Description
Technical field
The utility model relates to inverter field, relates in particular to a kind of high-power inverter heat radiating system of whole machine.
Background technology
Inverter is that direct current energy (battery, accumulator jar) is transformed into alternating current (being generally 220V, 50Hz sine wave).It is made up of inverter bridge, control logic and filter circuit.Be widely used in air-conditioning, home theater, electric wheel, electric tool, sewing machine, DVD, VCD, computer, TV, washing machine, smoke exhaust ventilator, refrigerator, video tape recorder, massager, fan, illumination etc.Go out because the popularity rate of automobile is higher abroad work or out on tours is that available inverter connects storage battery and drives electrical equipment and various tool work.The vehicle-mounted inversion of exporting by cigar lighter is that 20W, 40W, 80W, 120W are to 150W power requirements.It is main that high-power inverter in the market dispels the heat to force air channel, radiating mode is mostly, equipment lower end air intake, the air port air draft that begins to rehearse of equipment top, utilize the air draft of top axle flow fan and machine cabinet door plate to form airtight air channel, this is designed with a very large drawback and is, lower end air intake is through after the heater elements such as reactor, gas flow temperature rises rapidly, and radiator air inlet is in complete machine middle part, the gas flow temperature sucking is higher, has caused reducing the radiating effect of radiator, and then allows and affect the inversion efficiency of whole set equipment.
Utility model content
The technical problems to be solved in the utility model is the higher radiating effect that weakened of gas flow temperature that existing high-power inverter radiator sucks, and affects inversion efficiency, and a kind of high-power inverter heat radiating system of whole machine is provided for this reason.
The technical solution of the utility model is: a kind of high-power inverter heat radiating system of whole machine, it comprises the air intake passage being extended to inverter top by inverter sidewall middle part, in described air intake passage, be surrounded by centrifugal blower, the end of described air intake passage is affixed with the gilled radiator that is positioned at centrifugal blower upside, described air intake passage has air inlet in inverter sidewall junction, described gilled radiator is in communication with the outside by some radiator air outlets at inverter top, the described air inlet that is positioned at centrifugal blower downside forms to 45 ° of close gradients of centrifugal blower, described inverter top also offers some complete machine air outlets, on described complete machine air outlet, be mounted with negative-pressure air fan.
Between air intake passage described in such scheme and centrifuge, be spaced apart 30-50mm.
The beneficial effects of the utility model are independently for gilled radiator designs heat dissipation channel, other internal structure isolation heat extraction with inverter, simultaneously by inversion unit circuit board and reactor isolation, reduce electromagnetism clear-cut, improve circuit stability, negative-pressure air fan can be avoided inverter top to drip and enter inverter inside, also drives air to flow out to complete machine air outlet from inverter bottom, reaches the separately object of heat radiation.
Brief description of the drawings

Fig. 2 is the vertical view of Fig. 1;
In figure, 1, air intake passage, 2, centrifugal blower, 3, gilled radiator, 4, air inlet, 5, radiator air outlet, 6, negative-pressure air fan.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, shown in Fig. 2, the utility model comprises the air intake passage 1 being extended to inverter top by inverter sidewall middle part, in described air intake passage, be surrounded by centrifugal blower 2, the end of described air intake passage is affixed with the gilled radiator 3 that is positioned at centrifugal blower upside, described air intake passage has air inlet 4 in inverter sidewall junction, the described air inlet that is positioned at centrifugal blower downside forms 45 ° of gradients that tilt to centrifugal blower, described gilled radiator is in communication with the outside by some radiator air outlets 5 at inverter top, described inverter top also offers some complete machine air outlets, on described complete machine air outlet, be mounted with negative-pressure air fan 6.
Air intake passage is airtight, it can be the hollow pipeline being spliced by heat-resisting sheet material or tubing, in hollow pipeline, be surrounded by centrifugal blower, the side that the air inlet of hollow pipeline is positioned at below centrifugal blower forms 45 ° of gradients that tilt to centrifugal blower, the benefit of this gradient is the supercharging air to introducing, accelerate the flowing velocity of air, improve radiating efficiency, the top of hollow pipeline and radiator bottom are affixed, the air that hollow pipeline is introduced enters gilled radiator through centrifugal blower booster and speed-increasing, discharge outside inverter by radiator air outlet again, this has just realized the independence heat radiation to spreader region.
In order better to maintain radiating effect, interval between air intake passage and centrifuge will be controlled well, if excessive radiating efficiency is low and to take inverter inner space more, if too small, the air capacity of introducing is few, Air Flow is also unfavorable for heat radiation slowly, preferably between air intake passage and centrifuge, be spaced apart 30-50mm, reach optimum efficiency.
On complete machine air outlet, be mounted with negative-pressure air fan 6 and be responsible for complete machine heat radiation, and prevent the upper end access arrangement that drips, effectively ensure electrical safety performance.
On described in the utility model, refer to the top that approaches high-power inverter, under refer to the bottom that approaches high-power inverter, the top of high-power inverter refers to one end that radiator air outlet and negative-pressure air fan are installed, and the bottom of high-power inverter refers to the other end away from radiator air outlet and negative-pressure air fan.
