Even if having occurred in that the scheme of large quantities of improvement heat dissipation for circuit board in the prior art, but still can not thoroughly it solve Certainly the problem of heat dissipation for circuit board.

The content of the invention

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides plug-in cooling circuit board, and it is not only wrapped The radiator structure layer on circuit substrate is included, radiator structure layer radiates from inside to circuit substrate, in addition, also in electricity The end of base board adds pluggable radiator structure, and the waste heat in heat dissipating layer is exported and radiated, and client can determine according to demand It is fixed whether the radiator structure of mounting end, cost is controllable, and radiating efficiency is high.

The technical scheme that the utility model is used is：Plug-in cooling circuit board, including circuit substrate and located at its bottom The radiator structure layer and membrane waterproofing in portion,

Radiator structure layer includes being filled with silica-gel desiccant between some copper pipes of abreast permutation, some copper pipes；

At least one end of each copper pipe extends beyond the end of circuit substrate；

Set copper pipe strengthens radiating part, the corresponding copper pipe enhancing radiating of circuit substrate beyond the end of circuit substrate as copper pipe The one end in portion is substrate radiating end, then pluggable U-shaped fin is cased with outside substrate radiating end, wherein also being sealed in U-shaped fin Equipped with cooling agent；

The copper pipe enhancing radiating part of U-shaped fin towards each copper pipe is accordingly provided with a radiating connecting hole；Copper The length of pipe radiating part is 3-15mm, and it inserts the inside of U-shaped fin.

Further, some grid-like radiating projections, each grid are provided with above at least one table of U-shaped fin Shape radiating projection is by glue sticking on the surface of U-shaped fin.

Further, some heat emission holes are provided with above at least one table of U-shaped fin.

Further, U-shaped fin is made up of aluminium.

Further, U-shaped fin is provided with least one hold-down mechanism, and each hold-down mechanism is connected to turnablely Thereon, it is pressed on when it is closed on circuit substrate.

Compared with prior art, the beneficial effects of the utility model are：Plug-in cooling circuit board of the present utility model, its In circuit substrate bottom increase radiator structure layer, heat dissipating layer is made up of the preferable copper pipe of thermal conduction characteristic, and each copper pipe it Between it is desiccant-filled, while by copper pipe extension circuit substrate, for connecting radiator structure, enhancing the thermal diffusivity of circuit substrate Can, rapid heat dissipation, surplus is not warm substantially for circuit, and service life is longer.

In addition, the radiator structure of the end of circuit substrate is pluggable, that is to say, that voluntarily can install and dismantle, will radiate Waste heat export radiating in layer, client can decide whether the radiator structure of mounting end according to demand, and cost is controllable, radiating efficiency It is high.
