A water tank heat exchanger assembly device for automobile

Abstract

The present invention relates to the field of heat exchange technology, specifically to a water tank heat exchanger assembly device for automobiles, comprising a group of rectangular mounting side frames, on which a plurality of groups of heat exchange tubes are movably mounted, and both ends of the heat exchange tubes are provided with rectangular end frames, on which sealed end covers are fixedly mounted, and the sealed end covers are arranged on the side of the rectangular end frames away from the heat exchange tubes. If it is the peak production season, the product output requirements are increased, and the heat generated or required by the reaction will increase at this time. By increasing the number of heat exchange tubes, the heat exchange capacity of the heat exchanger can be increased, thereby effectively transferring or absorbing more heat to meet the higher heat load requirements in the production process. If the number of heat exchange tubes is fixed, the entire heat exchanger may need to be complicatedly repaired or replaced. However, if the number of heat exchange tubes can be adjusted, the damaged heat exchange tubes can be easily disassembled for repair or replacement without large-scale disassembly of the entire heat exchanger.

Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, in particular to a water tank heat exchanger assembly device for an automobile. Background Art

[0002] The automobile radiator heat exchanger assembly is mainly used to cool the automobile engine. The radiator core is the core part, which is the place for heat exchange. Its structure has various forms such as tube-fin type and tube-belt type. The tube-fin radiator core is composed of many cooling water pipes and radiating fins. The cooling water pipes are used for the flow of water, and the radiating fins can increase the heat dissipation area and improve the heat dissipation efficiency.

[0003] If some heat exchange tubes are damaged, such as being corroded, blocked or accidentally ruptured, it is difficult to repair or replace the damaged heat exchange tubes individually due to the fixed number and often integrated structure. Usually, the entire water tank heat exchanger assembly may need to be replaced, which not only increases the maintenance cost, but also may extend the maintenance time of the car. If only one heat exchange tube leaks, it is necessary to purchase a new water tank heat exchanger because it is impossible to replace this tube alone. Moreover, the installation process is relatively complicated, involving multiple steps such as emptying the cooling system and refilling the coolant. The power and heat dissipation requirements of the car engine will vary depending on the car model and engine model. For the water tank heat exchanger with a fixed number of heat exchange tubes, the heat dissipation requirements of the engine need to be accurately matched in the design stage. However, in actual applications, there may be situations where the engine is modified or replaced with an engine of different power. At this time, the fixed number of heat exchange tubes may not be well matched with the heat dissipation requirements of the new engine, resulting in insufficient or excessive cooling of the engine, affecting the normal operation and service life of the engine.

[0012] Preferably, the filter plug is composed of a first filter tube, a second filter tube and a third filter tube, each of which is provided with a guide groove, and each of which is provided with a filter net at an opening position.

[0013] Preferably, heat-conducting fins are provided on the top and the bottom of the heat exchange tube, and one end of the heat-conducting fin is located inside the heat exchange tube and the other end is located outside the heat exchange tube.

[0014] Preferably, a plurality of inclined guide plates are arranged in the heat exchange tube, and the inclined guide plates are sequentially arranged on both sides of the inner wall of the heat exchange tube, and a central fixing rod is arranged between the inclined guide plates for connection.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. According to the needs, install an even number of heat exchange tubes on the rectangular mounting side frame, turn the adjustment bolts on the fixed screw, and fix the side fixing strips through the two adjustment bolts by moving the adjustment bolts on the fixed screw, so as to ensure the rectangular end frame is fixed on the rectangular mounting side frame after adjustment. After the distance between the two rectangular end frames changes, the corresponding outer elastic sleeve and inner elastic sleeve also deform to adapt to the adjustment of the distance between the two rectangular end frames. In automobile production, the heat exchange effect may be adjusted according to the horsepower of the automobile engine. If it is a high-horsepower engine, the heat exchange requirements are increased, and the heat exchange demand will increase at this time. By increasing the number of heat exchange tubes, the heat exchange capacity of the heat exchanger can be increased, so that more heat can be effectively transferred out or absorbed to meet the higher heat load requirements in the production process. If the number of heat exchange tubes is fixed, the entire heat exchanger may need to be repaired or replaced in a complicated manner. However, if the number of heat exchange tubes can be adjusted, the damaged heat exchange tubes can be easily removed for repair or replacement without large-scale disassembly of the entire heat exchanger.

