DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4The utility model provides a technical solution: a heat dissipation device for an outdoor power distribution cabinet using phase change materials, including a heat-conducting shell 1 sleeved on the outside of the equipment in the power distribution cabinet, the heat-conducting shell 1 tightly wraps the outside of the equipment to form an effective heat conduction channel; the heat-conducting shell 1 includes an enclosure formed by four plates and a side plate connected to the enclosure, the enclosure includes an outer wall 11 and an inner wall 12, and interconnected cavities 13 are arranged between the outer wall 11 and the inner wall 12 and inside the side plate, and the cavity 13 is uniformly filled with a filling layer 4 of a phase change material, such as paraffin. These phase change materials can quickly absorb heat and melt at high temperatures, and quickly absorb and store the heat generated by the equipment. As the heat continues to accumulate, the phase change material gradually changes from solid to liquid, and the absorption of latent heat in this process greatly improves the heat dissipation efficiency.

[0018] When the temperature inside the power distribution cabinet drops or the heat is dissipated to the outside air through the side panels of the heat-conducting shell 1, the phase change material will gradually return from liquid to solid, releasing the previously stored heat. This reversible phase change process enables the heat-conducting shell to continuously absorb and release heat, thereby maintaining the internal temperature of the power distribution cabinet relatively stable.

[0019] The combination of heat-conducting shell and phase change material not only greatly improves the heat dissipation efficiency, but also facilitates the long-term normal use of the equipment in the power distribution cabinet. By effectively reducing the temperature of the equipment, the service life of the equipment can be extended and equipment failures and damage caused by high temperature can be reduced.

[0020] A preferred technical solution is that a plurality of convex strips 3 are evenly arranged on the inner surface of the heat-conducting shell 1 enclosure, and the convex strips 3 form gaps between the heat-conducting shell 1 enclosure and the equipment, and these gaps are filled with thermally conductive silicone grease so that it can be fixed between the heat-conducting shell 1 and the equipment. The thermally conductive silicone grease has a high thermal conductivity rate, thereby making the heat conduction faster and the heat dissipation more efficient.

[0021] According to a preferred technical solution, a heat pipe end 2 is provided in the cavity 13, and the side plate includes an inner plate 14 and an outer plate 15. The cavity 13 is opened inside the inner plate 14, and a heat dissipation cavity is provided between the inner plate 14 and the outer plate 15. A heat pipe end 5 connected to the heat pipe end 2 is provided in the heat dissipation cavity, and the heat dissipation cavity is also filled with a phase change material filling layer 4. The heat pipe end 2 quickly conducts the heat absorbed by the phase change material in the cavity 13 to the heat pipe end 15 in the heat dissipation cavity, which can further improve the heat dissipation efficiency and enhance the heat dissipation effect.

[0022] A further preferred technical solution is that the heat pipe heat absorbing end 2 is in a square spring shape and surrounds the cavity 13 between the outer wall 11 and the inner wall 12, and the heat pipe heat dissipating end 5 is spirally arranged closely between the inner plate 14 and the outer plate 15. By extending the length of the heat pipe heat absorbing end 2 and the heat pipe heat dissipating end 5 to increase their surface areas, more heat can be absorbed and released in a short time, thereby further improving the heat dissipation effect.

[0023] An optional technical solution, in which the outer plate 15 is arranged on the outside of the distribution cabinet, and a plurality of heat sinks 6 are evenly arranged on the outer surface of the outer plate 15. The heat absorbed by the phase change material in the heat-conducting shell 1 and its cavity is conducted to the outer plate 15 through the heat pipe, and then diffused through the heat sink 6, thereby increasing the heat dissipation area, optimizing heat conduction, and being able to quickly transfer the absorbed heat to its surface, and then dissipate the heat into the air through natural convection.

[0024] As a further optional technical solution, a plurality of through grooves 7 are evenly formed on the upper surface of the heat sink 6, so as to further increase the heat dissipation area thereof.

[0025] The undisclosed parts in the present utility model are all prior art, and their specific structures, materials and working principles are not described in detail. Although the embodiments of the present utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the attached claims and their equivalents.
