Definitions

  • the invention relates to an arrangement for optimized flow through heat exchangers, and more particularly an evaporator in an air conditioning system of a vehicle.
  • the refrigerant absorbing heat from the air flow thereby evaporates.
  • the air flow is cooled by extracting heat from it.
  • Different types of heat exchangers used as evaporators in vehicle air conditioning units are known.
  • Two-row heat exchangers are typically used as evaporators in vehicle air conditioning units.
  • the collector lines are divided using partition walls. This creates a two-row heat exchanger composed of four heat exchanger registers passed one after the other. In this way, the temperature spread is improved and therefore, a higher transfer capacity can be obtained.
  • throttling stages are inserted into the collector lines to achieve homogeneous flow through the individual evaporator tubes within the register. In this way, registers can be homogeneously passed, even if the ports are disposed on the same side.
  • insertion of throttling stages involves high effort, causes additional pressure losses, and above all, has to be dimensioned and manufactured individually for each size. This makes these heat exchangers very expensive.
  • Two-row evaporators are disadvantageous in that the temperature distribution of the outflowing air is inhomogeneous over the cross-sectional area of the heat exchanger. Furthermore, it is desirable that as little vehicle space as possible be needed for the heat exchanger. Thus, design should aim at high heat exchanging capacities requiring little space. This can be realized through a large heat exchanger surface and/or an advantageous arrangement and flow through the evaporator tubes such as in counter-current or cross-current heat exchangers. Especially good heat transfer from the heat carrier, or the refrigerant, respectively, is to be aimed at. For that reason, series connection of the single heat exchanger registers is advantageous, in order to realize a temperature difference as high as possible between the heat carrier medium and the air over the total heat exchanger surface.
  • a well dimensioned, three-row heat exchanger has advantages. However, in three-row heat exchangers the port lines typically are on different sides, which requires higher tubing effort and makes manufacturing more difficult.
  • FIGS. 6 and 7 a three-row heat exchanger is described where the ports are on the same side.
  • the register which is not homogeneously passed due to the ports being disposed on the same side, is arranged last before the outlet of the air from the heat exchanger. Therefore, no homogeneous temperature distribution over the air outflow cross-sectional area can be realized.
  • All known heat exchangers have the disadvantage that either the evaporator tubes are arranged in two rows or, for three-row evaporator tubes, the ports of the collector lines, to which the evaporator tubes are connected, are disposed on different sides so that tubing of the collector lines is expensive. Additionally, the flow through the evaporator tubes is not optimal, or for improved distribution of the refrigerant, additional inserts such as separating disks or throttling stages are needed in the collector lines.
  • the invention aims at establishing a heat exchanger in such a way that homogeneous temperature distribution over the air outlet cross-section can be achieved. Furthermore, both ports of the heat exchanger are to be on the same side without complicated tubing or inserts in the collector lines made necessary.
  • the problem is solved according to the invention by that the first and the last heat exchanger register, in direction of the air flow, are provided with ports arranged diagonal and the ports of the middle heat exchanger register are on the same side. Therefore the heat exchanger ports are arranged on one side and the junctions between the first and the middle as well as between the middle and the second heat exchanger register are arranged opposite to each other, thus established at a short distance to each other. Especially due to the diagonally connected last heat exchanger register, because of equal pressure losses over all flat tubes of the register, highly homogeneous refrigerant distribution and, thus, uniform surface temperature of the heat exchanger register, are achieved. This circuitry is also known as a Tichelmann system. Subsequently, this arrangement leads to the desired highly homogeneous distribution of the air temperature over the outlet cross-sectional area.
  • collector lines design of the collector lines is simplified. It is not required to determine partitions and/or throttles of the evaporators. Also, high internal pressures in the refrigerant circuit, particularly for systems using carbon dioxide as refrigerant (R744-systems), can be more easily controlled because of simpler structures of the collector lines.
  • the porting lines of the heat exchanger are arranged on the same side. This eliminates expensive additional tubing.
  • the hydraulic flow area of the junction elements being at least 60% of the flow area of the collector lines ensures low pressure losses over the heat exchanger.
  • An advantageous embodiment of the invention indicates the optimal flow area of the junction elements.
