 212 near the electrical control box 600.

[0119] The second side portion 222 is connected between the end of the first condenser body 211 away from the electrical control box 600 and the end of the second condenser body 212 away from the electrical control box 600.

[0120] The first side portion 221 and the second side portion 222 are arranged in parallel.

[0121] The lower ends of the first side portion 221 and the second side portion 222 are both mounted on the condenser support beam 225.

[0122] The first condenser body 211 and the second condenser body 212 are mounted on the condenser support beam 225 via the first side 221 and the second side 222.

[0123] The first condenser sealing plate is connected between the first condenser body 211 and the fan assembly 500.

[0124] The second condenser sealing plate is connected between the second condenser body 212 and the fan assembly 500.

[0125] This enables the installation of the first condenser body 211, the second condenser body 212, the fan assembly 500, and the condenser mounting frame 220, thereby enabling the installation of the heat dissipation components.

[0126] In some embodiments of this application, such as Figure 7 , Figure 8 As shown, the first side portion 221 includes a side panel assembly and a clearance portion 2212.

[0127] The clearance portion 2212 is formed on the top of the side panel assembly and extends above the electrical control box 600 to avoid interference between the first side portion 221 and the electrical control box 600 located below.

[0128] Thus, the clearance portion 2212 extends into the top of the electrical control box 600, and the first side portion 221 is provided on one side of the electrical control box 600.

[0129] The second side portion 222 includes a side panel assembly.

[0130] Specifically, both the first side portion 221 and the second side portion 222 include side plate assemblies. Since the first side portion 221 is adjacent to the electrical control box 600, the side plate assembly of the first side portion 221 is connected to a clearance portion 2212, while the side plate assembly of the second side portion 222 does not need to be connected to a clearance portion 2212.

[0131] Thus, the two side plate assemblies are respectively connected to the two ends of the first condenser body 211 and the second condenser body 212.

[0132] like Figure 5 , Figure 6 , Figure 7 As shown, the side panel assembly includes a side panel body 22111, two first bent edges 22112, two second bent edges 22113, a third bent edge 22114, and a fourth bent edge 22115.

[0133] The first bent edge 22112 of the first side portion 221 and the first bent edge 22112 of the second side portion 222 are respectively bent along the two sides of the side plate body 22111.

[0134] Both the first bent edge 22112 of the first side portion 221 and the first bent edge 22112 of the second side portion 222 are bent outwards.

[0135] The first bent edge 22112 formed at the first side 221 and the first bent edge 22112 formed at the second side 222 are used to install the first condenser body 211 and the second condenser body 212.

[0136] A second bend 22113 is formed by bending the first bend 22112. The first bend 22112 and the second bend 22113 enclose a first receiving area, which is used to receive the liquid collecting pipe of the first condenser body 211 and the liquid collecting pipe of the second condenser body 212. This protects the liquid collecting pipe from damage during installation.

[0137] Meanwhile, the bending of the side plate body 22111 forms the first bent edge 22112 and the second bent edge 22113, thereby enhancing the structural strength of the first side 221 and the second side 222.

[0138] The third bend 22114 is connected between the two first bends 22112, and the third bend 22114 is connected to the condenser support beam 225.

[0139] The third bend edge 22114 of the first side portion 221 and the third bend edge 22114 of the second side portion 222 are respectively connected to both ends of the condenser support beam 225. This connects the first side portion 221 and the second side portion 222 to both ends of the condenser support beam 225, thereby connecting the first condenser body 211 and the second condenser body 212 to the condenser support beam 225.

[0140] The fourth bend edge 22115 of the first side portion 221 extends along the upper edge of the side plate body 22111 and the clearance portion 2212; the fourth bend edge 22115 is used for a sealed connection with the fan assembly 500.

[0141] The fourth bend edge 22115 of the second side portion 222 extends along the upper edge of the side plate body 22111 and is used for sealing connection with the fan assembly 500.

