Referring to fig. 1, the present embodiment provides a cooling apparatus for a vehicle, including:

and a pump 500 connected to the nozzle 300, wherein the pump 500 is used for driving the nozzle 300 to spray a cooling medium when the temperature of the heat sink 100 reaches a first set temperature value.
The first set temperature value here may be higher than 41 deg.c, for example the first set temperature value may be in the interval 42 deg.c to 60 deg.c.
The cooling medium may be a coolant, high-temperature compressed air, transmission oil, transfer case oil, or the like.
In addition, the nozzle 300 may spray the atomized cooling medium, and the atomized cooling medium may be mixed with air to absorb heat to lower the temperature of the air around the heat sink 100.
In addition, the heat dissipating devices 100 may be a plurality of devices, such as a coolant radiator, an intercooler, a transmission oil radiator, a transfer case oil radiator, and the like, and each heat dissipating device 100 may be provided with a nozzle 300, a pump 500, and a first temperature sensor 400, so that each nozzle 300 independently performs spray heat dissipation on the corresponding heat dissipating device 100.
Of course, it is also possible that the above-mentioned various heat sinks are integrated together, and the spray heat dissipation is performed only by one nozzle 300, one pump 500 and one first temperature sensor 400, which will be described in detail later in this embodiment. And the two arrangements can be selected according to the actual needs of the vehicle.
The powertrain 200 here includes an engine, a transmission, a transfer case, and the like.
In addition, the heat dissipation device 100 may be connected to the power assembly 200 through the first pipeline 110, the coolant in the first pipeline 110 flows through the heat dissipation device 100, and the coolant in the first pipeline 110 is cooled by utilizing the heat exchange capability of the heat dissipation device 100, and then flows back to the power assembly 200 to take away the heat generated in the power assembly 200 to enter the next cooling cycle, as shown by the arrow in fig. 1. Thereby achieving cooling of the powertrain 200. Of course, the heat dissipation device 100 may also achieve the heat dissipation effect on the power assembly 200 through other implementations.
It should be noted that "the pump 500 is configured to drive the nozzle 300 to spray the cooling medium when the temperature of the heat dissipation apparatus 100 reaches the first set temperature value", here, a corresponding display and an alarm device may be provided to remind an in-vehicle person to manually operate the pump 500, and the pump 500 is started to drive the nozzle 300 to spray the cooling medium. Or the controller 900 can be connected with the pump 500 and the first temperature sensor 400 respectively, and the controller 900 can control the opening and closing of the pump 500, so as to realize automatic spraying and cooling.
In addition, if the cooling liquid/solid is used as the spray cooling medium in the present embodiment, the spray cooling medium may be water, or may be a substance such as liquid nitrogen or dry ice, and absorbs a large amount of heat by vaporization of the liquid/solid.
The cooling apparatus of the present embodiment may be used in a process that, first, the heat sink 100 performs normal cooling heat dissipation on the powertrain 200 of the vehicle in a case where the vehicle is in a normal heat dissipation requirement process, that is, in an environment of-15 ℃ to 41 ℃. When the first temperature sensor 400 detects that the temperature of the heat dissipation device 100 is higher than a first set temperature value (for example, higher than 41 ℃), the power assembly 200 cannot be effectively cooled due to the excessively high temperature of the heat dissipation device 100, at this time, the pump 500 drives the nozzle 300 to spray a cooling medium, and the sprayed cooling medium contacts the heat dissipation device 100 and takes away the heat of the heat dissipation device 100, so that the heat dissipation device 100 is cooled, and the heat dissipation device 100 is further ensured to still effectively cool the power assembly 200. Thereby solving the problem that the radiator of the existing special vehicle has poor radiating effect on the power assembly 200 of the vehicle. And only a small amount of mechanisms such as the nozzle 300, the pump 500, the first temperature sensor 400 and the like are added, so that the purpose of fully improving the cooling effect can be achieved, the cost of the cooling system is not increased greatly, and meanwhile, the occupied space is not large, so that excessive space in a power cabin of a vehicle is not occupied, and the arrangement of the whole vehicle is not influenced.
Preferably, the heat sink 100 includes a plurality of heat sinks, which are integrated.
By gathering a plurality of heat sinks together into an integrated structure, that is, integrating a plurality of heat sinks, all the heat sinks can be collectively sprayed and radiated by using the nozzle 300, so that the heat radiation effect of the heat radiation device 100 is improved, and the number of unnecessary nozzles 300 and pumps 500 is also reduced. Thereby further reducing the volume of the whole cooling device and facilitating the arrangement of the whole vehicle.
It should be noted that, here, "a plurality of radiators are gathered together to become an integrated structure", not only a plurality of radiators are connected in turn, but a plurality of radiators are compactly gathered to form an integrated structure with a small occupied space, such as a rectangular parallelepiped, so that the nozzles are convenient to intensively spray and cool.
