[0036] Reference below Figure 1-Figure 8 The electric control box 100 according to the embodiment of the present invention is described. The baffle 14 is installed in the electric control box 100 to shield the electric control board, thereby preventing the electric control board from being damaged by water ingress, and heat is dissipated through the heat dissipation duct 131 between the baffle 14 and the heat dissipation side wall 12, so as to effectively avoid fire. It should be noted that the electric control box 100 in the present invention can be applied to electrical equipment to ensure the safety and reliability of the electrical equipment, wherein the electrical equipment can be an air conditioner, and the electric control box 100 can be installed on the outdoor unit of the air conditioner.

[0037] like Figure 1-Figure 2 As shown, an electric control box 100 according to an embodiment of the present invention includes: a box body 11 , a heating component 13 and a baffle 14 .

[0038] An installation cavity 111 is formed in the box body 11, and the heating component 13 is installed in the installation cavity 111. The box body 11 can be constructed as a box-shaped structure with an open top, so that the heating component 13 can be installed from the top of the box body 11, and an electric control box cover 112 is provided on the upper part of the box body 11, and the electric control box cover 112 can close the top of the installation cavity 111. That is, the installation cavity 111 is used to provide an installation space for the heating component 13 inside the electric control box 100, and the heating component 13 can be an electric control board and other electronic components.

[0039] The box body 11 has a heat dissipation side wall 12, and a heat dissipation hole 121 is provided on the heat dissipation side wall 12. The heat dissipation hole 121 is communicated with the installation cavity 111, so that the airflow in the installation cavity 111 can exchange heat with the outside of the electric control box 100 through the heat dissipation hole 121 on the heat dissipation side wall 12, thereby, the heat generated in the installation cavity 111 can be discharged to the outside of the electric control box 100 through the heat dissipation hole 121. Specifically, the heat dissipation side wall 12 can be the rear side wall of the box body 11, or the left side wall, the right side wall, etc., which can be used to achieve internal heat dissipation.

[0040] In other words, after the heat-generating components 13 such as the electric control board are installed in the installation cavity 111, when the electrical equipment is working, the heat-generating components 13 operate in the installation cavity 111 and generate heat. The generated heat can diffuse toward the outside of the electric control box 100 through the heat dissipation holes 121 of the heat dissipation side wall 12 to achieve heat discharge, so that the heat-generating components 13 can be maintained in a safe temperature state, avoiding overheating of the heat-generating components 13 and ensuring the safety of the operation of the electrical equipment.

[0041] The baffle 14 is installed in the installation cavity 111, and at least part of the baffle 14 is located between the heat dissipation hole 121 and the heat-generating component 13. A heat dissipation duct 131 communicating with the heat dissipation hole 121 is defined between the baffle 14 and the heat dissipation side wall 12. It can be understood that the baffle 14 is installed in the installation cavity 111, and at least part of the baffle 14 is located between the heat dissipation hole 121 and the heat-generating component 13. The baffle 14 separates the heat-generating component 13 from the heat dissipation hole 121, and shields the heat-generating component 13, thereby preventing rainwater from entering the box body 11 from the heat dissipation hole 121 and directly acting on the heat-generating component 13, causing the heat-generating component 13 to become water-infiltrated and fail.

[0042] Furthermore, the baffle 14 and the heat dissipation side wall 12 define a heat dissipation duct 131, and the heat emitted from the heat generating component 13 to the installation cavity 111 will enter the heat dissipation duct 131 and then be discharged through the heat dissipation hole 121. When there is an open flame outside the electric control box 100, the baffle 14 can also shield the open flame, that is, it can prevent the open flame from entering the installation cavity 111 from the heat dissipation hole 121 to act on the heat generating component 13, thereby, the heat in the installation cavity 111 can be well guided from the heat dissipation duct 131 to the heat dissipation hole 121 and discharged outwardly, and the external open flame will not directly enter the installation cavity 111 from the heat dissipation duct 131 to directly act on the heat generating component 13 under the action of the baffle 14, thereby, the baffle 14 can play a role of fireproof and waterproof.

[0043] It should be noted that the heating component 13 can be electrically connected to the structure outside the electric control box 100 through the copper tube to achieve control of the external structure. A copper tube support structure 150 can be set in the electric control box 100. The copper tube support structure 150 forms a supporting surface in the installation cavity 111 for supporting the copper tube to ensure the stability of the copper tube. At the same time, it can increase the strength of the electric control box 100 to make it less likely to deform.

[0044] Therefore, by installing the baffle 14 inside the box body 11, the shielding effect of the baffle 14 can effectively prevent rainwater and open flames from entering the electric control box 100, and the heat dissipation duct 131 formed by the baffle 14 and the heat dissipation side wall 12 can ensure the heat dissipation effect, thereby preventing the electric control box 100 from catching fire due to excessive heat inside.

