[0056] In order to make the above objectives, features and advantages of the present application more apparent, further detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0057] As shown in Figures 1 to 3 the present application provides a case structure, comprising:

[0058] A case structure for placing a hybrid power system, comprising: a case, a hot space air inlet 1, a hot gas outlet 2, a cold space air inlet 3, a hot space air outlet device 4 and a cold space air outlet device 5, wherein,

[0059] The case is divided into a hot space area 7 and a cold space area 8 by a heat insulation layer 9, and a connecting passage 6 for a first device in the hot space area 7 and a second device in the cold space area 8 is arranged on the heat insulation layer 9, which can be a bearing passage or the like;

[0060] Through the hot space air inlet 1, the hot gas outlet 2 and the hot space air outlet device 4 arranged on the case, external gas can enter the hot space area 7 from the hot space air inlet 1 and be discharged from the hot space air outlet device 4, which ensures the air required for engine combustion in the hot space area 7 and enhances the discharge of internal heat, ensuring the ambient temperature of the hot space area 7;

[0061] Similarly, through the cold space air inlet 3 and the cold space air outlet device 5 arranged on the case, external gas can enter the cold space area 8 from the cold space air inlet 3 and be discharged from the cold space air outlet device 5, which enhances the discharge of internal heat and ensures the ambient temperature of the cold space area 8.

[0062] The hybrid power system comprises: a first device and a second device;

[0063] Preferably, the hot space area 7 can be used to arrange a first device such as an engine, and the cold space area can be used to arrange a second device such as an output motor, and a connecting passage for the engine and the output motor is arranged on the heat insulation layer 9.

[0064] In this embodiment, the enclosure space is divided into a hot space area 7 and a cold space area 8. The hot space area 7 can be used to place high-temperature equipment, such as engines, because engines require fuel gas, so the overall temperature of the hot space area is high. The cold space area 8 can be used to place low-temperature equipment, such as motors. The heat insulation layer can ensure heat isolation and prevent the high temperature of the hot space area from being conducted to the cold space area, thereby affecting the ambient temperature of the cold space area and consequently affecting the low-temperature equipment such as motors placed in the cold space area.

[0065] For example, if the box is rectangular, then the box includes 6 wall panels, namely a top wall, a bottom wall, and 4 side walls connected between the top wall and the bottom wall;

[0066] Here, the material of the enclosure can preferably be a heat-dissipating or heat-conducting material, such as aluminum, aluminum-magnesium alloy, aluminum-lithium, etc., which are easy to transfer and dissipate heat; specifically, 7075 aluminum can be used to make the enclosure; the outer surface of each wall panel of the enclosure can be set as a structure such as heat dissipation teeth or heat dissipation grilles to increase the heat dissipation area, improve the strength of the enclosure, and reduce the weight of the enclosure.

[0067] More preferably, the heat insulation layer 9 can be made of a non-thermal conductive and high-temperature resistant material, such as alumina fiber.

[0068] More preferably, the inner sidewall of the enclosure is provided with sound insulation and / or heat transfer material 10, and each air inlet and exhaust outlet can also be provided with sound insulation and heat transfer material to facilitate sound insulation and heat dissipation; the sound insulation and noise reduction layer formed by the sound insulation material can minimize the conduction and reflection of noise, thereby reducing the noise level.

[0069] like Figure 1 As shown, the thermal space air inlet 1 is disposed on the wall panel of the housing of the thermal space region 7, and guide vanes 11 are disposed around the thermal space air inlet 1, the guide vanes 11 being located within the thermal space region; preferably, the thermal space air inlet 1 is closely attached to the air inlet of the engine with some remaining space:

[0070] Specifically, the external air entering from the hot space air inlet 1 enters the engine through the engine air inlet, and the other part enters the hot space area through the guide vanes 11 to dissipate heat for the equipment in the hot space area 7. It should be noted that the term "closely attached" here means that the hot space air inlet 1 is very close to the engine air inlet, but there is no contact or mechanical connection, which facilitates noise reduction and subsequent mechanical maintenance.

[0071] Preferably, the guide vane 11 is in the shape of a horn, with the smaller opening of the horn connected to the air inlet of the hot space, and the larger opening of the horn far away from the air inlet of the hot space, which facilitates airflow and noise reduction.

[0072] More preferably, the hot space air inlet 1 can also be integrated with a filter screen to filter impurities and particulate matter in the air, protecting internal components such as the engine;

[0074] It should be noted that the close here refers to the hot air exhaust and the exhaust port of the engine are very close, but there is no contact and mechanical connection, which is convenient for noise reduction and subsequent mechanical maintenance;

[0075] Preferably, the hot air exhaust is also provided with a cover plate, which plays a dustproof role. When in use, the exhaust port of the engine can directly pass through the hot air exhaust to exhaust high-temperature gas to the outside of the transportation or transportation equipment. The hot air exhaust can be provided on the wall of the box at the top of the hot space area, which helps to prevent the backflow of high-temperature gas generated by combustion, thereby protecting the engine from damage.

[0076] More preferably, the cover plate of the hot air exhaust can be set as an automatic exhaust cover. The main benefits of the automatic exhaust cover lie in improving safety, optimizing performance, facilitating maintenance and management. The automatic exhaust cover adopts an intelligent control system, which can automatically adjust the opening and closing degree and exhaust volume of the exhaust port according to the actual working state of the engine and the external environmental conditions, and realize precise control.

[0077] Specifically, a controller can be arranged in the cold space area, and a temperature sensor can be arranged in the exhaust port of the engine in the hot space area. The controller can sense the temperature in the exhaust chamber through the temperature sensor. When the temperature rises to a certain degree, the controller can issue an instruction to the motor that controls the operation of the cover plate. The motor can open the exhaust cover plate through the transmission device to allow the exhaust gas to be discharged.

[0078] In addition, when the temperature in the exhaust chamber decreases to a certain level or the user manually operates, the controller can again issue an instruction, and the motor closes the exhaust cover plate through the transmission device to maintain the sealing of the exhaust chamber.

[0079] Hot space exhaust device 4, provided on the wall of the box in the hot space area;

[0080] More preferably, the hot space exhaust device can be optimally arranged near the hot air exhaust to play a jetting role and improve the exhaust effect.

More preferably, the cold, hot space exhaust device can also be equipped with a sound reduction system to reduce the noise generated during exhaust gas emission.

[0088] The cold space air inlet 3 can be arranged at the lower part of the cabinet wall panel on the side of the cold space area,

[0089] In this embodiment, the dustproof louver is used in the integrated design to ensure significant dustproof effect, optimize air circulation, improve reliability and durability, and facilitate installation and maintenance.

[0090] The working principle of the present application is as follows:

[0091] On the side of the hot space area 7, the external air enters the hot space area 7 from the hot space air inlet 1, and then enters the engine through the air inlet of the engine and enters the hot space area through the guide vane 11. The gas in the hot space area 7 is exhausted through the hot space exhaust device 4 to ensure that the exhaust gas can be more smoothly and efficiently exhausted.

[0092] On the side of the cold space area 8, the external air enters the cold space area 8 from the dustproof louver 3, and the gas in the cold space area is exhausted through the cold space exhaust device 5 to ensure that the exhaust gas can be more smoothly and efficiently exhausted.
