Definitions
- the invention relates to a method and a device for cooling the power electronics of drive units of textile machines. Specifically, it relates to a frequency converter or frequency converter for driving a
- Textile machine comprising a rectifier for rectifying AC, a DC link for smoothing the pulsating DC, a DC converter for generating AC of a different frequency, and a control device for controlling these components.
- Frequency converter for converting an alternating current of the first frequency into one
- AC second, other, usually variable frequency usually include a rectifier for converting the AC frequency of first frequency into a DC, a DC circuit for smoothing the pulsating DC, an inverter for generating AC of the target second frequency and a control device for functional control said components.
- a DC link not only the electrical function is meant here, but also the physical component that performs this function.
- Such frequency converter or frequency find, for example Application in textile machines, in particular spinning machines and roving machines.
- Such machines already have for cooling the drive units and / or suction of textile fluff on a channel which is usually traversed by cool air from the spinning room.
- EP 0478993 A1 proposes a method and a device for cooling the drive units of a ring spinning or twisting machine in which the heat loss of power electronics is dissipated via a heat exchanger. For this purpose, on
- Heat exchanger passed from a collecting duct via a fan branched partial flow of the exhaust air and in turn merged with the main air flow of an exhaust air duct.
- the ventilation device comprises a shaft with openings for supply and exhaust air, which lies on the back of the controller and on one side by a heat sink, which carries on the side facing away from the shaft side control modules, is limited.
- the object of the invention is therefore to provide a method and a device which in a simple manner as safe and low-maintenance operation of a
- the basic idea of the solution according to the invention is to keep the frequency converter as cool as possible and / or at least partially remove it from the warm areas of the Machine out.
- the term "individual” is intended to remove, remotely order, relocate, remove, relocate, dissolve, and the like.
- the invention proposes to efficiently remove heat developed in the intermediate circuit of a frequency converter, to prevent the transfer of the heat developed in the intermediate circuit to other components of the frequency converter, and to simplify the replacement of the component "intermediate circuit".
- Frequency converter developing heat is transferred to these other components. It must therefore be dissipated less heat from these components, which simplifies their refrigeration.
- the spatial separation of the intermediate circuit simplifies and also makes it possible to arrange it on an air duct in which an air flow is guided, which can be used to dissipate the heat developed in the intermediate circuit.
- the other components of the frequency converter can remain at the appropriate place for them, such as in the cabinet of the machine.
- the spatially separate arrangement of the DC link and its execution as a separate module also facilitates its easy replacement, if this should be required.
- the intermediate circuit can be arranged protruding into an already existing channel.
- the cooling flow preferably an air flow, in a preferred embodiment of the invention is cleaned by means of a filter prior to cooling the intermediate circuit.
- the intermediate circuit is formed as a separate module, which may preferably be encapsulated dustproof.
- a frequency converter 1 usually consists of a control circuit 2, a rectifier 3, an intermediate circuit 4 and an inverter 5.
- the rectifier 3 is the input side, a AC / three-phase network 6, wherein the AC voltage is rectified and the output side via connection 7, 8 the DC link 4th is provided as DC voltage.
- Essential to the invention is the detachment or the separate formation of the intermediate circuit 4 and the DC link capacity from the frequency converter, the remaining components, namely control circuit 2, rectifier 3 and inverter 5 as well as the intermediate circuit 4 to be designed as a separate module 13 and 14 respectively can.
- the other components of the frequency converter can thus advantageously remain locally separated from the highly heat-generating intermediate circuit 4 at its preferred position, for example in the control cabinet or in the region of the drive unit.
- Lines 7, 8, 9, 10 and the power line 12 to be connected to the other components of the frequency converter. He is this connected by means of stretched joints 15 with the module 13 of the organs 3/4/5. It is understood that the frequency converter is secured by means not shown screw or other vibration-proof connection on the machine frame.
- This intermediate circuit serves, for example, as a suction channel for textile fluff and / or at the same time as a cooling channel for the drive unit itself.
- the inverter 4 may also have a heat exchanger, in particular in the form of cooling fins 17, wherein it may be sufficient for cooling that the cooling fins protrude into the exhaust air duct 16.
- a filter (not shown here) may be arranged in the exhaust duct 16.
- the detachable unit of the power electronics so for example, the illustrated intermediate circuit 4 be executed closed as a dust-tight unit, so that a
- Power electronics are dissolved and placed in or on an existing exhaust, suction or cooling duct.
- a cooling medium not only air, but any medium in particular liquid cooling media such as water, etc. may be used.
