Abstract
The utility model provides a photovoltaic inverter cabinet utilizing heat pipe self-cooling radiation. The inverter cabinet comprises a cabinet body. An inversion power assembly is arranged at the upper part inside the cabinet body. A capacitive bus unit, a grid-connection isolation transformer and a grid-connection switch are arranged below the inversion power assembly. The cabinet body of the inverter cabinet is provided with an air inlet at the upper part and an air outlet at the lower part. The inverter cabinet is characterized in that a heat radiation opening is disposed on the top of the cabinet body; a heat pipe radiator is located above the inversion power assembly; a radiation fin part of the heat pipe radiator protrudes out of the cabinet through the heat radiation opening on the top of the cabinet body; and a waterproof rain cover is fixedly arranged at the top of the protruded part of the heat pipe radiator. According to the utility model, fans are eliminated, so that the inverter cabinet is free from maintenance, and the cost is reduced; the heat pipe radiator is mounted on the top of the inverter cabinet, and the heat can be discharged to the external of the cabinet body based on the working principles of the heat pipe, thereby achieving self-cooling heat radiation with high speed and good effects; besides, a relatively high IP level inside the cabinet is kept.
Description
Technical field
The utility model belongs to field of photovoltaic power generation, relates to a kind of box Inverter Station structural design, is a kind of box Inverter Station structure that adopts heat pipe self-cold radiating mode to be dispelled the heat specifically.
Background technology
Inverter is a kind of power adjusting device be comprised of semiconductor device, is mainly used in direct current power is converted to alternating electromotive force.Generally by boost loop and inversion bridge type return, formed.The loop of boosting boosts to inverter output to the direct voltage of solar cell and controls required direct voltage; The inversion bridge type return the direct voltage after boosting of equal value convert the alternating voltage of conventional frequency to.General inverter is arranged to cabinet, various inverter assemblies are arranged in cabinet, then offer air inlet and air outlet on cabinet, wherein the pyrotoxin of inverter cabinet is the (PCC) power IGBT power device in cabinet, traditional inverter cabinet arrangement is as shown in Figure 1: the import at cabinet is provided with high-speed fan 2, heat sink assembly is arranged on high-speed fan, outdoor cold air is through the air inlet of the outer bottom of casing, delivered to the bottom of inverter cabinet by high-speed fan 2, force and send the inverter cabinet (PCC) power to, then from the air outlet on cabinet top, shed, air channel just need to be passed from cabinet like this, then heat is sent to the cabinet outside.The drawback of this kind of cabinet body structure design is that air channel needs tight the cooperation, and the upper strata (PCC) power is subject to the impact of lower floor's (PCC) power, and in same plane, the upper component temperature must be higher than the temperature of lower floor (PCC) power.Dust, from process in cabinet, can bring a large amount of dusts on the other hand, if cleaning not in time must impact components and parts in cabinet.
Summary of the invention
The utility model provides a kind of inverter cabinet that adopts heat pipe self-cold radiating mode to be dispelled the heat mainly for the deficiencies in the prior art, the radiator of this Inverter Station cabinet is arranged on top, adopt heat pipe radiator, can directly the heat in inverter cabinet be fallen apart outside the Inverter Station casing, reach self-cold radiating.
The technical scheme that the utility model provides: described a kind of heat pipe self-cold radiating formula photovoltaic inverter cabinet, comprise cabinet, be provided with the inverter power assembly above in cabinet, arranged beneath at the inverter power assembly has the electric capacity bus unit, grid-connected isolating transformer, grid-connected switch, offer air inlet below the inverter cabinet cabinet, top offers air outlet, it is characterized in that: at inverter cabinet cabinet top, offer thermovent, be provided with heat-pipe radiator above the inverter power assembly, the radiating fin part of heat-pipe radiator is stretched out cabinet from the thermovent at cabinet top, and be fixed with the waterproof rain cover at the top of heat-pipe radiator extension.
Described air outlet is provided with a plurality of, is opened in respectively the side on cabinet top.
The utility model has been cancelled blower fan, realize the non-maintaining purpose that reduces costs, heat-pipe radiator is installed, at the inverter cabinet top in the work of inverter cabinet internal power assembly, heat is discharged from the cabinet outside by the operation principle of heat pipe, thereby reach self-cold radiating, its rapid heat dissipation, good heat dissipation effect, in the process of extracting due to heat, do not exist the traditional heat-dissipating device to rely on the characteristics of blower fan air draft, therefore, can keep higher IP grade in cabinet; And the top of radiator is provided with and hides the rain waterproof cover, can't make the radiator be exposed be drenched bad by rainwater.
The accompanying drawing explanation
Fig. 1 is traditional photovoltaic inverter cabinet structural representation;
Fig. 2 is structural representation of the present utility model;
The schematic diagram that moves towards that Fig. 3 is the convection current of the utility model natural air.
In figure: 1-cabinet, 2-high-speed fan, 3-grid-connected isolating transformer, 4-electric capacity bus unit, 5-grid-connected switch, 6-inverter power assembly, 7-heat-pipe radiator, 8-waterproof rain cover, 9-air inlet, 10-air outlet.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model is clearly and completely described.As shown in Figure 2, described a kind of heat pipe self-cold radiating formula photovoltaic inverter cabinet, comprise cabinet 1, be provided with inverter power assembly 6 above in cabinet, arranged beneath at the inverter power assembly has electric capacity bus unit 4, grid-connected isolating transformer 3, grid-connected switch 5, offer air inlet 9 below inverter cabinet, top offers air outlet 10, it is characterized in that: at inverter cabinet cabinet 1 top, offer thermovent, be provided with heat-pipe radiator 7 above inverter power assembly 6, the radiating fin part of heat-pipe radiator 7 is stretched out cabinet 1 from the thermovent at cabinet top, and the top at heat-pipe radiator 7 extensions is fixed with waterproof rain cover 8.Described air outlet 10 is provided with a plurality of, is opened in respectively the side on cabinet 1 top.
The air inlet of described inverter cabinet is arranged in the position of cabinet bottom, when 6 free convections of cold air process inverter power assembly are discharged hot-air by air outlet.
In inverter cabinet, (PCC) power produces amount of heat (Fig. 3) when work, the heat-pipe radiator 7 of inverter power assembly 6 tops obtains these heats, working media by inside heat pipe, conduct to the top of heat pipe, heat pipe is by the function of its quick exchange heat, heat is passed to the radiating fin that exposes the inverter cabinet cabinet, by radiating fin, the heat of conduction is thrown away again, because cabinet belongs to a kind of open space outward, heat is directly discharged from top, cabinet is interior because the relation of negative pressure, the automatic air inlet 9 inspiration extraneous airs from the inverter cabinet bottom of meeting, form a kind of natural wind circulation, thereby reach heat pipe self-cold radiating mode.
