Description

A kind of air-cooled circuit isolation structure
Technical field
The utility model is related to circuit board technology field, specially a kind of air-cooled circuit isolation structure.
Background technology
Circuit board can be described as printed substrate or printed circuit board (PCB), and FPC wiring boards are also known as FPC flexible PCB It is a kind of with height reliability, excellent flexible printed circuit made by with polyimides or polyester film as base material. With Distribution density is high, lightweight, thickness of thin, good bending property the characteristics of;With Rigid Flex (reechas, Soft and Hard combination plate)-FPC and PCB birth and development, expedited the emergence of Rigid Flex this new product.Therefore, Rigid Flex, is exactly FPC and rigid wiring board, through operations such as pressings, is combined one by related process requirement Rise, the wiring board with FPC characteristics Yu PCB characteristics of formation.
Heater element and non-heater element are entirely installed on same circuit board on existing electronic circuit board;Meanwhile, Fan exhaust is also arranged on circuit board, dust covering can be produced, electronic original part radiating can be reduced, dust produces electrostatic and can damage Other electronic original parts.Dust makes moist can cause short circuit, cause other electronics to damage, using with limitation.
The content of the invention
Prior art is difficult to meet the needs of people, in order to solve above-mentioned problem, the utility model proposes this Utility model proposes a kind of air-cooled circuit isolation structure, and isolation design prevents the infringement of high temperature and dust to product, extends electricity Sub- life of product, reduces repair rate.
For achieving the above object, the utility model provides following technical scheme:A kind of air-cooled circuit isolation structure, including PCB circuit main boards, fan Hot-air fan, heat-generating electronic elements, non-heat-generating electronic elements and thermal grease;The fan Hot-air fan passes through spiral shell Silk is fixedly connected on PCB circuit main boards front;The heat-generating electronic elements are welded on PCB circuit main boards front by BGA, and Heat-generating electronic elements are located at fan Hot-air fan lower section;Thermal grease is provided between the fan Hot-air fan and heat-generating electronic elements;Institute State non-heat-generating electronic elements and be arranged on the PCB circuit main boards back side, and non-heat-generating electronic elements by SMT welding and PCB circuit masters Plate is fixed.
Further, the non-heat-generating electronic elements are provided with several, and are distributed in the PCB circuit main boards back side.
Further, the PCB circuit main boards front is additionally provided with and is dielectrically separated from film.
Compared with prior art, the beneficial effects of the utility model are:The air-cooled circuit isolation structure, its employing will generate heat Electronic original part and non-heating electronic original part separate two sides and place so as to which the electronic original part that generates heat dissipates thermogenetic ash by radiator fan Dirt is without compromising on non-heating electronic original part;By isolating non-heat-generating electronic elements and heat-generating electronic elements, prevent high temperature to non- The damage of thermoelectric elements, improves the equipment speed of service.The gather dust because radiator fan radiates is reduced, dust makes moist short circuit, Damage to electronic original part and PCB main board, reduces equipment failure rate.It is practical, it is easy to promote the use of.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model;
In figure:1- fan Hot-air fans, 2- heat-generating electronic elements, 3-PCB circuit main boards, the non-heat-generating electronic elements of 4-, 5- radiatings Silica gel, 6- are dielectrically separated from film.
