Description

Technical Field

[0001] The present invention relates to the technical field of engine heat dissipation, and in particular to a device and method for improving the heat dissipation capacity of an engine. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The radiator is an important component in the engine cooling system. Its function is to take away the heat of the coolant flowing through the engine, exchange heat with the outside world, and then the cooled medium flows back to the engine to achieve repeated cooling of the engine.

[0004] The radiator mainly includes an upper water chamber (water inlet chamber), a lower water chamber (water outlet chamber), a heat dissipation core, supporting side panels and an air guide cover. The radiator is arranged in the engine compartment, and a cooling fan is arranged between the radiator and the engine. The cooling fan is used to cool the radiator.

[0005] As a crucial component of the engine cooling system, the radiator plays a vital role in maintaining stable engine operation and thermal management. When large-bore engines are installed in mining trucks or agricultural machinery, the harsh operating environment can easily cause dust, straw, and other substances to adhere to the radiator fins, severely impacting the radiator's heat exchange efficiency and potentially causing engine overheating alarms.

[0006] To solve the above problems, existing technologies mainly rely on manual cleaning or, when the radiator is clogged and inefficient, fan reverse rotation to remove attached dust. Some devices also use compressed air to remove attached dust. However, these devices all require manual control of the cleaning time and cannot achieve autonomous cleaning. The inventors have discovered that existing radiator cleaning methods have the following problems:

[0007] The cleaning time is judged manually based on experience. In some cases, the radiator has been overheating and working for a long time without being cleaned in time. If this continues for a long time, the service life of the radiator and the engine will be affected.

[0008] Most existing cleaning methods require stopping the vehicle for cleaning, which is not timely enough;

[0009] Because the radiator temperature is too high, manual cleaning is easy to cause burns. If you do not clean it directly, you need to use other tools on site, which is time-consuming and inconvenient.

[0010] The fan reversal cleaning method also requires controlling the fan, which is complicated to operate. In addition, the cleaning area is mainly the area facing the fan, and other areas cannot be cleaned.

[0011] The nozzle is fixedly arranged on the upper side or the lower side of the fan, and the cleaning area is limited, and only the outer area of the fan can be cleaned. SUMMARY

[0049] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0050] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0051] As introduced in the background, the prior art radiator cleaning means has the problem of not cleaning the radiator in time. In order to solve the above technical problem, the present application provides a device for improving the heat dissipation capacity of an engine.

[0052] Embodiment one

[0053] In a typical embodiment of the present application, referring to Figure 1 Figure 1, a device for improving the heat dissipation capacity of an engine comprises:

[0054] Water temperature sensors 1 are arranged at the water inlet, water outlet and middle region of the radiator flow channel of the radiator 2 respectively;

[0055] A moving mechanism is installed between the cooling fan and the radiator. The moving mechanism comprises an X-direction moving mechanism and a Y-direction moving mechanism. The Y-direction moving mechanism is connected with the X-direction moving mechanism. The Y-direction moving mechanism is connected with the nozzle 4. The nozzle 4 is connected with the gas supply device 5 or liquid supply device.

[0056] A controller is connected with the moving mechanism 3, gas supply device 5 or liquid supply device, and each water temperature sensor. The controller receives the temperature information sent by each water temperature sensor 1, and obtains the difference between the water inlet temperature and the middle region temperature, and the difference between the middle region temperature and the water outlet temperature. If the difference between the water inlet temperature and the middle region temperature is not within the set range (here, the set range refers to the difference being greater than or equal to 2.5-15℃), the controller controls the moving mechanism to move the nozzle between the water inlet of the radiator and the middle region of the radiator flow channel. If the difference between the middle region of the radiator flow channel and the water outlet temperature is not within the set range (here, the set range refers to the difference being greater than or equal to 2.5-15℃), the controller controls the moving mechanism to move the nozzle between the middle region of the radiator flow channel and the water outlet of the radiator.

[0057] The controller also obtains the difference between the water inlet 7 temperature and the water outlet 6 temperature of the radiator. If the difference between the water inlet 7 temperature and the water outlet 6 temperature is not within the set range (here, the set range refers to the difference being greater than or equal to 5-30℃), the controller controls the moving mechanism to move the nozzle between the water inlet and the water outlet of the radiator, so as to realize the overall cleaning of the radiator.

