Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0054] See also Figures 1 to 13 , the present invention provides a technical solution: Figure 1 and Figure 2 As shown, it includes a cover 2 for protecting and isolating the generator set from dust, and the bottom of the cover 2 is appropriately embedded with a bottom shell 1;

[0055] A generator 3 is provided inside the bottom shell 1, and an external connection plate 4 is fixedly installed on the outside of the generator 3;

[0056] An air filter 5 for purifying and removing dust from the incoming air, the air filter 5 being fixedly mounted on the external plate 4;

[0057] A supercharger 6 is used to compress the air so that more air can enter the cylinder. The supercharger 6 is fixedly mounted on the external plate 4, and its air inlet end is connected to the air outlet end of the air filter 5 through a pipe.

[0058] A heat management mechanism 7 for performing heat control management on the flowing air, the heat management mechanism 7 being arranged in the bottom shell 1;

[0059] A control component 12 is provided inside the bottom housing 1, wherein the control component 12 is used for regulating power;

[0060] A buffer assembly 8 is provided inside the bottom shell 1. The buffer assembly 8 is used to pre-store and process the incoming air to prevent the airflow from being too fast and causing thermal friction with the inner wall of the pipe. The top of the buffer assembly 8 is fixedly connected to the intake manifold 9. The end of the intake manifold 9 away from the buffer assembly 8 is fixedly connected to the diesel engine 10.

[0061] The diesel engine 10 is disposed inside the bottom housing 1 , and an exhaust manifold 11 is connected to an air outlet of the diesel engine 10 . An end of the exhaust manifold 11 away from the diesel engine 10 is connected to the buffer assembly 8 .

[0062] A partition plate is provided inside the buffer assembly 8 , and the partition plate divides the buffer assembly 8 into two cavities.

[0063] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the heat management mechanism 7 includes an air pipe 71, the top end of the air pipe 71 is fixedly connected to the supercharger 6, and the end of the air pipe 71 away from the supercharger 6 is fixedly connected to a housing 72;

[0064] There are two shells 72, and the outer sides of the two shells 72 are fixedly connected with an air inlet pipe and an air outlet pipe, wherein the air outlet pipe is fixedly connected to the buffer assembly 8 and communicates with each other;

[0065] The interior of the shell 72 is provided with a heat dissipation pipe 73, and the bottom of the heat dissipation pipe 73 is provided with a heat dissipation fin 74. There are several heat dissipation pipes 73 and heat dissipation fins 74, which are staggered with each other up and down and completely fill the interior of the shell 72. The air is compressed by the supercharger 6 to allow more air to enter the cylinder of the diesel engine 10. Then the air discharged from the supercharger 6 will enter the shell 72 through the air pipe 71. The interior of the two shells 72 is provided with heat dissipation pipes 73 and heat dissipation fins 74, wherein the air will be discharged outward from the exhaust port of the other shell 72 through the heat dissipation pipe 73, and the heat dissipation fins 74 are used to cool the air inside the heat dissipation pipe 73, thereby performing low-temperature treatment on the air with a certain thermal energy after supercharging, so as to reduce the heat load of the engine, increase the intake volume, and thus increase the engine power.

[0066] A fixed filter 79 is fixedly connected to the outside of the housing 72, wherein the fixed filter 79 is used to filter impurities in the external air flow;

[0067] A temperature adjustment component 75 is fixedly installed on the side of the shell 72 away from the fixed filter 79, and a movable filter 76 is inserted into the interior of the fixed filter 79. A conical hole 77 is provided on the surface of the movable filter 76, wherein the inner diameter of the conical hole 77 facing the air flow is larger than the inner diameter of the other end; the fixed filter 79 plays a role in filtering impurities in the external heat exchange air flow. In other words, the external flowing air will pass through the side of the structure composed of the heat pipe 73 and the heat sink 74. First, the air flow will be filtered by the fixed filter 79, and then the heat sink 74 will be cooled, so as to keep the heat sink 74 at a low temperature and keep cooling the air inside the heat pipe 73.

[0068] The bottom of the movable filter 76 is fixedly connected to a multi-fold strip 78. The flow of air entering the fixed filter 79 has a range of flow that is roughly the same size as the area of ​​the movable filter 76. Therefore, the flow of air will pass through the movable filter 76 and enter the left half of the structure composed of the heat pipe 73 and the heat sink 74. In addition, the surface of the movable filter 76 is provided with a tapered hole 77. The aperture of the tapered hole 77 on the end facing the airflow is larger than the aperture of the other end. At the same time, the tapered hole 77 and the filter holes in the fixed filter 79 overlap, so the movable filter 76 serves to enhance the filtering effect of the fixed filter 79.

