An ECU with good heat dissipation

Abstract

This utility model discloses an ECU with excellent heat dissipation, belonging to the field of turbojet engine technology. It includes an ECU housing, an ECU circuit board inside the housing, a heat dissipation pad at the bottom of the ECU circuit board, and a cooling mechanism at the bottom of the heat dissipation pad. The cooling mechanism includes oil passages located at the bottom of the heat dissipation pad, which are connected to a fuel tank and a fuel pump. Before external fuel enters the fuel pump, it first flows into the ECU housing and then passes through the fuel pump. The oil passages inside the ECU housing and the cooling pad at the bottom of the ECU circuit board allow the fuel to carry away most of the heat generated during ECU operation, thus continuously removing the heat generated during ECU operation. This maintains a stable ECU temperature and ensures the normal operation of the ECU circuit board.

Description

Technical Field

[0001] This utility model belongs to the field of turbojet engine technology, and in particular relates to an ECU with good heat dissipation. Background Technology

[0002] The turbojet engine is like the heart of an aircraft, and the ECU is like the brain of the engine. If the ECU fails to function properly, it will directly cause the aircraft to lose control, leading to accidents such as crashes and bombings.

[0003] The electrical energy output by the generator ECU will directly supply the aircraft. Once the ECU stops generating electricity, the aircraft's electrical system will collapse. The ECU generates a lot of heat when generating electricity. If it cannot be dissipated in time, it will cause the ECU to stop working or burn out. Utility Model Content

[0004] The purpose of this invention is to provide an ECU with good heat dissipation to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides an ECU with good heat dissipation, including an ECU housing, an ECU circuit board inside the ECU housing, a heat dissipation pad at the bottom of the ECU circuit board, a cooling mechanism at the bottom of the heat dissipation pad, and an oil passage disposed at the bottom of the heat dissipation pad, the oil passage being connected to an oil tank and an oil pump respectively.

[0006] Before entering the fuel pump, external fuel flows into the ECU housing and then through the pump. After passing through the pump, the fuel, having carried away heat, enters the engine's combustion chamber, where it is also preheated for more complete combustion, improving fuel efficiency. The ECU housing contains fuel passages, and a cooling pad is added to the bottom of the ECU circuit board. As the fuel passes through the ECU, it carries away most of the heat from the circuit board, ensuring that the heat generated during ECU operation is continuously dissipated. This maintains a stable ECU temperature, allowing the circuit board to operate normally.

[0007] Preferably, the ECU housing has an oil inlet and an oil outlet at both ends, the oil inlet and the oil outlet are respectively connected to the oil passage, the oil inlet is connected to the oil tank, and the oil outlet is connected to the oil pump.

[0008] Preferably, the oil passage is arranged around the bottom of the heat dissipation pad.

[0009] Preferably, the ECU housing has multiple heat dissipation outlets at equal intervals on its side wall.

[0010] This utility model discloses the following technical effects: Before external fuel enters the fuel pump, it first flows into the ECU housing and then passes through the fuel pump. After passing through the fuel pump, the fuel, carrying away heat, enters the engine's combustion chamber, where it is also preheated, ensuring complete combustion and improving engine fuel efficiency. The ECU housing is equipped with oil passages, and a cooling pad is added to the bottom of the ECU circuit board. As the fuel passes through the ECU, it carries away most of the heat from the ECU circuit board, ensuring that the heat generated during ECU operation is continuously dissipated by the fuel. This maintains a stable ECU temperature, allowing the ECU circuit board to operate normally. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-4As shown, this embodiment provides an ECU with good heat dissipation, including an ECU housing 1, an ECU circuit board 2 inside the ECU housing 1, a heat dissipation pad 3 at the bottom of the ECU circuit board 2, a cooling mechanism at the bottom of the heat dissipation pad 3, and an oil passage 4 disposed at the bottom of the heat dissipation pad 3, the oil passage 4 being connected to an oil tank and an oil pump respectively.

[0020] Before entering the fuel pump, external fuel flows into the ECU housing 1 and then through the pump. After passing through the pump, the fuel, having carried away heat, enters the engine's combustion chamber, where it is also preheated for more complete combustion, thus improving engine fuel efficiency. The ECU housing contains an oil passage 4, and a cooling pad 3 is added to the bottom of the ECU circuit board 2. As the fuel passes through the ECU, it carries away most of the heat from the ECU circuit board 2, ensuring that the heat generated during ECU operation is continuously dissipated by the fuel. This maintains a stable ECU temperature, allowing the ECU circuit board 2 to operate normally.

[0021] Further optimization of the scheme: the two ends of the ECU housing 1 are respectively provided with an oil inlet 5 and an oil outlet 6. The oil inlet 5 and the oil outlet 6 are respectively connected to the oil passage 4. The oil inlet 5 is connected to the oil tank, and the oil outlet 6 is connected to the oil pump.

[0022] The fuel inlet 5 is connected to the fuel tank, and the fuel in the fuel tank is sent into the fuel passage 4 through the fuel inlet 5 to remove the heat in the ECU. Then the fuel enters the fuel pump through the fuel outlet 6.

[0023] The design is further optimized by routing the oil channel 4 around the bottom of the heat sink 3. This increases the contact area and contact time between the cooling oil and the heat sink 3, extending the heat exchange path. Compared to a straight oil channel 4, the routing structure can more fully absorb the heat from the heat sink 3, improving the heat absorption efficiency per unit volume of cooling oil.

[0024] The design has been further optimized by incorporating heat sinks on the exterior of the ECU housing 1. These heat sinks enhance natural convection heat transfer with the outside air by increasing the surface area, making them particularly suitable for auxiliary cooling under low-load conditions and reducing the energy consumption of the cooling system.

[0025] To further optimize the design, multiple heat dissipation outlets 7 are provided at equal intervals on the side wall of the ECU housing 1.

[0026] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