[0142] To achieve a sealed connection between the first side 221, the second side 222 and the fan assembly 500.

[0143] like Figure 7 , Figure 9 As shown, the first condenser sealing plate is connected between the first condenser body 211 and the fan assembly 500 to seal the first condenser body 211 and the fan assembly 500.

[0144] The second condenser sealing plate is connected between the second condenser body 212 and the fan assembly 500 to seal the connection between the second condenser body 212 and the fan assembly 500.

[0145] The first condenser sealing plate includes a first condenser support beam bending edge 2231, two first side bending edges 2232 and a first top bending edge 2233. The first condenser support beam bending edge 2231 and the first top bending edge 2233 are connected. Both the first condenser support beam bending edge 2231 and the first top bending edge 2233 extend along the first condenser body 211. The two first side bending edges 2232 are respectively connected to the two ends of the first condenser support beam bending edge 2231 and the first top bending edge 2233. The bent edge 2231 of the first condenser support beam is abutted against the top of the first condenser body 211; The first side bend 2232 is connected to the top of the side plate body; The first top bend edge 2233 is connected to the fan assembly 500.

[0146] The second condenser sealing plate includes a second condenser support beam bending edge 2241, two second side bending edges 2242, and a second top bending edge 2243. The second condenser support beam bending edge 2241 and the second top bending edge 2243 are connected. Both the second condenser support beam bending edge 2241 and the second top bending edge 2243 extend along the second condenser body 212. The two second side bending edges 2242 are respectively connected to the two ends of the second condenser support beam bending edge 2241 and the second top bending edge 2243. The bent edge 2241 of the second condenser support beam is abutted against the top of the second condenser body 212; The second side bending edge 2242 is connected to the top of the side plate body respectively; The second top bend edge 2243 is connected to the fan assembly 500.

[0147] By setting the first condenser sealing plate and the second condenser sealing plate between the first condenser body 211, the second condenser body 212 and the top plate 133 respectively, air leakage between the top plate 133 and the first condenser body 211 and the second condenser body 212 is prevented.

[0148] like Figure 5 , Figure 6 , Figure 7 As shown, the condenser support beam 225 includes a connecting extension 2251 extending in the same direction, two fifth bends 2252, and two bends 2253. The two fifth bends 2252 are respectively connected to the outside of the connecting extension 2251, and the two bends 2253 are respectively connected to both sides of the two fifth bends 2252. The connecting extension 2251 extends between the lower end of the first condenser body 211 and the lower end of the second condenser body 212, and the third bent edge 22114 is connected to the connecting extension 2251. The lower ends of the first condenser body 211 and the second condenser body 212 respectively abut against two fifth bending edges 2252; the bending groove 2253 is connected to the housing 100. A drain hole is provided at the bottom of the bending groove 2253; a closed end 22532 is formed on the side of the bending groove 2253 near the electrical control box 600; an open end 22533 is formed on the side of the bending groove 2253 away from the electrical control box 600. The fan assembly 500 includes a fan body.

[0149] like Figure 1 , Figure 2As shown, the housing 100 includes a top plate 133 and a frame. The top plate 133 has mounting holes 1331. The fan body is mounted at the mounting holes 1331. The top plate 133 is mounted on the frame. The fourth bent edge 22115 is detachably connected to the top plate 133.

[0150] The circumferential edge of the top plate 133 is bent to form a second receiving area, and the first condenser sealing plate and the second condenser sealing plate are received in the second receiving area.

[0151] In other embodiments of this application, two condenser bodies are arranged in a V-shape on the condenser mounting frame 220 to form a condenser assembly. Then, a fan assembly is installed on the upper part of the condenser mounting frame 220 to form a heat dissipation module. Modularizing the heat dissipation module facilitates production and assembly. Furthermore, the overall assembly of the heat dissipation module provides good sealing, reduces air leakage, and improves the efficiency of the fan assembly 500. The overall structure of the heat dissipation module is robust, and the deformation is relatively small.
