Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically to a heat exchanger with self-cleaning function. Background Technology
[0002] With the booming development of the energy storage industry, the volume of electrochemical energy storage is gradually increasing. Temperature control equipment is a crucial component of electrochemical energy storage systems, its main function being to prevent fires caused by battery overheating and to extend battery life. Utilizing heat transfer and cooling principles, temperature control equipment combines multiple heat exchange devices, heat transfer media, and control elements to ensure the energy storage system maintains a constant temperature for the battery and its surrounding environment, achieving cooling. In electrochemical energy storage systems, problems such as battery heat generation and uneven temperature distribution are prone to occur. This not only affects battery performance but may also lead to safety issues. Temperature control equipment plays a critical role in these situations, precisely regulating the temperature of the electrochemical energy storage battery to ensure the system operates at its optimal state, thereby improving battery safety and lifespan.
[0003] Most temperature control products on the market use fans to dissipate heat from their condensers. Since most temperature control systems are used outdoors, the outdoor environment is complex. For example, willow catkins, sand and dust, and white pollution can easily cause blockages in the condenser circulation side, leading to the failure of temperature control products.
[0004] According to CN215337954U, a self-cleaning heat exchanger is disclosed. This technology discloses a self-cleaning heat exchanger, the key technical points of which are: it includes a finned heat exchanger body; a guide pillar is fixedly installed on the upper part of the finned heat exchanger body; a first spring is sleeved on the outer side of the guide pillar; a support plate is movably installed on the guide pillar; an ultrasonic oscillator is fixedly installed at the center of the support plate; a column is fixedly installed on the upper part of the support plate; an mounting plate is fixedly installed on the upper part of the column; a frequency converter is fixedly installed at the center of the mounting plate; a heat dissipation frame is fixedly installed at one end of the mounting plate; several sets of elastic support components are fixedly installed on the upper part of the finned heat exchanger body; and the elastic support components are fixedly connected to the bottom of the support plate. This technology has the technical effect of "stable self-cleaning of the finned heat exchanger body, and elastic support to maintain safety and stability."
[0005] The above solution uses ultrasonic technology to shake off dust from the surface of the heat exchanger. However, its cleaning effect is not ideal when dealing with heavy dust deposits. Furthermore, since the energy of sound waves is relatively limited, its effective range is also limited. Therefore, when faced with a large area of dust covering the surface of the heat exchanger, this solution may need to significantly extend the processing time and increase energy consumption. This not only increases the complexity of the equipment but also increases the cost accordingly. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a heat exchanger with a self-cleaning function. It features a first electric push rod that drives a support rod to rotate several nozzles on the gas delivery pipe, allowing for angle adjustment. This enables the nozzles to blow on different areas of the condenser exterior from top to bottom, effectively cleaning the dirt on the condenser exterior and preventing high-pressure alarms caused by dirt blockage.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger with a self-cleaning function, comprising a liquid cooling unit, a front frame fixed at the front end of the liquid cooling unit, a condenser installed on the inner wall of the front frame, and a cleaning mechanism provided on the liquid cooling unit for cleaning dirt from the outside of the condenser. The cleaning mechanism includes:
[0008] The actuator includes a crossbeam fixed inside one end of the liquid cooler unit, a slide carriage slidably mounted on the crossbeam, an extension tube fixed to the upper end of the slide carriage, a gas delivery pipe rotatably mounted at the front end of the extension tube, a number of equally spaced nozzles mounted on the gas delivery pipe, a support rod fixed to one end of the outer wall of the gas delivery pipe, a shaft fixed to the rear end of the outer wall of the extension tube, a first electric push rod pivotally connected to the shaft and its output end pivotally connected to the lower end of the support rod;
[0009] The gas supply assembly is installed on the liquid chiller unit and is used to provide the gas source;
[0010] The driver component is set on the execution component and is used to control the scaling of the execution component.
[0011] Preferably, the drive assembly includes a bearing fixed to the bottom of the crossbeam, a second electric push rod pivotally connected to the bearing, and the output end of the push rod pivotally connected to the lower end of the carriage.
[0012] Preferably, the drive assembly further includes guide wheels that are rotatably mounted at both ends of the outer wall of the gas pipeline, and the guide wheels are soft rubber wheels.
[0013] Preferably, a window is provided at the upper interior of the front housing, and a cover plate is installed on the upper front surface of the front housing via a hinge.
[0014] Preferably, the air supply assembly includes an air compressor installed at the lower end of the liquid cooling unit, and an air supply pipe installed on the air compressor.
[0015] Preferably, the gas supply assembly further includes a folded flexible hose installed between the upper end of the gas supply pipe and the rear end of the extension pipe. Beneficial effects
[0016] This invention provides a heat exchanger with a self-cleaning function. Compared with the prior art, it has the following advantages:
[0017] 1. When the external surface of the condenser needs cleaning, the drive assembly drives the actuator to extend to the outside of the liquid cooling unit. The gas supply pipe is located above the front of the condenser, and the nozzles face downwards and backwards. The gas supply assembly supplies air so that high-velocity air is sprayed out from several nozzles. At the same time, the first electric push rod drives the support rod to rotate several nozzles on the gas supply pipe to adjust the angle. This allows the nozzles to blow on different areas of the condenser from top to bottom, effectively cleaning the dirt on the outside of the condenser and preventing high-pressure alarms caused by dirt blockage.
