Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-5, a heat dissipation device for a motor includes a housing 10, a fixing plate 12 fixed to a bottom of the housing 10, and a plurality of heat dissipation fans 26 disposed inside the housing 10.

The inner side of the outer shell 10 is fixedly provided with a plurality of fixing bolts 11, the inner side of each fixing bolt 11 is fixedly connected with an inner frame 20, the inner side of each inner frame 20 is fixedly provided with a plurality of radiating fins 21, the inside of each radiating fin 21 is provided with a water through pipe 24 in a penetrating mode, the inner side of each water through pipe 24 is fixedly provided with a dustproof net 25, the inner frames 20 are fixed through the fixing bolts 11, the radiating fins 21 and the water through pipes 24 form a round heat exchange structure, and the dustproof net 25 is arranged inside to provide dustproof protection for the radiating fan 26.

Wherein, the one end of water service pipe 24 is provided with inlet tube 23, and the other end of water service pipe 24 is provided with outlet pipe 22, and inlet tube 23 sets up respectively in the both sides of shell 10 with outlet pipe 22, all communicates between the multilayer helical structure of water service pipe 24, and inlet tube 23 all communicates with water service pipe 24 with outlet pipe 22, can intake through inlet tube 23, and outlet pipe 22 goes out water, can form endless water-cooling structure after installing the pump body additional, can dispel the heat to the generator.

Wherein, the water service pipe 24 is a planar spiral structure, the surface of the heat sink 21 is provided with a through connection hole 211, the heat sink 21 is fixedly provided with a support plate 212 near one side surface inside the housing 10, the heat sink 21 is made of aluminum material, the support plate 212 is made of heat insulating material, the heat sink 21 is fixed outside the water service pipe 24 in a through manner, after the heat sink 21 is additionally arranged, the heat sink 21 is more densely attached near the center part due to circular distribution, during heat dissipation, the heat dissipation inside the heat sink is weaker, the heat dissipation outside the heat sink is faster, therefore, in the actual heat dissipation, a mild heat dissipation effect can be ensured, the situation of overhigh heat dissipation effect can not occur, and a stable heat dissipation effect can be ensured.

The supporting plate 212 is fixedly mounted on the inner frame 20, the fixing bolt 11 is a cylindrical bolt tube, a through bolt is arranged inside the fixing bolt 11 and fixedly connected with the inner frame 20, and the supporting plate 212 is used for supporting the radiating fins 21, so that the radiating fins 21 are prevented from being damaged in the using process.

The baffle 13 is further arranged inside the outer shell 10, the baffle 13 and the inner frame 20 are both in a rectangular frame structure, the baffle 13 and the inner frame 20 are tightly attached to limit the air outlet position of the heat dissipation fan 26, and it is ensured that the air blown by the heat dissipation fan 26 can be blown onto the cooling fins 21 and the water service pipe 24.

The working principle is as follows: when using, at first connect water pump and coolant tank at inlet tube 23, then be connected the pipeline of both sides with the water inlet and the delivery port of generator respectively, need to be connected the pipeline that outlet pipe 22 corresponds with the water inlet of generator, during the use, carry out endless rivers power take off through the water pump, the heat dissipation is then bloied the heat dissipation through heat dissipation fan 26, because fin 21 is planar circular setting with water service pipe 24, consequently, make the gap that water service pipe 24 that is close to the central point can ventilate less, and outside water service pipe 24 then can blow more wind, outside heat dissipation is better, when actually dispelling the heat, can externally carry out the heat dissipation of high strength, inside then guarantees the temperature and can not rise, guarantee stable radiating effect, avoid appearing overheated or the supercooled condition, the radiating effect is more stable.
