Abstract
A rectifier structure with high heat dissipation is characterized by comprising a circuit board, rectifier diodes and heating panels. The rectifier diodes are respectively arranged at positive heating panels and negative heating panels in a pressing manner, the upper side and the lower side of the circuit board are in circular arc shape, the heating panels are arranged on the circuit board in the axial direction of the circuit board, and radial air channels are formed among the heating panels. The circuit board is in the circular arc shape, and the area of each heating panel is increased under the condition that the inner space of a generator is changeless, so that the heat dissipation of a rectifier is improved, and the service life of the diode is prolonged.
Description
Technical field
The utility model is specifically related to a kind of rectifier structure of generator, particularly a kind of heat dissipation type high rectifier structure.
Background technology
The function of rectifier is that the three-phase alternating current that stator coil is produced utilizes the diode full-wave rectification to become direct current output.Wherein rectifier comprises circuit board, a plurality of rectifier diode and heating panel, and wherein rectifier diode is welded in respectively on the positive and negative heating panel, and press-fit approach is fixed on the circuit board, and the function of its heating panel is to distribute for the heat that rectifier is produced.General positive and negative heating panel is confined to spatial limitation, and majority designs with symmetric mode.
Present stage melancholy automobile is many functions because of inside increases, and it is big that power demands also progressively becomes, so generator constantly improves aspect exerting oneself for meeting power demands, but it is big more to exert oneself, the heat that is produced is also high more, if temperature is too high, the easy Yin Gaowen of the diode in the rectifier reduces useful life.
Summary of the invention
The utility model provides a kind of heat dissipation type high rectifier structure, and purpose is to solve the prior art problem, and a kind of rectifier structure with excellent heat dispersion performance is provided.
The utility model technical scheme that adopts of dealing with problems is:
The heat dissipation type high rectifier structure, include circular arc circuit board, positive heating panel and negative heating panel, wherein rectifier diode is welded in respectively on the positive and negative heating panel, after being fixed on circuit board with press-fit approach, diode is fixed with mode of welding and circuit board again, the side up and down of described circuit board is a circular arc, and heating panel is arranged on the circuit board along the axial direction of circuit board, and the edge forms the radial air passage between the heating panel.
The beneficial effects of the utility model: circuit board up and down side is a circular arc, and its heating panel area becomes big under the constant situation in generator inner space, increases the rectifier thermal diffusivity, has prolonged the useful life of diode.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Heat dissipation type high rectifier structure as shown in fig. 1 includes circuit board 1, rectifier diode and heating panel, and diode is fitted in respectively as on the anodal heating panel 21 and the heating panel 22 as negative pole, forms anodal diode 31 and negative pole diode 32.The side up and down of described circuit board 1 is a circular arc, and heating panel is arranged on the circuit board 1 along the axial direction of circuit board, and the edge forms the radial air passage between the heating panel.
Global design is a circular arc, can be provided with more heating panel on its rectifier under the constant situation in generator inner space, and it is big that the gross area of its heating panel becomes, and so just increased the rectifier thermal diffusivity, prolonged the useful life of diode.
