Definitions

  • the invention relates according to the preamble of claim 1 to a cooling device for a liquid operating means of an internal combustion engine, comprising a heat exchanger with diametrically a cooler field enclosed by boxes chambers and a heat exchanger flow temperature-dependent controlling thermostatic valve in a housing connected in one of the chambers with the box wherein an operative fluid-carrying connection in the housing is controlled between an inlet nozzle and a drain nozzle by means of a short-circuit valve actuated by a temperature-controlled main valve of the thermostatic valve.
  • Such a cooling device is known, for example from DE 31 12 202 C2, wherein the heat exchanger for the supplied equipment is introduced into the heat exchanger box, which is opposite to the other heat exchanger box with the integrated thermostatic valve.
  • a disadvantage of this arrangement is that a separate line is provided for the resource supply to the heat exchanger.
  • the invention has for its object to improve a generic cooling device such that a smaller number of coolant lines is required.
  • the box equipped with the thermostatic valve has a dividing wall dividing the radiator panel into counter-flowed sections with an opening controlled by the main valve and that the housing downstream of the inlet nozzle has a leading to the flow section of the radiator panel operative opening, which is effective in the connection to the discharge nozzle short-circuit valve, wherein the cooled operating means is supplied from the connected to the flow section via the other chamber return section via the opened main valve of the thermostat to the outlet nozzle.
  • the invention eliminates the need for a separate resource line to the heat exchanger, since with the invention, the thermostat valve in short circuit directly connects a flow line with a return line and connects the flow line with the return line via the heat exchanger in the cooling case, in a structurally simple manner in opposite flowed through sections of the radiator panel is divided.
  • the cooling device according to the invention can be used as a water or oil cooler, in particular as a water cooler due to the inventively reduced coolant lines, especially in single-track vehicles.
  • the invention is described with reference to a sectionally sectioned heat exchanger with a connected water tank.
  • a cooling device 1 for a liquid operating means of an internal combustion engine comprises a heat exchanger 2 with chambers 5 enclosed diametrically in a cooler field 3 and a thermostatic valve 6 controlling the heat exchanger passage in a housing 7 connected to the box 4 in one of the chambers 5.
  • a service-carrying connection in the housing 7 is controlled between an inlet connection 8 connected to a supply line and a discharge connection 9 connected to a return line by means of a short-circuit valve 11 actuated by a temperature-controlled main valve 10 of the thermostatic valve 6.
  • the invention proposes that the equipped with the thermostatic valve 6 box 5 a dividing wall 14 has the radiator panel 3 in gegeutströmte sections 12 and 13 with a controlled by the main valve 10 of the thermostatic valve 6 opening 15.
  • Next has the housing 7 downstream of the inlet nozzle 8 to a flow section 12 of the radiator panel 3 resource-leading flow opening 16, which is effective in the connection in the thermostatic valve 6 to the outlet pipe 9 blocking short-circuit valve 11. It is achieved that the cooled equipment is fed from the connected to the flow section 12 via the other chamber 5 return section 13 via the open main valve 10 of the thermostat 6 to the outlet nozzle 9 of a return line, not shown.
  • the single figure shows that the heat exchanger box 5 with the partition wall 14 has an integrally arranged thermostatic valve housing 7, which receives an inlet port side 17 integrally formed on a closure cover 18 insert 19, the downstream of the closure cap 18 also integrally formed inlet neck 8 distributed over the circumference openings 20, via which in the cooling case, the operating means of the opening 15 and further the flow section 12 of the radiator panel 3 is supplied.
  • Next serves the insertable into the housing 7 insert 19 as an abutment of a main valve 10 and the short-circuit valve 11 with short-circuiting passage 21 comprehensive unit 22, wherein the main valve 10 forming a valve unit with the short-circuit valve 11 is associated with the interposition of a return spring 23 by means of the insert 19 of the partition-side opening 15 of the main valve 10.
  • a short-circuit passage 21 with a circular cross-section as a short-circuit valve 11, a piston valve 24 is assigned.
  • heat exchanger box 5 with partition 14 including thermostatic valve housing 7 is made in one piece from a plastic, wherein optionally a filler neck 25 is formed.
  • the cooling device 1 according to the invention is preferably used for a water-cooled internal combustion engine of a single-track vehicle.
