[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 2-3 , a schematic diagram of the overall structure of a heat dissipation device is provided, a heat dissipation device, comprising, a containing mechanism 100, comprising a fixing component 101 arranged in the containing mechanism 100, and a storage component 102 arranged outside the containing mechanism 100; and a heat dissipation mechanism 200, comprising a first heat dissipation plate 201 and a second heat dissipation plate 202 arranged on the containing mechanism 100, and a baffle 203 arranged on the first heat dissipation plate 201 and the second heat dissipation plate 202, wherein the purpose of setting the storage component 102 is to organize the messy wires and cables in the electrical control box in an orderly manner to prevent them from being entangled, and the purpose of setting the heat dissipation mechanism 200 is to increase the heat dissipation rate of the electrical control box, avoid the internal temperature of the containing mechanism 100 from being too high, reduce safety hazards and help to increase the service life of the electrical control box.

[0031] Specifically, the accommodating mechanism 100, the first heat sink 201, and the second heat sink 202 are all made of alloy material. The alloy material is used because metal has good thermal conductivity and the cost of alloy is low, which controls the cost while ensuring heat dissipation. The baffle 203 is U-shaped. The U-shape is used here because it has a simple structure and can block dust from entering.

[0032] Furthermore, the first heat sink 201 and the second heat sink 202 are symmetrically arranged, and a plurality of strip holes 204 are arranged on the first heat sink 201 and the second heat sink 202 , wherein the purpose of providing a plurality of strip holes 204 is to accelerate heat dissipation.

[0033] Operation process: The heat generated inside the electrical control box will be conducted to the accommodating mechanism 100, the first heat sink 201 and the second heat sink 202, wherein the strip holes 204 can accelerate the heat dissipation, and the baffle 203 will block the dust outside to avoid a large amount of dust accumulation in the electrical control box.

[0034] Example 2

[0035] Reference Figure 1This embodiment is different from the first embodiment in that: a fixing assembly 101 includes a fixing plate 103 arranged in the accommodating mechanism 100, and a component fixing sheet 104 arranged on the fixing plate 103, and a component fixing hole 104-a is provided on the component fixing sheet 104. The purpose of the arrangement here is to install and place the electrical components in the electrical control box in an orderly manner, improve the aesthetics, avoid clutter, and avoid difficulty in finding when a fault occurs.

[0036] Specifically, the number of fixing plates 103 is set to at least three groups, and the number of component fixing plates 104 arranged on the same fixing plate 103 is at least four groups. The quantity limitation is made here because only by setting up enough components can the electrical components be installed and arranged in an orderly manner.

[0037] The rest of the structure is the same as that of Example 1.

[0038] Operation process: first install the fixing plate 103 inside the accommodating mechanism 100, then install the component fixing plate 104 on each fixing plate 103, and then arrange the electrical components in the electrical control box in order and install and fix them on the component fixing plate 104, so as to improve the orderliness and aesthetics of the interior of the electrical control box, which is conducive to troubleshooting.

[0039] Example 3

[0040] Reference Figure 3-5 This embodiment is different from the above embodiments in that: the storage component 102 includes a storage frame 105, and a storage shaft 105a arranged in the storage frame 105, the storage shaft 105a is provided with a storage roller 105b, and the storage roller 105b is provided with a limiting plate 105c; the accommodating mechanism 100 is provided with a wire outlet hole 106, and the purpose of providing the wire outlet hole 106 is to extend the rolled-up wires and cables into the accommodating mechanism 100 through the wire outlet hole 106 and then connect them with the electrical components.

[0041] Specifically, a limiting hole 105c-1 is provided on the limiting plate 105c, and a plurality of limiting grooves 105c-2 arranged in a ring shape are provided on the accommodating mechanism 100. The limiting hole 105c-1 and the corresponding limiting groove 105c-2 are inserted with the same limiting pin 105c-3. The limiting mechanism arrangement here can fix the wires and cables after they are rolled up to prevent them from rotating when stationary, thereby causing the wires and cables to scatter.

[0042] The rest of the structure is the same as that of Example 2.

[0043] Operation process: Wind the wires and cables around the take-up roller 105b and then rotate the limit plate 105c to reel in the cables. After leaving a suitable length, extend the excess length of the wires and cables from the outlet hole 106 and connect them to the electrical components. After the connection work is completed, insert the limit pin 105c-3 into the limit hole 105c-1 on the limit plate 105c and the limit groove 105c-2 corresponding to the limit hole 105c-1. At this time, the winding and fixing of the wires and cables are completed.

[0046] Specifically, the accommodating mechanism 100 is provided with a first wire threading hole 301a and a second wire threading hole 302a, and the first accommodating component 301 and the second accommodating component 302 are respectively installed in the accommodating mechanism 100 through the first wire threading hole 301a and the second wire threading hole 302a. The setting of the first wire threading hole 301a and the second wire threading hole 302a here is convenient for connecting wires from here, so as to facilitate the driving connection between the driving source and the air-cooled fan blades 303.

[0047] Furthermore, air-cooling blades 303 are provided in the first accommodating component 301 and the second accommodating component 302, and protective plates 304 are provided on the first accommodating component 301 and the second accommodating component 302, wherein the protective plates 304 are provided to prevent the wires and cables inside the accommodating mechanism 100 of the high-voltage electrical control box from being damaged by the air-cooling blades 303, thereby playing a certain protective role.

[0048] The rest of the structure is the same as that of Example 3.

[0049] Operation process: The air-cooling fan blades 303 are driven to rotate by threading through the first threading hole 301a and the second threading hole 302a, so as to cool the interior of the electrical control box with air. Two sets of fans are used for air cooling at the heat dissipation rate of the material of the electrical control box itself, thereby achieving the purpose of accelerating heat dissipation.