Preferably, the radiator is a coolant radiator or a intercooler or a transmission oil radiator or a transfer case oil radiator.
Here, the coolant radiator, the intercooler, the transmission oil radiator and the transfer case oil radiator may be integrated to constitute the heat sink 100.
Through the above-mentioned many different radiators, effective heat dissipation to power assembly 200 is realized.
Referring to fig. 1, preferably, the heat sink 100 is connected to the powertrain 200 through a first pipe 110, and the first temperature sensor 400 is connected to the first pipe 110.
Here, the first pipe 110 may connect the input end of the heat sink 100 with the coolant output end of the powertrain 200, and the first pipe 110 may connect the output end of the heat sink 100 with the coolant input end of the powertrain 200, thereby forming a complete circulation pipe. The heat exchange capacity of the heat sink 100 is utilized to cool the coolant in the first pipeline 110, and then the coolant flows back into the power assembly 200 to take away the heat generated in the power assembly 200 and enter the next cooling cycle. Thereby achieving cooling of the powertrain 200.
In this way, the first temperature sensor 400 and the first pipeline 110 are used, so that the temperature of the heat sink 100 can be accurately detected by detecting the temperature of the cooling medium in the first pipeline 110, and the detection accuracy is ensured.
In particular, the first temperature sensor 400 is connected to the output end of the heat sink 100 of the first pipe 110, so that the temperature of the heat sink 100 can be sufficiently detected.

The fan 600 is an air suction fan, and can allow air to flow from the outside to the power assembly 200 through the heat dissipation device 100, so that the evaporation heat absorption effect of the sprayed cooling medium is accelerated, and the heat dissipation effect is improved. More importantly, the fan 600 is arranged between the heat sink 100 and the power assembly 200, rather than between the nozzle 300 and the heat sink 100, so that the fan 600 can avoid blocking the cooling medium sprayed by the nozzle 300, and the sprayed cooling medium can be sprayed on the surface of the heat sink 100 as much as possible, thereby ensuring the cooling effect.
Referring to fig. 1, preferably, the cooling apparatus further includes a second temperature sensor 700 for detecting a temperature of the vehicle; the pump 500 is also used for driving the spray nozzle 300 to spray the cooling medium when the temperature of the vehicle reaches a second set temperature value.
For a fire engine or other special vehicle, the temperature of the external environment in which the vehicle is located also directly affects the heat dissipation efficiency of powertrain 200. For example, for a fire engine, the temperature of the fire scene where the vehicle is located is high, which causes the temperature of the vehicle body to rise, and the temperature of the vehicle body rises, which eventually causes the temperatures of the power assembly 200 and the heat dissipation device 100 to rise, so that it is necessary to detect the temperature of the vehicle body to cool the heat dissipation device 100 in advance, thereby achieving the purpose of ensuring the cooling effect.
For this purpose, the temperature of the vehicle is detected by the second temperature sensor 700, and the pump 500 is further configured to drive the nozzle 300 to spray the cooling medium when the temperature of the vehicle reaches a second set temperature value, so as to cool the heat sink 100 in advance.
Of course, the second temperature sensor 700 and the first temperature sensor 400 do not conflict with each other here, the pump 500 may drive the spray nozzle 300 to spray the cooling medium when the temperature of the vehicle reaches the second set temperature value or the temperature of the heat sink 100 reaches the first set temperature value, and the second set temperature value may be less than or equal to the first set temperature value. Thereby ensuring safety of the driving of the pump 500.
Referring to fig. 1, preferably, the cooling apparatus further includes a valve 810 and a storage tank 820, and the nozzle 300, the pump 500, the valve 810 and the storage tank 820 are sequentially communicated through a second pipe 830.
The storage tank 820 stores the cooling medium sprayed from the spray nozzle 300, and the valve 810 controls the opening and closing of the entire second pipe 830, thereby ensuring safety.
Referring to fig. 1, preferably, the cooling apparatus further includes a controller 900, and the controller 900 is connected to the first temperature sensor 400, the second temperature sensor 700, the pump 500, and the valve 810, respectively.
Automatic spraying is achieved through the controller 900, and operation of personnel is reduced.
In addition, the embodiment also provides a vehicle comprising the cooling device.
Since the technical effect achieved by the vehicle is the same as that of the cooling apparatus, the technical effect of the vehicle will not be explained much.
Preferably, the vehicle is a fire engine.
In addition, the nozzle 300 of the cooling apparatus is disposed at a head front panel intake grill of the vehicle, and the heat sink 100 is disposed in the front panel intake grill. So set up, make whole automobile body rational in infrastructure.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Without departing from the spirit and scope of the present disclosure, those skilled in the art can make various changes and modifications, which will fall into the scope of the present disclosure.