[0045] According to the electric control box 100 of the embodiment of the present invention, the heat generating component 13 is arranged in the installation cavity 111, and the heat dissipation hole 121 of the heat dissipation side wall 12 is used for heat dissipation. A baffle 14 is arranged in the installation cavity 111 to play a shielding role to prevent rainwater from entering the box body 11 through the heat dissipation hole 121 and causing the electric control board to fail due to water ingress. A heat dissipation duct 131 is formed between the baffle 14 and the heat dissipation side wall 12 to ensure the heat dissipation effect and avoid fire caused by excessive internal temperature.

[0046] In some embodiments, the baffle 14 includes a shielding portion 141 and a connecting portion 142, wherein the shielding portion 141 shields between the heat dissipation hole 121 and the heat generating component 13, and the connecting portion 142 is bent and connected to the shielding portion 141, and the connecting portion 142 is connected to the box body 11. Figure 3 As shown, the shielding portion 141 separates the heat dissipation holes 121 from the heat generating components 13, thereby preventing rainwater from entering the box body 11 through the heat dissipation holes 121 and directly acting on the heat generating components 13, causing the heat generating components 13 to become ineffective due to water ingress. Meanwhile, the shielding portion 141 can also prevent open flames outside the box body 11 from entering the box body 11 through the heat dissipation holes 121 and directly acting on the heat generating components 13, thereby achieving waterproof and fireproof effects.

[0047] At the same time, the connecting portion 142 is suitable for installing the baffle 14 inside the box body 11, that is, the baffle 14 is connected to the box body 11 through the connecting portion 142. The connection method can be bolt connection, or the two can be connected by other connecting parts. The structure is simple and easy to install.

[0048] Among them, the connecting portion 142 is bent and connected to the shielding portion 141, so that the connecting portion 142 and the shielding portion 141 can extend in different directions respectively. Therefore, when the shielding portion 141 is opposite to the heat dissipation side wall 12 to block and shield the fluid at the heat dissipation hole 121, the connecting portion 142 can be bent to connect with other side walls of the box body 11, such as the connecting portion 142 can be connected to the top wall of the box body 11, or to the bottom wall of the box body 11, or to other side walls adjacent to the heat dissipation side wall 12, so that the baffle 14 and the heat dissipation side wall 12 are better spaced apart to form an effective heat dissipation duct 131.

[0049] Furthermore, the connecting portion 142 and the shielding portion 141 may be constructed as one body to enhance structural strength.

[0050] In some embodiments, the connecting portion 142 is bent and connected to the lower side of the shielding portion 141, and the connecting portion 142 is connected to the bottom wall of the box body 11. Figure 6 As shown, the connection between the connecting portion 142 and the shielding portion 141 is located at the lower side of the shielding portion 141, and the connecting portion 142 is arranged horizontally in the front-to-back direction, so that the baffle 14 is connected to the bottom wall of the box body 11 through the connecting portion 142. Exemplarily, holes can be opened in the connecting portion 142 and the bottom wall of the box body 11 respectively, so as to realize the connection between the two by using bolts or other connecting parts, and the connection method is simple, can be flexibly disassembled, and is convenient for users to operate.

[0051] In some embodiments, the shielding portion 141 includes an upper area 143 and a lower area 144, the connecting portion 142 is connected to the lower area 144, the lower area 144 is separated from the heat dissipation side wall 12, the upper area 143 is connected to the upper side of the lower area 144, and the upper area 143 is configured to extend obliquely from bottom to top toward the direction close to the heat dissipation side wall 12.

[0052] like Figure 2As shown, the shielding portion 141 can be divided into two parts, namely an upper area 143 and a lower area 144. The upper area 143 and the lower area 144 are both constructed in a long strip shape. The upper area 143 is inclined relative to the vertical direction, and the lower area 144 is vertically arranged. The upper area 143 is inclined from the plane where the lower area 144 is located toward the heat dissipation side wall 12, and the inclination angle is less than 90 degrees, that is, the angle between the upper area 143 and the lower area 144 is an obtuse angle. The upper edge of the upper area 143 can be tightly attached to the heat dissipation side wall 12 or form a small gap with the heat dissipation side wall 12 to prevent open flames or rainwater entering the heat dissipation air duct 131 from entering the interior of the box body 11 through the gap between the upper area 143 and the heat dissipation side wall 12, thereby improving the fire and water prevention effects.

[0053] Thus, the heat dissipation duct 131 formed between the baffle 14 and the heat dissipation side wall 12 is constructed to gradually increase from top to bottom, and the top of the heat dissipation duct 131 can be closed or have only a very small gap, so that after the external open flame or rainwater enters the installation cavity 111 from the heat dissipation hole 121, it can flow downward under the action of the baffle 14, and will not flow upward to the heat-generating component 13 or directly act on the heat-generating component 13 in the horizontal direction, greatly improving the shielding effect of open flame or rainwater. At the same time, the lower area 144 is separated from the heat dissipation side wall 12 to form the heat dissipation duct 131, which is conducive to heat dissipation.

