Preferably, multiple arcs thermal insulation board is installed, arc thermal insulation board is to far from controller housing in controller housing
One lateral process of chamber center.
Preferably, the periphery of controller housing is equipped with multiple hemispherical projections.
The present invention is easy to use, and stable structure has effectively deposited into air circulation.The present invention is led using radiating groove and annular
It flows chamber cooperation and increases heat dissipation area of the invention, be connected to radiating groove using annular diversion cavity, promote controller housing air nearby
Circulation, it is multiple annular diversion cavities be sequentially distributed along controller housing length direction, can effectively reduce annular diversion cavity to this
The influence of invention overall stability, and annular diversion cavity reduces the thermally conductive distance in inner cavity of device shell processed, even and if present invention pendulum
Heat dissipation effect will not be influenced by putting inclination, reduce installation requirements of the invention.
Detailed description of the invention
Fig. 1 is a kind of controller architecture schematic diagram containing annular diversion cavity proposed by the present invention；
Fig. 2 is controller housing cross-sectional view；
Fig. 3 is A partial enlarged view in Fig. 2,
Specific embodiment
Shown in referring to FIG. 1, FIG. 2 and FIG. 3, a kind of controller containing annular diversion cavity proposed by the present invention, including control
Device main body, controller housing 2 and fixed auxiliary frame 3；
Fixed auxiliary frame 3 is mounted on controller housing 2, and controller main body is mounted in the inner cavity of controller housing 2；Control
2 periphery of device shell processed is equipped with multiple radiating grooves 21, and radiating groove 21 extends along 2 length direction of controller housing, controller housing 2
Multiple annular diversion cavities 22 are equipped in shell wall, annular diversion cavity 22 is around 2 inner cavity of controller housing, 22 edge of multiple annular diversion cavities
2 length direction of controller housing is sequentially distributed, and radiating groove 21 is connected to annular diversion cavity 22.
The present invention increases heat dissipation area of the invention using radiating groove 21 and the annular cooperation of diversion cavity 22, utilizes annular water conservancy diversion
Chamber 22 is connected to radiating groove 21, promotes the circulation of air near controller housing 2, multiple annular diversion cavities 22 are along controller housing 2
Length direction is sequentially distributed, and can effectively reduce the influence of annular 22 pairs of overall stability of the present invention of diversion cavity, and annular water conservancy diversion
Chamber 22 reduces the thermally conductive distance in inner cavity of device shell 2 processed.The present invention is easy to use, and stable structure has effectively deposited into air stream
It is logical.After improving cooling effect of the invention, is conducive to the present invention and sealing and structural strengthening is better achieved.
It further include multiple guiding devices in present embodiment, guiding device is mounted in annular diversion cavity 22；
Guiding device includes two mounting rings 41, diversion column 42, gravitation ball 43 and current limiting plate 44, two mounting rings 41
It is rotatably installed in annular diversion cavity 22, the both ends of diversion column 42 are separately connected two mounting rings 41, and diversion column 42 is equipped with storage
Recirculation hole, gravitation ball 43 are mounted in storage recirculation hole, and mounting ring 41 and the cooperation of diversion column 42 can increase radiating surface of the invention
Product, and air can be oriented to using the outer surface of diversion column 42, if diversion column 42 uses triangular prism, in order to realize this
Invention is put anyway, and diversion column 42 can play good guide functions, therefore gravitation ball 43 is mounted on storage recirculation hole
Interior, under the action of gravitation ball 43,43 side of gravitation ball is always located at whole lower section on diversion column 42, on combining air heats