[0058] Need to explain is that the above water inlet temperature and the middle region temperature difference, radiator flow channel middle region and outlet temperature difference should be in the set range, and the water inlet temperature and the outlet temperature difference should be in the set range, which is determined according to the type of radiator.

[0059] It can be understood that the water temperature sensor 1 arranged in the middle region of the radiator flow channel is arranged at the center of the transverse and longitudinal directions of the radiator flow channel, and the water temperature sensor arranged in the middle region of the radiator flow channel is located at the center of the radiator, so that the movement of the moving mechanism along the side of the radiator is divided into two regions.

[0060] Need to explain is that in other examples, two or more water temperature sensors can be arranged at the middle region of the radiator flow channel, and the distance between adjacent two water temperature sensors in all water temperature sensors 1 is the same. When multiple water temperature sensors are arranged in the middle region of the radiator flow channel, the radiator can be divided into multiple regions, and the control of the moving mechanism can be realized according to the temperature difference of the two sides of each region. Thus, according to which region of the radiator the temperature difference between the two ends is less than the required range, the controller controls the moving mechanism to move the nozzle to the side of the corresponding region, and moves within the range of the region, so as to clean the dust and impurities on the surface of the corresponding region of the radiator.

[0061] In this embodiment, the two sides of the X-direction moving mechanism 9 are respectively fixed at the radiator shell, the X-direction moving mechanism includes an X-direction sliding block, the Y-direction moving mechanism 8 is fixed at the X-direction sliding block, the Y-direction moving mechanism is provided with a Y-direction sliding block, and the nozzle is installed at the Y-direction sliding block. The nozzle head of the nozzle is arranged towards the direction of the radiator, so as to effectively ensure the movable range of the sliding block.

[0062] Need to explain is that the Y-direction sliding block is provided with a clamp 10, the inner side of the clamp 10 is matched with the nozzle through concave and convex parts, one half of the clamp is fixed to the Y-direction sliding block, and the clamp is provided with a convex part 11, as shown in Figure 2 The nozzle is circumferentially provided with a concave part matched with the convex part, the nozzle 4 is installed on one half of the clamp, the other half of the clamp is placed, and the clamp is locked through a bolt and a nut.

[0063] Specifically, the X-direction moving mechanism 9 adopts an X-direction screw sliding block mechanism, and the Y-direction moving mechanism 8 adopts a Y-direction screw sliding block mechanism.

[0064] It can be understood that the length of the X-direction moving mechanism 9 is consistent with the length of the radiator 2, and the length of the Y-direction moving mechanism is consistent with the height of the radiator, so as to effectively ensure the range that the nozzle can reach.

[0065] In this embodiment, the X-direction moving mechanism 9 can be provided with two, and the upper and lower two X-direction moving mechanisms are arranged in parallel. The two ends of the Y-direction moving mechanism 8 are respectively installed at the X-direction sliding blocks, and the arrangement of the two X-direction sliding blocks can effectively stably support the Y-direction moving mechanism.

[0066] Specifically, mounting frames are respectively provided on opposite sides of the radiator in the height direction. The mounting frames are specifically L-shaped. One side of the mounting frame is fixedly connected to the side of the radiator shell, and the other side of the mounting frame is fixedly connected to the bottom of the X-direction moving mechanism. The mounting frame is fixedly connected to the end of the X-direction moving mechanism, and the two ends of the X-direction moving mechanism are fixed by the mounting frames.

[0067] In addition, the device also includes an isolation cover, which is door-shaped and installed on the top and both sides of the moving mechanism. The isolation cover is connected to the radiator shell by welding or bolts. The isolation cover effectively prevents impurities from falling from the top or side to the moving mechanism. The bottom of the isolation cover can be fixedly connected to the mounting bracket on the bottom side.

[0068] In other examples, the isolation cover is a frame-shaped part, and the peripheral sides of the isolation cover are respectively connected to the corresponding sides of the radiator shell. Multiple mesh holes can be set at the bottom of the isolation cover. The setting of the mesh holes is conducive to ventilation and heat dissipation. The inner diameter of the mesh holes is usually smaller than the size of impurities in the working environment to prevent larger impurities from falling on the moving mechanism. Even if there are impurities, they are small impurities, and the dust will not have much impact on the movement of the moving mechanism.