[0054] In some embodiments, the height of the upper edge of the upper region 143 is higher than the height of the upper edge of the heat dissipation hole 121. It is understandable that the upper edge of the upper region 143 is higher than the upper edge of the heat dissipation hole 121, which can prevent open flames or rainwater from entering the heat dissipation hole 121 and flowing from the upper part of the baffle 14 to the heating element 13, thereby effectively shielding the open flames or rainwater and preventing the heating element 13 from being ignited or failing due to water ingress. It should be noted that the upper edge of the upper region 143 is higher than the upper edge of the heat dissipation hole 121, and after the open flames or rainwater enter the heat dissipation hole 121, they can flow downward under the guidance of the upper region 143. During the flow, the height of the rainwater decreases or the open flames gradually extinguish, and the heating element 13 will not be damaged.

[0055] In some embodiments, the shielding portion 141 further includes a connecting flange 145 located at the bottom of the lower region 144, the connecting flange 145 is bent and connected to the connecting portion 142, and the lower edge of the lower region 144 is spaced apart from the bottom wall of the box body 11. Figure 2 As shown, a connecting flange 145 is provided in the lower area 144 of the shielding portion 141, and the connecting flange 145 is configured to extend downward from the lower area 144, that is, to extend from the lower area 144, and a heat dissipation gap is formed between the lower area 144 and the bottom wall of the box body 11 on the left and right sides of the connecting flange 145, so that the heat generated by the heat-generating component 13 can enter the heat dissipation duct 131 therefrom, and then be discharged through the heat dissipation hole 121.

[0056] The connecting flange 145 is connected to the connecting portion 142 by bending, that is, the angle between the connecting flange 145 and the connecting portion 142 may be 90 degrees, and the connecting flange 145 and the connecting portion 142 are constructed as one body to enhance the overall structural strength of the baffle 14 .

[0057] In some embodiments, the shielding portion 141 is provided with a first clamping portion, and the heat dissipation side wall 12 is provided with a second clamping portion, and the first clamping portion and the second clamping portion are clamped and matched. Specifically, the first clamping portion and the second clamping portion can be respectively provided on the shielding portion 141 and the heat dissipation side wall 12, the first clamping portion can be provided to extend from the baffle 14, and the second clamping portion can be provided to be an opening, the first clamping portion passes through the second clamping portion to achieve matching, and the baffle 14 is connected to the box body 11 through the first clamping portion and the second clamping portion, so as to further improve the connection strength and connection stability.

[0058] That is, the connection between the baffle 14 and the box body 11 is not only connected at the bottom wall of the box body 11 through the connecting portion 142, but also connected at the heat dissipation side wall 12 through the cooperation of the first clamping portion and the second clamping portion. The connection is performed at multiple positions to improve the reliability of the connection.

[0059] like Figure 4 and Figure 7 As shown, the first clamping portion and the second clamping portion can be set to two, and a first clamping portion is respectively provided at the left and right ends of the shielding portion 141, and a second clamping portion is respectively provided at the left and right ends of the heat dissipation side wall 12. The setting positions of the two first clamping portions and the two second clamping portions correspond one to one. The cooperation between the first clamping portion and the second clamping portion can not only enhance the connection strength between the baffle 14 and the box body 11, but also limit the installation position of the baffle 14 to improve the accuracy of the installation position.

[0060] In some embodiments, the first clamping portion has a hook 146, and the second clamping portion is configured as a hanging groove 147, and the hook 146 is hung on the hanging groove 147. Thus, the baffle 14 can be hung on the heat dissipation side wall 12 through the cooperation between the hook 146 and the hanging groove 147. Specifically, Figure 4-Figure 5 As shown, the first clamping portion is constructed as a hook 146, which is arranged at the end of the lower area 144, and the hook 146 protrudes toward the heat dissipation side wall 12 relative to the lower area 144, and the second clamping portion is constructed as a hanging groove 147, and the hanging groove 147 penetrates the heat dissipation side wall 12 along the thickness direction, so that when the baffle 14 and the box body 11 are installed, the hook 146 can be extended toward the hanging groove 147, and it is convenient for the limiting protrusion at the bottom of the hook 146 to be limited and hung at the hanging groove 147.

[0061] Thus, part of the weight of the baffle 14 can be borne on the heat dissipation side wall 12 through the hook 146, and the hook 146 is facilitated to cooperate with the inner wall of the hanging groove 147, so that the hanging groove 147 can limit the hook 146 and the baffle 14, thereby preventing the baffle 14 from shaking in the box body 11 and misaligning with the heat dissipation hole 121, thereby ensuring the installation stability of the baffle 14.

