Referring to fig. 1-3, the insulation system disclosed in the embodiments of the present application includes a heat generating component, a liquid container 400, a heat exchanger 300, and an infusion line 500. The heat generating component is not a heating device, but can generate heat in the normal working process, and the temperature of the heat generating component is increased, such as components of the engine 100, the compressor and the like; the liquid container 400 is used for containing liquid, and the liquid in the liquid container 400 is used as a cold source to exchange heat with a heat source in the heat exchanger 300. Herein, the liquid container 400 is a water source of a waterway of the vehicle.

The heat generating component is provided with a first heat source channel 110, and the first heat source channel 110 is used for supplying heat source circulation so that heat generated by the heat generating component in the working process can be transferred to the heat source. Thus, the heat absorption temperature of the heat source is increased, and meanwhile, the temperature of the heat generating component is reduced, so that the heat generating component is prevented from being excessively high.

The heat exchanger 300 is provided with a second heat source passage 310, an inlet end of the first heat source passage 110 is communicated with an outlet end of the second heat source passage 310, and an outlet end of the first heat source passage 110 is communicated with an inlet end of the second heat source passage 310, so that the heat source circulates between the first heat source passage 110 and the second heat source passage 310. Specifically, as shown in fig. 1, the inlet end of the first heat source channel 110 and the outlet end of the second heat source channel 310 may be connected by a first pipe, one end of the first pipe is connected to the inlet end of the first heat source channel 110, and the other end of the first pipe may be connected to the outlet end of the second heat source channel 310; likewise, the outlet end of the first heat source channel 110 and the inlet end of the second heat source channel 310 may be connected through a second pipe, one end of which is connected to the outlet end of the first heat source channel 110, and the other end of which may be connected to the inlet end of the second heat source channel 310.

The heat exchanger 300 is further provided with a cold source channel 320, and an inlet end of the cold source channel 320 is communicated with the liquid container 400, so that liquid in the liquid container 400 can enter the cold source channel 320, and the liquid flowing through the cold source channel 320 can exchange heat with a heat source in the second heat source channel 310. Therefore, the heat source can continuously absorb the heat generated by the heat generating component and exchange heat with the liquid, and finally, the heat of the heat generating component is transferred to the liquid, so that the temperature of the liquid is increased.

Specifically, the liquid container 400 may be a clean water tank for containing clean water, and of course, the liquid container 400 may also be a container for containing other liquids. The inlet end of the cold source channel 320 may be connected to the outlet end of the liquid container 400 through a third pipe, one end of which is connected to the outlet end of the liquid container 400, and the other end of which may be connected to the inlet end of the cold source channel 320.

Moreover, the outlet end of the cold source channel 320 is communicated with the infusion line 500, so that the liquid (that is, the water in the waterway) with which the heat exchange in the cold source channel 320 is completed flows through the infusion line 500, and the infusion line 500 is heated, thereby avoiding the temperature of the infusion line 500 from being too low. Specifically, the end of the infusion line 500 may be directly connected to the outlet end of the cold source channel 320, or may be connected to the outlet end of the cold source channel 320 through a fourth line, one end of the fourth line is connected to the end of the infusion line 500, and the other end of the fourth line may be connected to the outlet end of the cold source channel 320.

So arranged, because the liquid flows through the whole infusion pipeline 500, the heat of the liquid has a heat preservation heating effect on the whole infusion pipeline 500, and the heat preservation heating area is large; and moreover, the heat generated naturally in the working process of the heat generating component is utilized, and heating devices such as a warm air blower, an incubator and the like are not required to be specially added to generate the heat, so that the use cost is low.

In an alternative embodiment, the heat generating component includes engine 100, first heat source passage 110 includes an antifreeze fluid passage, and the heat source includes antifreeze fluid. Wherein, the antifreeze fluid passage is provided in the engine 100, and the antifreeze fluid passage is used for circulation of antifreeze fluid. Specifically, the antifreeze fluid passage may be formed by a pipe wound around the outer surface of the engine 100, and the material of the pipe is a heat conductive material, and the heat of the engine 100 is transferred to the pipe and then transferred to the antifreeze fluid in the pipe.

The inlet end of the antifreeze fluid passage and the outlet end of the second heat source passage 310 may be communicated through a first pipe, and the outlet end of the antifreeze fluid passage and the inlet end of the second heat source passage 310 may be communicated through a second pipe, thereby circulating antifreeze fluid between the antifreeze fluid passage and the second heat source passage 310.

So arranged, heat generated in the working process of the engine 100 can be transferred to the antifreeze, and the antifreeze flows through the second heat source channel 310, so that heat exchange is performed between the antifreeze and the liquid in the cold source channel 320, the temperature of the antifreeze is reduced, and the temperature of the antifreeze is prevented from being too high; at the same time, the temperature of the liquid increases, and the liquid heats the infusion line 500. Further, since the antifreeze circulates between the antifreeze passage and the second heat source passage 310, the antifreeze can continuously absorb the heat of the engine 100 and continuously exchange heat with the liquid.

In an alternative embodiment, the heat generating component includes hydraulic system 200, the first heat source passage 110 includes a hydraulic oil passage, and the heat source includes hydraulic oil. The hydraulic oil channel is disposed in the hydraulic system 200, and is used for hydraulic oil circulation. Specifically, the hydraulic oil passage is provided inside the hydraulic system 200, and the continuous compression process of the hydraulic system 200 may cause overheating of the hydraulic oil inside thereof, i.e., heat generated by mechanical friction is transferred to the hydraulic oil.

Further, since the hydraulic oil circulates between the hydraulic oil passage and the second heat source passage 310, the hydraulic oil can continuously absorb heat and continuously exchange heat with the liquid.

Alternatively, the number of the first heat source channels 110 and the second heat source channels 310 is at least two, and corresponds one to one. In the present embodiment, the number of the second heat source channels 310 and the number of the cold source channels 320 in the heat exchanger 300 are both one, so the number of the heat exchangers 300 is at least two. Of course, in other embodiments, at least two second heat source channels 310 and at least two heat sink channels 320 may be provided within the same heat exchanger 300.

As shown in fig. 3, the number of the first heat source channels 110 and the number of the second heat source channels 310 are two, the two first heat source channels 110 are an antifreeze fluid channel and a hydraulic oil channel respectively, and the two second heat source channels 310 are communicated with the antifreeze fluid channel and the hydraulic oil channel respectively.

Specifically, in the case that the temperature detected by the temperature detecting element 620 is lower than the preset temperature, it means that the temperature of the heat source is too low to exchange heat with the liquid, the liquid cannot absorb heat, and even if the liquid flows through the infusion line 500, the liquid cannot be heated and kept warm, so the control element 630 controls the executing element to disconnect the cold source channel 320, and the liquid cannot flow through the cold source channel 320 and cannot enter the infusion line 500; in the case that the temperature detected by the temperature detecting element 620 is higher than the preset temperature, the temperature of the heat source is too high, and heat exchange with the liquid is required, and the control element 630 controls the actuator to conduct the cold source channel 320.