[0017] 2. The liquid entering the filter element contacts the filter screen, and the injected water is filtered through the filter screen. The water flows through the first filter tube, the second filter tube, and the third filter tube in turn. The guide grooves are reduced in size in turn to filter the liquid more delicately. When the liquid enters the heat exchange tube, the inclined guide plate guides and blocks the liquid, allowing the liquid to stay in the heat exchange tube for a longer time. A single filter structure may have a dead corner or fail to effectively remove certain types of impurities. The multi-layer filter structure can make up for the shortcomings of a single filter method through the combination of different filter materials and methods. Some filter layers can remove organic impurities in the water through adsorption, while others can remove inorganic particles through mechanical interception. This synergistic effect can significantly improve the overall filtration effect of the hot water, so that the filtered hot water reaches a higher quality standard. When there is only one layer of filter structure, all impurity interception work is undertaken by this layer, which will cause this layer of filter material to be quickly blocked. The multi-layer filter structure can disperse the task of impurity interception to each filter layer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 14The present invention provides a technical solution: a water tank heat exchanger assembly device for a car, comprising a set of rectangular mounting side frames 1, a groove for mounting a heat exchange tube 2 is provided at the center of the rectangular mounting side frames 1, and the installation and fixation of multiple groups of heat exchange tubes 2 are realized by the cooperation of two rectangular mounting side frames 1. The vertical surface, the horizontal surface and the side surface of the rectangular mounting side frames 1 are grooved to realize the installation of various accessories. Multiple groups of heat exchange tubes 2 are movably installed on the rectangular mounting side frames 1, and rectangular end frames 3 are provided at both ends of the heat exchange tubes 2. The rectangular end frames 3 are provided with grooves corresponding to the ends of the heat exchange tubes 2 to ensure that the liquid in the heat exchange tubes 2 enters the structure composed of the rectangular end frames 3 and the sealing end covers 4. The rectangular end frames 3 can be grooved at the top or the bottom, and are connected through the connecting sleeves 8 and The existence of the outer elastic sleeve 9 structure allows the liquid to be transported into another rectangular end frame 3 and a sealed end cover 4 structure. There are three types of rectangular end frame 3 and sealed end cover 4 structures, no groove, groove on the top or groove on the bottom. The three situations are suitable for different assembly methods. The sealed end cover 4 is fixedly installed on the rectangular end frame 3. The sealed end cover 4 is arranged on the side of the rectangular end frame 3 away from the heat exchange tube 2. The rectangular end frame 3 and the sealed end cover 4 form a cavity to form a space for liquid to flow. Side fixing strips 5 are fixedly installed on both sides of the rectangular end frame 3. The rectangular installation side frame 1 is provided with a control corresponding to the shape of the side fixing strip 5 to adapt to the lifting of the sealed end cover 4. The side fixing strip 5 is movably installed in the rectangular installation side frame 1. According to the required amount of water, select Corresponding to an even number of heat exchange tubes 2, the distance between the structures composed of multiple rectangular end frames 3 and the sealing end covers 4 is adjusted by adjusting the side fixing strips 5 on the fixed screw rods 6 to adapt to the installation of the structures composed of multiple rectangular end frames 3 and the sealing end covers 4. The rectangular installation side frame 1 is vertically fixed with a fixed screw rod 6, and the side fixing strips 5 are movably sleeved on the fixed screw rod 6. The side fixing strips 5 and the fixed screw rod 6 are interference fit to ensure the stable movement of the side fixing strips 5 on the fixed screw rod 6. The fixed screw rod 6 is threadedly installed with multiple adjusting bolts 7. The threads of the multiple adjusting bolts 7 on the fixed screw rod 6 are moved to ensure the fixing effect of the side fixing strips 5 after adjustment. The adjusting bolts 7 are arranged above and At the corresponding position below, the number of the adjusting bolts 7 corresponds to the number of the side fixing strips 5 to ensure the fixing effect of the adjusting bolts 7 on the side fixing strips 5. A connecting sleeve 8 is provided on the near side of the two adjusting bolts 7, and an outer elastic sleeve 9 is provided between the connecting sleeves 8 for fixed connection. An inner elastic sleeve 10 is provided in the structure composed of the connecting sleeve 8 and the outer elastic sleeve 9, and a fixing buckle 11 is fixedly installed on the inner elastic sleeve 10. The fixing buckle 11 is provided at the position where the connecting sleeve 8 and the outer elastic sleeve 9 are connected. The liquid in the structure composed of the rectangular end frame 3 and the sealing end cover 4 moves through the inner elastic sleeve 10 and is injected into the structure composed of the rectangular end frame 3 and the sealing end cover 4 below. Both the outer elastic sleeve 9 and the inner elastic sleeve 10 can be deformed to adapt to the mutual approach of the two rectangular end frames 3.

