Abstract
The utility model discloses a transformer structure used in a switching power supply. According to the structure, a whole transformer is arranged in a heat dissipation shell, and thermal conductivity potting glue is filled between the transformer and the heat dissipation shell. By the transformer structure used in the switching power supply, an aim of preventing over-high internal local temperature of the switching power supply due to a poor ventilation effect or even no ventilation between the inner side and outer side of the switching power supply is fulfilled, and a phenomenon that the reliability and service life of the switching power supply are influenced because heat generated by the transformer is accumulated is prevented.
Description
Technical field
The utility model relates to transformer device structure, refers more particularly to the transformer device structure that is used for needs reinforcement heat radiation in the Switching Power Supply.
Background technology
At present; The mounting means of transformer generally is directly to weld in the circuit board or be directly installed in the cabinet through folder is installed through skeleton in the Switching Power Supply; If inside and outside well-ventilated of power supply; Transformer can not influence the reliability of Switching Power Supply complete machine because of the heat of iron loss and copper loss generation can exchange to the outside rapidly.And (require to be the power supply more than the IP55 like classification of waterproof for inside and outside ventilation effect difference even the power supply that do not have a ventilation; Complete machine is generally taked all-sealed structure); The heat that transformer produces will be accumulated in transformer and Switching Power Supply is inner; Cause local temperature too high, have a strong impact on the reliability and the useful life of Switching Power Supply.
The utility model content
The purpose of the utility model be to provide a kind of heat dispersion good be used for the transformer device structure in the Switching Power Supply.
For addressing the above problem, the utility model has adopted following technical scheme.
Be used for the transformer device structure in the Switching Power Supply, be characterized in: transformer integral body is placed in the heat-dissipating casing, and between transformer and heat-dissipating casing, is filled with the heat conduction casting glue.
Further, the aforesaid transformer device structure that is used in the Switching Power Supply, wherein: described heat-dissipating casing is forward and backward both ends open, the copper or aluminum shell of the loop-like structure of all the other side-closed.
The beneficial effect of the utility model is: the above-mentioned transformer device structure that is used in the Switching Power Supply; During use its integral body is directly installed on the casing or radiator of Switching Power Supply; Like this; The heat that transformer work produces is passed to heat-dissipating casing rapidly through the heat conduction casting glue; Be passed to rapidly on the casing or radiator of Switching Power Supply through heat-dissipating casing again, reach the too high purpose of local temperature in the Switching Power Supply that prevents inside and outside ventilation effect difference even do not have ventilation, stop to produce reliability and the appearance of the situation in useful life that accumulation of heat impacts Switching Power Supply because of transformer.
Description of drawings
Fig. 1 is the described structural representation that is used for the transformer device structure in the Switching Power Supply of the utility model.
Fig. 2 is the structural representation of the heat-dissipating casing among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the described transformer device structure that is used in the Switching Power Supply of the utility model is done further detailed explanation.
Referring to shown in Figure 1, the described transformer device structure that is used in the Switching Power Supply of the utility model is placed on transformer 1 integral body in the heat-dissipating casing 2, and between transformer 1 and heat-dissipating casing 2, is filled with heat conduction casting glue 3.Referring to shown in Figure 2, described heat-dissipating casing 2 is forward and backward both ends open, the copper or aluminum shell of the loop-like structure of all the other side-closed.During making, a uncovered end of heat-dissipating casing 2 is sealed with adhesive tape or custom mold,, the adhesive tape or the mould that remove end-blocking after the curing of heat conduction casting glue are got final product from other end filling heat-conductive casting glue.In the use, heat-dissipating casing 2 is close on the radiating shell of Switching Power Supply, just can be realized splendid radiating effect.
Claims (2)
1. be used for the transformer device structure in the Switching Power Supply, it is characterized in that: transformer integral body is placed in the heat-dissipating casing, and between transformer and heat-dissipating casing, is filled with the heat conduction casting glue.
2. the transformer device structure that is used in the Switching Power Supply according to claim 1, it is characterized in that: described heat-dissipating casing is forward and backward both ends open, the copper or aluminum shell of the loop-like structure of all the other side-closed.
