Abstract
The utility model relates to a 'natural cooling and auxiliary air cooling automatic change-over heat exchange device', belonging to the power electronic equipment ventilation and heat dissipation structural matching filed. Particularly, aiming to solve the problems of a high-power self-cooling heat-dissipation rectifier such as disadapted structural conditions of a backup auxiliary air cooling heat-dissipation mode, the utility model provides an automatic change-over heat exchange device (as shown in an attached drawing) so as to meet the requirements of two heat-dissipation condition. The automatic change-over heat exchange device adopts the following structure that: firstly, the upper part of a front door of a cabinet body is provided with holes so as to install a louver, thereby opening an exchange channel between the inside of a rectifier and the outside environment; three auxiliary fans are arranged forwards at an upper part inside a cabinet, and are slightly separated from a front air outlet; therefore, a naturally ascending heat flow can be smoothly discharged from the front air outlet so as to ensure the heat-dissipation efficiency of a natural cooling main mode; when an auxiliary fan (9) is started to assist heat dissipation, forward air pressure automatically closes an upper air deflector (5) and a lower air deflector (6), thereby forming an outlet air channel and realizing forced discharge of heat inside the cabinet; moreover, the multifunctional heat-dissipation device realizes double heat dissipation of natural cooling and auxiliary air cooling, and is capable of automatic change over.
Description
Technical field
The utility model is applicable in the heavy-duty rectifier of dual heat radiation, solves natural cooling and auxiliary air cooling and extraneous overall situation and directly exchanges heat radiation, improves the problem of radiating efficiency.
Background technology
In common heavy-duty rectifier, the radiating modes that adopt forced air cooling more, belong to and forcing and wind-cooling heat dissipating mode initiatively, rectifier provides lasting air quantity to guarantee heat radiation by the blower fan of fixing air channel and big flow, the dependence of bringing thus to blower fan system is strong, reliability requirement is higher, in case the blowing-out rectifier can not move; Very big heat radiation air quantity makes the dust accumulation in the rectifier serious simultaneously, even can cause the fault of rectifier; The air-cooled mode that changes self-cold radiating into of Shi Hanging for this reason, just formed complete passive radiating mode, only solved the problem that reduces wind flow, reduces the collection ash, but can not solve with extraneous overall situation and exchange heat radiation and seasonality or the special operation condition problem of heat radiation down, cause equipment operation temperature high cooling efficiency low, worsen running environment, influenced rectifier normal output and security reliability.
Summary of the invention
At heavy-duty rectifier radiating mode, radiator structure and the problem that exists with aspect such as environmental condition incompatibility, the utility model proposes the heat-exchanger rig of a kind of natural cooling and auxiliary air-cooled automatic conversion, based on the natural cooling heat radiation, again under the dual radiating mode of auxiliary wind-cooling heat dissipating, utilize the structure of a forward direction water conservancy diversion, the hot-fluid that a part can be risen is derived by the air port, Qianmen, realize direct exchange heat radiation with overall situation, reduce the heat accumulation in the rectifier chamber, thereby improved the radiating efficiency of natural cooling.To open auxiliary air-cooled effect in order taking into account simultaneously, on this structure, to install three auxiliary blowers forward, and be provided with the wind deflector that automatic interlock is closed, cooperate the operation of fan, guarantee maximum heat exchange efficiency with extraneous overall situation.
The technical solution adopted in the utility model is: the incompatible problem of environmental condition that conventional traditional radiator structure of heavy-duty rectifier and rectifier are moved, demand and condition according to reality, do not rely on and the change of overcritical external condition, but from the radiating mode and the structure of rectifier unit self, make full use of the favorable factor of field environmental condition, make the best use of the situation and only make some special design and structural arrangements improved, natural cooling and auxiliary air-cooled combining have just been realized, direct and extraneous overall situation convective exchange, high efficiency, high-adaptability, multi-functional heat abstractor.
The beneficial effects of the utility model are: the integral heat sink ability to heavy-duty rectifier has remarkable lifting, the element temperature rise reduces by ten remainings under the equal conditions, its heat dispersion has improved an order of magnitude, temperature control and reliability that dual radiator structure has been guaranteed power electronic device have realized high efficiency, high performance multifunctional heat dissipation mode.
Description of drawings
Accompanying drawing is structural representation of the present utility model, and Fig. 1 establishes at rectifier cubicle (2) and rectification for the utility model Standby indoor (1), frame of broken lines (3) among the residing rigging position figure, and (4) are the factory building overall situation, set up straight Connect the convective exchange with overall situation, solve exactly the key of rectifier heat dissipation problem. Fig. 2 is tool of the present utility model The body assembly structure figure, (7) top, Qianmen nature air outlet blind window wherein, (8) auxiliary blower mounting bracket and Wind scooper, three of (9) auxiliary blowers, (5) (6) free convection wind deflector, autoshutdown during starting fan.
Embodiment
Because the utility model is to utilize the convection of heat principle, opens up air outlet forward on rectifier cubicle top, and forms local forward direction pressure reduction, help heat and discharge naturally, and based on self-cold radiating.Three auxiliary blowers are installed on wind scooper and dry forward, the automatic interlock in fan starting back is closed wind deflector up and down when needing, form wind-cooling heat dissipating passage efficiently, discharge in the rectifier cubicle as early as possible and the heat of indoor gathering, fan need only the short-term intermittent duty, use as the reserve of special operating mode is emergent, heat-exchanger rig of the present invention can satisfy the automatic conversion and the heat-sinking capability of two kinds of radiating modes.
Claims (1)
1. the utility model " heat-exchanger rig of a kind of natural cooling and auxiliary air-cooled automatic conversion ", be to be assemblied in power rectifier cabinet top, take into account natural cooling and auxiliary air-cooled two kinds of radiating modes, and the heat exchange structure with auto-conversion function designs, it is characterized in that: shutter is established in the top perforate at the cabinet Qianmen, got through the interchange channel between rectifier inside and the extraneous overall situation, three auxiliary blowers utilize wind scooper to make mounting bracket, be installed in and leave any position of air outlet slightly, guarantee that the hot-fluid that nature rises discharges from front air outlet smoothly, when opening the auxiliary blower operation, the automatic interlock of forward direction blast is closed wind deflector up and down, form wind-cooling heat dissipating passage efficiently, realized natural cooling and auxiliary air-cooled dual radiating mode, and the multifunctional heat dissipation device that can change automatically.
