Description
Technical field
The utility model particularly belongs to a kind of high heat dissipation thin film capacitor.
Background technique
Thin film capacitor in the prior art causes failure ratio higher due to the deficiency of heat dissipation performance, and performance is unstable,
Service life is short.Its reason is that thin film capacitor has certain heating power, and the film thermal conductivity of thin film capacitor all compares
Difference causes thin film capacitor fever more serious.
Utility model content
The purpose of this utility model is to provide a kind of high heat dissipation thin film capacitors, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, the utility model provides the following technical solutions: the utility model discloses a kind of high heat dissipations
Thin film capacitor, including ontology, ontology are equipped with positive wire and negative wire, and ontology is equipped with sealing cover, in sealing cover
Cartridge fuse there are two dresses is fixed in face, and fuse is wrapped on cartridge fuse, and fuse passes through conductive sheet and connects capacitor core, capacitance core
The top of son is equipped with thermal grease, is covered with polypropylene metallized film on capacitor core, the both sides of polypropylene metallized film are equal
Even to arrange heat-dissipating pipe, ontology is equipped with heat release hole, and heat-dissipating pipe connects heat release hole, is equipped with one layer of insulation sleeve in vivo, insulation sleeve with
It is bonded between capacitor core by fixative, the outside of ontology is equipped with one layer of cooling fin.
Further improvement of the utility model is: heat-dissipating pipe is connected with cooling fin.
Further improvement of the utility model is: positive wire connects fuse with negative wire.
Further improvement of the utility model is: fixative is random polypropylene APP-L.
Compared with prior art, the utility model has the beneficial effects that
The utility model structure is simple, by the thermal grease, heat-dissipating pipe and cooling fin of setting, accelerates the heat of capacitor
Speed is distributed, the polypropylene metallized film of use can increase the service life of capacitor, and small, high insulation is lost, excellent
Flame-proof damp-proof performance and good self-healing performance.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of high heat dissipation thin film capacitor, including ontology 1, ontology 1 is equipped with just
Pole lead 2 and negative wire 12, ontology 1 are equipped with sealing cover 7, and there are two cartridge fuse 13, fuses for the fixed dress in the inside of sealing cover 7
Fuse 4 is wrapped on pipe 13, fuse 4 passes through conductive sheet 3 and connects capacitor core 5, and the top of capacitor core 5 is equipped with heat dissipation silicon
Glue 14, is covered with polypropylene metallized film 6 on capacitor core 5, the both sides of polypropylene metallized film 6 it is evenly distributed heat-dissipating pipe
10, ontology 1 is equipped with heat release hole 15, and heat-dissipating pipe 10 connects heat release hole 15, is equipped with one layer of insulation sleeve 9 in ontology 1, insulation sleeve 9 with
It is bonded between capacitor core 5 by fixative 8, the outside of ontology 1 is equipped with one layer of cooling fin 11.
In the utility model, heat-dissipating pipe 10 is connected with cooling fin 11, and positive wire 2 and negative wire 12 connect fuse 4,
Fixative 8 is random polypropylene APP-L.
Working principle: being attracted each other by positive wire and negative wire, and capacitor is made to generate electricity, capacitor core fever
Hot gas is discharged by thermal grease, heat-dissipating pipe and cooling fin when serious, increases the service life of capacitor, overvoltage protection dress
Higher effective current can be born by setting, and can be cut off the power in time, prevent from exploding.
In conclusion the utility model structure is simple, by the thermal grease, heat-dissipating pipe and cooling fin of setting, accelerate electricity
The heat of container distributes speed, and the polypropylene metallized film of use can increase the service life of capacitor, is lost small, high absolutely
Edge, excellent flame-proof damp-proof performance and good self-healing performance.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
