Abstract
The utility model discloses a cooling heat sink for frequency converter, comprising an air cooler (1) and a fan (2) disposed above the air cooler (1); the air cooler (1) is provided with a water inlet (1.1) and a water outlet (1.2); the water outlet (1.2) is disposed under the water inlet (1.1). When using the utility mode, the frequency converter can be disposed under the air cooler; because the air cooler is provided, the hot wind from the fan can exchange heat by the air cooler, so that the hot wind becomes the cold wind, so as to cool the frequency converter and increase the heat dissipation; good cooling effect is realized when low energy consumption is ensured simultaneously.
Description
Technical field
The utility model relates to the frequency converter field, owing to relate to a kind of high-power high voltage frequency converter, specifically is meant a kind of frequency converter cooling heat radiator.
Background technology
The requirement of the operating ambient temperature of high voltage converter is usually at 0 ℃～40 ℃, because frequency converter can distribute heat when operation, thereby causes the ambient temperature of operation of frequency converter too high and make the frequency converter overtemperature protection and trip easily.Particularly during the broiling summer because the higher heat that produces in the frequency converter self-operating process of adding of ambient temperature, through regular meeting overtemperature protection takes place and the thing that trips takes place, when serious even cisco unity malfunction, had a strong impact on normally carrying out of producing.
For addressing the above problem, existing solution generally is that frequency converter is placed in the air-conditioned room, utilizes air-conditioning to reduce the temperature of environment, thereby makes the ambient temperature of frequency converter operation reach requirement.But this mode owing to be that the entire environment temperature is lowered the temperature, must be used the air-conditioning of big refrigerating capacity if room space is big, energy consumption is bigger, and owing to is whole room to be lowered the temperature also caused the unnecessary waste of refrigerating capacity.
Also has a kind of frequency converter cooling system in addition; Then be that frequency converter is placed below the blower fan, thereby the flowability of utilizing blower fan to increase air is accelerated the inner heat radiation of frequency converter, though this mode energy consumption is lower; But because blower fan itself does not have refrigerating function; If temperature is high, though air flow is accelerated, the ambient temperature especially ambient temperature of frequency converter operation is still fallen not little next.
The utility model content
The technical problem that the utility model will solve is to the existing in prior technology weak point, provides that a kind of energy consumption is lower, cooling effect frequency converter cooling heat radiator preferably.
The technical solution of the utility model is, following a kind of frequency converter cooling heat radiator is provided, and comprises air cooler and the blower fan that is located at the air cooler top, and described air cooler is provided with water inlet and delivery port, described delivery port be located at water inlet below.
After adopting above scheme; The utility model frequency converter cooling heat radiator; In use can with frequency converter place air cooler below; Owing to increased air cooler, blower fan is blown over the hot blast that comes and can be carried out heat exchange through air cooler and hot blast is become cold wind frequency converter is cooled off increase heat radiation then, is guaranteeing that energy consumption has also played favorable cooling effect in lower.
As preferably, described water inlet and delivery port are located at the two ends up and down of air cooler respectively.
Above-mentioned optimal way is located at the two ends up and down of air cooler respectively with water inlet and delivery port, and so in use, hot blast can be cooled off through the air device step by step, and cooling effect is better.
Description of drawings
It in the accompanying drawing the utility model frequency converter cooling heat radiator overall structure sketch map.
Shown in the figure:
1, air cooler, 1.1, water inlet, 1.2, delivery port, 2, blower fan.
Embodiment
For ease of explanation,, the frequency converter cooling heat radiator of utility model is elaborated below in conjunction with accompanying drawing:
Shown in accompanying drawing; A kind of frequency converter cooling heat radiator; Comprise air cooler 1 and the blower fan 2 that is located at air cooler 1 top, described air cooler 1 is provided with water inlet 1.1 and delivery port 1.2, and described water inlet 1.1 and delivery port 1.2 are located at the two ends up and down of air cooler 1 respectively.
In the above-described embodiments, the preferred forms of the utility model is described, obviously; Under the inventive concept of the utility model, still can make a lot of variations, substitute like air cooler 1 also free list cooler; In use; Frequency converter also can place in the airtight frequency converter cabinet and above that the lower end hot-blast outlet and cold wind import are set respectively, the hot blast import is connected with the inlet scoop of blower fan, the cold wind import is connected with the air outlet of air cooler.At this, should explain that any change of under the inventive concept of the utility model, being made all will fall in the protection range of the utility model.
