At present, generator sets used outdoors are generally container generator sets. As shown in fig. 1 and fig. 2, the current container generator set is composed of a shaft fan water tank system 11, an engine 12, a generator 13, a control system 14, a box body 15, an exhaust system 16, and the like. The heat of a radiator of the unit, the heat radiation of an engine, the heat radiation of a generator, the air inflow of the engine, the air inflow of the generator and the like are all ventilated and radiated by a fan water tank system arranged on an engine shaft. The hot wind exhausted by the radiator is collided with the silencing material in the exhaust silencing chamber at the front part of the box body, and then is denoised, and is exhausted from the air outlet at the top of the box body after the direction is changed. In order to meet the heat dissipation requirements of the unit, the fan on the engine shaft is generally large in diameter and large in air volume; when the container generator set with the structure operates, negative pressure in the box body is large, the door is difficult to open, and external wind and sand are sucked into the box body if the container generator set is used in a desert oil-gas field environment; the units need to be separated by a certain distance when used side by side, and mutual influence of air intake and exhaust among the units is prevented.

Wherein, a box door (convenient for installing the box type radiator 24) is arranged at one end part of the box body 21, a first cold air inlet is arranged on the box door, a first hot air outlet is arranged at the top part of the box body 21, and the first cold air inlet and the first hot air outlet are both communicated with the heat dissipation chamber 213; a first air inlet shutter 214 is arranged at the first cold air inlet, and a first air outlet shutter 215 is arranged at the first hot air outlet. A second cold air inlet is formed in the other end of the box body 21, and a second hot air outlet is formed in the top of the box body 21; the second cold air inlet and the second hot air outlet are both communicated with the power generation chamber 212; a second air inlet shutter 216 is arranged at the second cold air inlet, and a cooling fan 217 and an air guide cover 218 are arranged at the second hot air outlet; a noise reduction partition plate structure 219 is arranged on the box body 21 at the second cold air inlet. First air inlet shutter 214, first air outlet shutter 215 and second air inlet shutter 216 all adopt manual structure, and the reliability is high, be difficult to damage, especially low temperature sleet weather, if adopt electronic tripe easily to freeze, force to open and can burn out the insurance.

The generator set 22 includes a common chassis 222, a generator 223 and an engine 224 provided on the common chassis 222, and a control system 221 (control cabinet); the structural composition and operating principles of the generator set 22 are well known in the art and will not be described in detail herein; vibration isolators 225 are provided between the common chassis 222 and the floor of the tank 21. The vibration isolator 225 increases the vibration damping performance of the generator set 22 on the engine 224 and the generator 223 during use, reduces the loss of the generator set 22 and prolongs the service life of the generator set 22.

In this embodiment, the box-type radiator 24 includes a casing 241, and an inside high-temperature heat dissipation unit 243 (which may be referred to as a high-temperature heat dissipation water tank) for connecting with a cylinder liner cooling water pipeline of the generator set 22 and an outside low-temperature heat dissipation unit 242 (which may be referred to as a low-temperature heat dissipation water tank) for connecting with an intercooler cooling water pipeline of the generator set 22 are sequentially arranged in parallel outside an open end of the casing 241; an air inlet 244 corresponding to the first cold air inlet is arranged at the open end of the shell 241, an air outlet corresponding to the first hot air outlet is arranged at the top of the shell 241, and an axial flow fan 245 controlled by the frequency conversion system 23 (frequency converter) is arranged at the air outlet.

Because the shaft fan water tank cooling system is eliminated, the ventilation volume in the power generation chamber 212 is only the heat radiation of the generator 223 and the engine 224 and the air intake volume of the engine 224, and the normal operation of the unit can be met by needing smaller ventilation volume. With the structure, external cooling air directly enters the heat dissipation chamber 213 to cool the outer low-temperature heat dissipation unit 242 and the inner high-temperature heat dissipation unit 243, and is forcibly discharged through the axial flow fan 245 on the shell 241, so that the cooling efficiency is high, and the influence of the temperature rise in the box 21 on the cooling system of the generator set 22 is avoided.

By taking the scheme as an example, the box type radiator 24 axial flow fan 245 has the rated power of 55kW, the operation power is about 20kW when the temperature is low in winter, the operation time is 20h every day in winter according to the calculation of 3 months, the fuel can be saved by 16t, and the indirect economic benefit is about 9 ten thousand yuan.

In this embodiment, the partition 211 is provided with a maintenance door 211 for facilitating the entry of the power generation chamber 212 into the heat dissipation chamber 213; and the partition 211 comprises a first partition board, a second partition board and sound-absorbing cotton filled between the first partition board and the second partition board, so that the purpose of noise reduction can be achieved.

In order to save the installation space of the container generator set on the desert oil-gas field, the structure of the container generator set is further improved. Push-pull access doors 25 are arranged on two sides of the box body 21 corresponding to the power generation chamber 212; a positioning beam 26 for enabling a plurality of container generator sets to be used side by side and closely arranged is arranged below the box body 21; an ascending ladder 27 is detachably arranged at the side part of the box body 21 corresponding to the heat dissipation chamber 213 (when a plurality of units are used side by side, the ascending ladder 27 can be detached); cables for electrical connections are routed from the tray housing 21. A plurality of container generating set units pass through positioning beam 26 and are connected side by side adjacent, and container generating set's air inlet all sets up at box 21 both ends, and it sets up in the top of box 21 to air exhaust, and adjacent use does not influence the ventilation cooling of unit and has saved installation space side by side. And when the side by side use, the push-and-pull access door 25 can form an internal passage, which is convenient for personnel to patrol and examine. When the unit is overhauled, the push-pull access door 25 is detached, the generator set 22 can be directly picked out by a forklift, and the maintenance is convenient.

In order to further improve the performance of the container generator set, the exhaust system of the generator set is further improved. The top of the box body 21 is provided with a secondary muffler 28 communicated with an exhaust pipe of the engine 224; the exterior of the secondary muffler 28 is clad with a rock wool panel assembly (aluminum plate and rock wool); the secondary muffler 28 includes a resistive muffler 281 and a reactive muffler 282 connected in series, the reactive muffler 282 being connected to a tail pipe 283. The use of both resistive muffler 281 and resistive muffler 282 in series can effectively absorb high, medium, and low frequency exhaust noise. The aluminum plate is used for wrapping rock wool and winding on the outer surface of the secondary muffler 28, so that the service life of the muffler can be effectively prolonged.

In order to further enable the container generator set in the embodiment to be suitable for the use in a desert oil-gas environment; the intake manifold of the engine 224 is connected to the desert air cleaner 29. The desert air filter 29 is a two-stage air filter consisting of a multi-cyclone tube type coarse filter and a paper filter element, can filter most of dust, meets the working conditions of desert areas, and prolongs the service life of an engine.
