Detailed description of the invention
Technical scheme and the technique effect reached for making to present invention solves the technical problem that, using are clearer, below
Technical scheme is further illustrated in conjunction with accompanying drawing and by detailed description of the invention.
Embodiment 1
As Figure 1-4, as a example by Fig. 3, the left and right directions in figure is left and right directions, and above-below direction is fore-and-aft direction.This
Embodiment provides a kind of DC/DC changer, including flat surface transformer, macromolecule solid capacitor and shell 1, the inner chamber 2 of shell 1
In be provided with for accommodating flat surface transformer and the receiving portion of macromolecule solid capacitor, the top of shell 1 is provided with along right and left
To arrange multiple first radiating fins 3, the first radiating fin 3 be arranged above radiator fan 4.Use plane transformation
Device, it is to avoid the hidden danger of turn-to-turn open circuit, uses macromolecular solid body capacitance, improves resistance to elevated temperatures, by radiator fan 4 and the
One radiating fin 3, improves heat dispersion 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 dispersion of shell 1 so that electronics in inner chamber 2 unit
The heat of part can shift in time, it is to avoid in inner chamber 2, temperature raises too big, causes fault.
As shown in Figure 4, the first radiating fin 3 width from bottom to top gradually decreases, and forms the structure that bottom width top is narrow.
As in figure 2 it is shown, the front side of shell 1 and rear side are vertically installed with the second radiating fin 5, the bottom of the second radiating fin 5 is to top
Width gradually decrease, form the narrow structure in bottom width top.The highest at the regional temperature of the outer surface near shell, bottom is wider
First radiating fin 3 and the second radiating fin 5 expand and the contact area of shell 1, accelerate heat and shift first from shell 1
Radiating fin 3 and the speed of the second radiating fin 5.The top of the first radiating fin 3 and the second radiating fin 5 is narrower, both saves
Material, expands again the distance between each first radiating fin 3, between each second radiating fin 5, it is simple to air-flow leads to
Crossing, accelerate heat and distribute, simultaneously the temperature in region at top is less than bottom, and surface with shell 1 does not contacts, the most not
The heat affecting shell 1 is transferred on the first radiating fin 3 and the second radiating fin 5.
The top of the inner chamber 2 of shell 1 is provided with temperature sensor, temperature sensor electrical connection controller, controller according to
The signal of temperature sensor controls radiator fan 4 and rotates.When the temperature in temperature sensor detects inner chamber 2 raises, control
Device controls being stepped up of radiator fan 4, to accelerate the air circulation between the first radiating fin 3, accelerates heat radiation.
Forming heat radiation air flue between the first adjacent radiating fin 3, radiating tube can be laid in the bottom of heat radiation air flue, heat radiation
Pipe is provided with coolant.Coolant can be cooling water or other working fluid.Radiating tube is laid on the table of shell 1
Face, can strengthen the heat radiation of shell 1 further, and heat radiation air flue itself end of in the structure of narrow top width, radiating tube is arranged on heat radiation
The bottom of air flue, has no effect on the airflow of the middle and upper part of heat radiation air flue, and the heat radiation on the first radiating fin 3 affects little,
Radiating tube and the combination of the first radiating fin 3, greatly improve the heat dispersion of shell 1.
The two ends of radiating tube are connected to input hole and the delivery outlet of outside heat sink, outside heat sink are evenly equipped with many
Individual the 3rd parallel radiating fin, is provided with driving pump between input hole and delivery outlet.By outside heat sink, by radiating tube
The heat of the higher coolant of temperature distribute, become the coolant that temperature is relatively low, continue cycling through use.3rd radiating fin
The middle part of sheet forms the Cooling Holes for the coolant that circulates, the Cooling Holes of the afterbody of each 3rd radiating fin and the next 3rd
Between the Cooling Holes of the head of radiating fin by heat radiation manifold connect, the Cooling Holes of the head of first the 3rd radiating fin with
Input hole connects, and the Cooling Holes of the afterbody of last the 3rd radiating fin connects with delivery outlet, drives pump near delivery outlet.Drive
Dynamic pump is for driving the flowing of coolant, and drives pump near delivery outlet, and the temperature of coolant is relatively low, it is to avoid long-time use is right
Driving pump to produce impact, whole 3rd radiating fin communicates with each other and forms one article of sinuous radiator structure, greatly increases cold
But the length of the heat dissipation region of agent, and in the middle part of the 3rd radiating fin, directly form Cooling Holes, coolant directly passes through Cooling Holes
Outer wall heat radiation, accelerate radiating rate, and do not affect the air flue between the 3rd radiating fin, it is simple to air circulate.3rd dissipates
The top of hot fin is additionally provided with external cooling fan, further speeds up the air circulation between the 3rd radiating fin, accelerates to dissipate
Heat.
Controller is also electrically connected with alarm device, and when the detected value of temperature sensor exceedes setting value, controller controls
Alarm device is reported to the police, and reminds the temperature in staff's inner chamber 2 too high, it is to avoid fault occurs.The side of shell 1 also sets up
There is input port 6, control port 7 and two output ports 8, multiple voltage can be exported, and by controlling port 7 controlling party
Just.
Above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention's
Thought, the most all will change, and this specification content should not be construed as the present invention
Restriction.