[0069] like Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, the buffer assembly 8 includes an extension platform 81, the outer side of the extension platform 81 is fixedly connected to the shell 72, the interior of the extension platform 81 is fixedly installed with a fixing seat 82, the interior of the fixing seat 82 is rotatably installed with a No. 1 flip plate 83, the end of the No. 1 flip plate 83 away from the fixing seat 82 is hinged with a middle support shaft 84, and the side of the middle support shaft 84 away from the No. 1 flip plate 83 is hinged with a No. 2 flip plate 85; the No. 1 flip plate 83, the middle support shaft 84 and the No. 2 flip plate 85 will form a triangular plate shape, so that the airflow will first enter the heat pipe 73 The high-temperature air is cooled, and then impacts and flows along the triangular plate. At the same time, the triangular plate also performs heat exchange and cooling on the airflow. Finally, the airflow will flow back and be discharged outward from the right half of the structure composed of the heat sink 74 and the heat pipe 73. The above operations have the following effects: First, it reduces thermal stress damage and extends the life of the intercooler; second, it makes more full use of the external airflow, which not only increases the cooling treatment of the heat sink 74, but also does not affect the flow treatment of the hot air in the heat pipe 73; third, the horizontal airflow "flushes" the heat sink 74 to reduce dust accumulation.

[0070] The bottom of the extension platform 81 is provided with a bottom through-groove 88, and a sleeve rod 86 is slidably adapted inside the bottom through-groove 88. The outer side of the sleeve rod 86 is fixedly connected to the second flip plate 85, and the bottom end of the sleeve rod 86 is fixedly connected to the multi-folding strip 78;

[0071] Leakage-proof patches 87 are fixedly connected to both sides of the sleeve rod 86 , and one end of the leakage-proof patch 87 away from the sleeve rod 86 is fixedly connected to the inside of the extension platform 81 .

[0072] A U-shaped tube 92 is fixedly installed inside the extension platform 81. The outer end surface of the U-shaped tube 92 is fixedly connected to the guide plate 91. A hollow tube 93 is inserted into the outer side of the U-shaped tube 92. The outer side of the hollow tube 93 is rigid and the inner wall is elastic. A short tube 94 is fixedly connected to the outer side of the hollow tube 93. The end of the short tube 94 away from the hollow tube 93 is fixedly connected to the air bag 95.

[0073] A protective cover 96 is fixedly connected to the outside of the U-shaped tube 92, wherein the protective cover 96 is used to protect the airbag 95;

[0074] A temperature sensor 90 is provided inside the U-shaped tube 92, and an electric push rod 97 is fixedly connected to the outside of the U-shaped tube 92. A control terminal 901 is provided on the outside of the fixed end of the electric push rod 97; similarly, when the temperature inside the U-shaped tube 92 rises again, the electric push rod 97 is used to extend the conical tube 99 outward from the hollow tube 93, and at the same time, the tough airbag 95 will squeeze the cooled coolant back into the hollow tube 93.

[0075] A compensation plate 98 is fixedly connected to the outer side of the output end of the electric push rod 97, and a conical tube 99 is fixedly installed on the end of the compensation plate 98 away from the electric push rod 97, wherein the conical tube 99 and the hollow tube 93 are both filled with coolant, and the outer side of the conical tube 99 is squeezed and adapted to the inner wall of the hollow tube 93. When the temperature inside the U-shaped tube 92 rises, it means that the temperature of the coolant inside the hollow tube 93 has risen. At the same time, the temperature sensor 90 will sense the temperature change, and then the temperature sensor 90 will transmit the electrical signal to the control terminal 901. The control terminal 901 will receive and calculate the electrical signal and drive the electric push rod 97 to contract, so that the electric push rod 97 will be inserted into the hollow tube 93 with the tapered tube 99 through the compensation plate 98. The outer wall of the hollow tube 93 is rigid, and the inner wall is elastic. Therefore, when the tapered tube 99 completely enters the hollow tube 93, the inner wall of the hollow tube 93 will be compressed, and the coolant inside it will be squeezed into the airbag 95 through the short tube 94. The airbag 95 has a certain toughness. Finally, the coolant inside the tapered tube 99 is used to cool the airflow in the U-shaped tube 92, thereby playing a role in cooling alternation to cool the high-temperature airflow.

[0076] When the present invention is in use: first, the outside air is passed into the air filter 5, at this time the air filter 5 will filter the impurities and toxic gases in the air, and then enter the air inlet end of the supercharger 6 through the pipe. At this time, the supercharger 6 will compress the air to allow more air to enter the cylinder of the diesel engine 10, and then the air discharged from the supercharger 6 will enter the shell 72 through the air pipe 71, and the interior of the two shells 72 is provided with a heat dissipation pipe 73 and a heat sink 74, wherein the air will be discharged outward from the exhaust port of the other shell 72 through the heat dissipation pipe 73, and the heat sink 74 is used to cool the air inside the heat dissipation pipe 73, and perform low-temperature treatment on the air with a certain thermal energy after supercharging, so as to reduce the heat load of the engine, increase the intake volume, and thereby increase the power of the engine.

