Definitions

  • this object is achieved in that ends around which the gas stream flows the heat exchanger plates are arranged offset in steps.
  • Both Gas flow ends of the heat exchanger plates at the inlet and at the outlet of the heat exchanger may be arranged offset in steps, but with a step-like offset at the inlet of the heat exchanger a much greater reduction the flow resistances and better control of the distribution of the gas flow leaves. Nevertheless, a step-like offset at the outlet of the heat exchanger can also occur contribute to a reduction in flow resistance.
  • Heat exchangers may not all be staggered, it can for example, only the top or bottom may be offset.
  • the heat exchanger plates can be caused by fluff or other contaminants be occupied, whereby the heat transfer to the gas flowing past and thus the Heat exchange performance is deteriorated.
  • the heat exchanger plates are therefore often like this mounted so that they can be removed especially for cleaning.
  • the heat exchanger plates can be different, so that the Heat exchanger plates are not mixed up and only reinstalled at a certain point may be.
  • the heat exchanger advantageously has safety devices that a reinsertion of each heat exchanger plate only on one for allow this allowed position.
  • These security devices can for example Protrusions or other design measures may be used for each heat exchanger plate are different and with counterparts in the heat exchanger or the place where the Heat exchanger plates are installed, interact.
  • the heat exchanger plates advantageously form channels, each of two plates and delimited by a gas deflection part at at least one end around which the gas flow flows and that of a liquid or gaseous heat exchange medium can be flowed through.
  • a gas deflection part at at least one end around which the gas flow flows and that of a liquid or gaseous heat exchange medium can be flowed through.
  • the gas flow by increasing the Flow resistance of the heat exchanger are throttled very much, so that the Gas flow flowing through the heat exchanger and cooled there is low and the temperature of the gas flow increases faster.
  • the gas deflection parts can be aligned so that the flow losses are as low as possible, whereby they are pivoted again when the gas flow temperature drops to throttle the gas flow and raise the temperature.
  • the heater the household dryer can also be designed so that at maximum continuously Heating power of the gas stream its target temperature with a slight throttling reached by the gas deflection parts. This way both can be exceeded as well as falling below the target temperature of the gas flow by adjusting the Gas deflection parts can be counteracted.
  • walls are shown which form a channel 5 for the gas stream S.
  • the channel 5 runs in front of the inlet of the heat exchanger 1 essentially in a right one Angle so that the gas flow S obliquely with respect to the levels of the heat exchanger plates 2 meets the inlet of the heat exchanger 1.
  • the gas flow S in channel 5 is distributed unevenly on the one hand and, on the other hand, undergoes a throttling that reduces the energy consumption of the tumble dryer elevated.
  • each of the ends of the heat exchanger plates 2 shown on the left are arranged in a step-like manner the lower heat exchanger plates 2 protrude further into the channel 5.
  • these have the same length, so that their rear ends also have an offset.
  • the Gas stream S therefore strikes inlet openings of the valve over its entire width Heat exchanger 1, so that the gas flow S its direction of flow before flowing into only needs to change the heat exchanger 1 to a lesser extent. The flow losses and the Energy consumption is reduced in this way.
  • the heat exchange performance is the same in the present embodiment.
  • the offset is set so that the gas flow S on the heat exchanger plates 2 distributed according to their heat exchange performance.
  • For heat exchange with the gas flow S can in this embodiment all of the aforementioned methods be used.
  • the heat exchanger plates 2 are designed as channels and are flowed through by air as a heat exchange medium, which the tumble dryer of its surroundings.
  • the heat exchanger plates 2 each have two plates 3 on, which are made of a good heat-conducting material and in particular metal.
  • the plates 3 are at the front ends of gas deflection parts which are flowed against by the gas stream S. 4 and sealing at the rear ends, not shown in the figures, via spacers connected to each other and thus form closed channels through which the heat exchange medium or the cooling air flows perpendicular to the plane of the drawing can.
  • the gas deflection parts 4 and the spacers at the rear ends are mutually connected by struts 7 and in this way form a grid, for example as one-piece molded part can be made of plastic.
  • These grids are designed that it continues to be attached to side parts 6, for example by means of the struts 7 can be.
  • the heat exchanger plates 2 and Plates 3 can be easily combined into a stack by the front and the rear ends of a grid with gas deflection parts 4 or with spacers is placed and these grids are laterally connected to side parts 6, so that in this way a frame is formed in which the heat exchange plates 2 and the plates 3 are held.
