Adopt the circuit board protector of technique scheme to have advantages of as follows: circuit board is in dielectric, and dielectric is arranged in the container of sealing, therefore circuit board and external environment are spaced, and can effectively prevent dust, protection against the tide, arc extinguishing antiknock, deepwater pressure resistant; In addition because dielectric carries out outer circulation by pipeline, and be provided with temperature-adjusting device on pipeline, therefore the heat that circuit board produces can distribute timely and effectively, psychro-environment can enter the thermophilic starting state fast, setting by temperature sensor and controller, can under different temperatures, start different circulation power and temperature-adjusting device, thereby guarantee good thermophilic effect, guarantee the steady operation of circuit board; Owing to adopting the liquid parcel, can realize the arrangement under water of circuit board in addition, make the interior external pressure of protective device basic identical, avoid the squeeze and destroy to circuit board.
As preferred version, in order to improve the electromagnetic protection effect of whole protective device, reduce external interference, described container can add aluminium film separator.
As limited scheme, in order to guarantee the effect of thermophilic, reduce costs simultaneously, described temperature-adjusting device is resistance heater, air cooler, water cooler, compression-type refrigerator, absorption chiller, steam-sprayed refrigerator, semiconductor cooler.
As preferred version, consider in electric equipment a circuit board may be arranged incessantly, in order to guarantee effective operation of total system, avoid interference each other simultaneously, improve protection effect, described container parallel connection or series connection are provided with at least two, and different circuit boards can be arranged in different containers.
As preferred version, consider that a plurality of temperature-adjusting devices can in parallel or series connection, in order to guarantee effective operation of total system, avoid interference each other simultaneously, improve protection effect, described container parallel connection or series connection are provided with at least two, and different circuit boards can be arranged on different liquid and flow back in road.
As preferred version, consider the convenience that controller is installed and control is used, described temperature sensor, cycle power device and temperature-adjusting device can be connected with controller by wired or wireless mode.Electric connection can be transmitted the signal of telecommunication of start and stop heatings or refrigeration, comprises signal, external remote control signal that the transducing signal in circulation fluid, protected circuit board send.
As preferred version, consider practicality and the economy of circulation power, limiting described circulation power is fluid pump, gas negative pressure fluid driver, gas positive pressure fluid driver.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention circulation fluid formula self-sensing thermophilic circuit board protector.
embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, the invention provides a kind of circulation fluid formula self-sensing thermophilic circuit board protector, include the sealing aluminium film container 2 of laying circuit board 1, the dielectric of the hot mediator of submergence circuit board 1 is housed in aluminium film container 2, be heat conductive insulating liquid, be provided with temperature sensor 4 in dielectric, the pipeline 5 of the sealing part sealed insulation liquid outer circulation of aluminium film container 2 and the cable of circuit board 1, the entrance point of pipeline 5 is provided with and connects fluid pump 6, the outer semiconductor cooling device 7 that arranges of pipeline 5, the heating end of semiconductor cooling device 7 arranges fan; Temperature sensor 4, fluid pump 6, semiconductor cooling device 7 and fan all are electrically connected with controller 3, and controller 3, usually used as the part setting of circuit board, also can arrange separately.
