Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a special vehicle multi-combination radiator. Background Technology

[0002] Special vehicles (such as military off-road vehicles, fire and rescue vehicles, heavy engineering special vehicles, explosion-proof special operation vehicles, etc.) operate in extremely challenging environments. They not only need to operate continuously in extreme climates such as high-temperature deserts and high-altitude mountains, but also need to withstand high-load operations and strong vibrations and impacts for a long time. They also frequently travel in environments with many impurities such as sand and mud. This places stringent requirements on the reliability of the heat dissipation system and its environmental adaptability.

[0003] In existing special vehicle radiator technologies, the intercooler, as a core heat dissipation component, directly affects engine power output and fuel economy due to its operational stability. However, special vehicles often operate in harsh environments such as sandstorms and mud, and the intercooler easily carries a large amount of dust, mud, and other impurities during the intake process. Long-term accumulation of these impurities can clog the core channels, leading to a significant decrease in intake cooling efficiency. In severe cases, it can even cause engine power loss and increased fuel consumption. More importantly, traditional intercoolers generally lack an effective self-cleaning mechanism and cannot deal with the problem of impurity accumulation on their own. They need to be manually disassembled and cleaned regularly, which not only results in short maintenance cycles and high operational difficulty but also significantly increases the operating costs and maintenance burden of special vehicles.

[0004] Therefore, there is an urgent need to improve the multi-combination radiator for special vehicles in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a special multi-combination radiator for vehicles. By installing an air filter inside the radiator's air outlet chamber, the air entering through the air outlet pipe is filtered to intercept dust and impurities mixed in with the air. When cleaning is required, a miniature air pump integrated at one end of the air outlet chamber is started. At the same time, the air pump drives the sealing plate to rotate and block the air outlet pipe. The intercooler core fins are cleaned in a directional manner through reverse pulse air blowing. At the same time, the solenoid valve is opened to discharge the accumulated dust intercepted by the air filter from the tail end outlet, realizing the autonomous cleaning and discharge of impurities.

[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] like Figures 1-6As shown, the special vehicle multi-combination radiator provided in this embodiment includes a radiator assembly 1, which includes an intercooler 2 and a water radiator 3 fixedly installed on the bottom side of the intercooler 2. The intercooler 2 includes an exhaust chamber 21, an intake chamber 22, and an intercooler core 23. An exhaust pipe 210 is fixedly installed on the exhaust chamber 21, and a micro air pump 211 is fixedly installed at one end. A sealing plate 212 corresponding to the exhaust pipe 210 is rotatably installed inside the exhaust chamber 21. An intake pipe 220 is fixedly installed on the upper side of the intake chamber 22, and a solenoid valve 221 is provided on the intake pipe 220. An air filter 222 is fixedly installed inside the intake chamber 22. The intake pipe 220 communicates with the exhaust chamber 21 through the intake chamber 22, the intercooler core 23, and the exhaust pipe 210. The micro air pump 211 and the solenoid valve 221 are connected in series to an external power circuit. The air filter element 222 in the air intake chamber 22 can filter the intake air and intercept dust and impurities. During cleaning, the micro air pump 211 is started to drive the sealing plate 212 to block the air outlet pipe 210. The fins of the intercooler core 23 are cleaned in a directional manner by reverse pulse blowing. At the same time, the solenoid valve 221 is opened to discharge the accumulated dust intercepted by the air filter element 222 from the outlet, realizing the autonomous cleaning and discharge of impurities. The micro air pump 211 can be set to start at a time for timed dust cleaning. The reverse pulse blowing can prevent dust from sticking to the S-shaped filter screen 6 of the air filter element 222, forming triple protection and greatly extending the maintenance cycle of the radiator.

[0019] Furthermore, such as Figures 1-5 As shown, a fan assembly 4 is fixedly mounted on the radiator assembly 1, with an air guide shroud 5 at its upper end. The water radiator 3 is arranged in series with the intercooler and operates by the engine-driven fan assembly 4. Load cooling is achieved through forced convection, and the air guide shroud 5 prevents airflow loss and improves heat dissipation capacity. The water radiator 3 includes a water-cooled core 31 and water chambers 32 fixedly mounted on both sides. An expansion tank 33 is fixedly mounted on the side of the water-cooled core 31, and inlet and outlet water pipes 34 are fixedly mounted on the upper end. Both the water-cooled core 31 and the intercooler core 23 use aluminum fins. The water-cooled core 31 is a plate-fin crossflow design. The water-cooled core 31 is welded in the middle for load heat exchange, and water chambers 32 and inlet and outlet water pipes 34 are welded on both sides for connecting pipes. The expansion tank 33 is made of aluminum sheet metal bent and welded. It is equipped with a water inlet 331, an air inlet and outlet pipe 332 and a liquid level sensor 333. Water pipes 334 are fixedly connected to both ends and are connected to the water chambers 32 on both sides of the water-cooled core 31 through the water pipes 334. The water radiator 3 provides the diesel engine with coolant that meets the temperature and flow requirements to ensure the normal operation of all equipment; the intercooler 2 reduces the temperature of the turbocharged air to the target required temperature to ensure that the air enters the engine at a suitable temperature; the expansion tank 33 provides coolant and venting for the water system to ensure stable pressure throughout the cooling system; a liquid level observation window is provided at its upper end, covering the middle 2 / 3 of the expansion tank's height, allowing the internal liquid level to be observed through the viewing glass; the liquid level sensor 333 is located at 1 / 3 of the expansion tank's height, and when the liquid level in the expansion tank is lower than this height, the liquid level sensor 333 will alarm to remind the driver to add water; Expansion tank volume calculation: The engine coolant volume is 4.185L, the high-temperature water distribution volume is 10.49L, the piping volume is 2L, the total volume of the high-temperature section is 4.185 + 10.49 + 2 = 16.675L, and the high-temperature expansion tank volume is 16.675 × 16% = 2.67L.

[0020] Furthermore, such as Figures 1-5 As shown, the sealing plate 212 is generally driven to rotate by a cylinder (not shown in the figure), or it can rotate naturally downwards by its own gravity. When the micro air pump 211 is started, it blows the sealing plate 212 up, and together with magnets and other related parts, it blocks the air outlet pipe 210. During the rotation, the air outlet pipe 210 is sealed. Several evenly distributed S-shaped filter screens 6 are fixedly installed inside the air filter element 222, which can increase the dust interception area. The valve stem 7 is slidably set inside the solenoid valve 221. The Z-shaped valve core 8 is fixedly connected to the valve stem 7. The air inlet pipe is quickly opened and closed by sliding the Z-shaped valve core 8, which is used to discharge accumulated dust during cleaning.

[0021] like Figures 1-6 As shown, the principle of the special vehicle multi-combination radiator provided in this embodiment is as follows: The water radiator 3 provides the diesel engine with coolant that meets the temperature and flow requirements to ensure the normal operation of all equipment; the intercooler 2 reduces the temperature of the turbocharged air to the target required temperature to ensure that the air enters the engine at a suitable temperature; the expansion tank 33 provides coolant and exhaust for the water system to ensure stable pressure of the entire cooling system. During cleaning, the micro air pump 211 is started to drive the sealing plate 212 to block the exhaust pipe 210, and the intercooler core 23 fins are cleaned in a directional manner by reverse pulse air blowing. At the same time, the solenoid valve 221 is opened to discharge the dust intercepted by the air filter 222 from the exhaust port, realizing the autonomous cleaning and discharge of impurities; the air filter 222 performs pre-filtration, and the micro air pump 211 can be set to start at a time for timed dust cleaning.
