Specific implementation

[0030] In order to make the utility model's purpose, technical scheme and advantage more clearly, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other implementation manners obtained by the ordinary skill in the art without making the creative labor belong to the range of the utility model.

[0031] See Figures 1-7The utility model provides a water -cooled cold water machine of built -in coil, including water -cooled cold water machine box body 1 and water delivery coil body 2, the axis of water delivery coil body 2 is vertical and is located inside water -cooled cold water machine box body 1, and the inner periphery of water delivery coil body 2 is coaxially provided with constraint support subassembly 7, to pass through constraint support subassembly 7 to carry out stable support of water delivery coil body 2, specifically, constraint support subassembly 7 includes constraint sleeve 702 and article flange 701, constraint sleeve 702 is located in the inner periphery lower part of water delivery coil body 2, and constraint sleeve 702 periphery and water delivery coil body 2 inner periphery vertical coaxial sliding fit, the periphery bottom of constraint sleeve 702 is fixed with the article flange 701 of flat placement and is supported by the top surface of article flange 701 of water delivery coil body 2 bottom, and the both sides position of constraint sleeve 702 inner periphery are all fixed with L type connecting frame 703, and the vertical portion top of L type connecting frame 703 is all higher than the top of water delivery coil body 2, and simultaneously the vertical portion top of L type connecting frame 703 is all through dismouting combination subassembly 6 with the inner top of water -cooled cold water machine box body 1 detachable combination, the effect that such setting is, through constraint sleeve 702 periphery and water delivery coil body 2 inner periphery vertical coaxial sliding fit of constraint support subassembly 7 and through the top surface support of article flange 701 of constraint sleeve 702 periphery of water delivery coil body 2 bottom, can realize the stable support of water delivery coil body 2.

[0032] Referring to Figures 1-6As shown, a disassembly assembly 6 is assembled on the inner top of the water-cooled chiller chassis 1. The disassembly assembly 6 is partially fixed to the top of the constraint support assembly 7. The water supply coil body 2 and the constraint support assembly 7 are detachably and fixedly assembled inside the water-cooled chiller chassis 1 via the disassembly assembly 6. Specifically, each disassembly assembly 6 includes a mating seat 605 and a fixing sleeve 601. The top of the vertical portion of the L-shaped connecting bracket 703 on both sides is vertically fixed with a mating seat 605. Limiting holes 608 are opened laterally on the outer end faces of the mating seats 605 on both sides, which are far apart from each other. Two fixing sleeves 601 are vertically fixed on the inner top surface of the chiller casing 1. Each fixing sleeve 601 has a vertically opening mating groove 604 on its bottom surface, and the mating groove 604 corresponds one-to-one with the mating seat 605 and slides vertically in contact with it. The outer end faces of the fixing sleeves 601 on both sides, which are far apart from each other, each have a horizontally opening mounting hole 606. Each mounting hole 606 is perpendicularly connected to its corresponding mating groove 604, and each mounting hole 606 is horizontally coaxially aligned with its corresponding limiting hole 608. Each mounting hole 606 slides horizontally coaxially with a limiting rod 607, and the inner ends of the limiting rods 607 on both sides, which are close to each other, are aligned with their corresponding limiting holes 608. The corresponding limiting hole 608 is coaxially slidingly engaged. The outer ends of the limiting rods 607 on both sides extend out of the outer end face of the corresponding fixing sleeve 601 and are coaxially fixed with handles 602. The portion of the limiting rod 607 located between the corresponding handle 602 and the outer end face of the fixing sleeve 601 is coaxially clearance-fitted with a spring 603, and the two ends of the spring 603 are respectively fixedly connected to the outer end face of the corresponding handle 602 and the fixing sleeve 601. The purpose of this arrangement is to enable vertical sliding engagement between the mating seat 605 and the mating groove 604 of the disassembly and assembly assembly 6 and lateral sliding engagement between the limiting rod 607 and the limiting hole 608. This method allows for the detachable assembly and disassembly of the water supply coil body 2 and the constraint support assembly 7 inside the water-cooled chiller housing 1. Furthermore, after separating the inlet pipe 202 and outlet pipe 201 of the water supply coil body 2 from their corresponding connecting hoses 5, simply pulling the limiting rod 607 out of the limiting hole 608 allows the mating seat 605 to vertically disengage from the mating groove 604, thus removing the water supply coil body 2 and the constraint support assembly 7 from the water-cooled chiller housing 1. The method of fixing, assembling, and disassembling the water supply coil body 2 and the constraint support assembly 7 inside the water-cooled chiller housing 1 is simple and easy to implement.

