Description

Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to an integrated structure of a solar collector and a heat exchanger, and a hot water device. Background Technology

[0002] Hot water equipment is used to heat cold water to a preset temperature to meet daily hot water needs such as washing, bathing, and kitchen use. Hot water equipment includes electric water heaters, gas water heaters, air source water heaters, and loop heat exchanger solar water heaters.

[0003] In related technologies, hot water equipment, such as loop heat pipe solar water heaters, includes a collector, a heat exchanger, and a water tank. The heat exchanger has independent working fluid channels and water channels. During operation, the collector absorbs solar radiation heat energy, causing the internal phase change working fluid to absorb heat and vaporize to form steam. The steam flows into the working fluid channel of the heat exchanger and exchanges heat with the cold water in the water channel. The liquid working fluid, after releasing heat and condensing, flows back to the collector to complete the cycle. The cold water absorbs the heat released by the working fluid in the water channel to achieve a temperature increase. The heated hot water enters the water tank for storage, thereby continuously heating the cold water.

[0004] However, in order to reduce the space occupied by the heat exchanger and the collector, the heat exchanger and the heat pipe collector are integrated. The excess heat radiated and emitted by the collector is easily absorbed by the low-temperature cold water in the shell-and-tube heat exchanger that has not yet participated in the heat exchange, which raises the initial water temperature of the cold water, reduces the heat exchange temperature difference between the working fluid and the water flow in the heat exchanger, and reduces the heat exchange efficiency. Summary of the Invention

[0005] This application provides an integrated structure of a solar collector and a heat exchanger, as well as a hot water device, to solve the technical problem that when a heat exchanger and a heat pipe solar collector are integrated, the excess heat radiated and emitted by the solar collector is easily absorbed in advance by the low-temperature cold water in the shell-and-tube heat exchanger that has not yet participated in heat exchange, causing the initial water temperature of the cold water to be raised, reducing the heat exchange temperature difference between the working fluid and the water flow in the heat exchanger, and reducing the heat exchange efficiency.

[0006] In a first aspect, this application provides an integrated structure of a solar collector and a heat exchanger, comprising:

[0007] A solar collector, comprising a housing and a heat collection section, wherein the heat collection section is disposed inside the housing;

[0008] A heat exchanger is disposed inside the housing and on one side of the heat collection section;

[0009] A heat insulation component is connected to the heat exchanger and is used to block heat radiation between the heat collector and the heat exchanger.

[0010] In some embodiments, the heat insulation component includes heat insulation cotton or vacuum insulation board, which covers the exterior of the heat exchanger.

[0011] In some embodiments, a protective plate is also included, which covers the exterior of the thermal insulation member.

[0012] In some embodiments, an adjusting member is further included, which is disposed inside the housing and is used to adjust the distance between the heat exchanger and the heat collector.

[0013] In some embodiments, a cushioning pad is also included, which is connected between the adjusting member and the inner wall of the housing.

[0014] In some embodiments, the heat collection unit includes a plurality of parallel heat pipes, and the heat pipes and the heat exchanger form an angle α, where 30°≤α≤60°.

[0015] In some embodiments, a protrusion is provided on the housing extending toward the outside of the housing, the protrusion being used to accommodate the heat exchanger.

[0016] In some embodiments, the device further includes an inlet pipe, an outlet pipe, and a seal, wherein the inlet pipe is connected to the inlet end of the heat exchanger, and the outlet pipe is connected to the outlet end of the heat exchanger.

[0017] The housing is provided with multiple through holes for the corresponding water inlet pipe and water outlet pipe to pass through. The sealing element is connected between the housing and the water inlet pipe and the water outlet pipe, and the sealing element is used to seal the gap between the housing and the water inlet pipe and the water outlet pipe.

[0018] In some embodiments, both the inlet pipe and the outlet pipe are configured as telescopic pipes.

[0019] Secondly, this application provides a hot water device, including a water tank and an integrated structure of a collector and a heat exchanger, wherein the heat exchanger of the integrated structure is connected to the water tank.

