Figure 33. Radiator and electric fan:
1 - radiator; 2 - electric fan switch sensor; 3 - electric motor; 4 - casing; 5 - impeller; 6 - rubber cushion; 7 - drain plug.
The radiator core consists of aluminum tubes and aluminum cooling plates, it is attached to plastic tanks and sealed with rubber gaskets. To increase the efficiency of the radiator, the cooling plates are stamped with a notch, causing turbulent movement of air through the radiator. The radiator is made two-way with a horizontal partition in the left tank, as a result of which the liquid passes through the upper tubes into the right tank, and then through the lower tubes enters the lower cavity of the left tank.
The elimination of soldering from the technological process and the use of aluminum reduced the labor intensity of manufacturing the radiator, and also significantly reduced the weight.
The radiator does not have a filler neck, the upper branch pipe of the left tank is connected by a hose to the expansion tank. The left tank of the radiator is also equipped with inlet and outlet pipes. The right tank of the radiator has a drain plug 7 and a sensor 2 for switching off the electric fan.
The radiator is mounted on three rubber cushions 6: two at the bottom are inserted into the holes of the front cross member of the body, one at the top is pressed by a plate using two nuts. Rubber gaskets between the core and tanks, as well as rubber cushions of the supports, make the radiator insensitive to vibration loads.
