Technical field
This utility model relates to a kind of heat sink, is specifically related to a kind of heat sink being applied to Active Power Filter-APF.
Background technology
Active Power Filter-APF (Active
Power Filter, it is called for short APF) it is the new electric energy quality control apparatus of a kind of electrically-based electronic technology and modern control theory, it is the new electric energy quality control apparatus of a kind of device for harmonic and idle problem, is the effective means of comprehensive control electric network pollution, has broad application prospects.Harmonic wave that frequency and amplitude can all be changed by it and idle carry out continuous dynamic compensation, has high controllability and fast-response, and its compensation characteristic is much better than passive filter.In theory, the storage capacitor capacity needed for being not required to energy storage unit, device during compensating power is the least.Having the ability of the change of Tracking Frequency of Power Grids, compensation performance is not changed by mains frequency to be affected.Affected little by electric network impedance, it is not easy to and electric network impedance generation resonance.When line voltage reduces, compensation capacity does not reduces；When required compensation electric current exceedes design capacity, also will not transship, and can normally play compensating action.
And current electric-power filter is usually body structure, its casing is outer container, internally installed have electric-power filter, electric-power filter is in use, elimination along with harmonic wave, substantial amounts of heat can be produced, but too much heat build-up, device failure can be caused, equipment cannot be properly functioning, it is all to be dispelled the heat by multiple air intakes fan and multiple exhaust fan in existing, this carry out radiating and cooling by fan, can manage it in spring and autumn effect, in summer, the outer temperature of casing is too high, only dispelled the heat by fan, not reach expected effect, and multiple fan rotates and also needs to additionally consume more electric energy, add operating cost, therefore, it is necessary to research and develop device that is a kind of the most energy-conservation but also that can effectively reduce case body temperature.
Summary of the invention
According to the deficiencies in the prior art, a kind of radiating efficiency that can improve electric-power filter is provided, and the uniformity of heat radiation can be improved, and then it is easy to improve the uniformity of Active Power Filter-APF heat radiation, thus the Active Power Filter-APF heat sink in the service life of Active Power Filter-APF can be improved.
This utility model is realized by techniques below scheme:
A kind of heat sink being applied to Active Power Filter-APF, include active power filter body and for containing and the heat sink of radiation active electric-power filter body, this heat sink includes that cross section is circular, the casing of hollow, casing is divided into upper chamber and two spaces of lower chambers by a horizontal plate by described box house, multiple air vent is had on described horizontal plate, described Active Power Filter-APF body is arranged on horizontal plate, the bottom surface of described casing is provided with multiple air intake fan, and the side surface upper part of described casing is provided with multiple exhaust fan；The flat board that the side of described casing is arranged by two block gaps forms, and is filled with phase-change material between two pieces of flat boards；Also include one for the temperature monitor monitoring casing internal and external temperature.
Preferably, the outer of the top cover of described casing is provided with the bending plate for rain cover, and described bending plate tilts obliquely.
Preferably, the bottom surface of described casing is also equipped with multiple universal wheel.
Preferably, described phase-change material uses the phase-change material of 32 ° of C.
This utility model beneficial effect:
This utility model uses phase-change material, phase-change material refers to vary with temperature and change state of matter and be provided that the material of latent heat, the process changing physical property is referred to as phase transition process, at this moment phase-change material by absorption or discharges substantial amounts of latent heat, by maintaining the Active Power Filter-APF life-span in a certain specific temperature, this temperature beneficially casing of the temperature in casing to be extended with fan and temperature monitor.

Fig. 2 is according to the heat sink side view of Active Power Filter-APF in embodiment illustrated in fig. 1；
Fig. 3 is according to the housing schematic bottom view in the heat sink of Active Power Filter-APF in embodiment illustrated in fig. 1；
In figure: 1 Active Power Filter-APF body, 2 casings, 2-1 upper chamber, 2-2 lower chambers, 2-3 flat board, 3 horizontal plates, 4 air vents, 5 air intake fans, 6 exhaust fan, 7 phase-change materials, 8 temperature monitors, 9 bending plates, 10 universal wheels.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, this utility model is further described.
Embodiment one:
A kind of heat sink being applied to Active Power Filter-APF, include active power filter body 1 and for containing and the heat sink of radiation active electric-power filter body 1, this heat sink includes that cross section is circular, the casing 2 of hollow, casing 2 is internal is divided into upper chamber 2-1 and two spaces of lower chambers 2-2 by a horizontal plate 3 by casing 2, multiple air vent 4 is had on horizontal plate 3, Active Power Filter-APF body 1 is arranged on horizontal plate 3, the bottom surface of casing 2 is provided with multiple air intake fan 5, and the side surface upper part of casing 2 is provided with multiple exhaust fan 6；The flat board 2-3 that the side of casing 2 is arranged by two block gaps forms, and is filled with phase-change material 7 between two pieces of flat board 2-3, and phase-change material 7 uses the phase-change material of 32 ° of C, has the advantages that latent heat is big and stability is high, and the use cycle is more than 20 years；Also include one for the temperature monitor 8 monitoring casing 2 internal and external temperature, the outer of the top cover of casing 2 is provided with the bending plate 9 for rain cover, bending plate 9 tilts obliquely, can prevent rainwater on rainy day from entering wave filter to a certain extent, and the bottom surface of casing 2 is also equipped with multiple universal wheel 10.
Use process, when temperature monitor 8 monitor casing 2 external environment temperature less than phase transition temperature and casing 2 in temperature higher than equipment assigned temperature time, air outside casing 2 can be inputted in casing 2 by air intake fan 5, on the one hand freezes for casing 2, on the other hand stores energy in phase-change material 7；When temperature monitor 8 monitor casing 2 external environment temperature higher than phase transition temperature or casing 2 in temperature less than a certain assigned temperature time, air intake fans 5 systems and can quit work, the cold energy that release has stored, reaches the purpose of refrigeration.During this, only consume fraction of electric energy (fan power consumption), but the temperature that can solve Active Power Filter-APF well controls a difficult problem.