[0020] This application provides an integrated structure of a solar collector and a heat exchanger, as well as a hot water device. By employing a heat insulation component, the heat insulation and heat-blocking effect of the component effectively prevents heat radiation and disordered heat transfer from the solar collector towards the heat exchanger. This can, to a certain extent, prevent the low-temperature cold water to be exchanged in the heat exchanger from prematurely absorbing excess heat dissipated from the solar collector, thus maintaining a low initial inlet temperature for the cold water. The heat transfer during the heat exchange process mainly relies on the temperature difference between the hot and cold fluids as the driving condition. When the cold water maintains a low initial temperature, it can relatively increase the temperature difference between itself and the high-temperature phase change working fluid in the heat exchanger. A sufficient temperature difference can enhance the spontaneous heat transfer, accelerate the heat transfer rate from the working fluid to the cold water, increase the heat exchange per unit time, and make the heat exchange between the working fluid condensation and heat release process and the cold water heat absorption and heating process more complete and smooth. This effectively improves the heat exchange conditions of the equipment and thus helps to improve the heat exchange efficiency of the entire hot water device. Attached Figure Description

[0037] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] In related technologies, hot water equipment, such as loop heat pipe solar water heaters, includes a collector, a heat exchanger, and a water tank. The heat exchanger has independent working fluid channels and water channels. During operation, the collector absorbs solar radiation heat energy, causing the internal phase change working fluid to absorb heat and vaporize to form steam. The steam flows into the working fluid channel of the heat exchanger and exchanges heat with the cold water in the water channel. The liquid working fluid, after releasing heat and condensing, flows back to the collector to complete the cycle. The cold water absorbs the heat released by the working fluid in the water channel to achieve a temperature increase. The heated hot water enters the water tank for storage, thereby continuously heating the cold water.

[0040] However, in existing technologies, to reduce the overall structural volume and the installation space occupied by the heat exchanger and collector, the heat exchanger and heat pipe collector are usually integrated into one unit. Under normal heat collection conditions, in addition to supplying heat to the internal phase change working fluid, the collector also continuously radiates and dissipates excess heat. Due to the close distance between the heat exchanger and the collector and the lack of effective thermal insulation, the radiant and dissipated heat from the collector is easily transferred to the heat exchanger area and then absorbed in advance by the cold water to be heated in the water flow channel of the shell-and-tube heat exchanger, which has not yet entered the heat exchange process and is in a low-temperature state. Before this part of the cold water has a proper heat exchange with the high-temperature steam in the working fluid flow channel, the initial water temperature is passively raised, which reduces the inherent heat exchange temperature difference between the phase change working fluid and the flowing cold water inside the heat exchanger. The temperature difference driving force for heat exchange and heat transfer is weakened, and the heat exchange rate and the heat exchange per unit time are affected, ultimately reducing the heat exchange efficiency of the entire hot water circulation system.

[0041] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0042] Combination Figure 1 , Figure 2 and Figure 3 This application provides an integrated structure of a solar collector and a heat exchanger, including a solar collector 100, a heat exchanger 200, and a heat insulation component 300. The solar collector 100 includes a housing 110 and a heat collection section 120, which is disposed inside the housing 110. The heat exchanger 200 is disposed inside the housing 110 and is disposed on one side of the heat collection section 120. The heat insulation component 300 is connected to the heat exchanger 200 and is used to block heat radiation between the heat collection section 120 and the heat exchanger 200.

[0043] By adopting the above technical solution, the integrated structure of the collector and heat exchanger provided in this application, through the use of the heat insulation component 300, can effectively block the heat radiation and disordered heat transfer from the heat collector 120 toward the heat exchanger 200. This can, to a certain extent, prevent the low-temperature cold water to be exchanged in the heat exchanger 200 from prematurely absorbing the excess heat dissipated from the heat collector 120, so that the cold water can maintain a low initial inlet temperature. The heat transfer in the heat exchange process mainly relies on the temperature difference between the hot and cold fluids as the driving condition. When the cold water maintains a low initial water temperature, it can relatively increase the temperature difference between it and the high-temperature phase change working fluid in the heat exchanger 200. Sufficient temperature difference can enhance the driving force of spontaneous heat transfer, accelerate the heat conduction rate of the working fluid to the cold water, increase the heat exchange per unit time, and make the heat exchange between the working fluid condensation and heat release process and the cold water heat absorption and heating process more complete and smooth, effectively improving the heat exchange conditions of the equipment, and thus helping to improve the heat exchange efficiency of the entire hot water equipment.

