Description

Technical Field

[0001] This utility model relates to the field of chiller technology, and in particular to an insulation structure for air conditioning chillers. Background Technology

[0002] An air conditioning chiller is a highly efficient and energy-saving refrigeration equipment, consisting of four main components: a compressor, an evaporator, a condenser, and an expansion valve. This allows the unit to achieve both cooling and heating effects. In the evaporator, heat is absorbed from the object being cooled and vaporized into steam. The compressor continuously extracts the generated steam from the evaporator and compresses it. The high-temperature, high-pressure steam after compression is sent to the condenser, where it releases heat to the cooling medium (such as water or air) and condenses into a high-pressure liquid. After being depressurized by a throttling mechanism, the liquid enters the evaporator, vaporizes again, and absorbs heat from the object being cooled, thus creating a continuous cycle.

[0003] In existing technology, the evaporator of the air conditioning chiller unit is exposed. Because it is in a relatively low temperature state during operation, the cold energy is easily lost, which may form condensation on the outer wall and may affect the pipeline.

[0004] An existing patent (publication number: CN221944451U) discloses a thermal insulation structure for an air conditioning chiller unit. After the magnetic blocks of the first and second connecting plates come into contact with each other and are magnetically connected, the thermal insulation pad can be stably wrapped around the outer wall of the evaporator to keep the evaporator warm. The magnetic blocks of the first and second connecting plates can be easily pulled apart by the handle, and the thermal insulation pad can be opened at the same time. The installation and removal of the thermal insulation pad is relatively convenient. If the thermal insulation pad is accidentally damaged, the screw can be turned by turning the threaded rod to release the mating piece of the clamp, and the mating piece of the thermal insulation pad can be separated from the first and second connecting plates. The first and second connecting plates can be reused to install a brand new thermal insulation pad with the mating piece.

[0005] To address the aforementioned issues, while existing patents offer solutions that can insulate the evaporator by using components such as insulating pads, in actual use, the evaporator is only partially wrapped while other equipment remains open. This allows air circulation to affect the temperatures of each device, impacting the insulation effect. Summary of the Invention

[0006] The purpose of this utility model is to provide a heat preservation structure for air conditioning chiller units, which can separate the evaporator body from other chiller unit components to avoid mutual temperature influence, while also achieving a sealing effect to prevent temperature loss and thus providing a heat preservation effect. Furthermore, by attaching insulation cotton to the outer wall of the evaporator body, the heat preservation effect can be improved, and the structure can be easily disassembled and reassembled, avoiding the cumbersome manual disassembly and assembly process, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a heat preservation structure for an air conditioning chiller unit, comprising a heat preservation shell, an evaporator body embedded inside the heat preservation shell, a connecting pipe extending from inside the evaporator body, a condenser being inserted into one end of the connecting pipe extending out of the heat preservation shell, and a fixing block being fixedly installed on the upper part of the inside of the heat preservation shell, and a heat preservation mechanism being provided inside the fixing block.

A spring is fixedly installed at one end of the connecting rod inside the sleeve. A bonding plate is fixedly installed at the other end of the connecting rod that extends out of the sleeve. Insulation cotton is fixedly installed on one side of the outer wall of the bonding plate. A limit groove is formed at the bottom of the insulation shell corresponding to the position of the clamping plate.

[0009] Preferably, the clamping plate forms a sliding structure between the slider and the fixing block, and the slider is threadedly connected to the bidirectional threaded rod.

[0010] Preferably, the bonding plate has a semi-arc structure and is bonded to the insulation cotton.

[0011] Preferably, ventilation slots are provided at both ends of the insulation shell, and a sealing mechanism is provided inside the ventilation slots.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution:

[0029] Please see Figures 1 to 5 An insulation structure for an air conditioning chiller unit includes an insulation shell 1, an evaporator body 2 embedded inside the insulation shell 1, a connecting pipe 3 extending from the evaporator body 2, and a condenser 4 inserted into one end of the connecting pipe 3 extending out of the insulation shell 1. A fixing block 5 is fixedly installed on the upper part of the insulation shell 1, and an insulation mechanism 6 is provided inside the fixing block 5. The insulation mechanism 6 includes a motor 601, which is embedded in one side of the outer wall of the insulation shell 1. A bidirectional threaded rod 602 is fixedly installed at the power output end of the motor 601. A slider 603 is slidably connected to the outer wall of one end of the bidirectional threaded rod 602 that extends into the fixing block 5. A clamping plate 604 is fixedly installed at the bottom end of the slider 603 for clamping. A sleeve 605 is embedded in the outer wall of plate 604. A connecting rod 607 extends out of the inside of sleeve 605. A spring 606 is fixedly installed at one end of the connecting rod 607 inside sleeve 605. An adhesive plate 608 is fixedly installed at the other end of the connecting rod 607 extending out of sleeve 605. Insulation cotton 609 is fixedly installed on one side of the outer wall of adhesive plate 608. A limit groove 610 is formed at the bottom of the inner part of the insulation shell 1 corresponding to the position of clamping plate 604. Clamping plate 604 forms a sliding structure with fixing block 5 through slider 603. Slider 603 is threadedly connected to bidirectional threaded rod 602. The structure of adhesive plate 608 is a semi-arc structure. Adhesive plate 608 is bonded to insulation cotton 609.