[0069] The air supply device or the liquid supply device is installed in the engine compartment, and the air supply device or the liquid supply device is connected to the nozzle via a hose. In some examples, when the liquid supply device is provided, the liquid supply device stores liquid such as water, and the liquid supply device is provided with a pump body, which is connected to the controller.

[0070] In other examples, refer to Figure 3 As shown, when an air supply device 5 such as an air compressor (referred to as air compressor) is provided, the air compressor is provided in the engine compartment, and a switch is provided at the corresponding hose. The switch is specifically a solenoid valve, and the switch is connected to the controller; when compressed air is used to clean the radiator, the nozzle sprays 3 times in one second at the same position, and the pressure and inertia are used to clean the dust and impurities. In this way, when the heat dissipation efficiency of the radiator is reduced, the dust and impurities attached to the radiator fins are blown away by the high-pressure airflow, thereby restoring the heat dissipation performance of the radiator.

[0071] It should be noted that the controller may be a PLC controller or other types of controllers, and the controller may also be the vehicle's master controller (ECU).

[0072] According to the division of the transverse region between the two adjacent water temperature sensors, the controller sets a plurality of programs, each program corresponds to a divided region, and if the temperature difference on both sides of a region is greater than a set value, the controller controls the execution of the corresponding program. Specifically, the X-direction moving mechanism first drives the Y-direction moving mechanism to move to one side of the corresponding region from the starting position, and then the Y-direction moving mechanism drives the nozzle to move along the height direction of the radiator for a single time or reciprocatingly. During the movement, the radiator is cleaned by the nozzle working. After a set time, the X-direction moving mechanism moves a set distance within the region, and the cleaning by the nozzle continues until the X-direction moving mechanism moves to the other side of the corresponding region and the cleaning by the nozzle is performed. If the temperature difference of a plurality of regions is greater than the set value, the controller executes the corresponding program in sequence.

[0073] The device provided in the embodiment is provided with water temperature sensors at the water inlet, water outlet and middle region of the radiator flow channel of the radiator, each water temperature sensor is connected with the controller, the controller receives temperature information to obtain a temperature difference to control the movement of the moving mechanism, so as to drive the nozzle to spray liquid or gas to the radiator to clean the dust and impurities on the surface of the radiator. The device does not need to be cleaned by manpower at random time. The regions of the radiator are limited by the water temperature sensors, two adjacent water temperature sensors limit a region, and the movement of the moving mechanism is controlled according to the temperature difference at both ends of the region. The radiator fin can be automatically cleaned, without additional cleaning liquid and manual cleaning, and the cleaning efficiency is improved. The device has a wide range of applications, and can be used in engineering machinery, agricultural harvesting machinery and other harsh environments.

[0074] Embodiment Two

[0075] The difference between the embodiment and the embodiment one is that:

[0076] The nozzle is swingably installed at the Y-direction sliding block, the nozzle is connected with the swing motor, the swing motor is connected with the controller, the nozzle can swing in the transverse direction or the longitudinal direction or the oblique direction, the swing of the nozzle is controlled by the controller, and the swingable nozzle can swing at a point to ensure the cleaning range and further improve the cleaning efficiency.

[0077] Embodiment Three

[0078] The embodiment provides a method for improving the heat dissipation capacity of an engine, and adopts the device for improving the heat dissipation capacity of the engine in the embodiment one or the embodiment two.

[0079] Specifically, the following contents are included:

[0081] Water temperature sensors are arranged at the water inlet, water outlet and middle region of the radiator flow channel respectively;

[0082] The moving mechanism, air or liquid supply device and water temperature sensors are connected with the controller respectively;

[0083] The controller receives the temperature information sent by the water temperature sensors, and obtains the difference between the water inlet temperature and the middle region temperature, and the difference between the middle region temperature and the water outlet temperature.

[0084] Reference Figure 4 As shown in the figure, the controller first obtains the engine operating state, determines that the engine is in operation, and obtains the difference between the radiator water inlet 7 temperature T1 and the water outlet 6 temperature T2.

[0085] If the water inlet temperature of the radiator increases, and then the water outlet temperature also increases, but the difference between the two remains unchanged within the set range, the controller determines that the engine is overheated, and an engine overheating alarm is performed.

[0086] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application.
