Detailed Description

The invention is further described with reference to the following figures and examples.

Example 1

A ventilation and heat dissipation structure of a dry rectifier transformer for variable frequency speed regulation comprises a cuboid protective cover 1, wherein the dry rectifier transformer is fixedly arranged on the bottom surface in the protective cover 1, a heat dissipation pipe 2 is arranged on the inner wall of the protective cover 1, the head end of the heat dissipation pipe 2 penetrates through the side wall of the protective cover 1 to be communicated with a pump, and the tail end of the heat dissipation pipe 2 penetrates through the side wall of the protective cover 1 to extend outwards; a housing 3 is mounted on the outside of the protection cover 1, and the pump is mounted in the housing 3.

Further, in the present embodiment, the radiating pipe 2 is distributed on the left side wall, the right side wall and the top wall inside the protective cover 1, and the radiating pipe 2 is distributed in zigzag shape on each wall. The reciprocating return distribution of the radiating pipe 2 can prolong the installation distribution length of the radiating pipe 2, thereby improving the heat exchange efficiency. A plurality of heat absorbing fins 21 are disposed on the outer wall of the heat dissipating pipe 2. The heat absorbing sheet 21 can increase the heat exchange area of the heat exchange tube and improve the heat dissipation speed in the protective cover 1.

In this embodiment, the pump is an air pressure pump 4, a filter screen 5 is installed on the side wall of the housing 3, and an air inlet of the air pressure pump 4 is installed at the filter screen 5. Air-pressure pump 4 inhales from the external world from filter screen 5, filter screen 5 can be with the large granule impurity in the air for example little branch, separation such as little leaf, air-pressure pump 4 is in the heat exchange tube with the outside air suction, carry out the heat exchange through the hot-air in heat exchange tube wall and the protection casing 1, finally through the tip discharge protection casing 1 of cooling tube 2 behind the air absorbed heat in the heat exchange tube wall, whole radiating process is in the state of isolated outside air in the protection casing 1, can not have dust etc. to get into in the protection casing 1. Three branch outlet pipes 6 are arranged on the radiating pipe 2, and the installation positions of the branch outlet pipes 6 are respectively as follows: the left side wall, the right side wall and the top wall of the protective cover 1; the branch air outlet pipes 6 penetrate through the corresponding walls and extend out of the protective cover 1.

Example 2

In this embodiment, the pump is water pump 7, water inlet pipe 8 of water pump 7 downwardly extends into with the underground water pipeling intercommunication, the end of cooling tube 2 is outlet pipe 9, outlet pipe 9 downwardly extends into with the underground water pipeling intercommunication. Groundwater is from 7 suction cooling tubes 2 of water pump, and rivers absorb the heat in the protection casing 1 in cooling tube 2, again through outlet pipe 9 flow in the underground water pipeling again, this kind of hydrologic cycle does not contact with the external world, and water can reuse, does not produce the convection current with outside air in the protection casing 1, prevents that protection casing 1 from having a large amount of dusts to fall into.