[0033] See Figures 1-6As shown, the following optimizations were made to the water-cooled chiller chassis body 1, the water supply coil body 2, the constraint support assembly 7, and the disassembly and assembly assembly 6. Specifically, for the water-cooled chiller chassis body 1 and the water supply coil body 2, an inlet pipe 8 and an outlet pipe 3 are horizontally inserted and fixed on both the upper and lower sides of one side of the water-cooled chiller chassis body 1. Both ends of the inlet pipe 8 and the outlet pipe 3 are coaxially provided with pipe joints 4, and the inner ends of the inlet pipe 8 and the outlet pipe 3 are coaxially connected to a connecting hose 5 through the pipe joints 4. The top and bottom of the water supply coil body 2 are respectively provided with an inlet pipe 202 and an outlet pipe 201 extending outward horizontally, and the inlet pipe 202 and the outlet pipe 201 are respectively connected to the adjacent connecting hose 5 through the pipe joints 4. This arrangement facilitates the connection of the inlet pipe 202 and the outlet pipe 201 to the inlet pipe 8 and the outlet pipe 3 through the connecting hose 5, respectively. Alternatively, all connecting hoses 5 are made of metal braided mesh, and all pipe fittings 4 are quick-connect fittings. This arrangement allows the connecting hoses 5 to have a certain degree of flexibility and deformation, making it easy for the pipe fittings 4 to be assembled and disassembled. It also allows the connecting hoses 5 to be quickly assembled and disassembled with the inlet pipe 202 and the outlet pipe 201, respectively, with the help of the pipe fittings 4.

[0034] See Figures 1-7 As shown, specifically regarding the constraint support component 7 and the disassembly and assembly component 6, the constraint sleeve 702 is an open cylinder, and the placement flange 701 is an annular flange with an outer diameter larger than the outer diameter of the water supply coil body 2. This design firstly ensures that the design of the constraint sleeve 702 meets the needs of supporting the inner circumference of the water supply coil body 2 from the inside, and secondly, it ensures that the top surface of the placement flange 701 can support the bottom of the water supply coil body 2. Optionally, both the mating seat 605 and the mating groove 604 have rectangular horizontal cross-sectional shapes to facilitate good positioning and guiding design when the mating seat 605 slides vertically along the mating groove 604. Additionally, the mating groove 604 can be a blind groove in the vertical direction, opening from bottom to top, and the top of the mating seat 605 can be in close contact with the inner top of the corresponding mating groove 604. With this arrangement, during the vertical sliding of the mating seat 605 along the mating groove 604, when the limiting hole 608 slides vertically with the mating seat 605 to align with the limiting rod 607 laterally, a clear indication can be provided by the contact between the top of the mating seat 605 and the inner top of the mating groove 604.

[0035] With the above structure, specifically inside the water-cooled chiller casing 1, a water supply coil body 2 and a constraint support assembly 7 are assembled inside the water-cooled chiller casing 1. The constraint sleeve 702 of the constraint support assembly 7 slides vertically coaxially with the inner circumference of the water supply coil body 2, and the bottom of the water supply coil body 2 is supported by the top surface of the placement flange 701 on the periphery of the constraint sleeve 702. This allows the water supply coil body 2 to be stably housed inside the water-cooled chiller casing 1 using the constraint support assembly 7. Specifically, when the water supply coil body 2 and the constraint support assembly 7 are assembled with the water-cooled chiller casing 1 using the disassembly and assembly assembly 6, the water supply coil body 2 and the constraint support assembly 7 are detachably and fixed to the water-cooled chiller casing 1 by the vertical sliding engagement of the mating seat 605 and the mating groove 604, and the horizontal sliding engagement of the limiting rod 607 and the limiting hole 608. Inside the chiller housing 1, the water supply coil body 2 and the constraint support assembly 7 are easily and simply fixed together, facilitating quick assembly of the water supply coil body 2 and the constraint support assembly 7 inside the chiller housing 1 for cooling water use. After separating the inlet pipe 202 and outlet pipe 201 of the water supply coil body 2 from their corresponding connecting hoses 5, it is only necessary to pull outwards by holding the handles 602 on both sides and using the springs... The stretching of 603 causes the limiting rods 607 to disengage from the limiting holes 608, allowing the mating seat 605 to vertically disengage from the mating groove 604, thus removing the water supply coil body 2 and the constraint support assembly 7 from the interior of the water-cooled chiller housing 1. The disassembly of the water supply coil body 2 and the constraint support assembly 7 inside the water-cooled chiller housing 1 is simple and easy to implement, which facilitates subsequent cleaning and maintenance after removing the water supply coil body 2 and the constraint support assembly 7 from the interior of the water-cooled chiller housing 1.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
