Abstract

The utility model relates to an improved charger, which is characterized in that a radiator and a control box are arranged on the outside of an cabinet, wherein the radiator positioned on the shell of cabinet is connected with a centralized control module, wires arranged in the control box are switched in the cabinet, the radiator is air-cooled with wing panels and water-cooled with water tank. Because the radiating mode of original charger is changed from internal type to external type, not only the temperature rise problem in the operation of charger is alleviated effectively, but also positive technical safeguard is provided for safely and effectively charging, and the durability of charger is extended relatively. And the external control box can improve the convenience to operating and controlling, while provide technical support for safe and convenient maintenance. The utility model is a helpful improvement.

Description

Improved charger

Technical field

The utility model relates to charger, especially a kind of improved charger.

Background technology

Charger is a kind of electromechanical equipment commonly used in the industry and mining, if can be divided into open and charger closed by structure and purposes, general, open charger is used for operating environment and the better occasion of safe condition more, otherwise, the closed charger then is used for the environment that environmental aspect more badly reaches relative risk, for example easily produces the mine excavation industry of burning or many dust of blast, many fuel gas etc.No matter be any charger, its structure mainly contains the formations such as transformer, A.C. contactor, controllable silicon integration module power device, electromagnetic switch and control circuit that place in the casing.When charger in when operation work, the power device in the foregoing circuit can produce a large amount of heat, if the heat that will successively produce is not discharged in body, then might scaling loss wherein components and parts or influence charging effect.For this reason,, generally all be equipped with the radiator of standard or the axial fan that forced heat radiation is used, and be required to be body when mounted and reserve enough and keep draughty space for open charger.But, for adapting to and guaranteeing the normal operation of charger in special or adverse circumstances, for example, be full of in the operating environment in charging and the charger components and parts easily caused potential safety hazards such as the soda acid steam of corrosion, inflammable and explosive dust and gas, the closed chargers that use in this environment to guarantee the safety of charging operation more.Yet the heat dissipation problem of existing closed charger is to perplex it to charge normal a key problem in technology of operation.Existing closed charger because of three-phase half control or the full-controlled bridge controlled rectification circuits that adopt controllable silicon and rectifying tube to constitute more, silicon-controlled device wherein only is by the radiator of configuration the heat of its generation to be arranged in body, and the casing by metallic plate system is to extraneous distribute heat.But, tens of up to a hundred amperes electric current and the intrinsic heats that forward voltage drop produced of thyristor even, exist cause influencing normal charging operation or scaling loss device may and not enough.In order to solve the heat dissipation problem of closed charger, once adopted the surface area that increases casing---promptly strengthen the technical measures of its area of dissipation.But this measure is except that increasing material, production cost, and its effect is unsatisfactory.Secondly, also because the control circuit of charger and relative voltage, electric current dial gauge, manipulation of switches etc., all be arranged in the casing or casing surperficial, make troubles for operation, observation and the maintenance of charger.

The utility model content

The purpose of this utility model is to be the thermal diffusivity that improves the closed charger and the convenience of operational observations, and proposes a kind of improved charger.This is practical to be to adopt following technical scheme to realize: a kind of improved charger, comprise cabinet, transformer, A.C. contactor, collection control module, radiator, control circuit, it is characterized in that cabinet is respectively equipped with radiator outward and controls case, radiator places the cabinet shell to be connected with collection control module, controls case and is provided with lead access cabinet; Radiator is the fan-cooled radiator that is provided with fin, and radiator is the water-cooling type radiator that is provided with water tank, and water tank is equipped with inlet tube and outlet tube; The central part that the outer shell joint of cabinet is put radiator has and collects the window that the control module is connected; Control case and be made up of casing, control circuit board, voltage and current gauge outfit, switch and adjusting button, voltage and current gauge outfit, switch and adjusting button place the display floater of casing, and control circuit board places and draws lead and plug in the casing

Press the charger that this programme is implemented, because the mode that former charger is dispelled the heat in cabinet is improved to external radiator structure, not only alleviated the operating problem of temperature rise of charger more significantly, and provide reliable guidance for implementing charging safely and effectively, comparatively speaking, prolonged the useful life of charger.Secondly, external control the convenience that case has not only improved operation control, and safeguard that easily charger provides technical support for safety.The utility model is a kind of useful improvement.

Fig. 2 is that the utility model is provided with decomposing schematic representation air-cooled or the water tank type radiator;

Fig. 3 is the fractionation schematic diagram of Fig. 1.

Embodiment

Be described further for embodiment with regard to a kind of air-cooled and water-cooling type radiator respectively in conjunction with the accompanying drawings.Device has devices such as transformer, A.C. contactor, collection control module 14 and control circuit board in the cabinet 1, wherein, collection control module 14 is power devices of caloric value maximum, heating and problem of temperature rise during for solution charging and operation, the utility model is improved to external radiator structure with the radiating mode in the substance, be about to a kind ofly make several alternate side by side tab style radiators 21 by aluminum metal and connect and place on the shell of cabinet 1, adopt the radiator of tab construction, purpose is to increase area of dissipation under condition of equivalent as much as possible.For the heat that charger and module are sent directly distributes, radiator 21 is not only done closely to be connected by screw with module 14, and, with cabinet also be do by screw close-connected, for this reason, the cabinet shell should be by metallic plate weldering system or casting, and just the closed charger forms good thermally conductive interface between inside and outside.With the exception of this, radiator 2 also can be arranged to water-cooled radiator 20, to strengthen " suction " thermal effect.As mentioned above, water tank 200 has screw to do closely to be connected with module 14 and cabinet shell, and water tank can be made as a boxlike cavity, also can make the casing that contains coiled pipe, and casing 200 is provided with water inlet pipe 201 and outlet pipe 202.In order to improve the convenience of charger Operation and Maintenance, the charger cabinet is provided with outward and independently controls case 3, control case 3 by casing 30, panel 31, display screen 32 (being equipped with the gauge outfit that can show output voltage, stream and the signal lamp of relevant information), startup and shutdown switch 34 and regulate button 35, also be provided with control circuit board (diagram slightly) in the case, circuit board is provided with and is not higher than 15V _DCDrive circuit and draw the lead 33 that is equipped with plug, this plug inserts the socket that is connected with related device in charger cabinet.For guaranteeing the sealing of charger, the openend of cabinet 1 is provided with cover plate 11, is equipped with sealing gasket between cover plate and the cabinet or carries out the sealing surface processing, and have screw fastening.Among the figure 13 is input box, and 12 are the output connection box.
