Description
Technical field
The present invention relates to a kind of capacitor, specifically relate to a kind of high frequency induction heating temperature control type capacitor.
Background technology
In HF induction heating apparatus, the electric capacity of using as resonance, according to the size of power and side circuit use different, capacity requirement has between 0.01uF to 2000uF, voltage is between 400V to 4000V.Its common feature is, requires frequency height, voltage height, and electric current is big, and dv/dt is big, low-loss, rapid heat dissipation.
General high frequency induction heating capacitor commonly used comprises housing, electric exit, and is arranged on the capacitor core group in the housing, adopts oiling encapsulation blast resistance construction in the housing; On radiating mode, people often are covered with the whole casing surface to cooling water channel.1), capacitor adopts oiling encapsulation blast resistance construction the capacitor of said structure has the following disadvantages:, its complex manufacturing technology is big with volume, installs and uses very inconvenient; 2), on radiating mode, cooling water channel is covered with the case surface of whole capacitor device, it has not only increased volume and cost, and also relative complex of technology.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of simple and reasonable for structure, be convenient to install and use, when reducing volume, can reduce a kind of high frequency induction heating temperature control type capacitor of manufacturing cost.
The object of the present invention is achieved like this:
A kind of high frequency induction heating temperature control type capacitor; comprise housing, electric exit; and be arranged on capacitor core group in the housing; also include heat conductive flame-retarding epoxy resin; heat conductive flame-retarding epoxy resin is poured in the capacitor core group housing on every side; be equiped with the cooling water channel copper pipe near electric exit side in the housing; extend outside the housing at the two ends of cooling water channel copper pipe; be provided with copper strips between described electric exit and the capacitor core group and be connected, also be provided with the temperature protection switch that is electrically connected with copper strips on the electric exit.The capacitor of this structure only needs in the case top position near electric exit the cooling water channel copper pipe to be set, and can save cost, and the water journey of cooling water is shortened, and makes heat conduction rapider effectively, and radiating effect is better; And electric exit place is provided with temperature protection switch, can prevent to generate heat seriously to cause the technological deficiency of condenser failure.
Purpose of the present invention can also adopt following technical measures to solve:
Described cooling water channel copper pipe is electrically connected with capacitor core group negative pole end, and cooling water channel copper pipe water inlet end double as exit negative pole also extends outside the housing.Cooling water channel copper pipe double as exit negative pole, cost-saved.
For satisfying the requirement of HF induction heating apparatus, can take the multicore substring to compose in parallel a plurality of capacitor core groups to capacitance; As: require capacitance big, take the form of fuse group in parallel more; The concrete structure of its a plurality of capacitor core groups is, be provided with a plurality of capacitor core groups in the described housing, the capacitor core group of each is composed in series by a plurality of capacitor cores, each capacitor core group is anodal to be connected with copper strips, each copper strips connects electric exit corresponding on the housing respectively, each capacitor core group negative pole is connected with the cooling water channel copper pipe, makes a plurality of capacitor core groups be parallel and is arranged in the housing.Because the capacitor of this structure, its volume is generally bigger, and overcurrent is big, adopts above-mentioned cooling water channel and shell to be total to male end as negative pole, and a plurality of the drawing of the anodal employing of electric exit moved towards with scattered current.
Described electric exit can be the copper stud exit.
The invention has the beneficial effects as follows:
1), temperature control type capacitor of the present invention, adopt at housing directly to connect the cooling of cooling water channel copper pipe, and the cooling water channel copper pipe is as the common port heat radiation of capacitor, this rational water cooling mode has extremely effectively radiating effect; Moreover when the capacitor real work, the heating of capacitor each several part is extremely uneven, because current concentration effect and electromagnetic field of high frequency influence, the most serious part of generating heat is the position near electric exit, and in the capacitor bottom, caloric value is very little; In the prior art, people often are covered with the whole casing surface to cooling water channel, and the present invention, only need get final product at one section cooling water channel copper pipe of case top installing near electric exit, the double exit negative pole of doing of this section water channel copper pipe has so not only been saved cost, and the water journey of cooling water has been shortened, make heat conduction rapider effectively, radiating effect is better; Same, owing to be subjected to the influence of electromagnetic field of high frequency inductive loop, can be heated at the aluminium sheet of cover top portion, generally all can arrive more than 80 ℃, caloric value is very big, has increased energy consumption so greatly, has heated capacitor core again indirectly, for solving this, our metal shell top is not sealed, and directly with the epoxy resin pouring, can not have the inductive loop heating problems, energy consumption has reduced, and is also beneficial to the stable performance of electric capacity;
2), the temperature control type capacitor of this structure, by temperature protection switch being set, can preventing to generate heat serious and cause the technical problem of condenser failure at electric exit place; That is: at electric exit serial connection temperature protection switch, the electric capacity heating temp is elevated to a threshold value and just opens a way automatically, strengthen the reliability of electric capacity greatly, and do not need to adopt oily formula explosion-proof structure, directly adopt the dry type encapsulation of epoxy resin perfusion, reduced on the volume, installed and use more convenient;
3), the temperature control type capacitor of this structure, also be applicable in the HF induction heating apparatus, require the higher capacitor of capacitance, especially take the multicore substring to compose in parallel the capacitor of a plurality of capacitor core groups; Because the capacitor of this structure, volume is generally bigger, and overcurrent is big, adopts above-mentioned cooling water channel and shell to be total to male end as negative pole, and a plurality of the drawing of the anodal employing of electric exit moved towards with scattered current;
4), temperature control type capacitor of the present invention, only need the cooling water channel copper pipe is set, and, can realize above-mentioned beneficial effect at the electric exit serial connection temperature protection switch of correspondence in case top position near electric exit, it is simple and reasonable for structure.
