Description

Technical Field

[0001] This utility model relates to the field of enclosed fuel tank technology, and in particular to a heat dissipation structure for an enclosed fuel tank body. Background Technology

[0002] Enclosed fuel tanks are a type of fuel tank design mainly used in the automotive field. Their core feature is that the fuel tank is semi-enclosed or embedded in the vehicle body structure, so that part of the fuel tank is enclosed by a mounting rack on the vehicle body. In the existing technology, most existing enclosed fuel tanks are fixed to the bottom of the vehicle by a mounting rack, and the heat dissipation of the vehicle fuel tank mainly relies on the flow of external ambient air and contact heat dissipation on the surface of the fuel tank.

[0003] When a vehicle is transported for a long time, the fuel pump generates heat, which raises the temperature of the fuel tank. However, due to the vehicle mounting rack, the fuel tank is enclosed, resulting in very little airflow on the surface of the fuel tank and slow air circulation, thus affecting the heat dissipation efficiency. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the fuel tank is enclosed due to the vehicle mounting rack, resulting in very low airflow and slow heat dissipation on the surface of the fuel tank. Therefore, this invention proposes an enclosed fuel tank body heat dissipation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wrap-around fuel tank heat dissipation structure includes a mounting rack for placing the fuel tank. An air inlet pipe is fixedly connected to one side of the mounting rack, an oil inlet pipe is fixedly connected to one side of the fuel tank, and an oil inlet pipe passing through the mounting rack is fixedly connected to one side of the fuel tank. A blower assembly is provided on the top of the mounting rack, and an alarm assembly is provided on the top of the mounting rack.

[0007] As a further embodiment of this utility model, the blower assembly includes a protective shell fixedly connected to the top of the placement rack, a fan fixedly connected to the bottom inner wall of the protective shell, a connecting pipe fixedly connected to one side of the placement rack at the air outlet of the fan, and an exhaust pipe fixedly connected to one side of the protective shell.

[0008] As a further embodiment of this invention, the alarm component includes a temperature sensor fixedly connected to the top of the mounting frame, with the measuring end of the temperature sensor passing through the mounting frame and contacting the oil tank.

[0009] As a further embodiment of this utility model, two connecting blocks are fixedly connected to one inner wall of the placement rack, and two fixing blocks are rotatably connected to one side of the connecting blocks via a rotating shaft. A baffle is fixedly connected to the bottom of the fixing blocks, and one side of the baffle contacts one side of the air inlet pipe.

[0010] As a further improvement of this utility model, a screen is detachably connected to one side of the air inlet pipe by bolts.

[0011] As a further improvement of this utility model, multiple fins are fixedly connected to both the upper and lower sides of the oil tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves preliminary heat dissipation of the placement rack through the cooperation of an air inlet pipe and a screen, solving the problem of excessively high oil tank temperature and difficulty in heat dissipation, effectively improving the service life of the oil tank and greatly reducing hazards.

[0014] 2. This utility model solves the problems of insufficient airflow when the vehicle is not running or insufficient heat dissipation when running by the cooperation of a fan and a connecting pipe, which makes it difficult to dissipate heat from the fuel tank.

[0015] 3. This utility model, through the combined action of a temperature sensor and fins, enables the detection of fuel tank temperature and the enhancement of the fuel tank's heat dissipation surface, thereby improving its heat dissipation efficiency, greatly extending the service life of the fuel tank, and significantly reducing the problem of fuel tank overheating and difficulty in timely detection.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figures 1-3 A wrap-around fuel tank heat dissipation structure includes a placement rack 3 for placing the fuel tank 17. The placement rack 3 is a metal structure inside the vehicle body that wraps the fuel tank. The fuel tank 17 has multiple fixing racks 16 on its outer side.

[0023] An air inlet pipe 4 is fixed to one side of the placement rack 3 by bolts. The air inlet pipe 4 is funnel-shaped. A screen 5 is detachably connected to one side of the air inlet pipe 4 by bolts. The main function of the screen 5 is to prevent external dust and garbage from entering the placement rack 3 and causing unnecessary damage to the placement rack 3. When the screen 5 needs to be replaced, it can be replaced by removing it with bolts.