[0077] In addition, a fixed filter 79 is fixedly installed on the outside of the shell 72, and the fixed filter 79 will filter impurities in the external heat exchange airflow. In other words, the external flowing air will pass through the side of the structure composed of the heat pipe 73 and the heat sink 74. First, the airflow will be filtered by the fixed filter 79, and then the heat sink 74 will be cooled to keep the heat sink 74 at a low temperature, and the air inside the heat pipe 73 will be cooled all the time. The left half of the fixed filter 79 is connected to the movable filter 76, and the flow air entering the fixed filter 79 has a range that is generally the same as the area of ​​the movable filter 76. Therefore, the flow air will pass through the movable filter 76 and enter the left half of the structure composed of the heat pipe 73 and the heat sink 74. In addition, a conical hole 77 is provided on the surface of the movable filter 76, and the aperture of the conical hole 77 at one end facing the airflow is larger than the aperture at the other end. At the same time, the conical hole 77 coincides with the filter hole on the fixed filter 79.

[0078] The airflow passing through the movable filter 76 will enter the extension platform 81, and the extension platform 81 contains a triangular plate composed of the No. 1 flip plate 83, the middle support shaft 84 and the No. 2 flip plate 85, and the airflow will first impact the left half of the triangular plate, and then be pulled by the left half of the plate and move to the right half of the plate, and finally reverse back and be discharged outward from the right half of the structure composed of the heat sink 74 and the heat pipe 73. Therefore, the left half of the heat sink 74 will first undergo heat dissipation and cooling treatment, and this part of the heat sink 74 is initially in contact with the high-temperature air in the heat pipe 73, and then the airflow after the cooling treatment of the left half of the heat sink 74 will come into contact with the triangular plate. At this time, the airflow will be cooled by the triangular plate again, and then the shape of the triangular plate will make the airflow reflux and cool the right half of the heat sink 74. This part of the heat sink 74 is in contact with the air with lowered temperature, so the temperature of this part of the heat sink 74 does not belong to the high temperature range.

[0079] When the temperature inside the heat pipe 73 rises, the movable filter 76 is pulled outward, and the multi-fold strip 78 connected to the bottom thereof will move outward accordingly, and carry the sleeve rod 86 outward along the bottom through groove 88. In addition, the outer sides of the sleeve rod 86 are respectively connected to the No. 2 flip plate 85 and the leak-proof patch 87, among which the No. 2 flip plate 85, the middle support shaft 84 and the No. 1 flip plate 83 will be folded, and the extension platform 81 will be connected to the structure composed of the heat sink 74 and the heat pipe 73. Then the U-shaped tube 92 will replace the triangle formed by the No. 2 flip plate 85, the middle support shaft 84 and the No. 1 flip plate 83 to guide the airflow. In addition, a hollow tube 93 is provided inside the U-shaped tube 92, and the hollow tube 93 is filled with coolant. Therefore, the structure of the U-shaped tube 92 will increase the cooling force of the airflow. However, when the temperature inside the U-shaped tube 92 rises, it means that the temperature of the coolant inside the hollow tube 93 has risen. At the same time, the temperature sensor 90 will sense the temperature change, and then the temperature sensor 90 will transmit the electrical signal to the control terminal 901. The control terminal 901 will receive and calculate the electrical signal and drive the electric push rod 97 to contract, so that the electric push rod 97 will be inserted into the hollow tube 93 with the tapered tube 99 through the compensation plate 98. The outer wall of the hollow tube 93 is rigid, and the inner wall is elastic. Therefore, when the tapered tube 99 completely enters the hollow tube 93, the inner wall of the hollow tube 93 will be compressed, and the coolant inside it will be squeezed into the airbag 95 through the short tube 94. The airbag 95 has a certain toughness, and finally the coolant inside the tapered tube 99 is used to cool the airflow in the U-shaped tube 92.

[0080] Similarly, when the temperature inside the U-shaped tube 92 rises again, the electric push rod 97 is used to extend the tapered tube 99 outward from the hollow tube 93, and at the same time, the tough airbag 95 will squeeze the cooled coolant back into the hollow tube 93.

[0081] The air exhausted from the thermal management mechanism 7 eventually enters the buffer assembly 8, and then enters the cylinders of the diesel engine 10 through the intake manifold 9. The cylinders then operate, driving the generator 3 while simultaneously passing exhaust gas through the exhaust manifold 11 into the buffer assembly 8. The buffer assembly 8 is equipped with a thermal insulation plate, dividing its interior into two chambers.

[0082] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