  • the pressure losses are kept small, and on the other hand, easy manufacture and assembly of the junction elements are achieved. Also the space requirement of the heat exchanger caused by the junction elements is reduced.
  • the optimum flow area of the junction elements is 75-110% of the flow area of the collector lines.
  • the junction elements are designed as 180° tube bends.
  • the 180° tube bends are a simple type of junction that can be established readily and cost effectively using standard components.
  • the junction elements are established as junction tube sockets.
  • This embodiment discloses a type of junction of the collector lines that saves considerable space and cost.
  • the junction tube sockets are accordingly adapted with their faces to the pierced circumferential surfaces of the collector lines and mounted, for example, by brazing.
  • the heat exchanging area is established as multiple-channel flat tube evaporator tubes connected to the collector lines.
  • Flat tube evaporators particularly multiple-channel flat tube evaporators, enable flexible sizes and versions to be cost effectively established.
  • Multiple-channel flat tube evaporators can be cost effectively manufactured with little machining effort as extruded profile. They are particularly suitable for use at high operational pressures presenting good specific heat exchange capacities at the same time.
  • a port extension line is arranged such that a heat exchanger port is extended into the port area of the other heat exchanger port, in each case.
  • both ports are arranged neighboring each other.
  • both heat exchanger ports can be arranged so that advantageous insertion of the heat exchanger into the vehicle and easier assembly of the heat exchanger are achieved.
  • both heat exchanger ports can be combined to a common heat exchanger porting piece.
  • the top and the bottom collector lines each are combined to respective collector blocks.
  • the corresponding passages of the collector lines and the port sockets for connecting the evaporator tubes are disposed in a collector block. This simplifies manufacture of the heat exchanger as the number of components is reduced.
  • the collector block can be manufactured from, for example, extruded material available as yard goods, and easily and cost efficiently manufactured.
  • the collector blocks are also suited for modular manufacture that can be configured to have different sizes, capacities and porting versions, and are easy to assemble.
  • the passages of the collector lines are connected by junction holes according to the desired path of the refrigerant.
  • the junction holes can easily be made in the collector block by drilling.
  • the junction holes and passages of the collector lines can be closed with plugs as needed.
  • Another advantageous embodiment of the invention is established by arranging end blocks as junction elements on the faces of the collector block. This enables a compact structure of the entire tubing (collector lines, junction elements) to be established.
  • the end blocks can serve for fastening the heat exchanger registers by accommodating the collector lines and for fastening the heat exchanger as a whole by additional mounting of corresponding holders. Also, assembly and standardization of the components are made easier.
  • the end blocks can be varied for different variants of the heat exchanger regarding capacity, arrangement, and integration into the refrigerant circuit, particularly because of the fact that they are composed of junction plates and end plates.
  • junction channels are provided in the junction plates according to the position of the collector lines to be connected, the junction channels being closed by the end plates.
  • heat exchanger ports are integrated into the end blocks. This enables a more compact design of the heat exchanger and, particularly due to the reduced number of components, an assembly-friendly manufacture.
  • the heat exchanger is established to comprise components manufactured as modules. Due to the modular structure, simple design of the heat exchanger with different capacities, dimensions, and connection variants can readily be established.
  • the heat exchanger can be used in air conditioning units with the refrigerant R744.
  • R744 carbon dioxide
  • An advantage of the solution according to the invention is further that the heat exchanger-caused pressure losses are minimized, and the design of the heat exchanger is simplified. Also, due to the modular structure, the heat exchanger can easily be designed in different sizes, and easily extended or made smaller, hence being flexibly adaptable to the respective conditions.
  • a heat exchanger for use in a vehicle air conditioning system includes a plurality of heat exchanger registers.
  • Each of the heat exchange registers has a top collector line and a bottom collector line with a plurality of heat exchanging tubes disposed therebetween.
  • One of the heat exchanger registers has a first port adapted to receive a refrigerant from a refrigerant circuit.
  • An other of the heat exchanger registers has a second port adapted to deliver the refrigerant to the refrigerant circuit.
  • the heat exchanger registers are adapted to transfer heat from an air flow passing thereby to the refrigerant flowing therethrough.