[0044] In this embodiment, the shell 110 has a rectangular cross-section. In other embodiments, the shell 110 of the collector 100 can also be set as a circular, elliptical, or polygonal cross-section structure. Different shapes of shell 110 can adapt to the contours and layout constraints of different installation spaces, and can better fit the shape and structure of the installation location such as the building roof and balcony, improving the overall installation adaptability and space utilization. At the same time, the irregular cross-section shell 110 can also optimize the internal heat enclosure effect, reduce the loss of internal heat energy to the outside during the heat collection process, and can also adapt to the integrated arrangement requirements of different specifications of heat collection parts 120 and heat exchangers 200, which facilitates the orderly arrangement of internal components and improves the overall structural compactness and application adaptability.

[0045] In this embodiment, the heat exchanger 200 includes an inner tube and an outer tube. The interior of the inner tube is a water channel, and the space between the inner and outer tubes is a working fluid channel. The working fluid outlet of the heat collector 120 is connected to the liquid inlet of the heat exchanger 200, and the working fluid inlet of the heat collector 120 is connected to the liquid outlet of the heat exchanger 200, forming a connected working fluid circulation loop. The water inlet of the heat exchanger 200 is connected to the water outlet of the water tank 800, and the water outlet of the heat exchanger 200 is connected to the water inlet of the water tank 800, forming a complete water circulation loop. After absorbing heat energy, the heat collector 120 heats the internal working fluid, and the high-temperature working fluid flows into the working fluid channel of the heat exchanger 200 through the working fluid outlet. The working fluid exchanges heat with the water in the water channel through the inner tube wall. After releasing heat and cooling down, the working fluid flows back to the heat collector 120 through the outlet of the heat exchanger 200, realizing the circulation of heat absorption and release of the working fluid. The inlet of the heat exchanger 200 is connected to the outlet of the water tank 800, and the outlet of the heat exchanger 200 is connected to the inlet of the water tank 800, forming a complete water circulation loop. The cold water in the water tank 800 flows out from the outlet and enters the water channel through the inlet of the heat exchanger 200. During the flow, it absorbs the heat transferred by the working fluid to achieve heating. The heated water then flows back to the inside of the water tank 800 through the outlet of the heat exchanger 200, continuously completing the water circulation heating process.

[0046] In this embodiment, the inner tube of the heat exchanger 200 is made of stainless steel with excellent thermal conductivity and resistance to water corrosion, which facilitates efficient heat absorption by the water in the water flow channel and is suitable for long-term water supply. The outer tube is made of metal alloy material that is resistant to high and low temperature alternation, resistant to working fluid corrosion and has high structural strength, which can adapt to the working environment of phase change working fluid circulation in the working fluid channel and ensure the long-term reliable operation of the overall heat exchange structure.

[0047] All connecting pipes of the shell-and-tube heat exchanger 200 are made of corrosion-resistant and high-temperature-resistant materials. The pipe joints are assembled by welding or flange connection, which can effectively ensure the connection sealing after multiple pipes are connected and the operational stability of the overall assembly structure.

[0048] The insulation component 300 includes insulation cotton or vacuum insulation board, which covers the outside of the heat exchanger 200.

[0049] By adopting the above technical solution, the heat insulation cotton or vacuum insulation board is wrapped and placed on the outside of the heat exchanger 200, which can effectively block the excess heat radiated and dissipated from the heat collection part 120 to the heat exchanger 200, reduce the heat transfer to the heat exchanger 200 side, and to a certain extent prevent the cold water to be exchanged in the heat exchanger 200 from being preheated, which is conducive to maintaining the initial inlet temperature of the cold water, relatively increasing the heat exchange temperature difference between the working fluid and the water flow, and at the same time reducing the heat loss of the heat exchanger 200 itself, improving the heat utilization rate and the overall heat exchange effect.

[0050] In some embodiments, the heat insulation component 300 may also be any one or a combination of polyurethane heat insulation board, aerogel heat insulation sheet, and ceramic heat insulation pad. These materials all have the characteristics of low thermal conductivity, good heat resistance and strong structural stability, and can also achieve the function of covering and insulating the heat exchanger 200, effectively blocking the heat radiation and conduction between the heat collection part 120 and the heat exchanger 200, and adapting to the heat insulation requirements under the integrated structure.

[0051] In some embodiments, a single piece of heat insulation baffle can be vertically installed between the heat collector 120 and the heat exchanger 200 for physical separation. Alternatively, loose heat insulation filler can be filled in the gap between the two, and a heat insulation coating can be pasted on the relatively mating surfaces. A double-layer heat insulation board structure with an air gap in the middle can also be adopted. Through multiple methods such as solid shielding, filler filling, heat insulation coating, and air gap weakening heat conduction and heat radiation, the heat conduction, radiation, and influence of the heat collector 120 to the heat exchanger 200 can be blocked, thereby achieving heat isolation between the two.

