For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0041] Energy storage battery containers and energy storage battery cabinets are generally placed in areas with unpredictable climates, such as open outdoors, far away from city centers. Especially in areas with frequent sandstorms, the harsh climatic conditions seriously affect the cooling effect and service life of air conditioners.

[0042] At present, thermal management units on the market, such as air-conditioning units, generally use outer cover filters to deal with the above weather conditions. However, this solution has the following shortcomings: first, it affects the appearance; second, it needs to be replaced regularly, which is inconvenient to operate. In addition, due to site restrictions, energy storage devices such as energy storage containers and energy storage battery cabinets are often placed densely, which may cause the air conditioners hung between two adjacent rows of energy storage devices to be arranged side by side or opposite to each other, causing the air conditioners to blow and affect each other, thereby causing a short circuit in the wind field and affecting the operation of the air-conditioning unit.

[0043] Reference Figures 1 to 3 As shown, the embodiment of the present application discloses a thermal management unit, which includes a main body 200 and an air guide device 100, and the main body 200 includes a shell 201, a partition 202, a compressor 203, a condenser 204, an evaporator 205, an external fan 206, an internal fan 207, an electric heater 209 and an electric control box 208. The partition 202 is arranged in the shell 201 and connected to the inner wall of the shell 201 to separate the shell 201 into a first cavity and a second cavity. The shell 201 is provided with a first air outlet 201a and a second air outlet (not shown in the figure), the first air outlet 201a is located in the first cavity, and the second air outlet is located in the second cavity. The compressor 203, the condenser 204 and the external fan 206 are respectively installed in the first cavity, the evaporator 205 and the internal fan 207 are respectively installed in the second cavity, and the compressor 203, the condenser 204 and the evaporator 205 are connected in sequence. The electric control box 208 is connected to the compressor 203, the external fan 206 and the internal fan 207 respectively, and is used to control the operation of the compressor 203, the external fan 206 and the internal fan 207. The air guide device 100 is mounted at the first air outlet 201a of the housing 201, and is used to guide the air discharged from the thermal management unit to a first direction, and the first direction intersects with the horizontal direction. In this embodiment, the air guide device 100 is used to guide the air discharged from the thermal management unit to the top of the thermal management unit.

[0044] During cooling, the refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant by the compressor 203 and then enters the condenser 204. The gaseous refrigerant undergoes heat exchange in the condenser 204 to become a liquid refrigerant, and then is input into the evaporator 205 through the throttling element. The refrigerant undergoes heat exchange in the evaporator 205 to become a gaseous refrigerant and then enters the compressor 203. The indoor fan 207 is used to transport the air with a lower temperature after heat exchange with the evaporator 205 to the room through the second air outlet, and the outdoor fan 206 is used to transport the air with a higher temperature after heat exchange with the condenser 204 to the outside through the first air outlet 201a.

[0045] Reference Figure 4 and Figure 5As shown, the wind guide device 100 includes a wind guide plate 101 and a wind guide structure 102 arranged on the wind guide plate 101.

The wind guide structure 102 includes a louver 102b and a wind guide hole 102a, the wind guide hole 102a is opened on the wind guide plate 101, the louver 102b is connected to the wind guide plate 101 and is located on the outside of the wind guide plate 101, and the louver 102b is located at the wind guide hole 102a, so that the wind discharged from the first air outlet 201a can be guided to the first direction through the cooperation of the louver 102b and the wind guide hole 102a. In this embodiment, the outer surface of the wind guide plate 101 is arranged flush with the outer surface of the shell 201, so that the shape of the thermal management unit itself can be maintained, the volume is small, and the wind resistance is smaller.

[0046] Specifically, the position of the first air outlet 201a is set corresponding to the position of the condenser 204, and a guide channel 300 is provided between the air guide plate 101 and the condenser 204, and a discharge port 302 is provided at the lower part of the air guide plate 101, and the discharge port 302 is connected to the guide channel 300. The height of the bottom wall of the guide channel 300 close to the discharge port 302 is lower than the height of the end away from the discharge port 302. Through the setting of the guide channel 300 and the discharge port 302, the present embodiment can effectively guide the sand, dust, rainwater, etc. entering the main body 200 to flow to the discharge port 302 through the guide channel 300, and discharge from the discharge port 302, thereby preventing rainwater from accumulating at the bottom of the air guide device and overflowing into the interior of the thermal management unit, and also preventing wind and sand particles from accumulating at the bottom of the air guide device and causing the unit to be dirty and blocked. At the same time, the bottom wall of the guide channel 300 is set to have a lower height at the end close to the discharge port 302 than at the end away from the discharge port 302, thereby facilitating the smooth discharge of rainwater and dust and avoiding accumulation at the bottom that blocks the discharge port.

[0047] In this embodiment, the opening of the louver 102b is set upward, and the angle between the louver 102b and the air guide plate 101 is α, and the angle α is an acute angle. For example, the angle α can be 30°, 45°, 60°, etc. In this embodiment, the air inlet of the first cavity is located below the first air outlet. In order to prevent the hot air discharged from the first air outlet from being sucked into the first cavity from the air inlet by the external fan and affecting the condensation, the louver is set upward. In other embodiments, it can also be facing other directions.

[0048] In order to prevent dust and impurities from entering the main body 200 and affecting the normal operation of various components in the main body 200, the main body 200 also includes a filter plate 301. At least a portion of the filter plate 301 is arranged between the air guide plate 101 and the condenser 204.

It has a closed connection structure to prevent dust and impurities from entering the main body 200 through the filter plate 301.

[0049] The thermal management unit of this embodiment is provided with two protective barriers. The air guide device 100 can serve as the first external air barrier, and the filter plate 301 can serve as the second barrier. The two barriers can simultaneously resist dust and sand and have a filtering effect, which is helpful to extend the service life of the thermal management unit.

[0050] Without changing the external dimensions of the thermal management unit, the present application specially designs the air guide device to change the air outlet direction of the thermal management unit, so that the hot air blown out by the thermal management unit is directed to the upper or obliquely upper part of the thermal management unit with better air flow, so as to avoid the air outlets of two energy storage devices blowing against each other when the energy storage devices are densely placed, thereby affecting the heat dissipation effect, and at the same time avoid the hot air blown out from the horizontal direction from being re-inhaled into the air inlet of the thermal management unit, causing a short circuit in the wind field, thereby affecting the cooling effect of the thermal management unit. At the same time, the air guide device can also form an air barrier on the outside of the thermal management unit, acting as a dust and sand filter, thereby extending the life of the thermal management unit.