[0062] Or, the first clamping portion has a clamping flange 1461, the second clamping portion is configured as a clamping groove, and the clamping flange 1461 is clamped and connected to the clamping groove. Specifically, Figure 7 As shown, the first clamping portion can also be constructed as a clamping flange 1461, and the second clamping portion can also be constructed as a clamping groove. The clamping connection between the clamping flange 1461 and the clamping groove can also realize the connection between the baffle 14 and the box body 11 on the heat dissipation side wall 12 and limit the installation position of the baffle 14. The structure is simple and the clamping method is easy to achieve quick installation.

[0063] Specifically, Figure 7 As shown, two snap-fit ​​flanges 1461 are provided and are respectively located at the two ends of the lower area 144, wherein a side panel portion 151 is also connected between the snap-fit ​​flange 1461 and the lower area 144, and the two side panel portions 151 at the two ends of the lower area 144 can also play a role in shielding and guiding the open flame or rainwater entering the heat dissipation hole 121, thereby preventing the open flame or rainwater from spreading in large quantities from the two ends of the baffle 14, and enhancing the waterproof and fireproof effects.

[0064] In some embodiments, there are multiple connecting parts 142, and the multiple connecting parts 142 are spaced apart and distributed. It is understandable that the connecting parts 142 can be set to multiple, and the multiple connecting parts 142 can realize the connection between the baffle 14 and the box body 11 at multiple positions, which can improve the connection strength. At the same time, the multiple connecting parts 142 are spaced apart and distributed, which can improve the connection stability, and the space between the lower area 144 and the bottom wall of the box body 11 is divided into multiple spaces, that is, the heat emitted by the heat-generating components 13 can enter the heat dissipation duct 131 from these multiple spaces, and then enter the heat dissipation holes 121 to be discharged.

[0065] Specifically, Figure 3 As shown, there are two connecting parts 142, and the two connecting parts 142 are spaced apart and distributed. The separately arranged connecting parts 142 can make the connection between the baffle 14 and the box body 11 more stable, and improve the connection strength and stability. At the same time, the two connecting parts 142 divide the space between the lower area 144 and the bottom wall into three parts, that is, heat can enter the heat dissipation duct 131 from these three parts, and then enter the heat dissipation hole 121 to be discharged.

[0066] In some embodiments, the connecting portion 142 is provided with a connecting hole 148, and the connecting hole 148 is used to pass a connecting piece connected to the box body 11. Specifically, the connecting portion 142 is suitable for connecting the baffle 14 to the bottom wall of the box body 11, such as Figure 3 As shown, a connecting hole 148 can be set on the connecting part 142, and bolts or other connecting parts are used to pass through the connecting hole 148 to connect to the bottom wall of the box body 11, and the baffle 14 is detachably connected to the box body 11, that is, the baffle 14 can be flexibly disassembled relative to the box body 11, which is convenient for user operation.

[0067] In some embodiments, the shielding portion 141 is provided with reinforcing ribs 149 , which can enhance the structural strength of the shielding portion 141 and avoid damage due to fatigue fracture, thereby improving the structural strength of the baffle 14 and avoiding failure of the baffle 14 .

[0068] It can be understood that the shielding portion 141 can withstand the impact from external rain or open flames, and withstand the heat impact in the installation cavity 111. By setting the reinforcing ribs 149, the impact resistance and overall structural strength of the shielding portion 141 are enhanced, thereby ensuring the shielding effect of the baffle 14 and improving the reliability of the baffle 14.

[0069] In some embodiments, the reinforcing rib 149 includes a first rib 1491 and a second rib 1492, wherein the first rib 1491 is extended along a first direction, the second rib 1492 is extended along a second direction, and the first rib 1491 and the second rib 1492 intersect. Specifically, the first rib 1491 is arranged in a direction parallel to the heat dissipation side wall 12, the second rib 1492 extends from the lower area 144 of the baffle 14 toward the upper area 143, and is arranged in close contact with the baffle 14, the first rib 1491 and the second rib 1492 intersect, that is, the first rib 1491 and the second rib 1492 are arranged in different directions, so that the structural strength of the baffle 14 can be strengthened in different directions, thereby further improving the structural strength.

[0070] It is understandable that the number of reinforcement ribs 149 can be multiple. As the number of reinforcement ribs 149 increases, the effect of improving the structural strength will also increase. Figure 7-Figure 8 As shown, the number of the first ribs 1491 is two, the number of the second ribs 1492 is three, and the two first ribs 1491 are spaced apart, and the three second ribs 1492 are spaced apart, that is, reinforcing ribs 149 are arranged at multiple positions to strengthen the strength of the baffle 14, thereby effectively improving the structural strength of the baffle 14.
