TECHNICAL FIELD
[0001] The present application relates to the technical field of heat pump equipment, and in particular to a fixing structure and a heat pump. BACKGROUND
[0002] In the field of heat pump technology, the fixing structure of plate heat exchanger and liquid storage tank is crucial to the overall performance and stability of the system. Especially in refrigeration conditions, the surface temperature of the plate heat exchanger is lower than the ambient temperature, which easily leads to water vapor condensation and energy loss problems, so thermal insulation treatment becomes a key link. The current mainstream method is to attach thermal insulation cotton to the surface of the plate heat exchanger to reduce heat exchange, but this method faces some challenges in actual application. When the plate exchanger is tightly installed in the system by the fixing plate, the thermal insulation cotton is often squeezed, especially the sponge type thermal insulation material, the air gap inside it will be compressed. Although the sponge has a certain elastic recovery ability, but long-term pressure will cause it to gradually lose its original thickness and thermal insulation structure, and thus weaken the thermal insulation effect and increase energy loss, which not only affects the refrigeration efficiency of the system, but also may cause the formation of condensate drops or frost, threatening the stability and service life of the system. CONTENT OF THE UTILITY MODEL
[0003] The purpose of the embodiment of the present application is to provide a fixing structure and a heat pump. When the plate heat exchanger is wrapped with a thermal insulation piece and fixed with the first support, the designed protruding support piece ensures that the pressure borne by the thermal insulation piece is limited to a specific area in direct contact with the support piece. Compared with the traditional method of not adding support pieces, the overall squeezing area of the thermal insulation piece is significantly reduced, thereby protecting the integrity and structural stability of the thermal insulation piece.
[0004] To achieve the above purpose, the following technical solutions are adopted in the present application:
[0005] On the one hand, a fixing structure is provided, comprising: a plate heat exchanger, a liquid storage tank, a first support and a second support, the outer surface of the plate heat exchanger is wrapped with a thermal insulation piece, and is installed on the front face of the first support, the first support is provided with a support piece in contact with the thermal insulation piece, the second support is installed on the back face of the first support, and the liquid storage tank is hung on the second support.
[0006] Further, the support piece is provided with at least two, and the two support pieces are arranged at intervals on the front face of the first support.
[0007] Further, the second support comprises a connecting plate and a fixing plate, the connecting plate is installed on the back face of the first support, and the fixing plate is installed on the side of the connecting plate away from the first support.
[0008] Further, the back of the first support is provided with a plurality of sockets, and the connecting plate is provided with buckles corresponding to the plurality of sockets.
[0009] Further, the buckles are arranged in an array.
[0010] Further, the fixing plate is provided with a first stud, the liquid storage tank is provided with a first through hole corresponding to the first stud, and the first stud is locked with a first nut after penetrating through the first through hole.
[0011] Further, the upper part of the liquid storage tank is provided with a hanging buckle part, and the connecting plate is provided with a hanging buckle position corresponding to the hanging buckle part.
[0012] Further, the hanging buckle part is provided with a first fixing hole, and the fixing plate is provided with a second fixing hole corresponding to the first fixing hole.
[0013] Further, the plate heat exchanger is provided with a second stud, the first support is provided with a second through hole corresponding to the second stud, and the second stud is locked with a second nut after penetrating through the second through hole.

[0015] The beneficial effects of the present application are that the supports are protruded on the first support, and the supports and the thermal insulation member interact only in a specific and limited contact area. When the plate heat exchanger together with its thermal insulation layer is installed to the front surface of the first support, the supports are in contact with the thermal insulation member, thereby effectively dispersing and limiting the pressure borne by the thermal insulation member, avoiding the overall extrusion leading to the internal structure damage of the thermal insulation material.

The thermal insulation member can maintain its original thickness and thermal insulation structure for a long time, significantly improves the thermal insulation effect of the heat pump system, reduces energy loss, and effectively prevents the formation of condensate drops or frost, which is crucial for maintaining the refrigeration efficiency, stability and prolonging the service life of the system.

DETAILED DESCRIPTION
[0026] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the embodiments of the present application are described in further detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0027] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood in a broad sense, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0028] In the present application, unless specifically defined and limited otherwise, "on" or "under" of a first feature to a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "over" of a first feature to a second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. "Under", "below" and "underneath" of a first feature to a second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.
[0029] As shown in Figures 1-7 The present embodiment provides a fixing structure, comprising: a plate heat exchanger 1, a liquid storage tank 2, a first support 3 and a second support 4, the outer surface of the plate heat exchanger 1 is wrapped with a heat preservation member 5, and is installed on the front face of the first support 3, the first support 3 is provided with a support member 6 in contact with the heat preservation member 5, the second support 4 is installed on the back face of the first support 3, and the liquid storage tank 2 is hung on the second support 4.