[0052] Combination Figure 2 and Figure 3 The integrated structure of the collector and the heat exchanger also includes a protective plate 400, which covers the outside of the insulation component 300.

[0053] By adopting the above technical solution, the protective plate 400 completely covers the outside of the heat insulation component 300, which can form an all-round protective shield for the inner heat insulation component 300. It can effectively resist external impacts, squeezing, and external force abrasion during installation and assembly, reducing the possibility of damage or deformation of the heat insulation component 300 under external force. At the same time, it can restrain and fix the position of the heat insulation component 300, reducing the phenomenon of heat insulation material shifting, loosening, or even falling off during long-term use. It can also prevent external moisture and dust from entering the interior of the heat insulation component 300, maintaining the stability of the heat insulation performance of the heat insulation component 300 itself, and extending the service life of the heat insulation component 300 and the overall integrated structure.

[0054] In this embodiment, the protective plate 400 is made of stainless steel, aluminum alloy, engineering plastic, or galvanized steel. Stainless steel and aluminum alloy have high structural strength, corrosion resistance, and are not easily rusted or deformed, and have excellent weather resistance for long-term outdoor use. Engineering plastic is lightweight, easy to form, has good insulation and strong anti-aging ability, and is suitable for overall lightweight assembly requirements. Galvanized steel has moderate cost, good rigidity and good rust protection. The protective plate 400 of various materials can firmly cover the heat insulation component 300, and can withstand outdoor sun and rain and environmental corrosion, maintaining its structural integrity and protective function for a long time.

[0055] The integrated structure of the collector and the heat exchanger also includes an adjusting member 500, which is disposed inside the housing 110 and is used to adjust the distance between the heat exchanger 200 and the collector 120.

[0056] By adopting the above technical solution, the adjusting component 500 can flexibly adjust the distance between the heat exchanger 200 and the heat collector 120. This not only allows for matching and assembly of heat exchangers 200 and heat collectors 120 of different specifications and sizes, improving the structural universality and adaptability, but also allows for changing the size of the gap between them according to actual working conditions. This helps to regulate the degree of heat radiation and heat conduction between them, making it easier to control the heat insulation effect. At the same time, it can accurately position the installation position of the heat exchanger 200, ensuring the accuracy of pipeline connection and assembly, relieving structural assembly stress, and making the overall integrated structure installed neatly and reliably. The spacing can also be flexibly adjusted according to the installation space layout, improving the installation adaptability and operational stability of the overall structure.

[0057] In this embodiment, the adjusting member 500 includes a plate 510, a plurality of screws 520 and a plurality of cylinders 530. The heat exchanger 200 is connected to one side of the plate 510, one end of the screw 520 is fixed to the other side of the plate 510, the cylinder 530 is sleeved and threadedly connected to the other end of the screw 520, and the cylinder 530 is rotatably connected to the inner wall of the shell 110.

[0058] By adopting the above technical solution, the cylinder 530, which is rotatably connected to the inner wall of the shell 110, can be rotated to move axially on the screw 520 via threaded transmission. This, in turn, drives the screw 520 and the connected plate 510 to move synchronously, thereby precisely controlling the relative distance between the heat exchanger 200 and the heat collector 120. This threaded adjustment method has a continuous and uniform adjustment stroke and high positioning accuracy, enabling stepless fine adjustment of the distance. It can stably maintain the adjusted distance position without easy deviation or loosening. The overall structure has reliable transmission and convenient operation. It can also adapt to the adjustment needs of the narrow installation space inside the shell 110. At the same time, the distance can be flexibly adjusted according to the actual heat insulation conditions and component assembly tolerances to ensure the heat insulation effect and the assembly accuracy of the pipeline connection.

