Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
In conjunction with attached drawing and pass through specific embodiment to further illustrate the technical scheme of the present invention.
Embodiment 1
As shown in Figs 1-4, by taking Fig. 3 as an example, the left and right directions in figure is left and right directions, and up and down direction is front-rear direction.This
Embodiment provides a kind of DC/DC converter, including flat surface transformer, macromolecule solid capacitor and shell 1, the inner cavity 2 of shell 1
In be provided with receiving portion for accommodating flat surface transformer and macromolecule solid capacitor, the top of shell 1 is provided with along right and left
To multiple first radiating fins 3 of arrangement, the top of the first radiating fin 3 is additionally provided with radiator fan 4.Using plane transformation
Device avoids the hidden danger of turn-to-turn open circuit, using macromolecular solid body capacitance, improves high temperature resistance, passes through radiator fan 4 and
One radiating fin 3, improves heat dissipation performance and stability.When radiator fan 4 operates, air-flow is from the first adjacent radiating fin 3
Between flow through, take away the heat on the first radiating fin 3, improve the heat dissipation performance of shell 1 so that in inner cavity 2 electronics member
The heat of part can shift in time, avoid in inner cavity 2 temperature from increasing too big, cause fault.
As shown in figure 4, the width of the first radiating fin 3 from bottom to top gradually decreases, the narrow structure in bottom width top is formed.
As shown in Fig. 2, the front side of shell 1 and rear side are vertically installed with the second radiating fin 5, the bottom to top of the second radiating fin 5
Width gradually decrease, form the narrow structure in bottom width top.Regional temperature highest in the outer surface close to shell, bottom are wider
First radiating fin 3 and the second radiating fin 5 expand the contact area with shell 1, accelerate heat from the transfer of shell 1 first
The speed of radiating fin 3 and the second radiating fin 5.The top of first radiating fin 3 and the second radiating fin 5 is relatively narrow, both saves
Material, and expand between each first radiating fin 3, the distance between each second radiating fin 5, it is logical convenient for air-flow
It crosses, accelerates heat and distribute, while being lower than bottom in the temperature in the region at top, and do not contact with the surface of shell 1, therefore not
The heat for influencing shell 1 is transferred on the first radiating fin 3 and the second radiating fin 5.
The top of the inner cavity 2 of shell 1 is provided with temperature sensor, and temperature sensor is electrically connected controller, controller according to
The signal control radiator fan 4 of temperature sensor rotates.When temperature sensor detects that the temperature in inner cavity 2 increases, control
Device control radiator fan 4 is stepped up, and to accelerate the air circulation between the first radiating fin 3, accelerates heat dissipation.
Heat dissipation air flue is formed between the first adjacent radiating fin 3, the bottom for the air flue that radiates can be laid with heat-dissipating pipe, radiate
Coolant is provided in pipe.Coolant can be cooling water or other working fluids.Heat-dissipating pipe is laid on the table of shell 1
Face can further strengthen the heat dissipation of shell 1, and the air flue itself that radiates is in the wide structure of bottom narrow top, and heat-dissipating pipe setting is being radiated
The bottom of air flue has no effect on the airflow of the middle and upper part of heat dissipation air flue, influences less on the heat dissipation of the first radiating fin 3,
The combination of heat-dissipating pipe and the first radiating fin 3, greatly improves the heat dissipation performance of shell 1.
The both ends of heat-dissipating pipe are connected to the input hole and delivery outlet of outside heat sink, and external cooling on piece is evenly equipped with more
A parallel third radiating fin, is provided with transfer tube between input hole and delivery outlet.It, will be in heat-dissipating pipe by outside heat sink
The heat of the higher coolant of temperature distribute, become the lower coolant of temperature, continue cycling through use.Third radiating fin
The middle part of piece forms the cooling hole for the coolant that circulates, the cooling hole of the tail portion of each third radiating fin and next third
Between the cooling hole on the head of radiating fin by heat dissipation manifold connection, the cooling hole on the head of first third radiating fin with
Input hole connection, the cooling hole of the tail portion of the last one third radiating fin are connected to delivery outlet, and transfer tube is close to delivery outlet.It drives
The dynamic flowing pumped for driving coolant, and transfer tube, close to delivery outlet, the temperature of coolant is lower, avoids use pair for a long time
Transfer tube has an impact, and entire third radiating fin communicates with each other to form a sinuous radiator structure, greatly increases cold
But the length of the heat dissipation region of agent, and cooling hole is directly formed in the middle part of third radiating fin, coolant directly passes through cooling hole
Outer wall heat dissipation, accelerate radiating rate, and do not influence the air flue between third radiating fin, be convenient for air circulation.Third dissipates
It is additionally provided with external cooling fan at the top of hot fin, further speeds up the air circulation between third radiating fin, accelerates to dissipate
Heat.
Controller is also electrically connected with warning device, when the detected value of temperature sensor is more than setting value, controller control
Warning device alarm, reminds the temperature in staff inner cavity 2 excessively high, avoids that fault occurs.The side of shell 1 is also set up
There are input port 6, control port 7 and two output ports 8, multiple voltage can be exported, and pass through 7 controlling party of control port
Just.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
