POLYMERISATES OF PROPYLENE WITH A WIDE MOLECULAR RATIO Q

Procedure for protecting cable strands

Cable strands, especially their junction points with electric components are often subject to damages if used in an aggressive surrounding, for example, in fuels. Protective measures such as shrinkdown plastic tubings or protecting lacquers do not give sufficient protection. The aim of the invention is therefore to protect cable strands and their junction points with electric components against the attack of aggressive media. To this end, the cable strands are covered by a fuel-resistant plastic, said covering not encompassing the entire length of the cable strand but only that part of the cable strand that is subject to the aggressive media. The inventive method does not require any pretreatment of the cable strands.

Helically coiled evaporator

By comparison with the evaporators used so far in liquid cooling, the helically coiled evaporator eliminates the design-induced disadvantages. It can be produced very cost-effectively, since its manufacture is favourable in terms of outlay on both time and material. Furthermore, it can be cleaned easily and arranged in a space-saving fashion owing to its low overall size. Inside the refrigerant (evaporant) battery, the refrigerant is conducted through the inner tube (comparable to a capillary line) as far as the front end of the refrigerant battery. The evaporating process begins there. The refrigerant is fed back inside the refrigerant battery in the outer tube as far as the starting point. The refrigerant battery is inserted into an outer jacket in which the liquid medium to be cooled effects exchange of heat with respect to the refrigerant using the counterflow method.