[0059] In some embodiments, the adjusting member 500 may also adopt a sliding block type, a multi-position snap-fit ​​type, or a gasket stacking type structure; the sliding block type can realize the heat exchanger 200 to slide smoothly and steplessly within a set stroke, with smooth adjustment and stable positioning; the multi-position snap-fit ​​type can realize the spacing to be adjusted quickly at a fixed point, with simple assembly operation and reliable limit; the gasket stacking type can finely adjust the spacing by adding or removing gaskets of different thicknesses, with a simple structure, low cost and easy assembly and adaptation. Multiple adjustment methods can flexibly adjust the spacing between the heat exchanger 200 and the heat collection part 120, adapt to the assembly of different specifications of devices, compensate for installation tolerances, and flexibly control the degree of heat radiation transfer between the two, improving the overall structural adaptability and assembly versatility.

[0060] The integrated structure of the collector and heat exchanger also includes a buffer pad 600, which is connected between the regulating member 500 and the inner wall of the housing 110.

[0061] In this embodiment, the cylindrical body 530 of the adjusting member 500 is rotatably connected to the buffer pad 600, and the cylindrical body 530 is rotatably connected to the inner wall of the housing 110 through the buffer pad 600.

[0062] By adopting the above technical solution, the buffer pad 600 is set between the adjusting component 500 and the inner wall of the shell 110, which can effectively buffer the impact force caused by vibration and pulsation of pipeline medium flow during equipment operation, weaken the transmission of vibration to the shell 110, the heat collection part 120, and the heat exchanger 200, and reduce the overall structural resonance and operating noise. At the same time, the buffer pad 600 can fill the assembly gap, weaken the hard contact friction between the adjusting component 500 and the inner wall of the shell 110, alleviate the structural wear caused by long-term use, and also play a flexible limiting role for the adjusting component 500, reducing the displacement and looseness under operating condition fluctuations, ensuring that the distance between the heat exchanger 200 and the heat collection part 120 remains stable, and maintaining a good heat insulation layout and structural assembly reliability.

[0063] In this embodiment, the buffer pad 600 can be made of rubber, silicone, polyurethane foam, or damping felt. Rubber has good elasticity and mechanical toughness, and can quickly rebound after being deformed under pressure, providing excellent cushioning and vibration reduction, as well as being wear-resistant and durable. Silicone is resistant to high and low temperatures, aging, and is suitable for humid heat exchange working environments, with outstanding insulation and corrosion resistance. Polyurethane foam is soft and has strong deformation energy absorption capacity, which can weaken the transmission of high-frequency vibrations. Damping felt has a dense structure, which can absorb vibration noise and reduce hard impacts. Buffer pads 600 of various materials can play a role in flexible cushioning, vibration reduction and noise reduction, wear prevention, and flexible limiting between the adjusting component 500 and the inner wall of the housing 110, adapting to the long-term operating requirements of the integrated structure.

[0064] like Figure 4 As shown, the heat collection unit 120 includes a plurality of parallel heat pipes 121, and the heat pipes 121 and the heat exchanger 200 form an angle α, where 30°≤α≤60°.

[0065] By adopting the above technical solution, when the heat pipe 121 and the heat exchanger 200 are inclined at an angle of 30°-60°, the condensation reflux and gravity replenishment effect can be optimized, the heat exchange efficiency of the working fluid circulation inside the heat pipe 121 can be enhanced, and different installation space layouts can be adapted to improve the overall heat collection and heat transfer capacity of the heat collector 120 to the heat exchanger 200.

[0066] A protrusion 130 is provided on the housing 110 extending toward the outside of the housing 110, and the protrusion 130 is used to accommodate the heat exchanger 200.

[0067] By adopting the above technical solution, by providing a local protrusion 130 extending only outward from the shell 110 to specifically accommodate the heat exchanger 200, there is no need to increase the overall size of the shell 110. This not only precisely reserves dedicated installation space for the heat exchanger 200, meeting the assembly, positioning, and layout requirements of the heat exchanger 200, but also effectively reduces the overall volume of the shell 110, lowers the amount of consumables and manufacturing costs of the shell 110, and makes the overall structure of the equipment more compact and regular, reducing the occupation of useless space, facilitating the miniaturization design of the whole machine and on-site installation, but also prevents the problems of increased weight and excessive installation space occupation caused by the overall expansion of the shell 110.

[0068] The integrated structure of the collector and heat exchanger also includes an inlet pipe 700, an outlet pipe 710, and a seal 720. The inlet pipe 700 is connected to the inlet end of the heat exchanger 200, and the outlet pipe 710 is connected to the outlet end of the heat exchanger 200. The housing 110 is provided with a plurality of through holes 111 for the corresponding inlet pipe 700 and outlet pipe 710 to pass through. The seal 720 is connected between the housing 110 and the inlet pipe 700 and the outlet pipe 710, and the seal 720 is used to seal the gap between the housing 110 and the inlet pipe 700 and the outlet pipe 710.

