[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is a further detailed description of the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0026] See also Figures 1-4 As shown, an embodiment of the utility model is an intelligent diesel generator set, including a mounting plate 3, a diesel generator 5 is fixedly connected to the top of the mounting plate 3, a coolant box 6 is provided on the diesel generator 5, a liquid filling cap 7 is threadedly connected to the top of the coolant box 6, and a temperature control component 8 is provided on the mounting plate 3.

[0027] The temperature control component 8 includes a coolant tank 801 arranged on the top of the mounting plate 3, and a water distribution pipe 805 is fixedly connected to the top of the coolant tank 801, and a water pump 804 is fixedly installed on one side of the water distribution pipe 805. The water inlet of the water pump 804 is fixedly connected to the liquid inlet pipe 803, and the liquid inlet pipe 803 is fixedly connected to the coolant box 6. One side of the water distribution pipe 805 is fixedly connected to the heat dissipation pipe 812, and one end of the heat dissipation pipe 812 is fixedly connected to the water collecting pipe 806. The bottom of the water collecting pipe 806 is fixedly connected to the return pipe 807, and the return pipe 807 is fixedly connected to the coolant tank 801. The bottom of the coolant tank 801 is fixedly connected to the connecting pipe 809, and a one-way valve 808 is provided on the connecting pipe 809.

[0028] In the above technical solution, water pump 804 pumps coolant from coolant box 6. The coolant enters heat pipe 812 through water distribution pipe 805, where it exchanges heat with the air, dissipating heat and cooling the coolant. The cooled coolant then flows back into coolant tank 801 through return pipe 807. The low-temperature coolant in coolant tank 801 then flows back into coolant box 6 through connecting pipe 809, continuously cooling diesel generator 5. When the temperature is low, water pump 804 is turned off, preventing the coolant in coolant box 6 from being cooled, thus reducing the viscosity of the engine oil. By turning on different water pumps 804 to cool different diesel generators 5, it is possible to individually control each generator set and ensure that the temperature of each diesel generator 5 remains stable. A protective frame 4 is provided on the surface of the diesel generator 5.

[0029] To better control the temperature within the coolant box 6, a controller 802 is fixedly connected to one side of the coolant tank 801. A temperature sensor 810 is fixedly connected to the coolant box 6. The signal output terminal of the temperature sensor 810 is electrically connected to the signal input terminal of the controller 802. The temperature within the coolant box 6 is detected by the temperature sensor 810 and the temperature information is transmitted to the controller 802. The controller 802 controls the corresponding water pump 804 to turn on and off, and controls the operating power of the water pump 804. The connection and control methods between the controller 802 and the water pump 804 are conventional and will not be described in detail.

[0030] The controller 802 may be an S7-200 ultra-miniaturized PLC controller, and the temperature sensor 810 may be a pt100 temperature sensor.

[0031] To further improve the heat exchange efficiency between heat pipe 812 and the air, cooling fans 813 are symmetrically positioned on top of coolant tank 801, with their bottoms not in contact with tank 801. When fans 813 are activated, they drive air flow, accelerating the air flowing over the surface of heat pipe 812 and improving heat dissipation. Fans 813 are electrically connected to controller 802, allowing them to automatically start and stop.

[0032] To control the temperature of the coolant in the coolant box 6, multiple heat pipes 812 are evenly and fixedly connected to one side of the water distribution pipe 805. Each heat pipe 812 is fixedly connected to a solenoid valve 811. To increase the temperature of the coolant in the coolant box 6, the number of solenoid valves 811 opened is reduced. To decrease the temperature of the coolant in the coolant box 6, the number of solenoid valves 811 opened is increased. By controlling the flow of coolant through the heat pipes 812, the coolant temperature is controlled, keeping the coolant within a suitable temperature range.

[0033] To further improve heat dissipation, the signal output of controller 802 is electrically connected to the signal input of solenoid valve 811, which is in turn electrically connected to the signal input of cooling fan 813. When the coolant temperature is high, cooling fan 813 is activated to accelerate air flow, improve heat dissipation efficiency, and thus lower the coolant temperature.

[0034] In order to reduce noise and vibration, shock-absorbing legs 2 are symmetrically arranged on the bottom of the mounting plate 3, and the bottom of the shock-absorbing legs 2 is fixedly connected to the base plate 1.

[0035] In order to improve the power generation efficiency, the diesel generator 5 is provided with multiple groups, and the coolant box 6 is fixedly connected to the cooling system of the diesel generator 5. The coolant in the coolant box 6 is kept at a suitable temperature to facilitate the operation of the diesel generator 5.

[0036] In summary, when the embodiment of the present invention is used, power is generated by the operation of the diesel generator 5. When the diesel generator 5 is operating, the coolant in the coolant box 6 flows into the diesel generator 5, cooling the diesel generator 5. At this time, the coolant in the coolant box 6 is heated. When the temperature is low, the water pump 804 is turned off and does not cool the coolant in the coolant box 6, causing the coolant box 6 to heat up and reduce the viscosity of the engine oil. When the temperature rises, the water pump 804 pumps the coolant in the coolant box 6 out. The coolant enters the heat dissipation pipe 812 through the water distribution pipe 805, exchanges heat with the air, dissipates heat and cools the coolant. The cooled coolant flows back to the coolant tank 801 through the return pipe 807. The low-temperature coolant in the coolant tank 801 flows back to the coolant box 6 through the connecting pipe 809, continuously cooling the diesel generator 5. When the coolant in the coolant box 6 needs to be heated up, the number of solenoid valves 811 opened is reduced. When the temperature of the coolant in the coolant box 6 needs to be lowered, the number of solenoid valves 811 opened is increased. The temperature of the coolant is controlled by controlling the flow of the coolant flowing through the heat pipe 812, so that the coolant is kept in a suitable temperature range.

[0037] The above shows and describes the basic principles of the present invention. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the scope of protection of the present invention.