[0035] The inner elastic sleeve 10 is composed of a part corresponding to the shape of the connecting sleeve 8 and a part corresponding to the shape of the outer elastic sleeve 9. There is a connecting part between the connecting sleeve 8 and the outer elastic sleeve 9. The fixing buckle 11 is set at the corresponding position of the connecting sleeve 8 and the outer elastic sleeve 9. The fixing buckle 11 fixes the inner elastic sleeve 10 to ensure the fixing effect of the inner elastic sleeve 10 in the structure composed of the connecting sleeve 8 and the outer elastic sleeve 9.

[0036] The inner elastic sleeve 10 and the outer elastic sleeve 9 are both ceramic fiber composite pipes, and the outer wall of the outer elastic sleeve 9 and the inner wall of the inner elastic sleeve 10 are both provided with protective coatings. The ceramic fiber composite pipe is a pipe with ceramic fiber as the inner lining and metal or other composite materials wrapped on the outside. Ceramic fiber has good thermal insulation and flexibility, and can be deformed to a certain extent. The composite material of its outer layer provides the necessary mechanical strength, protects the ceramic fiber lining and enhances the overall pressure bearing capacity of the pipe. This composite structure enables the pipe to adapt to certain bending and stretching while maintaining good sealing performance. Ceramic fiber itself is a high temperature resistant material that can withstand high temperatures of up to 1000-1300°C. In the pipeline, the ceramic fiber lining can effectively isolate the heat of high temperature water and prevent heat from dissipating outward, while also protecting the outer structure from the influence of high temperature. This pipeline is particularly suitable for transporting high temperature water, especially in some occasions where heat loss needs to be reduced.

[0037] The outer elastic sleeve 9 and the inner elastic sleeve 10 are designed to be deformable, so as to ensure that the rectangular end frame 3 and the sealing end cover 4 are close to each other. At the same time, the outer wall of the outer elastic sleeve 9 is in contact with the high-temperature gas, and the protective coating on the outer wall of the outer elastic sleeve 9 can increase the service life of the outer elastic sleeve 9. The inner wall of the inner elastic sleeve 10 corresponds to the water for heat exchange, and the protective coating on the inner wall of the inner elastic sleeve 10 can increase the service life of the inner elastic sleeve 10.

[0038] Pre-set installation grooves 101 are provided at corresponding positions on the bottom and top of the rectangular installation side frame 1 to position the installation of the inner elastic sleeve 10 to ensure the installation speed and stability of the inner elastic sleeve 10 .

[0039] The number of heat exchange tubes 2 is an even number, and one end of two adjacent heat exchange tubes 2 on one side is connected by a rectangular end frame 3, a sealed end cover 4, a connecting sleeve 8 and an outer elastic sleeve 9, and one end of two adjacent heat exchange tubes 2 on the other side is also connected by a rectangular end frame 3, a sealed end cover 4, a connecting sleeve 8 and an outer elastic sleeve 9, and only rectangular end frames 3 and sealed end covers 4 are arranged on the ends of the uppermost and lowermost heat exchange tubes 2 on this side, and rectangular end frames 3, sealed end covers 4, connecting sleeves 8 and outer elastic sleeves 9 are arranged between multiple heat exchange tubes 2 for connection, all heat exchange tubes 2 on one side are connected in pairs, and all heat exchange tubes 2 on the other side are connected in pairs, and the uppermost and lowermost heat exchange tubes 2 at this position are not connected by structures for installing related structures for water outlet and water inlet, and the connecting structures on both sides are staggered to ensure that the liquid is transported between multiple heat exchange tubes 2.