[0069] In this embodiment, one end of the inlet pipe 700 is connected to the outlet end of the water tank 800 of the hot water equipment, and the other end of the inlet pipe 700 is connected to the inlet end of the heat exchanger 200. One end of the outlet pipe 710 is connected to the inlet end of the water tank 800, and the other end of the outlet pipe 710 is connected to the outlet end of the heat exchanger 200.

[0070] By adopting the above technical solution, the sealing element 720 is set between the housing 110 and the water inlet pipe 700 and water outlet pipe 710 through the through hole 111. It can effectively seal the assembly gap between the through hole 111 of the housing 110 and the outer wall of the pipe. On the one hand, it can prevent the heat inside the housing 110 from being dissipated to the outside, reduce heat loss, and improve the overall heat exchange efficiency of the integrated structure of the collector 100 and the heat exchanger 200. On the other hand, it can prevent external dust, water vapor, and debris from entering the interior of the housing 110 through the gap, preventing the core components such as the internal heat pipe 121 and the heat exchanger 200 from being contaminated and corroded. At the same time, it can also play a buffering and shock absorption role, reduce the transmission of pipe operation vibration to the housing 110, and improve the overall structural stability and service durability.

[0071] In this embodiment, the sealing element 720 includes a sealing gasket, a clamping nut, and a sealing sleeve. The inlet pipe 700 and the outlet pipe 710 respectively pass through the corresponding through holes 111 of the housing 110. A high-temperature resistant and corrosion-resistant silicone rubber sealing gasket is fitted onto the outside of the inlet pipe 700 and the outlet pipe 710 and conforms to the end face of the through hole 111 of the housing 110. The sealing sleeve is placed between the inlet pipe 700 and the outlet pipe 710 and the inner wall of the through hole 111, providing a smooth transition. The clamping nut is threaded into the inner wall of the through hole 111 of the housing 110, axially pressing the sealing gasket and the sealing sleeve, thus ensuring proper sealing of the inlet pipe 700, outlet pipe 710, and outlet pipe 710. A tight-fitting sealing structure is formed between the water outlet pipe 710 and the through hole 111 of the shell 110. This structure can effectively seal the assembly gap between the shell 110 and the inlet and outlet water pipes 710, prevent the heat inside the collector 100 shell 110 from leaking outward and reduce heat loss. It can also prevent external dust, water vapor and other impurities from entering the shell 110 through the gap, protecting the internal heat exchange components from corrosion and contamination. At the same time, it can isolate the direct hard contact between the inlet water pipe 700, the outlet water pipe 710 and the shell 110, reduce the wear of components caused by vibration and friction, and greatly improve the sealing stability of the pipe penetration position and the service life of the whole machine.

[0072] In some embodiments, the seal 720 may also be an integrated high-temperature resistant silicone rubber sealing plug, an annular sealing ring, or a rubber wire sleeve, which is directly fitted onto the outside of the inlet pipe 700 and the outlet pipe 710 and embedded in the through hole 111 of the housing 110. It relies on the elasticity of the rubber itself to hug the outer wall of the pipe and fit the inner wall of the through hole 111 to achieve an interference seal. There is no need to set a pressure nut and multiple sealing components. The number of parts is small and the assembly process is simple. It can reliably seal the gap between the through hole 111 of the housing 110 and the pipe, prevent internal heat from escaping and external dust and moisture from entering, and buffer the contact friction between the pipe and the housing 110. The structure is simple, the installation is convenient, and the cost is lower.

[0073] Both the inlet pipe 700 and the outlet pipe 710 are designed as telescopic pipes.

[0074] By adopting the above technical solution, both the inlet pipe 700 and the outlet pipe 710 are set as telescopic pipes. This not only allows for flexible adjustment of the installation distance between the water tank 800 and the collector 100 shell 110, adapting to different on-site installation distances and assembly position deviations, but also utilizes its own telescopic compensation performance to buffer the vibration and thermal expansion and contraction deformation generated during equipment operation. This eliminates stress tension caused by rigid pipe connections, preventing loosening, cracking, and leakage at pipe joints. At the same time, it can adapt to alignment errors during installation, reducing the difficulty of assembly alignment and minimizing the need for forced bending of pipes during installation. This effectively improves the sealing performance of pipe connections and the overall installation compatibility, extending the service life of pipes and connection parts.

