Referring to fig. 1 and 2, the present invention provides an embodiment of an electrical control box 200, which is suitable for being installed in an electrical apparatus as an electrical control device. For example, the electrical control box 200 may be applied to an air conditioner or other home appliances. The air conditioner may be a window type air conditioner 100 or a split type air conditioner. In the case of the window type air conditioner 100, the electrical control box 200 may be installed in an indoor side housing of the window type air conditioner 100, or may be installed in an outdoor side housing of the window type air conditioner 100. For the split type air conditioner, the electrical control box 200 can be installed in both indoor and outdoor units. In the following embodiments, the electric control box 200 is mainly applied to the window type air conditioner 100 as an example.

Referring to fig. 3 to 5, in an embodiment of the electrical control box of the present invention, the electrical control box 200 includes a box body 210 and an electrical control board 220. The box body 210 comprises a bottom plate 211 and a box cover 212 which is matched and covered with the bottom plate 211, the bottom plate 211 comprises an outer metal bottom plate 300 and an inner plastic bottom plate 400, and the electric control plate 220 is installed on the inner plastic bottom plate 400. The inner plastic base plate 400 is hollowed out at a position corresponding to the electric control plate 220, so that a heat dissipation area 250 is formed between the electric control plate 220 and the outer metal base plate 300.

Specifically, the cover 212 of the box body 210 also includes an outer metal cover 500 and an inner plastic cover 600. That is, the case body 210 of the electrical control case 200 actually has an inner layer portion and an outer layer portion; wherein, the inner layer part consists of an inner layer plastic bottom plate 400 and an inner layer plastic box cover 600; the inner layer part is made of plastic materials, so that the manufacturing and forming are convenient, and the manufacturing cost is low. The outer layer part consists of the outer layer metal bottom plate 300 and the outer layer metal box cover 500; this outer part adopts the sheet metal component to make, can play the rust-resistant effect of fire prevention for automatically controlled box 200 has higher security performance. When assembling the electrical control box 200, the electrical control board 220 is first mounted on the bottom board 211; then, the cover 212 is closed to the bottom plate 211.

Due to the difference in material properties, the heat transfer efficiency of the outer metal baseplate 300 is greater than that of the inner plastic baseplate 400. If the position of the inner plastic base plate 400 corresponding to the electric control plate 220 is not hollow, the heat generated by the electric control box 200 needs to be transferred to the inner plastic base plate 400 first, and then transferred to the outer metal base plate 300 through the inner plastic base plate 400, which results in poor heat dissipation efficiency.

The technical scheme of the utility model, through corresponding of inlayer plastic bottom plate 400 the position of automatically controlled board 220 is the fretwork setting, makes automatically controlled board 220 with be formed with radiating area 250 between the outer metal bottom plate 300 to automatically controlled board 220 directly radiates the heat through this radiating area 250 outside outer metal bottom plate 300, and the final outer metal bottom plate 300 of process radiates away. In addition, the heat dissipation area 250 is provided, that is, a distance is provided between the electric control board 220 and the outer metal base plate 300, and the distance can prevent the electric control board 220 from contacting the outer metal base plate 300, so that the electric control board 220 can avoid the occurrence of an electric leakage accident through the outer metal base plate 300, and the safety performance of the electric control box 200 can be improved.

Referring to fig. 3 to 5, since the heat dissipation region 250 is formed between the electric control board 220 and the outer metal base plate 300, the electric control board 220 and the outer metal base plate 300 are disposed at an interval. As shown in D of FIG. 5₁Indicated as the spacing between the electrical control board 220 and the outer metal chassis 300. Theoretically, D₁The larger the size, the more favorable the airflow can pass to achieve quick heat dissipation; however, the space inside the electrical control box 200 is also occupied, so that the overall volume of the electrical control box 200 is increased. Thus, D₁Should be kept within a certain range.