[0024] Two connecting blocks 18 are fixed to one inner wall of the mounting bracket 3 by bolts. Two fixing blocks 19 are rotatably connected to one side of the connecting block 18 by a rotating shaft. A baffle 20 is fixed to the bottom of the fixing block 19 by bolts, and one side of the baffle 20 is in contact with one side of the air inlet pipe 4. When the vehicle is started, the wind force will gradually increase due to the special funnel shape of the air inlet pipe 4. When the wind force reaches the side of the baffle 20, the wind force will rotate the baffle 20 and the fixing block 19 on the connecting block 18 through the rotating shaft. When not in use, the baffle 20 will rotate through the rotating shaft on the connecting block 18 due to the gravity of the baffle 20, thereby resetting and blocking one end of the air inlet pipe 4.

[0025] In this invention, an oil inlet pipe 11 is bolted to one side of the fuel tank 17, and an oil inlet pipe 2 is bolted to the same side. A blower assembly is located on the top of the mounting frame 3. The blower assembly includes a protective shell 7 bolted to the top of the mounting frame 3. A fan 10 is bolted to the bottom inner wall of the protective shell 7. A connecting pipe 6, communicating with one side of the mounting frame 3, is bolted to the air outlet of the fan 10. An exhaust pipe 9 is bolted to one side of the protective shell 7. This assembly is used when the vehicle is stopped or in adverse weather conditions. When the fan 10 is started, the fan 10 will draw air through the exhaust pipe 9 on one side of the protective shell 7. The drawn air will be continuously transported from the air outlet of the fan 10 into the connecting pipe 6 and into the placement rack 3, thereby achieving airflow cooling of the fuel tank 17. When the vehicle is in motion, the air in the air will be transmitted to the placement rack 3 along the air inlet pipe 4. As the air is continuously transmitted, the air will pass through the bottom of the fuel tank 17 along the placement rack 3, thereby initially cooling the fuel tank 17. The cooled air will slowly accumulate and flow out from the top of the placement rack 3 to both sides.

[0026] In this invention, the top of the placement rack 3 is equipped with an alarm component, which includes a temperature sensor 8 fixed to the top of the placement rack 3 by bolts. The measuring end of the temperature sensor 8 passes through the placement rack 3 and contacts the oil tank 17. The temperature sensor 8 maintains direct contact with the oil tank 17 and can quickly reflect the temperature change inside the oil tank. Once the temperature of the oil tank 17 rises above the preset value, the temperature sensor 8 converts the detected high temperature data into an electrical signal. After receiving the signal, the controller will start the fan 10 to blow air into the placement rack 3. The models of the temperature sensor 8 and the controller can be selected according to the actual situation. For example, the temperature sensor can be selected as the ATS1-82 sensor, and the controller model can be selected as DATA-7311.

[0027] In this utility model, multiple fins 15 are welded on both the upper and lower sides of the oil tank 17. The fins 15 are heat dissipation fins. The fins 15 undergo slight deformation during vibration, which drives the surrounding air to form a turbulent airflow. The surface of the fins 15 is shot-peened to increase the surface hardness to HV300, so as to prevent external substances from affecting the oil tank 17 when the placement rack 3 vibrates.

[0028] Working principle: When needed, when the vehicle is in motion and the fuel tank 17 is hot and requires cooling, airflow is transmitted through the air intake duct 4 to the mounting bracket 3. Due to the funnel shape of the air intake duct 4, the airflow gradually increases. When the airflow reaches one side of the baffle 20, the airflow causes the baffle 20 and the fixing block 19 to rotate on the connecting block 18 via the pivot. As the airflow continues, it passes through the bottom of the fuel tank 17 along the mounting bracket 3, thus providing initial cooling for the fuel tank 17. After cooling... The air will slowly accumulate at the top of the rack 3 and then flow out from both sides. When the vehicle stops or encounters bad weather and the temperature of the fuel tank 17 is too high, the fan 10 is started. The fan 10 will draw air through the exhaust pipe 9 on one side of the protective shell 7. The drawn air will be continuously transported from the air outlet to the connecting pipe 6 and into the rack 3 through the fan 10. When the hot air in the rack 3 reaches a certain level, the hot air will flow out from both sides of the rack 3 due to the continuous air supply in the rack 3, thereby achieving the discharge of hot air.