[0075] The telescopic pipe adopts a bellows pipe, a metal corrugated telescopic pipe, a silicone telescopic straight pipe, a spring-type telescopic hose or a mesh braided pipe; the bellows pipe has a large telescopic stroke and flexible bending, and can adapt to installation misalignment at multiple angles. The metal corrugated telescopic pipe is heat-resistant and pressure-resistant, with high structural strength, and can resist medium pressure and thermal deformation. The silicone telescopic straight pipe is resistant to high and low temperatures, corrosion, and has excellent sealing performance. The spring-type telescopic hose relies on an internal spring to achieve telescopic rebound, which can effectively compensate for the installation distance deviation and the amount of thermal expansion and contraction. The mesh braided telescopic pipe is tensile and anti-twist, and is not easy to deform. All kinds of telescopic pipes can flexibly adapt to the installation distance deviation between the water tank 800 and the housing 110, buffer the running vibration, absorb the deformation stress generated by thermal expansion and contraction, prevent the pipeline interface from being pulled and loosened to leak water, and at the same time reduce the difficulty of assembly alignment, and improve the adaptability and use stability of the pipeline connection.

[0076] In this embodiment, the parts of the water inlet pipe 700 and the water outlet pipe 710 outside the housing 110 are sleeved with a heat preservation pipe. The heat preservation pipe can adopt rubber and plastic insulation cotton, polyurethane heat preservation pipe or silicone foam heat preservation pipe. By sleeving a heat preservation pipe outside the pipe sections of the water inlet pipe 700 and the water outlet pipe 710 located outside the housing 110, it can play a role in heat insulation and preservation for the water flow in the pipeline, effectively reduce the heat exchange between the hot water in the pipeline and the external air, reduce heat loss, reduce heat dissipation, and improve the overall heat collection and heat exchange efficiency. At the same time, it can also prevent dew condensation and dripping on the outer wall of the pipeline due to temperature difference, prevent the surrounding components from being affected by moisture and corrosion, and can also play a role in protecting the pipeline, slowing down aging and noise reduction and buffering.

[0077] The embodiment of the present application also provides a hot water device, which includes a water tank 800 and the integrated structure of the collector and the heat exchanger in any of the above embodiments, and the heat exchanger 200 of the integrated structure of the collector and the heat exchanger is connected to the water tank 800.

[0078] In this embodiment, the hot water device is a loop heat pipe type solar water heater. In other embodiments, the hot water device can also be a pressurized solar water heater, a non-pressurized integrated solar water heater, an air source heat pump water heater or a wall-mounted boiler supporting water storage water heater.

[0079] The hot water equipment provided in this application, through the integrated structure of the collector and the heat exchanger, comprises an adjusting component 500 consisting of a plate 510, multiple screws 520, and multiple cylinders 530. The heat exchanger 200 is connected to one side of the plate 510, one end of the screw 520 is fixed to the other side of the plate 510, and the cylinder 530 is sleeved and threadedly connected to the end of the screw 520 and rotates with the inner wall of the shell 110. When adjusting the distance between the heat exchanger 200 and the collector 120, the cylinder 530 is rotated, and the screw drive drives the cylinder 530 to move axially on the screw 520, thereby driving the plate 510 and the heat exchanger 200 to move as a whole, achieving continuous and precise adjustment of the distance between them. This system can accommodate heat exchangers 200 and collectors 120 of different specifications. 20. Assembly and installation tolerance compensation: After the spacing is adjusted, the heat insulation component 300 set outside the heat exchanger 200 can effectively weaken the heat radiation and heat conduction generated by the heat collector 120 to the heat exchanger 200. It can prevent the low-temperature cold water to be exchanged in the heat exchanger 200 from being preheated to a certain extent, maintain the initial inlet temperature of the cold water, relatively increase the heat exchange temperature difference between the working fluid and the water flow in the heat exchanger 200, and improve the heat transfer driving force and heat exchange efficiency. At the same time, the protective plate 400 covering the outside of the heat insulation component 300 can protect the heat insulation structure from falling off or being damaged. The buffer pad 600 set between the adjusting component 500 and the inner wall of the shell 110 can buffer vibration and stabilize the adjustment spacing, further ensuring the stability of the heat insulation layout and the long-term reliable operation of the whole machine.
