Definitions

  • the invention relates to a heat exchanger according to the patent claim 1.
  • Evaporators are known in which the two-phase refrigerant is distributed from an inflow channel to a flow-through device, preferably tubes, in particular flat tubes. After flowing through the flat tubes, the vaporous refrigerant exits the evaporator via an outflow channel.
  • the uniform distribution of the liquid refrigerant in the entire length of the inflow channel presents difficulties.
  • the reason for this is, inter alia, the formation of different flow forms as a function of the operating state.
  • the segregation of the homogeneous two-phase refrigerant mixture at the entry of the evaporator also plays a special role over the length of the inflow channel. Individual pipes are thus supplied exclusively with refrigerant vapor, whereby the evaporator performance deteriorates.
  • the refrigerant is only distributed to a small proportion (typically 1/3, 1/4 or 1/8) of the flat tubes and further deflected in several blocks and thus passed through the evaporator.
  • the refrigerant in the individual collectors is intermixed by internals such as partitions, diaphragms, so that higher pressure losses occur are to be expected in the evaporator unit.
  • the ratio of the pressure differences in the distribution unit (injection pipe + distribution unit for the 1st block) and the entire block (flat tubes + deflections between the blocks) is in the range of less than 3.
  • the invention has for its object to provide an improved heat exchanger, which in particular in the heat-transmitting part of the evaporator - the evaporation section or, evaporator unit - realized low refrigerant side pressure losses, This object is achieved by a heat exchanger with the features of claim 1.
  • the heat exchanger in particular for a heating or air conditioning in a motor vehicle, with a via a distribution unit with a refrigerant medium fed and flowed through by this and after only one deflection (two-block design) formed in the depth in a deflection unit around evaporator unit, wherein the distribution unit is designed in the sense of a uniform distribution of the refrigerant medium over the entire evaporator width. Due to the additional internals in the distribution unit, the two-phase refrigerant is thus distributed evenly over the entire evaporator width on the flat tubes and deflected only once.
  • a design of the distribution unit in terms of a ratio V of the pressure difference between the pressure difference in the distribution unit on the one hand and the pressure difference in the evaporator unit on the other hand, which is greater than 3.
  • An increase in the ratio of the pressure differences is necessary for a homogeneous distribution of the refrigerant in the distribution unit and thus leads to an increase in the specific cooling capacity due to a better temperature profile.
  • a design of the distribution unit in the sense of a ratio of the pressure difference between the pressure difference in the distribution unit on the one hand and the pressure difference in the evaporator unit on the other hand be provided in the range between 3 and 70.
  • a design of the distribution unit in the sense of a ratio of the pressure difference between the pressure difference in the Distribution unit on the one hand and the pressure difference in the evaporator unit on the other hand be provided, which in a range of 3 to 30 at a refrigerant edium mass flow of 30 kg / h on the one hand and 30-70 at a refrigerant medium mass flow of 250 kg / h lies.
  • FIG. 2 and 3 also show a pressure-enthalpy diagram schematically illustrated a refrigerant circuit of an air conditioner, wherein essential points of the refrigerant circuit were provided with digits, which were shown according to the pressure-enthalpy diagram.
  • An embodiment of the invention provides in particular for a deflection unit free of any intermediate mixing means.
  • a further embodiment provides a pressure distribution element in the distribution unit in the sense of a distribution of the refrigerant medium in parallel to all through-flow or flow around tubes, in particular flat tubes, the evaporator unit.
  • a pressure distribution element for example, the installation of an additional pressure loss element at the evaporator inlet (before evaporation) for the distribution of the refrigerant can be applied in parallel to all flat tubes via the Velvet width of the evaporator may be provided so that all flat tubes are supplied evenly with liquid and gaseous refrigerant (this pressure loss element has no effect on the cooling capacity). This results in a large ratio of pressure loss in the refrigerant distribution at the evaporator inlet to the pressure loss in the evaporator network (evaporator section).