The research shows that when the electric control board 220 is connected with the outsideThe spacing between the metal bottom plates 300 is not less than 8mm and not more than 18mm (i.e. D is not less than 8mm)₁Less than or equal to 18mm), a larger gap can be obtained between the electric control board 220 and the outer layer metal base plate 300, and the electric control box has better heat dissipation efficiency and safety performance, and occupies a smaller space of the electric control box 200, so that the whole volume of the electric control box 200 can still be kept smaller. Therefore, the spacing between the electronic control board 220 and the outer metal base plate 300 may be selected to be not less than 8mm, and not more than 18 mm. Such as but not limited to: 8mm, 10mm, 12mm, 15mm, 16mm, 17mm, and the like. The electronic control board 220 may be designed accordingly according to the size thereof, and is not particularly limited herein.

Further, the distance between the electric control board 220 and the outer metal bottom board 300 can also be selected to be not less than 10mm and not more than 15 mm. Within this range, the efficiency of the electronic control board 220 radiating heat to the outer layer metal base plate 300 is better; moreover, the difficulty of constructing and forming the heat dissipation region 250 between the inner plastic base plate 400 and the outer metal base plate 300 is low, and the manufacturing and molding are convenient. As for the specific values of the distance, there may be, but not limited to: 10mm, 11mm, 12mm, 13mm, 14mm, and the like.

Referring to fig. 6 to 8, in an embodiment, the inner plastic base 400 is configured with a grid bracket 420 at a hollow position 410, and the grid bracket 420 separates the electric control board 220 from the outer metal base 300. The grill support 420 is integrally formed with the inner plastic chassis 400. The grill support 420 includes a plurality of grill bars arranged in a crisscross pattern. The grid support 420 can increase the strength of the hollow-out position 410 of the inner plastic base plate 400, so that the inner plastic base plate 400 can strongly support electric control components such as the electric control board 220.

In addition, when the electronic control box 200 is used for a period of time or an external component is pressed to the outer metal base plate 300, the outer metal base plate 300 may be deformed concavely toward the heat dissipation region 250, and if the deformed position of the outer metal base plate 300 contacts the electronic control board 220, the electronic control board 220 may leak electricity through the outer metal base plate 300, which may cause a safety hazard. After the grid support 420 is formed at the hollow position 410 of the inner plastic base plate 400, even if the outer metal base plate 300 is deformed toward the heat dissipation area 250, the deformed position of the outer metal base plate 300 is blocked by the grid support 420, so that the electric control board 220 is difficult to contact, and the occurrence of potential safety hazards is reduced.

Referring to fig. 5, 6 and 7, in an embodiment, the grid bracket 420 and the electronic control board 220 are spaced apart from each other, and the heat dissipation area 250 includes an inner heat dissipation area 251 formed between the grid bracket 420 and the electronic control board 220. That is, the back surface of the electric control board 220 is not in contact with the grill bracket 420, so that the shielding of the grill bracket 420 on the back surface of the electric control board 220 can be reduced, and a larger heat dissipation surface is formed on the back surface of the electric control board 220. The heat generated by the electronic control board 220 is conducted to the outer metal base plate 300 through the inner heat dissipation area 251, and then dissipated through the outer metal base plate 300.

Further, a plurality of supporting members 430 are protruded around the hollow positions 410 of the inner plastic base plate 400, and the plurality of supporting members 430 support the electronic control board 220 in a matching manner, so that the inner heat dissipation area 251 is formed between the grid support 420 and the electronic control board 220. The plurality of supporting members 430 are protrusions formed on the surface of the inner plastic soleplate 400. The supporting members 430 are arranged at intervals around the hollow positions 410 of the inner plastic base plate 400.