[0018] 2. The slide is driven to slide horizontally along the crossbar by the output end of the second electric push rod. At the same time, the slide drives the nozzle on the gas supply pipe through the extension tube. When cleaning, the nozzle on the gas supply pipe extends to the outside of the liquid cooling unit through the window. When not cleaning, it is retracted to the inside of the liquid cooling unit through the window, thus avoiding damage and contamination of the nozzle in the external environment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a heat exchanger with self-cleaning function, including a liquid cooling unit 1, a front shell 2 fixed at the front end of the liquid cooling unit 1, a condenser 3 installed on the inner wall of the front shell 2, and a cleaning mechanism 4 provided on the liquid cooling unit 1 for cleaning dirt on the outside of the condenser 3. The cleaning mechanism 4 includes:
[0026] The execution component 41 includes a crossbeam 411 fixed inside one end of the liquid cooling unit 1. A slide 412 is slidably mounted on the crossbeam 411. An extension tube 413 is fixed to the upper end of the slide 412. A gas delivery pipe 414 is rotatably mounted at the front end of the extension tube 413. Several nozzles 415 are installed on the gas delivery pipe 414. A support rod 416 is fixed to one end of the outer wall of the gas delivery pipe 414. A shaft frame 417 is fixed to the rear end of the outer wall of the extension tube 413. A first electric push rod 418 is pivotally connected to the shaft frame 417 and its output end is pivotally connected to the lower end of the support rod 416.
[0027] The air supply assembly 42 is installed on the liquid cooling unit 1 and is used to provide an air source;
[0028] The drive component 43 is set on the execution component 41 and is used to control the extension and retraction of the execution component 41.
[0029] In this embodiment, when the external surface of the condenser 3 needs cleaning, the drive assembly 43 drives the execution assembly 41 to extend to the outside of the liquid cooling unit 1, and the gas supply pipe 414 is located above and in front of the condenser 3, with the nozzles 415 facing downward and backward. The gas supply assembly 42 supplies gas so that high-velocity air is sprayed out from several nozzles 415. At the same time, the first electric push rod 418 drives the support rod 416 to rotate several nozzles 415 on the gas supply pipe 414 to adjust the angle, so that the nozzles 415 can blow on different areas of the condenser 3 from top to bottom, effectively cleaning the dirt on the outside of the condenser 3 and preventing the condenser 3 from causing a high-pressure alarm due to dirt blockage.
[0030] Specifically, the drive assembly 43 includes a bearing seat 431 fixed to the bottom of the crossbeam 411, on which a second electric push rod 432 is pivotally connected and whose output end is pivotally connected to the lower end of the carriage 412.
[0031] In this embodiment, the slide 412 is driven to slide horizontally along the crossbeam 411 by the output end of the second electric push rod 432. At the same time, the slide 412 drives the nozzle 415 on the air supply pipe 414 through the extension pipe 413. When cleaning, the nozzle 415 on the air supply pipe 414 extends to the outside of the liquid cooling unit 1 through the window 5. When not cleaning, it is retracted to the inside of the liquid cooling unit 1 through the window 5, thus avoiding damage and contamination of the nozzle 415 in the external environment.
[0032] Specifically, the drive assembly 43 also includes guide wheels 433 that are rotatably mounted on both ends of the outer wall of the gas pipe 414, and the guide wheels 433 are soft rubber wheels.
[0033] In this embodiment, when the execution component 41 extends outward from the inside of the liquid cooling unit 1 through the window 5, the gas delivery pipe 414 in the execution component 41 contacts the inner wall of the cover plate 7 through the guide wheel 433, and pushes the cover plate 7 to flip upward and open to avoid motion interference when the gas delivery pipe 414 drives the nozzle 415 to rotate.
[0034] Specifically, a window 5 is provided at the upper part of the interior of the front frame 2, and a cover plate 7 is installed on the upper part of the front surface of the front frame 2 via a hinge 6.
[0035] In this embodiment, after the execution component 41 retracts into the liquid cooling unit 1 through the window 5, the cover plate 7 flips downward by its own gravity, thereby closing the window 5.
[0036] Specifically, the air supply assembly 42 includes an air compressor 421 installed at the lower end of the liquid cooling unit 1, and an air supply pipe 422 installed on the air compressor 421.
[0037] In this embodiment, ordinary air is compressed to a higher pressure by an air compressor 421, thereby generating high-velocity air, which then enters the extension pipe 413 through the air supply pipe 422 via the folded hose 423, and is then sprayed out from several nozzles 415 on the air delivery pipe 414.
[0038] Specifically, the gas supply assembly 42 also includes a folded flexible hose 423 installed between the upper end of the gas supply pipe 422 and the rear end of the extension pipe 413.
[0039] In this embodiment, the air supply pipe 422 and the extension pipe 413 are connected by a folded hose 423, so that when the extension pipe 413 moves, it can drive the folded hose 423 to extend and retract, ensuring that the air supply pipe 422 can supply air to the extension pipe 413 without interfering with the movement of the extension pipe 413.
[0040] The working principle and usage process of this utility model are as follows: First, when the outer surface of the condenser 3 needs to be cleaned, the slide 412 is driven to slide horizontally along the cross frame 411 by the output end of the second electric push rod 432. At the same time, the slide 412 drives the nozzle 415 on the gas delivery pipe 414 through the extension pipe 413, so that the nozzle 415 on the gas delivery pipe 414 extends to the outside of the liquid cooling unit 1 through the window 5.
[0041] Then, ordinary air is compressed to a higher pressure by air compressor 421, thereby generating high-velocity air, which then enters extension pipe 413 from air supply pipe 422 through folded hose 423, and is then sprayed out from several nozzles 415 on air delivery pipe 414.
[0042] Finally, the first electric push rod 418 drives the support rod 416 to rotate several nozzles 415 on the gas pipeline 414 to adjust the angle, so that the nozzles 415 can blow on different areas of the outside of the condenser 3 from top to bottom, effectively cleaning the dirt on the outside of the condenser 3 and preventing the condenser 3 from causing a high-pressure alarm due to dirt blockage.
