Abstract
The invention discloses a naturally heat radiation structure of an inverter die-casting box. The naturally heat radiation structure comprises a box and radiating fins, the radiating fins are distributed at the back of the box, and a natural heat radiation air channel is constituted by the radiating fins and the box. The radiating fins are arranged at different positions of the air channel from bottom to top, the length of a starting section of the air channel is 32% of the length of the overall fins and the tooth height of the starting section of the air channel is 22-26mm (milimeter); the length of a middle section is 38% of the length of the overall fins and the tooth height of the middle section is 36-42 mm; and the length of a tail section is 30% of the length of the overall fins and the tooth height of the tail section is 55-65mm. The radiating fins on the surface of the inverter die-casting box are subjected to thermal and fluid dynamic coupling analysis, so that fluid frictional resistance loss is effectively lowered by the air channel constituted by the box and fins in specific shapes, more cold air is guaranteed to flow smoothly to the positions for heat exchanging, overall heat convection coefficients of the surfaces of the radiating fins are increased , and the heat exchange process is carried out more efficiently.
Description
Technical field
The present invention relates to inverter, be specifically related to a kind of inverter die casting casing natural heat dissipation structure.
Background technology
Inverter is a kind of direct current to be converted into the device of alternating current, is widely used at new energy field.Inverter is divided into coal electricity inverter, solar inverter, wind energy inverter and nuclear energy inverter according to the difference of energy source; Different according to purposes, be divided into independent control inverter and combining inverter.Various inverters all are provided with a large amount of electronic components in casing, in use inevitably can produce certain heat, especially in the large-sized photovoltaic grid-connected system, high-power combining inverter can produce a large amount of heats in running, heat accumulation will affect the running of whole photovoltaic generating system.For this problem, traditional solution is in tank surface radiated rib to be set to carry out natural heat dissipation, but the height of these radiated ribs is identical, lack the cross discipline Quantitative design, cause the air channel on-way resistance large, and whole fin efficiency is low, radiating effect is not good.
Summary of the invention
The present invention is directed to above-mentioned shortcoming, a kind of inverter die casting casing natural heat dissipation structure is provided, purpose is: solve existing inverter die casting casing natural heat dissipation fin: the problem that radiating effect is not good.
Technical solution of the present invention:
A kind of inverter die casting casing natural heat dissipation structure, comprise casing and radiated rib, it is characterized in that: described radiated rib is distributed in box back surface, radiated rib and casing form the natural heat dissipation air channel, described radiated rib is at the diverse location in air channel from bottom to top, the air channel the initial segment: this section fin length accounts for 32% of integral ribs leaf length, and tooth depth is 22～26mm; The stage casing, air channel: this section fin length accounts for 38% of integral ribs leaf length, and tooth depth is 36～42mm; The air channel rear: this section fin length accounts for 30% of integral ribs leaf length, and tooth depth is 55～65mm.
The structure in the natural heat dissipation air channel that described radiated rib and casing form is open distribution from bottom to top.
Beneficial effect of the present invention:
The present invention carries out calorifics and fluid mechanics coupling analysis with the radiated rib of inverter die-cast cage surface, make the air channel of the fin composition of casing and given shape effectively reduce the fluid friction loss, guarantee that more cold airs flow to smoothly each position and carry out heat exchange, thereby improved the bulk convection heat exchange coefficient on radiated rib surface, make that heat exchanging process is more efficient to carry out, reduced simultaneously material and weight.With respect to conventional tank Fin structure, obtained better radiating effect.
Description of drawings
Accompanying drawing is perspective view of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As shown in the figure, a kind of inverter die casting casing natural heat dissipation structure, comprise casing 1 and radiated rib 2, described radiated rib 2 is distributed in casing 1 back side, radiated rib 2 and casing 1 form the natural heat dissipation air channel, described radiated rib 2 is at the diverse location in air channel from bottom to top, and the air channel the initial segment: this section fin length accounts for 32% of integral ribs leaf length, and tooth depth is 22～26mm; The stage casing, air channel: this section fin length accounts for 38% of integral ribs leaf length, and tooth depth is 36～42mm; The air channel rear: this section fin length accounts for 30% of integral ribs leaf length, and tooth depth is 55～65mm.The structure in the natural heat dissipation air channel that described radiated rib 2 and casing 1 form is open distribution from bottom to top.
The present invention carries out calorifics and fluid mechanics coupling analysis with the radiated rib of inverter die-cast cage surface, the given shape radiated rib is distributed in inverter die-cast cage surface, make that the natural heat dissipation heat exchanging process is more efficient to carry out, thereby obtain stronger radiating effect.
More than be one embodiment of the present invention, the present invention includes but be not limited to above execution mode, any simple modification of carrying out on basis of the present invention and replace and all belong to protection scope of the present invention.
