Description

A full water cooling heat dissipation system and control method for a power generation device Technical Field

[0001] The present invention relates to the technical field of cooling technology for a power generation device on a power generation vehicle, and in particular to a full water-cooling heat dissipation system for a power generation device and a control method thereof. Background Art

[0002] With the development of science and technology and the continuous improvement of people's living standards, the application areas of power generation vehicles are becoming more and more extensive. However, conventional power generation vehicles are large in size and have difficulty entering narrow areas such as old urban areas, township lanes and mountainous areas for emergency power supply, which brings a lot of inconvenience to power supply security work. Power generation vehicles with low height, small size and high power generation have come into being. The high power generation requires a large heat dissipation demand of the power generation system. The ventilation and heat dissipation system layout of power generation vehicles in the existing technology cannot provide sufficient ventilation area and layout space for small power generation vehicles. When the generator set is running, the ventilation area is small, which is not conducive to the timely dissipation of heat from the power generation system, resulting in high temperature alarms and even shutdown failures, which will interrupt the emergency power supply work and cause user dissatisfaction.

[0003] Therefore, it is urgent to design an efficient cooling and heat dissipation system using the limited space of a small power generation vehicle to meet the heat dissipation needs of the high-power generator set in the small power generation vehicle during operation.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the background technology and provide a full water-cooling and heat dissipation system for the generator set of a diesel generator vehicle and a control method thereof. By decomposing the cooling system of the generator set into two independent water-cooling and heat dissipation systems for the generator and the engine, the technical problem of small ventilation area and inability to fully dissipate heat from the generator set is solved.

[0006] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is specifically as follows: a full water-cooled heat dissipation system for a power generation device, including an air inlet 1, an air inlet 2, an air exhaust port, a radiator 1 and a radiator 2 arranged in the power generation vehicle compartment; the interior of the power generation vehicle compartment is also provided with a partition wall 1, a partition wall 2 and a partition wall 3, and the partition wall 1, the partition wall 2 and the partition wall 3 divide the interior of the power generation vehicle compartment into an air inlet compartment 1, an air inlet compartment 2 and an exhaust compartment, and the water-cooled generator and the water-cooled engine are arranged in the air inlet compartment 2, radiator 1 is arranged on the partition wall 1, and radiator 2 is arranged on the partition wall 2, and the radiator 1 and the air inlet 1, as well as the radiator 2 and the air inlet 2 are all arranged relative to each other; it also includes a generator cooling and heat dissipation system, an engine cooling and heat dissipation system and an electrical control system.

[0007] Furthermore, the partition wall 1 is arranged at an angle, and the partition wall 2 and the partition wall 3 are arranged vertically.

[0008] Furthermore, the generator cooling and heat dissipation system is connected in series along the water circulation direction of the water circuit, with water pump 1, radiator 1, water-cooled inverter 1 and regulating valve 1 connected in series from the water outlet of the water-cooled generator, and water-cooled rectifier and regulating valve 2 are connected in parallel between the radiator 1 and the generator set.

[0009] Furthermore, the engine cooling and heat dissipation system is connected in series along its water circulation direction, starting from the water outlet of the water-cooled engine, to water pump 2, radiator 2 and regulating valve 4, and a fuel heater and regulating valve 3 are connected in parallel between radiator 2 and the water-cooled engine.

[0010] Furthermore, the air inlet cabin 1 is located at the lower side of the front end of the car, the air inlet cabin 2 is located at the rear side of the car, the exhaust port is arranged on the top of the power car car, and vents are arranged on both the partition wall 1 and the partition wall 2. The radiator 1 and the radiator 2 are respectively arranged at the corresponding vents. There are two cooling air routes in total. One cooling air route enters the air inlet cabin 2 from the air inlet 1 at the rear side of the car body, then flows through the water-cooled engine and water-cooled generator (taking away part of the surface heat), enters the exhaust cabin through the radiator 1, and is finally discharged from the exhaust port. The other cooling air route enters the air inlet cabin 1 from the bottom of the car body, enters the exhaust cabin after passing through the radiator 2, and is finally discharged from the exhaust port.

