Examples

The present embodiment provides a cooling device, as shown in fig. 1, which includes a cabinet 1, an air exhaust mechanism 2 and a cooling heat dissipation assembly.

The cabinet body 1 is suitable for covering the outside of the device to be cooled; the air exhaust mechanism 2 is arranged at the top of the cabinet body 1; the refrigeration heat dissipation assembly comprises a cooling water pipe 31 and a first air supply mechanism 32, a first depressed area is arranged on one side of the cabinet body 1, the cooling water pipe 31 is arranged in the first depressed area, and the first air supply mechanism 32 is arranged on the inner side of the cooling water pipe 31.

For example, when the cooling device is used to dissipate heat from the inverter 7, the cooling device is covered outside the inverter 7 and used as an inverter cabinet. After the inside temperature of cooling device risees, let in cold water in the condenser tube 31, start first air supply mechanism 32 and exhaust mechanism 2, outside air flows through condenser tube 31 cooling back, cold wind is sent into the cabinet body 1 inside through first air supply mechanism 32 again, cold wind mixes with the hot-blast of the internal portion of cabinet in order to reduce the inside temperature of device, the air after the cooling is discharged through the exhaust mechanism 2 at the cabinet body 1 top again and gets into electricity distribution room or outdoor, avoid hot-blast discharge to go into the electricity distribution room, guarantee that the electricity distribution room is in suitable temperature state, guarantee simultaneously that the electrical equipment of electricity distribution room inside is in normal temperature state in order to guarantee its normal use.

Alternatively, the air exhausting mechanism 2 is an exhaust fan, and the first air blowing mechanism 32 is an air blower. The cooling device further comprises an exhaust duct 4, and the exhaust duct 4 is arranged at the top of the cabinet body 1 and is communicated with an air outlet of the exhaust fan. Preferably, the exhaust duct 4 extends horizontally with its outlet extending outside the electrical distribution room to exhaust the air within the cabinet out of the electrical distribution room.

Referring to fig. 1, the cooling and heat dissipating assembly further includes a water blocking orifice plate 33, a first ventilation plate 34, a first flow guide plate 35, a first filter screen 36, and a second ventilation plate. The water blocking orifice plate 33 is disposed inside the first air blowing mechanism 32, the first ventilation plate 34 is disposed between the first air blowing mechanism 32 and the water blocking orifice plate 33, and the second ventilation plate is disposed between the cooling water pipe 31 and the first air blowing mechanism 32 to separate the cooling water pipe 31 from the first air blowing mechanism 32. For example, the first ventilation board 34 and the second ventilation board are both isolated louver type ventilation tilted boards, which do not affect the external air entering the cabinet 1.

The both ends of manger plate orifice plate 33 are pegged graft on the slot of the cabinet body 1 lateral wall, and outside air probably produces the condensate water droplet after the cooling of condenser pipe 31, and the condensate water droplet blocks through manger plate orifice plate 33 and can't get into inside the cabinet body 1, prevents that steam from getting into the inside normal use that influences the inside electrical equipment of the cabinet body 1 of cabinet body. The first ventilation board 34 is arranged on the windward side of the water retaining pore board 33, and plays a role of reducing the wind speed, so that the cold air mixed with condensed water drops can reach the water retaining pore board 33 at a slow speed, and the water drops can fall freely under the action of self weight. The water retaining pore plate 33 is a wind shielding porous mesh plate.

Preferably, the first recessed area is located at the bottom of the cabinet 1, so that cool air can enter from the bottom of the cabinet 1 to be sufficiently mixed with hot air at the bottom of the cabinet 1. The curb plate slope setting of the relative cabinet body 1 of first ventilating board 34 is equipped with a plurality of first guide plates 35 on the inboard cabinet body 1 inner wall of first depressed area, and a plurality of first guide plates 35 are arranged along the horizontal and vertical even interval of the internal wall of cabinet 1, guarantee that the cold air evenly gets into the cabinet body 1 inside. The outside cabinet body 1 of first depressed area is equipped with first air intake, and first air intake dustcoat is equipped with first filter screen 36, filters the dust impurity in the outside air, avoids impurity to get into the inside operational environment who pollutes converter 7 of the cabinet body 1.

The bottom of the first ventilating board 34 is provided with a water discharging pipe 6, and the water outlet of the water discharging pipe 6 extends to the outside of the cabinet body 1. The first ventilating plate 34 and the water retaining hole plate 33 are both arranged downwards and downwards towards one side of the drain pipe 6, so that condensed water drops gradually slide downwards along the surface of the condensed water drops to enter the drain pipe 6 and then are discharged out of the cooling device through the drain pipe 6.

Preferably, the other side of the cabinet body 1 is provided with a second recessed area, and the first recessed area is opposite to the second recessed area, for example, the first recessed area is located at the front side of the cabinet body 1, and the second recessed area is located at the rear side of the cabinet body 1. A second air supply mechanism 51 is disposed in the second recessed area, for example, the second air supply mechanism 51 is a fan. And a second air inlet is formed in the cabinet body 1 outside the second depressed area, and a second filter screen 52 is arranged outside the second air inlet and used for filtering impurity and dust in the air. The second sunken area is positioned at the bottom of the cabinet body 1 to ensure that normal temperature air enters from the bottom of the cabinet body 1 and is fully mixed with hot air in the cabinet.

The inner wall of the cabinet body 1 on the inner side of the second depressed area is provided with a plurality of second guide plates 53, and the plurality of second guide plates 53 are arranged along the horizontal and vertical uniform intervals of the inner wall of the cabinet body 1, so that the external air is ensured to uniformly enter the cabinet body 1.

The cooling water pipe 31 is provided with a flow electric control valve which can control the flow of cooling water entering the cooling water pipe 31 according to the temperature inside the cabinet and control the temperature of cold air entering the cabinet body 1.

Be equipped with on the cabinet body 1 and control panel 8, the cabinet body 1 is inside to be equipped with temperature sensor, and cooling device can set up interlocking start-up mode according to the counter temperature that temperature sensor surveyed. For example, when the frequency converter 7 is powered on or the temperature in the cabinet is lower than the lower limit mode of the temperature control value, the first starting mode is that the exhaust fan on the top of the cabinet runs; when the frequency converter 7 is electrified to operate and the temperature in the cabinet is lower than the high I value for alarming, the second starting mode is that the exhaust fan at the top of the cabinet and the air supply fan at the rear side of the cabinet body 1 operate; when the frequency converter 7 is powered on to operate and the temperature in the cabinet is ultrahigh, namely the value I is used for alarming but is lower than the value II, the starting mode III is that the cabinet top exhaust fan, the cabinet rear air supply fan and the cabinet front air supply fan operate simultaneously; when the frequency conversion cabinet is electrified to operate and the temperature in the cabinet is ultrahigh, and the II value alarms, the starting mode is four, namely the cabinet top exhaust fan, the cabinet rear air supply fan and the cabinet front air supply fan operate simultaneously, and cooling water is introduced into the cooling water pipe 31. Effectively adjust the interior temperature of cabinet, prevent that 7 temperature risees of converter from leading to damaging, but 7 long-term operation of converter reduce 7 fault rates.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