Referring to fig. 5, 6 and 7, in an embodiment, the grid support 420 and the outer metal base plate 300 are disposed at an interval; the heat dissipation region 250 includes an outer heat dissipation region 252 formed between the grill support 420 and the outer metal base plate 300. That is, the grill support 420 is not in contact with the outer metal bottom plate 300. The heat generated by the electronic control board 220 is conducted to the outer metal base plate 300 through the inner heat dissipation area 251 and the outer heat dissipation area 252, and then dissipated through the outer metal base plate 300. The existence of the outer heat dissipation region 252 increases the safety distance between the electronic control board 220 and the outer metal base plate 300, which can greatly improve the safety performance of the electronic control box 200.

Further, the outer layer metal base plate 300 is recessed from the inside to the outside at a position corresponding to the electric control board 220 to form a groove 510 at the recessed position, and the outer layer metal base plate 300 forms the outer layer heat dissipation area 252 between the bottom surface of the groove 510 and the grill bracket 420. Because the outer layer metal base plate 300 has a smaller thickness and better ductility, the outer layer heat dissipation region 252 is formed by recessing the outer layer metal base plate 300 from inside to outside, which is easier to manufacture and more efficient. Moreover, the groove 510 is formed on the outer metal base plate 300, so that the strength of the outer metal base plate 300 can be enhanced, the outer metal base plate 300 is not easy to deform toward the electronic control board 220, the outer metal base plate 300 is prevented from directly contacting the electronic control board 220, and the safety performance of the electronic control box 200 is improved.

Referring to fig. 6, 7 and 9, according to any of the above embodiments, a main cavity 601 is configured inside the inner plastic box cover 600, and the main cavity 601 is suitable for accommodating components on the power supply control board 220. Considering that the main heat source of the electrical control box 200 comes from the electrical control board 220, the heat transfer efficiency of the inner plastic box cover 600 is low, which is not favorable for heat dissipation. Therefore, a plurality of heat dissipation holes 610 may be formed through the inner plastic cover 600 on the sidewall corresponding to the main cavity 601.

Specifically, the plurality of heat dissipation holes 610 are arranged at intervals in the vertical direction. The heat in the main cavity 601 can be dissipated to the gap between the inner plastic box cover 600 and the outer metal box cover 500 through the plurality of heat dissipating holes 610, and then dissipated to the outside through the outer metal box cover 500.

It is considered that moisture in the external environment may penetrate into the interior through a gap (e.g., a gap between the outer metal bottom plate 300 and the outer metal lid 500, or a gap at a connecting position of the electronic control box 200 and the housing of the product to which the electronic control box is applied) on the box body 210, and then enter the main cavity 601 through the heat dissipation hole 610, so that the electronic control board 220 may be affected by moisture and fail.

In order to avoid this, a water retaining fence 620 may be protruded at the periphery of the heat dissipation hole 610, the water retaining fence 620 surrounds the heat dissipation hole 610, and the water retaining fence 620 is inclined from the inner side of the heat dissipation hole 610 to the outer side thereof. Therefore, when on the lateral wall of the main cavity 601 in the external environment, being sheltered from and guided by the water baffle 620 and dropping downwards in turn, and then flowing to the bottom of the box body 210, discharging to the chassis 110 from the gap at the bottom of the box body 210, thereby avoiding water drops entering the main cavity 601 from the heat dissipation hole 610, and reducing the occurrence of the fault caused by the damp of the electric control board 220.

In one embodiment, the electrical control box 200 further comprises a reactor 230, wherein the reactor 230 is fixed on the outer metal base plate 300 through the inner plastic base plate 400; the inner plastic cover 600 is configured with a secondary cavity 602, and the secondary cavity 602 is suitable for accommodating the reactor 230.

The outer metal base plate 300 is made of a sheet metal part, so that the outer metal base plate 300 has higher strength and is not easy to bend and deform compared with the inner plastic base plate 400. Therefore, the reactor 230 is fixed to the outer-layer metal base plate 300 so that the reactor 230 can be strongly supported by the outer-layer metal base plate 300, and the outer-layer metal base plate 300 is less likely to be deformed. The electronic control box 200 further includes a heat sink 240, and the heat sink 240 is mounted on one end of the electronic control board 220 and extends outward from the box cover 212.