[0030] Based on the above scheme, the fixing structure mainly comprises a plate heat exchanger 1, a liquid storage tank 2, a first support 3 and a second support 4. Among them, the outer surface of the plate heat exchanger 1 is carefully wrapped with a layer of heat preservation member 5, so as to effectively reduce heat exchange, especially prevent water vapor condensation and energy loss under refrigeration working condition. The key of this heat preservation measure is that the first support 3 is provided with specially designed support members 6, and these support members 6 are only in contact with the heat preservation member 5 in a specific area. When the plate heat exchanger 1 is installed on the front face of the first support 3, these support members 6 play a crucial role. They not only support the plate heat exchanger 1 and its heat preservation member 5, but more importantly, by limiting the contact area with the heat preservation member 5, the overall extrusion borne by the heat preservation member 5 is significantly reduced. Unlike the traditional method in which the heat preservation cotton is fully pressed, the support members 6 of the present design disperse the pressure, protect the integrity and structural stability of the heat preservation member 5, and prevent it from gradually losing the heat preservation effect due to long-term pressure.
[0031] In addition, the second support 4 is stably installed on the back face of the first support 3, and the liquid storage tank 2 is hung on the second support 4, so as to ensure that the key components of the whole heat pump system are stably and reasonably supported. This design not only improves the physical stability of the system, but also optimizes the heat preservation effect, reduces energy loss, and improves the refrigeration efficiency. More importantly, it effectively prevents the formation of condensate water drops or frost due to insufficient heat preservation, further guarantees the long-term stable operation of the system and prolongs the service life.
[0032] The support 6 is provided with at least two, and the two support 6 is arranged at the front of the first support 3. By arranging the support 6, the pressure borne by the heat preservation piece 5 can be more evenly distributed, which helps to prevent the heat preservation piece 5 from deforming or being damaged due to excessive local pressure, thereby further improving the stability and heat preservation effect of the heat preservation piece 5. Moreover, the support 6 arranged at intervals can be flexibly adjusted according to the size, shape and installation requirements of the plate heat exchanger 1 and the heat preservation piece 5, so that the fixing structure can be applied to different types of heat pump systems, improving its versatility and practicality.
[0033] It is worth mentioning that when the heat preservation piece 5 (such as sponge) on the plate heat exchanger 1 is subjected to long-term large-area extrusion, its elasticity and resilience will gradually lose due to compression fatigue. This compression deformation will cause the thickness of the heat preservation layer to decrease, thereby generating a thermal bridge effect. The thermal bridge effect is a phenomenon that heat is quickly transferred through the thinner area (i.e. thermal bridge) of the heat preservation layer, which will significantly increase heat loss and reduce the heat exchange efficiency of the entire system. To solve this problem, the fixing structure design proposed in this scheme shows significant advantages. By arranging the support 6 on the first support 3, the design effectively limits the pressure area of the heat preservation piece 5 (such as sponge), avoiding compression fatigue due to long-term large-area extrusion. The presence of the support 6 not only disperses the pressure, but also maintains the integrity and thickness of the heat preservation layer, thereby significantly reducing the occurrence of the thermal bridge effect.
[0034] In addition, this innovative design also prolongs the service life of the sponge heat preservation layer. As excessive compression deformation is avoided, the sponge can maintain its original elasticity and resilience, thereby maintaining excellent heat preservation effect for a long time. This not only reduces the long-term operation cost, but also reduces the frequency of replacing the heat preservation layer, bringing convenience to system maintenance.
[0035] More importantly, the fixing structure design ensures the thermal efficiency of the refrigeration system. By reducing heat loss and improving heat exchange efficiency, the system can operate more efficiently, thereby improving the overall energy efficiency ratio. This means that under the same refrigeration demand, the system can consume less energy and achieve higher energy utilization efficiency.
[0036] Further, the second support 4 includes a connecting plate 401 and a fixing plate 402, the connecting plate 401 is installed on the back of the first support 3, the fixing plate 402 is installed on the side of the connecting plate 401 away from the first support 3, the back of the first support 3 is provided with a plurality of sockets 302, and the connecting plate 401 is provided with buckles 4011 corresponding to the plurality of sockets 302. The connecting plate 401 is installed on the back of the first support 3, and the fixing plate 402 is installed on the side of the connecting plate 401 away from the first support 3, which allows the second support 4 and the first support 3 to form a stable connection structure. In order to further enhance the stability of the connection, the back of the first support 3 is provided with a plurality of sockets 302, and the connecting plate 401 is provided with buckles 4011 corresponding to the sockets 302. Through this precise buckling method, it can be ensured that the second support 4 and the first support 3 are tightly and reliably connected, avoiding performance degradation or safety hazards caused by looseness or misalignment.
[0037] Further, by setting the number of buckles 4011 to four and arranging them in an array on the connecting plate 401, this design not only ensures the precise docking of the buckles 4011 and the sockets 302 on the back of the first support 3, but also significantly improves the overall strength and stability of the structure by increasing the number of connection points. Since the shape and size of the buckles 4011 and the sockets 302 are precisely designed, they can easily achieve alignment. Once alignment is complete, the buckles 4011 and the sockets 302 can be firmly connected together through a welding process. This welding method not only ensures the strength of the connection, but also improves the overall rigidity of the structure, making the entire fixing structure more stable and reliable. The array distribution design of the buckles 4011 also brings convenience in the installation process. Since the number of buckles 4011 is moderate and evenly distributed, it can be ensured that quick and accurate positioning is achieved during installation. This not only improves installation efficiency, but also reduces the risk of performance degradation or safety hazards caused by improper installation.
