Abstract
The utility model relates to an anti-dew formation water cooling device for a mine explosion-proof frequency converter. A cooling water channel is formed inside a water cooling plate of the anti-dew formation water cooling device; water inlets positioned on the lower part of the water cooling plate and a water outlet positioned on the upper part of the water cooling plate are formed on the cooling water channel; and a water inlet is formed in the middle of the water cooling plate. A water channel cooling cycle is adopted; in order to avoid the dew formation phenomenon when the upper and lower parts of the water cooling plate are provided with heating power devices, a mode that the middle water inlet is blocked and water enters the lower water inlet and flows out of the upper water outlet is adopted; and in order to avoid the dew formation phenomenon when only the upper part of the water cooling plate is provided with a heating power device, a mode that the lower water inlet is blocked and water enters the middle water inlet and flows out of the upper water outlet is adopted; and therefore, the installation processes are reduced, and the design cost is reduced.
Description
Technical field
This utility model relates to a kind of water cooling plant of mine-used frequency-converter, specifically is that the cooled plate set inside has cooling water channel, and inlet opening that is positioned at the cooled plate bottom and the anti-condensation water cooling plant that is positioned at the apopore on cooled plate top are set on the cooling water channel.
Background technology
Along with developing rapidly of frequency control, frequency converter is as the increasing colliery industry that is applied to of its core apparatus.In the frequency converter use, the selection of its type of cooling plays important effect for the normal operation of frequency converter.Water cooling is adopted by a lot of frequency converter producers as a kind of cooling means; Promptly be designed to cooled plate to the chamber wall that the heating power module is installed; The heat that sends when water in water tank is taken away the work of heating power module through the circulation of the water channel in the cooled plate; Reduce the module temperature, guarantee the frequency converter operate as normal.On the water cooling frequency converter that uses now, a lot of producers have designed a water channel on cooled plate, i.e. an inlet opening and an apopore.According to the liquid flow principle, the bottom in cooled plate is generally all designed in the inlet opening, and the apopore design is on the top of cooled plate.When having only the apopore band of position that the heating power device all is installed; Because cooling water infeeds from the bottom; Water temperature is lower; Make the temperature of lower of cooled plate reduce, be lower than enclosure interior, at this moment the dewfall phenomenon will occur at the inner surface of cooled plate because equipment operation has working temperature in himself the chamber.And the condensed water that dewfall occurs can cause inner components and parts fault, brings production safety hidden danger.At present a lot of producers have adopted the cooled plate inwall to smear antifogging coating during design, have not only increased installation procedure and design cost, and have not fundamentally solved chamber wall condensation trouble.
The utility model content
The utility model the dewfall phenomenon occurs to the cooled plate inwall that flame proof water cooling frequency converter exists, and brings above-mentioned deficiencies such as potential safety hazard, and a kind of anti-condensation structure of novel water cooling frequency converter is provided.
The technical scheme of the utility model is: a kind of mine explosion-suppression frequency converter anti-condensation water cooling plant; The cooled plate set inside of described anti-condensation water cooling plant has cooling water channel; Cooling water channel is provided with inlet opening that is positioned at the cooled plate bottom and the apopore that is positioned at cooled plate top, and the middle part of described cooled plate is provided with the inlet opening.
Preferably: described apopore and inlet opening are provided with joint.The beneficial effect of the utility model is: the utility model adopts the cooling water channel cool cycles; When the heating power device all being installed, the dewfall phenomenon do not occur, adopt and block middle inlet opening for assurance cooled plate top and the bottom; The water inlet of inlet opening, below, top apopore water-out manners; When guaranteeing that cooled plate has only top that the heating power device is installed, the dewfall phenomenon does not appear, and to adopt and block the inlet opening, below, middle inlet opening intakes, and top apopore water-out manners had both reduced installation procedure, had lowered design cost again.
Description of drawings
Accompanying drawing 1 is the external structure of the utility model technology specific embodiment;
Accompanying drawing 2 is the utility model technology water channel cut-away view.
Embodiment
The utility model specific embodiment shown in Fig. 1 to 2: the inner cooling water channel cooling cycle structure that adopts of the utility model cooled plate, the outside is made up of 2,3 and 1 apopores 1 in 2 inlet openings.When frequency converter cooled plate inwall top and the bottom all are equipped with the heating power device, need the water pipe plug to block middle inlet opening 2, cooling water is got into by inlet opening, below 3; Cooling water channel in cooled plate arrives top apopore 1; Water is discharged, take away heat, reduce the temperature of power model.Because the cooled plate top and the bottom all are equipped with the heating power device, the cooled plate inner wall surface the dewfall phenomenon can not occur; When frequency converter cooled plate inwall has only top the heating power device is installed; When the bottom does not have installing device, need the water pipe plug to block 3 holes that intake, below, cooling water is got into by middle inlet opening 2; Cooling water channel in cooled plate arrives top apopore 1; Water is discharged, take away heat, reduce the temperature of power model.Get into the cooling water of cooled plate below water channel,, form stagnant water owing to do not circulate; Temperature is consistent with the inside cavity temperature all the time; The dewfall phenomenon can not occur, therefore need not increase operations such as smearing antifogging coating, fundamentally solve frequency converter water cooling mode cooled plate inwall dewfall phenomenon.
