Block "radiator-fan"

of cooling system of the car’s engine


Application in the block "radiator-fan" of a radiator with step of ribs 1,7…2,0 mm, diffuser on an exit from the fan and turn of membranes of a casing on 45є in a direction of a stream of air allows to reduce expenses of capacity for a fan drive on 15…30 % and weight of a radiator of cooling system on 5…16 %.


Cooling device of delivery type of cars’ engines


Advantages of devices: fans in the specified devices work on "cold" air which allows to reduce expenses of capacity for a drive on 10 … 12 %; radiators have more heat dissipation from increased turbulization an air stream; aerodynamic resistance of a path at the expense of dynamic losses on an exit from the cooling device decreases. This allows to reduce expenses of nonferrous metals (copper, aluminium, etc.) on 10…15% and expenses of capacity for a drive of fans on 20…25% therefore to receive economy of fuel on each 100000 cars capacity 50…100 kw – more than 200000 litres.


^ Heater of salon of the car


The heater of salon of the car allows to reduce time of warming up of salon for 30 %, to increase air expense in system of heating and salon ventilation on 24 … 60 % together with reduction of expenses of capacity by a fan drive on 40 … 55 %, to reduce a surface heat outputing a heater radiator by 40 %, to raise efficiency of system of heating at the expense of reduction of losses of warmth with proceeding air on 30 … 40 %.


System of warmth accumulation for car engines

prelaunching preparation


The system provides the engine warming-up to +10 єС after a 17-hours storage on the open stand at an ambient temperature minus 20 єС; reduces the engine wear on 300%, amount of harmful matters blip in spent gases, fuel expense in the period of launching and warming up.