[0040] A trapezoidal flow guide tube 12 is fixedly installed on the uppermost and lowermost rectangular end frames 3, a rectangular connector 13 is fixedly installed on the side of the trapezoidal flow guide tube 12 away from the heat exchange tube 2, and a filter 14 is fixedly installed on the side of the rectangular connector 13 away from the trapezoidal flow guide tube 12;

[0041] The filter element 14 is a core component of the heat exchanger for heat exchange and has a filtering function. The filter screen 21 is integrated in the filter element 14 and can be located at the inlet end, outlet end or wrapped around the filter element 14. The structure of the filter layer is diverse. For example, it can be composed of multiple layers of filter screens, arranged in sequence from coarse filtration to fine filtration, or it can be a composite structure containing adsorption materials and filter materials. Its purpose is to intercept impurities in the hot water, such as particles, colloids, microorganisms, etc., to prevent them from entering the heat exchange tube and affecting the heat exchange efficiency or damaging the equipment. The filter screen 21 in this article is set at the water inlet end and the outlet end to achieve a better filtering effect;

[0042] A bellows 15 is movably mounted on one end of the filter element 14 away from the rectangular connector 13, and an internally threaded tube 16 is fixedly mounted on one end of the bellows 15 away from the filter element 14. A sealing cover 17 is movably mounted in the internally threaded tube 16. The sealing cover 17 is opened and removed. The convenience of installation is improved by the design of the bellows 15 and the internally threaded tube 16 rotating to meet different installation needs. The liquid passes through the trapezoidal flow guide tube 12, the rectangular connector 13, the filter element 14, the bellows 15, and the internally threaded tube 16 in sequence, or passes through the internally threaded tube 16, the bellows 15, the filter element 14, the rectangular connector 13, and the trapezoidal flow guide tube 12 in sequence. According to the needs, the liquid can be removed in the rectangular connector 13. An even number of heat exchange tubes 2 are installed on the rectangular mounting side frame 1. After the heat exchange tubes 2 are installed on the rectangular mounting side frame 1, the adjusting bolts 7 on the fixed screw rod 6 are screwed. The adjusting bolts 7 apply pressure to the side fixing strips 5 through the movement of the adjusting bolts 7 on the fixed screw rod 6. The side fixing strips 5 are fixed by two adjusting bolts 7, thereby ensuring that the rectangular end frame 3 is fixed on the rectangular mounting side frame 1 after adjustment. After the position of the rectangular end frame 3 is adjusted, the distance between the two rectangular end frames 3 changes. After the distance between the two rectangular end frames 3 changes, the corresponding outer elastic sleeves 9 and the inner elastic sleeves 10 are also deformed to adapt to the adjustment of the distance between the two rectangular end frames 3.

[0043] A limit ring 18 is fixedly installed on one side of the inner wall of the filter element 14 close to the rectangular connecting piece 13, and a filter plug 19 is movably installed in the filter element 14. Fixed end rings 20 are provided at both ends of the filter plug 19. The filter plug 19 and the fixed end ring 20 form a structure supported at the corresponding position of the limit ring 18. The filter plug 19 and the fixed end ring 20 form a structure supported at the corresponding position of the limit ring 18, and the liquid is filtered through the filter plug 19.

