Detailed description of the invention
Attached drawing 1 is the utility model section structural schematic diagram.
Specific embodiment
For the feature, technological means and specific purposes achieved, function that can further appreciate that the utility model, below
The utility model is described in further detail in conjunction with attached drawing and specific embodiment.
As shown in Fig. 1, the utility model discloses a kind of heat radiating type capacitor, including capacitor core body 10 and shell 1,
Contact conductor 11 is connected on capacitor core body 10, capacitor core body 2. is coated with encapsulated layer 9, and capacitor core body 10 is located at shell
In body 1, contact conductor 11 is pierced by outward from shell 1, and the inner sidewall of the shell 1 is equipped with upper faceplate 8 and lower faceplate 13, upper card
Vallecular cavity position 12 is equipped between wall 8 and lower faceplate 13, upper faceplate 8 and lower faceplate 13 are close to the encapsulated layer 9 on capacitor core body 10
Surface, upper faceplate 8 and lower faceplate 13 tilt respectively extends to vallecular cavity position 12, between having between 9 surface of vallecular cavity position 12 and encapsulated layer
Every, upper faceplate 8 and lower faceplate 13 are aluminum heat conducting plate, and 1 side wall of shell is equipped with the upper through-hole 7 and lower through-hole 2 being connected to vallecular cavity position 12,
The region that vallecular cavity position 12 is faced in shell 1 is equipped with heat guide plate 5, which extends to 1 outer surface of shell.Utilize slot
Chamber position and heat-conducting plate lead to vallecular cavity position for what most of heat was concentrated, are then transferred heat to outside shell by heat guide plate
Cooling, and heat concentrates on vallecular cavity position, forms the position of a current buffer, will not cause to capacitor core body excessive
It influences.
The upper through-hole and lower through-hole are set as skewed, and lower through-hole is obliquely installed from lower to upper, and upper through-hole inclines from top to bottom
Tiltedly setting, preferably setting are 45 degree of inclinations.
Air duct 4 is additionally provided in the shell 1,1 side wall of shell is equipped with air inlet 3 and air outlet 6, the air inlet and air outlet