[0038] More importantly, this design significantly reduces the risk of fatigue or fracture of the welding points by dispersing stress. In traditional welding structures, stress is often concentrated on the welding points, so these areas are more prone to damage. However, the present scheme evenly distributes stress to the entire connection area through the array distribution of the four buckles 4011 and sockets 302. This stress dispersion design not only improves the strength of the connection, but also prolongs the service life of the welding points, making the entire fixing structure more robust and durable.
[0039] In some embodiments, the fixed plate 402 is L-shaped as a whole, and by arranging a first stud 4021 on the fixed plate 402 and a first through hole 201 on the liquid storage tank 2 that matches the first stud 4021, the fixed plate 402 and the liquid storage tank 2 can be accurately aligned and fixedly connected.
[0040] Specifically, the first stud 4021 is firmly mounted on the fixed plate 402, and its position is accurately calculated and designed to ensure perfect alignment with the first through hole 201 on the liquid storage tank 2. Once aligned, the first stud 4021 can pass through the first through hole 201 and be locked together with the first nut. This connection not only provides strong connection strength, but also effectively resists various external forces and environmental influences, ensuring stable connection between the entire fixed structure and the liquid storage tank 2.
[0041] In addition, by using the stud and nut locking method, the relative position between the fixed plate 402 and the liquid storage tank 2 can be easily adjusted to adapt to different installation requirements and space limitations. This flexibility makes the fixed structure applicable to various types of heat pump systems, improving its versatility and practicality. Moreover, the locking structure between the stud and the nut can prevent loosening and falling off, thereby ensuring the stability and reliability of the entire fixed structure during long-term operation. At the same time, since the stud and the nut are standardized parts, they can be easily replaced and maintained, reducing the maintenance cost of the system.
[0042] At the same time, the upper part of the liquid storage tank 2 is provided with a hanging buckle part 202, and the connecting plate 401 is provided with a hanging buckle position 4012 that matches the hanging buckle part 202. The hanging buckle part 202 is a protruding part on the upper part of the liquid storage tank 2, and its shape and size are carefully designed to ensure matching with the hanging buckle position 4012 on the connecting plate 401. Once the hanging buckle part 202 is aligned with the hanging buckle position 4012, it can be fixed on the second bracket 4 by a simple hanging action. This connection method not only operates simply, but also can provide additional support to enhance the stability of the liquid storage tank 2. The matching between the hanging buckle part 202 and the hanging buckle position 4012 also has a certain self-adjusting ability. Since the hanging buckle part 202 usually has a certain elasticity or adjustability, it can adapt to the slight deviation or deformation between the liquid storage tank 2 and the second bracket 4 to a certain extent. This self-adjusting ability helps to maintain the stability and reliability of the entire structure and reduces the performance decline caused by improper installation or external forces.
[0043] Importantly, the connection between the hanging buckle part 202 and the hanging buckle position 4012 also has a certain safety redundancy. Even if other fixing methods (such as stud and nut locking) are loose or damaged, the hanging buckle part 202 can still provide a certain supporting force to prevent the liquid storage tank 2 from falling off or dumping. This safety redundancy design helps to improve the safety and reliability of the entire system.
[0044] It should be noted that the hanging buckle part 202 is provided with a first fixing hole 203, and the fixing plate 402 is provided with a second fixing hole 4022 corresponding to the first fixing hole 203. When the hanging buckle part 202 is hung on the top of the fixing plate 402, the first fixing hole 203 and the second fixing hole 4022 will be aligned. At this time, fasteners (such as bolts, screws, etc.) can be used to pass through the first fixing hole 203 and the second fixing hole 4022 in turn, and lock them together. This connection not only provides additional support, but also effectively prevents the hanging buckle part 202 from loosening or falling off due to uneven force or external impact during long-term use, thereby ensuring the stability of the installation of the liquid storage tank 2.
[0045] Optionally, the plate heat exchanger 1 is provided with a second stud 101, and the first support 3 is provided with a second through hole 301 matched with the second stud 101, and the second stud 101 is locked with a second nut after passing through the second through hole 301. The second stud 101 is firmly installed at a proper position of the plate heat exchanger 1, and its length and diameter are accurately calculated and designed to ensure that it can pass through the second through hole 301 on the first support 3 and be locked together with the second nut. Once alignment is completed, the second stud 101 can pass through the second through hole 301 and be locked on the support using the second nut. This connection not only provides strong connection strength, but also effectively resists various external forces and environmental influences, ensuring the stability of the plate heat exchanger 1 in the fixed position.
[0046] It is particularly important to note that by integrating the liquid storage tank 2, the plate heat exchanger 1, the first support 3 and the second support 4 into a compact structural unit, the space utilization is optimized, and the overall aesthetics of the equipment is improved. More importantly, this compact structural unit design improves the overall performance of the system. By reducing the length of the pipeline and the connection points, the fluid resistance of the system is effectively reduced, thereby improving the energy efficiency. At the same time, due to the enhanced synergy between components, the response speed and stability of the system are also significantly improved.