[0044] The filter plug 19 is composed of a first filter tube 1901, a second filter tube 1902 and a third filter tube 1903. The first filter tube 1901, the second filter tube 1902 and the third filter tube 1903 are all provided with a guide groove 1904. The opening positions of the first filter tube 1901, the second filter tube 1902 and the third filter tube 1903 are all provided with a filter screen 21. The sizes of the guide groove 1904 on the first filter tube 1901, the second filter tube 1902 and the third filter tube 1903 are different. The guide groove 1904 is large at one end and small at the other end, and the guide groove 1904 is successively smaller on the first filter tube 1901, the second filter tube 1902 and the third filter tube 1903. The existence of the filter screen 21 realizes sequential filtration to improve the filtering effect of the liquid. The sealing cover 17 is removed, and the corresponding water pipe structure is installed on the internal threaded pipe 16. The injected water enters the bellows 15 and then enters the filter element 14. The liquid entering the filter element 14 contacts the filter screen 21, and the injected water is filtered by the filter screen 21. The water flows through the first filter tube 1901, the second filter tube 1902 and the third filter tube 1903 in sequence, and the liquid is filtered more delicately through the guide groove 1904, which is reduced in size in sequence. When the liquid enters the heat exchange tube 2, the inclined guide plate 23 is used to guide and block the liquid, so that the liquid stays in the heat exchange tube 2 for a longer time. The central fixing rod 24 can improve the installation strength of the inclined guide plate 23 to ensure the strength of the inclined guide plate 23 when it is impacted. When the liquid is discharged, it also passes through the first filter tube 1901, the second filter tube 1902 and the third filter tube 1903 in sequence to filter the precipitation in the liquid. When the hot water enters the filter element 14, it will first pass through the filter screen 21. Larger particles of impurities will be intercepted by the outermost coarse filter screen, and slightly smaller particles of impurities will be intercepted by the inner fine filter screen.

[0045] Heat transfer fins 22 are provided at the top and bottom of the heat exchange tube 2. One end of the heat transfer fin 22 is located inside the heat exchange tube 2 and the other end is located outside the heat exchange tube 2. The presence of the heat transfer fins 22 increases the contact area between the heat exchange tube 2 and the air to improve the heat exchange effect.

[0046] A plurality of inclined guide plates 23 are arranged in the heat exchange tube 2. The inclined guide plates 23 are arranged in sequence on both sides of the inner wall of the heat exchange tube 2. A central fixing rod 24 is arranged between the inclined guide plates 23 for connection. The liquid passes through the plurality of inclined guide plates 23 in sequence. The inclined guide plates 23 block the flow of the liquid and increase the flow time of the liquid in the heat exchange tube 2. The central fixing rod 24 fixes the inclined guide plates 23.

[0047] Working principle:

[0048] Step 1: Remove the sealing cover 17, and install the corresponding water pipe structure on the internal threaded pipe 16. The injected water enters the bellows 15 and then enters the filter element 14. The liquid entering the filter element 14 contacts the filter screen 21, and the injected water is filtered by the filter screen 21. The water flows through the first filter tube 1901, the second filter tube 1902 and the third filter tube 1903 in sequence. The guide groove 1904 is reduced in size in sequence to filter the liquid more finely. When the liquid enters the heat exchange tube 2, the inclined guide plate 23 is used to guide and block the liquid, so that the liquid stays in the heat exchange tube 2 for a longer time. The central fixing rod 24 can improve the installation strength of the inclined guide plate 23 to ensure the strength of the inclined guide plate 23 when it is impacted. When the liquid is discharged, it also passes through the first filter tube 1901, the second filter tube 1902 and the third filter tube 1903 in sequence to filter the precipitation in the liquid.

[0049] Step 2: Install an even number of heat exchange tubes 2 on the rectangular mounting side frame 1 as needed. After the heat exchange tubes 2 are installed on the rectangular mounting side frame 1, turn the adjusting bolts 7 on the fixed screw rod 6. The adjusting bolts 7 apply pressure to the side fixing strips 5 through the movement of the adjusting bolts 7 on the fixed screw rod 6. The side fixing strips 5 are fixed by the two adjusting bolts 7, thereby ensuring that the rectangular end frame 3 is fixed on the rectangular mounting side frame 1 after adjustment. After the position of the rectangular end frame 3 is adjusted, the distance between the two rectangular end frames 3 changes. After the distance between the two rectangular end frames 3 changes, the corresponding outer elastic sleeves 9 and the inner elastic sleeves 10 are also deformed to adapt to the adjustment of the distance between the two rectangular end frames 3.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
