Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0032] like Figure 1 and Figure 2 As shown, the integrated engine accessory bracket includes a flat housing 1. The housing 1 includes a straight section 2 and an inclined section 3 arranged according to the accessory installation position. A partition plate is fixedly connected to the inner cavity of the housing 1 to separate the straight section 2 and the inclined section 3, and the partition plate divides the inner cavity of the housing 1 into several heat-insulating cavities. An air source 8 is fixed to the outside of the housing 1. The outlet end of the air source 8 is connected to the heat-insulating cavities through an air distribution assembly. The accessory mounting surface of the housing 1 has several air holes 4 that are evenly distributed to each heat-insulating cavity and connect to its inner cavity.

[0033] Accessory mounting brackets 5 are fixedly connected to the accessory mounting surfaces of housing 1 for different accessories.

[0034] Engine mounting brackets 6 are fixedly attached to the engine mounting surface of housing 1, corresponding to the engine surface.

[0035] The engine mounting surface of the housing 1 is provided with an engine heat insulation sticker 7, and the engine heat insulation sticker 7 has a clearance notch to avoid the engine connecting bracket 6.

[0036] Inside the shell 1, several supports are vertically and parallelly fixed to each corresponding heat insulation cavity.

[0037] The air distribution assembly includes a gas distributor 9 connected to the outlet end of the gas source 8. The branch pipes of the gas distributor 9 are respectively connected to the gas supply pipes 11. An air inlet cylinder 12 is fixedly connected to each heat insulation cavity on the side wall of the housing 1. The other end of the gas supply pipe 11 is connected to the air inlet cylinder 12.

[0038] The gas supply pipe 11 is fixed to the side wall of the housing 1 by clamps 13.

[0039] Solenoid valves 10 are respectively installed on the branch pipes of gas distributor 9.

[0040] The inlet of air source 8 extends to the outside of the engine compartment via an extension pipe.

[0041] The accessory mounting bracket 5 is arched, and bolt holes are provided on the top of the accessory mounting bracket 5.

[0042] The engine connecting bracket 6 is L-shaped, and bolt holes are provided at the bottom of the engine connecting bracket 6.

[0043] Ribs are fixed to the side wall of the engine connecting bracket 6.

[0044] Temperature sensors are installed on the accessory mounting surface of housing 1, corresponding to the location of each heat insulation cavity.

[0045] Air source 8 includes an axial flow fan or a high-pressure air pump.

[0046] The air source 8 can be fixed to the accessory mounting surface of the housing 1, or it can be fixed to a position around the engine for use.

[0047] The working principle of this device is as follows:

[0048] The mounting position of the engine is fixed by a number of engine connecting brackets 6 arranged on the housing 1. The engine mounting surface of the housing 1 is provided with an engine heat insulation sticker 7, which can effectively reduce the heat of the engine on the accessory bracket and the heat dissipation of the accessories.

[0049] Accessory mounting brackets 5 are fixedly connected to the accessory mounting surface of the housing 1 to different accessories, so that the corresponding generator, compressor, tension wheel, etc. can be fixed to the accessory mounting brackets 5 for fixing the accessories;

[0050] By extending the air inlet of air source 8 to the outside of the engine compartment via an extension pipe, cold air can be drawn in. The temperature of the corresponding accessory location is detected by a temperature sensor, and the gas distributor 9 is controlled to deliver the gas to the heat insulation cavity of the corresponding accessory by controlling the opening and closing of the solenoid valve 10. The cold air is then blown out evenly through the air blowing hole 4 and exchanges heat with the accessory to dissipate heat and reduce the failure rate of the accessory in high-temperature environments.

[0051] The electronic control methods and principles involved in this invention are well-known in the field, for example:

[0052] This system uses "temperature triggering + airflow control + directional heat dissipation" as its core logic. A temperature sensor monitors the temperature of high-temperature components in the engine compartment in real time. When the temperature exceeds a preset threshold, the controller triggers the corresponding solenoid valve 10. Cool air from the air source 8 is precisely delivered to the heat-insulating cavity of the component via the gas distributor 9. Heat exchange is completed through the air outlet 4, reducing the component's temperature. When the temperature drops back to a safe threshold, the solenoid valve 10 closes, stopping the airflow, thus achieving "on-demand heat dissipation and precise temperature control." The core process is as follows:

[0053] Air intake pretreatment: Air source 8 air intake port extends to the outside of the engine compartment through an extension pipe to draw in ambient cold air (temperature lower than the high temperature zone inside the compartment) to avoid drawing in hot air from inside the compartment and affecting heat dissipation efficiency;

[0054] Temperature monitoring: The temperature sensor is in close contact with the surface of the accessory that needs heat dissipation (such as generator, compressor, solenoid valve 10, etc.) to collect temperature data in real time and transmit it to the controller;

[0055] Logical judgment: The controller presets a safe operating temperature threshold for the accessory (e.g., 80℃) and compares it with real-time sensor data:

[0056] When the temperature is greater than or equal to the threshold: the controller outputs an electrical signal to trigger the corresponding solenoid valve 10 to open.

[0057] When the temperature is less than the threshold: the controller cuts off the electrical signal, and solenoid valve 10 is de-energized and closed;

[0058] Air distribution and heat dissipation: After the solenoid valve 10 is opened, the cold air from the air source 8 enters the heat insulation cavity of the corresponding accessory through the branch pipe of the gas distributor 9, and is blown out through the evenly distributed air holes 4 in the cavity, fully exchanging heat with the surface of the accessory and carrying away the heat.

[0059] Cyclic monitoring: The sensor continuously collects temperature data, and the system repeatedly switches on and off based on temperature changes to maintain the accessory's operation within a safe temperature range.

[0060] Air source components (8 parts): Centrifugal fan / vortex pump. Centrifugal fan (airflow priority: 500-1000 m³ / h), vortex pump (high pressure differential: 0.05-0.1 MPa); DC12V / 24V (compatible with automotive power supply). Provides a continuous flow of cold air. The centrifugal fan is suitable for low-resistance short pipelines, and the pump is suitable for multi-branch / long pipelines.

[0061] The detection component includes a temperature sensor, an NTC thermistor sensor (temperature resistance -40~150℃), and an output analog signal (0-10V). It is mounted close to the surface of the accessory to collect the accessory's temperature in real time, providing a basis for control.

[0062] Control components include a simple controller / PLC (basic model), a small single-chip microcontroller (such as the STM32 basic model), and DC12V power supply; it supports multi-channel sensor signal input and solenoid valve 10 signal output to receive temperature signals, perform threshold comparison, and output solenoid valve 10 on / off commands.

[0063] Pneumatic control components, two-position two-way solenoid valve 10, pneumatic two-position two-way valve (normally closed); DC12V / 24V, pressure 0.1MPa.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