[0030] By adopting the above technical solution, firstly, in the chiller unit, the evaporator body 2 is sealed by the insulation shell 1 to prevent heat loss and achieve a heat preservation effect. At the same time, it is separated from other equipment to avoid mutual temperature interference. Meanwhile, the connecting pipe 3 is used to connect with the condenser 4 and other equipment to maintain the operation of the chiller unit. The motor 601 drives the bidirectional threaded rod 602 to rotate, thereby allowing the two sliders 603 to slide along the fixed block 5, and driving the corresponding clamping plate 604 to slide stably along the limiting groove 610, moving towards the evaporator body 2. This allows the sleeve 605 to be pushed by the spring 606. The movable connecting rod 607 causes the bonding plate 608 to drive the insulation cotton 609 to adhere to the outer wall of the evaporator body 2, further improving the insulation effect, preventing heat loss, and avoiding the cumbersome manual disassembly and assembly, thus improving convenience. The outer wall of the insulation cotton 609 is made of aluminum foil, which can reflect heat and prevent heat loss, thus increasing the insulation effect. At the same time, the end of the connecting rod 607 that penetrates into the sleeve 605 is larger to prevent it from detaching from the sleeve 605. It is also elastically contracted by the spring 606 to prevent the rigid connection of the bonding plate 608 from damaging the outer wall of the evaporator body 2 when the chiller unit is subjected to vibration or external force.

[0031] Specifically, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, ventilation slots 7 are provided at both ends of the insulation shell 1. A sealing mechanism 8 is provided inside the ventilation slots 7. The sealing mechanism 8 includes a connecting rod 801, which is fixedly installed on the axial outer wall of the clamping plate 604. A sliding rod 802 is fixedly installed at the end of the connecting rod 801 away from the clamping plate 604. Sliding grooves 804 are provided at the upper and lower positions of the ventilation slots 7 corresponding to the sliding rod 802. A sealing cloth 803 is fixedly installed on one side of the sliding rod 802. The sealing mechanism 8 also includes a roller 805. The end of the sliding rod 802 that passes through the sliding groove 804 is rotatably connected to the roller 805. A support rod 806 extends out from the inside of the sealing cloth 803 and penetrates into the inside of the sealing cloth 803. The support rod 806 and the sliding groove 804 form a sliding structure.

[0032] By adopting the above technical solution, when the clamping plate 604 slides, the connecting rod 801 drives the sliding rod 802, which slides stably and smoothly along the slide groove 804 opened in the ventilation groove 7 via the roller 805. Under the sliding of the sliding rod 802, the sealing cloth 803 is driven to open and close the ventilation groove 7. When it is necessary to maintain the internal evaporator body 2 or other components, opening the ventilation groove 7 facilitates maintenance. Under normal circumstances, it is closed. The sealing cloth 803, made of PVC cloth or glass fiber cloth, has a certain degree of flexibility and can be folded with the movement of the sliding rod 802. It also has sealing and heat insulation properties, preventing heat loss and achieving a heat preservation effect when closed. The sealing cloth 803 is fixed and supported by the support rod 806, and slides along the slide groove 804 when the sealing cloth 803 is folded, which can prevent the sealing cloth 803 from twisting or deviating, which would cause gaps in the closed state and affect the heat preservation effect of the heat preservation shell 1.

[0033] Working Principle: First, the evaporator body 2 is installed through the insulation shell 1, achieving a sealing and insulation effect. The connecting pipe 3 extends out of the insulation shell 1 and connects to the condenser 4 and other equipment in the chiller unit, allowing the entire chiller unit to connect and operate normally. The motor 601 drives the bidirectional threaded rod 602 to rotate, causing the two sliders 603 to slide along the fixed block 5, and driving the corresponding clamping plate 604 to slide towards the evaporator body 2. The bottom end of the clamping plate 604 axially follows the limiting groove 610 to improve sliding stability. Under the fixation of the clamping plate 604, the spring 606 inside the sleeve 605 elastically pushes the connecting rod 607, allowing the bonding plate 608 to drive the insulation cotton 609 to adhere to and clamp the evaporator body 2, further improving the insulation effect and avoiding the troublesome manual installation. The spring 606 also prevents rigid connection. When subjected to external force, the bonding plate 608 may impact and damage the evaporator body 2. A sealing cloth 803 made of PVC cloth or fiberglass cloth is fixed between the sliding rod 802 and the ventilation groove 7. When maintenance or repair of the evaporator body 2 or the connecting pipe 3 is required, the slider 603 drives the clamping plate 604 through the cooperation of the motor 601 and the bidirectional threaded rod 602, thereby allowing the connecting rod 801 to drive the sliding rod 802. The sliding rod 802 slides stably and smoothly in the groove 804 via the roller 805, thereby allowing the sliding rod 802 to drive and press the sealing cloth 803. The reserved space facilitates maintenance and repair. The support rod 806 fixed inside the sealing cloth 803 also passes through the groove 804 to prevent the sealing cloth 803 from twisting, which would cause gaps when the insulation shell 1 is sealed.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