[0011] Furthermore, the electrical control system includes an electrical device controller, the input end of the electrical device controller is respectively connected to the output end of temperature sensor 1 of the water-cooled inverter, the output end of temperature sensor 2 of the water-cooled rectifier, the output end of temperature sensor 3 of the water-cooled generator and the output end of temperature sensor 4 of the water-cooled engine, and the control end of the generator controller is respectively connected to the electronic control drive end of radiator 1, the electronic control drive end of radiator 2, the electronic control drive end of regulating valve 1, the electronic control drive end of regulating valve 2, the electronic control drive end of regulating valve 3, the electronic control drive end of regulating valve 4, the electronic control drive end of water pump 1, the electronic control drive end of water pump 2 and the drive end of the fuel heater.

[0012] In order to achieve the above-mentioned object of the invention, the present invention also provides a control method for a full water-cooling heat dissipation system of a power generation device, which is:

[0013] When the generator set is ready to work, if the coolant temperature in the water-cooled engine cooling system is below -5°C, the generator set controller turns on the fuel heater and regulating valve three, then turns on water pump two, and the water-cooled engine cooling and heat dissipation system enters the cooling system heating mode. When the coolant temperature in the heat dissipation system rises to 5°C, the water-cooled engine temperature sensor four feeds back a temperature rise signal to the generator set controller, which then turns on the generator set and turns off the fuel heater and regulating valve three.

[0014] When the generator set is generating electricity, the coolant temperature of the water-cooled engine cooling system is higher than 85°C. The water-cooled engine temperature sensor 4 feeds back a high temperature signal to the generator controller, which then turns on radiator 2 and regulating valve 4, and then turns on water pump 2. The water-cooled engine cooling and heat dissipation system enters the heat dissipation mode. When the coolant temperature is lower than 65°C, the generator controller turns off water pump 2, and then closes radiator 2 and regulating valve 4.

[0015] When the generator set is generating electricity, the temperatures of the water-cooled generator, water-cooled rectifier and water-cooled inverter are normal, and the water pump 1, radiator 1, regulating valve 1 and regulating valve 2 are all in the closed state;

[0016] When the generator set is generating electricity, the water-cooled generator becomes hot. The temperature sensor of the water-cooled generator feeds back a high-temperature signal to the generator controller. The generator controller opens regulating valve 1, regulating valve 2 and radiator 1, and then turns on water pump 1. The cooling and heat dissipation system of the water-cooled generator enters the full-speed heat dissipation operation mode.

[0017] When the generator set is generating electricity, the water-cooled inverter becomes hot, while the water-cooled generator and water-cooled rectifier are at normal temperatures. The water-cooled inverter's temperature sensor 1 feeds back a high-temperature signal to the generator controller, which then opens regulating valve 1 and radiator 1, then water pump 1. Regulating valve 2 is normally closed, and the water-cooled generator cooling and heat dissipation system activates the water-cooled inverter heat dissipation mode.

[0018] When the generator set is working, the water-cooled rectifier becomes hot, while the temperatures of the water-cooled generator and water-cooled inverter are normal. The temperature sensor 2 of the water-cooled rectifier feeds back a high-temperature signal to the generator controller. The generator controller opens the regulating valve 2 and radiator 1, and then turns on the water pump 1. The regulating valve 1 is in the normally closed state, and the water-cooled generator cooling and heat dissipation system turns on the water-cooled rectifier heat dissipation mode.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention decomposes the generator cooling system into two independent water-cooling and heat dissipation systems for the generator and the engine. Each component is integrated with the water channel, which has a good heat dissipation effect and solves the problem of small ventilation area and difficulty in timely heat dissipation in the traditional method.

[0021] 2. The present invention forms two cooling air ducts by rationally designing and arranging the internal structure of the vehicle body. One duct enters from the rear end of the vehicle body, flows through the water-cooled generator and water-cooled engine, passes through radiator 1 and enters the exhaust compartment. The other duct enters from the bottom of the vehicle body, passes through radiator 2 and also enters the exhaust compartment. The two cooling air ducts enhance the ventilation inside the vehicle body and further improve the heat dissipation effect.

[0022] 3. The present invention also provides a control method for a full water-cooled heat dissipation system of a power generation device. By setting up multiple temperature sensors, the monitoring of various components inside the heat dissipation system can be strengthened, and control and judgment can be performed through the power generation device controller. Then, targeted heat dissipation modes are activated through various execution components to further improve the heat dissipation effect, which is conducive to solving the problem of small ventilation area.
