Definitions

  • the invention relates to a self-supporting cooling module, comprising a self-supporting cooling module body which is made of foamed resin material, a reference plane being defined in said cooling module body, wherein components are located in said cooling module body in a first operating position with respect to the reference plane in which all components operably interact, and comprising a plurality of components to be cooled or executing a cooling action, said components executing a cooling action including at least one heat exchanger.
  • Such a self-supporting cooling module is known from DE 10 2004 032 920 A1.
  • Expanding polypropylene (EPP) is proposed as a foamed resin material which comprises excellent strength characteristics so that it can reliably hold the components.
  • the cooling module body consists of two cooperating shells between which the components are arranged, wherein the shells fixes them in a desired functional position. It is further provided to form a drain pan in the lower one of the two shells in which humidity may accumulate which precipitates possibly at several components of the cooling module.
  • a similar cooling module is described in EP 0 547 211 B2 which also uses a double-shell cooling module body made of expanded polypropylene.
  • This cooling module is to be used in an optical device or in a device for analytic chemistry, for example liquid chromatographs.
  • a self-supporting cooling module of the type mentioned in the introductory that the components are introduced into the cooling module body such that they operably the interact also in a second operating position which, with respect to said first operating position, is rotated by 180° around an axis lying in said reference plane.
  • the cooling module body is formed as a double-shell wherein the interface between the two shells is parallel to or within said reference plane.
  • said heat exchanger comprises a condensate drain discharging condensate in a first direction in said first operating position and discharging condensate in a second direction in said second operating position. Therefore, if the cooling module is to be installed in its operating position rotated by 180°, only the respective condensate drain must be closed, so that the device is again functioning and operates failure safe.
  • the condensate drain is a two-way-drain which may in particular be configured as being valve-controlled.
  • control means which drive those components executing a cooling action in response to signals which are issued to the control means by a least one temperature sensor and/or at least one humidity sensor.
  • control means are provided, it is further reasonable to provide a position sensor, said control means controlling the valve of the two-way-drain in response to the signals received from the position sensor to discharge the condensate corresponding to the detected position of the cooling module body in the first direction or in the second direction.
  • expanded polypropylene should be used as a resin material for the cooling module according to the invention.
  • FIG. 1 a cooling module according to the present invention mounted inside a socket of a chassis
  • FIG. 2 a sectional view of the arrangement of FIG. 1 ;
  • FIG. 3 a perspective view of the cooling module body with components arranged therein;
  • FIG. 4 a cooling module according to the present invention mounted in a roof of a chassis
  • FIG. 5 a sectional view of the arrangement of FIG. 4 ;
  • FIG. 6 a perspective view of the cooling module body with components arranged therein;
  • FIG. 7 an overall view of the self-supporting cooling module according to the present invention in an exploded view
  • FIG. 8 a diagrammatic circuit scheme for controlling the cooling module according to the invention.
  • FIG. 1 illustrates a self-supporting cooling module 100 according to an embodiment of the present invention in a first operating position, mounted in a socket within a chassis 200 . Details of cooling module 100 may be better recognized in the sectional view of FIG. 2 .
  • Cooling module 100 comprises a cooling module body formed by two shells 102 , 104 which are joined in a reference plane A, for example by snap locks, so that no additional fixing devices are necessary.
  • Components of the cooling module according to the invention are arranged in respective recesses formed in shells 102 , 104 , for example a heat exchanger 106 and a fan 108 which may be configured as a radial fan.
  • the shaping of shells 102 , 104 is such that components 106 , 108 are retained failure-proof in a first operating position wherein necessary ventilation ducts are also formed by shaping.
  • an air inlet 110 is provided close to the fan, furthermore an air outlet 112 for air cooled by heat exchanger 106 .
  • Air to be cooled reaches a fan 108 via air inlet 110 which fan directs the air to heat exchanger 106 . Cooled air is discharged from cooling module body 102 , 104 via air outlet 112 .
  • Control means 300 are provided for driving heat exchanger 106 and fan 104 .
  • FIG. 4 shows the cooling module according to the present invention mounted in a roof within a chassis 200 .
  • the two-part configuration comprising shells 102 , 104 can be clearly recognized.
  • FIG. 5 shows the reversed arrangement of heat exchanger 106 and fan 108 which operate failure-proof also in this second operating position. Air inlet 110 as well as air outlet 112 are oriented downwardly in the mounted position.
  • FIG. 6 shows a perspective view in a ghosted representation which represents very clearly the reversing with respect to FIG. 3 .
  • Air sucked in by fan 108 via air inlet 110 is cooled by heat exchanger 106 and exits via air outlet 112 .
  • FIG. 7 shows a cooling module according to the present invention in an exploded illustration. Components, such as heat exchanger 106 , fan 108 and control means 300 , are inserted into shell 102 and retained therein.
  • Shell 104 which is to be put onto shell 102 includes air inlet 110 and air outlet 112 and is shaped such that it also fixedly holds components 106 , 108 , 300 .
  • FIG. 8 shows an example of a circuit diagram showing the functionality of control means 300 .
  • Appropriately mounted sensors for example a temperature sensor 302 and a humidity sensor 304 , supply signals to control means 300 which evaluates them and drives fan 108 and heat exchanger 106 in response thereto.
  • Condensate forming at heat exchanger 106 is discharged and reaches a two-way-valve 306 which directs it selectively to one of two condensate drains 308 , 310 . Selection occurs corresponding to the operating position the cooling module shall assume in a mounted state.
  • condensate drain 308 and condensate drain 310 may be performed manually, in a simple way, however, a position sensor 310 is provided which detects the mounting position, i.e. the first or the second operating position and transfers the information to control means 300 which controls two-way-valve 300 correspondingly and opens the path to condensate drain 308 or to condensate drain 310 .
  • the condensate drains are arranged within the cooling module body corresponding to the exit direction as necessary.
  • a cooling module is provided which may be utilized in different mounting situations without any modification, a probably existing display should, however, be mounted according to the first or second operating position for better readability.
