The utility model provides a SVG processing system that generates heat, as shown in FIG. 1 and FIG. 2, this SVG processing system that generates heat includes: heat-conducting mechanism 1, cooling blower 2 and water-cooling circulating device. The heat absorption end of the heat conduction mechanism 1 is used for being in heat transfer connection with the interior of the SVG01 to absorb heat in the SVG01 and transfer the heat to the heat dissipation end of the heat conduction mechanism 1, the heat dissipation end of the heat conduction mechanism 1 is used for dissipating heat outside the SVG01, in addition, the heat conduction mechanism 1 is provided with a plurality of heat dissipation ends which are divided into two groups, one group is an air cooling heat exchange group, and the other group is a water cooling heat exchange group; the cooling fan 2 is used for blowing air to the heat dissipation ends of all the heat conduction mechanisms 1 in the air cooling heat exchange group, so that the heat dissipation effect is improved; the water-cooling circulating device is in heat transfer connection with the heat dissipation ends of all the heat conduction mechanisms 1 in the water-cooling heat exchange group, so that the heat of the heat dissipation ends of the heat conduction mechanisms 1 is absorbed through circulating water, and the effect of cooling the SVG01 is achieved; in addition, the circulating water for cooling the heat dissipation end of the heat conducting mechanism 1 can be reused.

It should be noted that the quantity ratio of the heat conducting mechanisms 1 in the air-cooling heat exchange group and the water-cooling heat exchange group is determined according to the actual conditions of the ambient air temperature, the circulating water quantity which needs to be reused and the like, but the SVG01 is ensured to be capable of normally operating for a long time.

It can be seen that the core of the SVG heating processing system has two: firstly, the heat dissipation area of the SVG01 is transferred to the outside of the SVG01 through the heat conduction mechanism 1, so that an air duct can be prevented from being arranged in the SVG01, the SVG01 can run in a relatively closed environment, the condition that dust is accumulated in the SVG01 is avoided, and the working state of the SVG is guaranteed to be hardly influenced by the environment where the SVG is located; secondly, improve the radiating effect through cooling blower 2 and water-cooling circulating device to avoid the inside amasss heat of SVG01, and then guarantee that SVG01 can run steadily for a long time, that is to say, this SVG processing system that generates heat makes SVG01 can lay in comparatively complicated or abominable environment, is favorable to building photovoltaic power plant in the great and sufficient area of light source of sand blown by the wind like this.

The following preferred exemplary embodiments are given here for the structural configuration of the heat-conducting means 1:

in the first embodiment, as shown in fig. 1 to fig. 3, the heat conducting mechanism 1 is specifically a heat conducting rod, that is, the heat conducting mechanism 1 is shaped like a rod, the heat conducting rod is vertically arranged on the top of the SVG01, in order to improve the heat transfer efficiency from the heat absorbing end to the heat dissipating end of the heat conducting rod, a cavity for storing a phase change medium is arranged inside the heat conducting rod, so that the phase change medium in the cavity is subjected to phase change gravity circulation between the heat absorbing end and the heat dissipating end, so as to rapidly conduct the heat in the SVG01 to the external environment and the water cooling circulation device.

It should be noted that, the interior of the cavity should be vacuumized to prevent the cavity from being heated and broken due to the air therein; the phase change medium is preferably a medium that can change phase at a relatively low temperature, such as water or alcohol.

In the second embodiment, in order to increase the heat dissipation rate of the heat dissipation end of the heat conduction rod, as shown in fig. 3, the heat dissipation end of the heat conduction rod is further provided with a plurality of heat dissipation fins 11, and the heat dissipation fins 11 can absorb the heat of the heat dissipation end of the heat conduction rod, wherein the plurality of heat dissipation fins 11 are sequentially arranged along the extending direction of the heat dissipation end of the heat conduction rod, so as to increase the heat dissipation effect of the heat conduction mechanism 1 by increasing the heat dissipation area.

The following preferred embodiments are given here for the structural configuration of the cooling fan 2:

in the third embodiment, as shown in fig. 2, the cooling blower 2 includes a blower body 21 and an air duct 22, wherein the blower body 21 is used for blowing air; the first end of the air pipe 22 is connected with the fan body 21, and the second end of the air pipe 22 is aligned with the heat dissipation ends of all the heat conduction mechanisms 1 in the air-cooled heat exchange group, so that air can be blown to all the heat dissipation ends of the heat conduction mechanisms 1; in addition, the second end of the air duct 22 is provided with a plurality of air outlets 221, and each air outlet 221 is aligned with the heat dissipation end of the heat conduction mechanism 1, so as to ensure that the air blast fully flows to the heat conduction mechanism 1, and further ensure the air cooling heat dissipation effect of the SVG 01.

In the fourth embodiment, based on the knowledge of heat transfer science, it can be understood that if the temperature difference between the heat source and the heat sink is larger, the heat transfer rate of the heat source and the heat sink is larger, and based on this idea: if the ambient temperature of the SVG01 is too low, the cooling fan 2 is not needed to be started, and the heat is directly exchanged with the external environment through the heat dissipation ends of all the heat conduction mechanisms 1 in the air-cooled heat exchange group, so that the air-cooled cooling effect of the SVG01 can be ensured; if the ambient temperature of the SVG01 is higher, the cooling fan 2 needs to be started to increase the heat dissipation rate of the heat dissipation end of the heat conduction mechanism 1, and the blowing amount of the cooling fan 2 should be increased as the ambient temperature is higher. The larger the "blowing amount" is, the higher the wind speed blown by the fan body 21 is.

Specifically, when natural air cooling of the external environment cannot effectively dissipate heat of the SVG01 through all the heat conducting mechanisms 1 of the air cooling heat exchange unit, for example, when the ambient temperature is high, if the temperature inside the SVG01 exceeds a preset switching temperature (for example, 20 ℃), the fan controller controls the cooling fan 2 to start, and if the internal temperature of the SVG01 still rises or is above a standard working temperature range, the fan controller gradually increases the power of the cooling fan 2 to increase the blowing amount, so as to ensure that no heat accumulation occurs inside the SVG01, and further ensure that the SVG01 can stably operate for a long time; if the internal temperature of the SVG01 is reduced, the fan controller gradually reduces the power of the cooling fan 2 to reduce the blast volume, so that the power consumption of the cooling fan 2 is saved under the condition of ensuring that the internal temperature of the SVG01 is within a standard working temperature range; when ambient temperature is lower and the inside temperature of SVG01 is less than preset switch temperature, also show that natural air-cooling can guarantee the cooling effect of SVG01, then cooling blower 2 is closed to fan controller.

It should be noted that, the structural structure and the functional principle of the first temperature detector and the fan controller can refer to the prior art, which is not described herein; the standard working temperature interval and the preset switch temperature corresponding to the control of the cooling fan 2 by the fan controller are determined according to actual factors such as the model of the SVG01, and the above 20 ℃ is only used as an example.

In addition, the determination factor of whether natural wind cooling can effectively perform wind cooling heat dissipation on the SVG01 includes but is not limited to the above-mentioned ambient temperature, and may also include factors such as the wind speed and humidity of the local environment, and accordingly, measuring instruments such as a wind speed tester and a humidity detector may also be added to further improve the condition factor of the fan controller for regulating and controlling the operation state of the cooling fan 2.
