Description
Technical field
The utility model is related to a kind of heat radiation sealed covers, particularly machine tool numerical control system heat radiation sealed structure.
Background technology
Digital control system is the important component of numerically-controlled machine tool, due to for a long time in the severe ring such as iron filings dust, humidity, corrosion
It working under the conditions of border, the failure of digital control system more than 70%, which is all intake, dust and heat dissipation are bad etc. influences and occurs,
Therefore, the working environment residing for digital control system is affected to its stability and service life.To meet digital control system electronics device
Part cooling requirements have and are both provided with heat emission hole, the warps such as external metallic dust, steam on the housing set outside digital control system
Heat emission hole enters in housing apposition in electronical elements surface, when accumulation to a certain extent when short circuit can be made to discharge, cause to count
Control system electronics damage.
The content of the invention
Not only there is good heat dissipation performance the purpose of this utility model is to provide a kind of, but can by digital control system with
The machine tool numerical control system heat radiation sealed structure of external environment isolation.
The technical solution of the utility model is：A kind of machine tool numerical control system heat radiation sealed structure, it is special including housing
Sign sets the housing of digital control system circuit board as seal casinghousing in being, the shell with electronic device opposite side on digital control system circuit board
