Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to a high-efficiency curved pipe radiator. Background Art

[0002] Switchgear is a type of electrical equipment whose primary function is to open and close, control, and protect electrical equipment during power generation, transmission, distribution, and conversion in power systems. Switchgear products feature high current ratings, high levels of enclosure protection, miniaturization, and, in some cases, sealed mechanisms. These factors all require effective heat dissipation management to limit temperature rises to within acceptable limits. Heat management is a challenging issue in switchgear. Excessive temperature rises accelerate component aging, degrading insulation performance and reliability. Taking measures to limit heat generation is only one aspect of the solution; strengthening and effectively dissipating heat is another crucial aspect.

[0003] Currently, the heat sources of switchgear in a stable state include Joule heating generated when conductors are energized, induction heating, and dielectric heat. Traditionally, convection is the primary heat dissipation method. During switchgear design, ventilation holes are created at the bottom of the switchgear, and ventilation slots are added to the contact box to direct cool air toward the hottest areas. This utilizes the chimney effect to increase air velocity and flow. However, due to the limited location and space for convection heat dissipation, traditional heat dissipation methods are not effective in dissipating heat from the switchgear quickly. Utility Model Content

[0008] Furthermore, the first horizontal segment, the first inclined segment, the second horizontal segment, the second inclined segment, the fourth inclined segment, the fourth horizontal segment, the third inclined segment and the third horizontal segment are integrally formed.

[0009] Furthermore, the locking plate is provided with a row of upper connection holes and a row of lower connection holes, the row of upper connection holes is composed of a plurality of upper connection holes arranged on the left and right, and the row of lower connection holes is composed of a plurality of lower connection holes arranged on the left and right, each curved heat dissipation tube corresponds to an upper connection hole and a lower connection hole, and the two ends of the curved heat dissipation tube are respectively connected to the upper connection hole and the lower connection hole.

The electrical components in the switch cabinet generate heat during operation. The heat in the switch cabinet enters the switch cabinet from the upper end of the curved heat dissipation tube along with the air and re-enters the switch cabinet from the lower end of the curved heat dissipation tube.
