The preferred embodiments of the utility model are described in detail as follows, however, in addition to these detailed descriptions, the utility model can have other implementation manners.

[0027] Referring to Figures 1-5 The utility model provides a kind of PCS electric energy manager heat dissipation structure, and PCS electric energy manager heat dissipation structure includes shell 1, and the side of shell 1 is the heat dissipation side plate 13 with certain thickness.

[0028] As shown in Figures 3-4 Heat dissipation side plate 13 evenly distribute several V-shaped air outlets 5 for heat dissipation, and V-shaped air outlet 5 one end is provided with a pair of outer heat dissipation holes 14 formed in upper and lower distribution on outer side wall, and V-shaped air outlet 5 other end is provided with an inner heat dissipation hole 15 on inner side wall.

[0030] A cover plate 3 is vertically rotatably installed on one side of the outer shell 1 and the sealing cover 9 close to the heat dissipation side plate 13, the upper part of the cover plate 3 extends into the sealing cover 9 through the air vent 11 and faces the air outlet side of the fan 2, and the lower part of the cover plate 3 close to one side of the V-shaped air outlet 5 is uniformly distributed with a plurality of flow guide covers 6 which are insertedly connected with the inner heat dissipation holes 15, the flow guide covers 6 are bullet-shaped and have pointed ends, the bottom of the end of each flow guide cover 6 is provided with a gas guide hole 19, and the cover plate 3 is provided with a plurality of through holes 18 which are respectively arranged in the flow guide covers 6.

[0031] The cover plate 3 is in a vertical state when it is not subjected to force, at this time, each flow guide cover 6 of the cover plate 3 is inserted into the inner heat dissipation hole 15 (as shown in Figure 4 ), and the outer part of the flow guide cover 6 contacts with the upper edge of the inner side of the inner heat dissipation hole 15, which has a certain sealing effect and can prevent external dust and rain from entering the inside of the outer shell. It should be noted that the flow guide cover 6 is inserted into the inner heat dissipation hole 15 along with the vertical rotation of the cover plate 3, that is, the flow guide cover 6 is also rotated and inserted into the inner heat dissipation hole 15, in order to ensure that the flow guide cover 6 can be smoothly inserted into the inner heat dissipation hole 15, the height of the inner heat dissipation hole 15 needs to be greater than the height of the flow guide cover 6, and after the flow guide cover 6 is inserted into the inner heat dissipation hole 15, the upper end surface of the flow guide cover 6 is in good contact with the inner wall of the inner heat dissipation hole 15, which has a certain waterproof effect; and the lower end surface of the flow guide cover 6 needs to be kept a certain distance from the inner wall of the inner heat dissipation hole 15, so as to ensure that the cover plate 3 can drive the flow guide cover 6 to be smoothly inserted into the inner heat dissipation hole 15.

[0032] When heat dissipation is needed, the fan 2 blows air to the cover plate 3 to make the cover plate 3 rotate away from the V-shaped air outlet 5, at the same time, the flow guide cover 6 also moves away from the inner heat dissipation hole 15 to open the inner heat dissipation hole 15 and connect the inside of the outer shell 1 with the outside, which helps heat dissipation; at the same time, a gap is formed between the cover plate 3 and the inner side wall of the heat dissipation side plate 13, which facilitates the rapid and smooth exhaust of hot air in the inside of the outer shell 1.

[0033] In an optional embodiment, the cover plate 3 is provided with a horizontal rotating shaft 12 which is arranged in the sealing cover 9, the horizontal rotating shaft 12 is arranged on the side of the cover plate 3 which is away from the fan 2, and a counterweight is arranged at the bottom of the cover plate 3, so as to keep the cover plate 3 in a vertical state when it is not subjected to force, thereby ensuring sealing.

[0034] In an optional embodiment, a wind cover 4 is fixed to the cover plate 3 in the sealing cover 9 and faces the air outlet hole of the fan 2 (as shown in Figure 3 ), the wind cover 4 faces the air outlet side of the fan 2, which can effectively gather the air blown by the fan 2 and better push the cover plate 3 to rotate vertically. In addition, the bottom of the wind cover 4 is also provided with a flow guide groove 16 (as shown inFigure 5 As shown), and the guide groove 16 is connected to the vent 11, which can guide the air gathered by the hood to the inside of the outer casing 1 through the vent 11 (as shown). Figure 3 (As shown by the dotted line), it serves to dissipate heat. Hot air inside the outer casing 1 passes through the through hole 18, the air guide hole 19, and the V-shaped air outlet 5 (as shown by the dotted line). Figure 4 (Arrow) and the gap between cover plate 3 and heat dissipation side plate 13 blow out of the equipment.

[0035] Since the fan 2 needs to remain continuously operating to ensure that the cover plate 3 is in an inclined state, this application provides a transverse electric actuator 17 in the sealing cover 9 to assist in rotating the cover plate 3. Compared with the wind-driven method, the transverse electric actuator 17 can remain in its current position after extending, thereby keeping the cover plate 3 in a constantly inclined posture to ensure heat dissipation. After the transverse electric actuator 17 retracts, it does not contact the cover plate 3, allowing the cover plate 3 to automatically return to its vertical position.

[0036] In an optional embodiment, the cover plate 3 is densely covered with a number of perforated holes 7 located between the air guide shrouds 6, which helps to reduce the weight of the cover plate 3 on the one hand, and accelerates heat dissipation when the air guide shrouds 6 are separated from the V-shaped air outlets 5 on the other hand.

[0037] A temperature controller is installed inside the outer casing 1 to control the fan 2 and / or the horizontal electric actuator 17 according to the internal temperature. When the temperature is high, the cover plate 3 tilts to assist in heat dissipation. After the temperature returns to normal, the fan 2 and / or the horizontal electric actuator 17 are controlled to return the cover plate 3 to its original position and vertical state to ensure a seal.
