Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 5, the combined power transformer easy to dissipate heat of the present invention includes a case 1 and a transformer body 2. The transformer body 2 is arranged in the shell 1 through the fixing columns 3, supporting columns 4 are arranged on the periphery of the bottom of the shell 1, and the supporting columns 4 support the shell 1.

The first heat dissipating members 5 are provided on both side surfaces of the housing 1, and the first heat dissipating members 5 include a connecting plate 51 and a blower (not shown), and the connecting plate 51 is detachably mounted on both side surfaces of the housing 1. Specifically, two T-shaped clamping grooves 52 are formed in the connecting plate 51, two T-shaped clamping blocks 9 are arranged on the side surface of the shell 1, the T-shaped clamping grooves 52 are matched with the T-shaped clamping blocks 9, and a bearing plate 10 is arranged at the bottom of each T-shaped clamping block 9. The T-shaped clamping grooves 52 on the connecting plate 51 correspond to the T-shaped clamping blocks 9 on the two sides of the shell 1, so that the connecting plate 51 can be installed on the two sides of the shell 1, the dismounting and the installation are convenient, and the bearing plate 10 plays a role in supporting the connecting plate 51.

The fan is embedded on the central surface of the connecting plate 51, the surface of the connecting plate 51 is provided with two L-shaped supporting strips 55, and a dust screen 56 is arranged between the L-shaped supporting strips 55. The bottom of the L-shaped support bars 55 have stoppers (not shown) for preventing the dust-proof net 56 from falling off from the bottom of the L-shaped support bars 55, and the dust-proof net 56 is inserted between the L-shaped support bars 55.

An air outlet 6 is formed in the bottom of the shell 1, air inlets 7 are formed in two sides of the shell 1, and the air outlet 6 of the fan corresponds to the air inlets 7 in position. The fan is started, and the wind blown in by the fan blows in the shell 1 from the air inlet 7, so that the air inside the shell 1 circulates, the heat generated by the transformer body 2 is dissipated, and finally the hot air is blown out from the air outlet 6. When first radiator unit 5 needs to be cleaned, first, connecting plate 51 is moved upward, and T-shaped slot 52 is moved upward along T-shaped block 9, so that first radiator unit 5 can be taken out, and air inlet 7 is cleaned. Certainly also can take out dust screen 56 from two L shape support bars 55, clean dust screen 56 and fan, install again after the cleanness, further improve first radiator unit 5's radiating efficiency, the radiating effect is good.
