The coolant cooler is the most important component of a cooling module. It consists of a cooler core and water tank with all the necessary connectors and attachment elements. The heat generated by combustion in the engine is absorbed by the coolant and discharged to the outside air via the cooler. Coolant coolers are installed in the air flow of the vehicle's front end.
"Easy to find" is the concept for our online catalogue. You can enter the relevant vehicle via our comprehensive manufacturer list, the type designation or the engine code.
In addition, we provide all key product information, such as
at the same time.
Our catalogue app lets you find HELLA products for passenger cars and commercial vehicles quickly and easily. Intuitive user prompting will lead you to the right result in a few steps ─ an easy, straightforward process. Simply select the vehicle type, brand and model, and the appropriate HELLA products will be displayed for you right away. The results are clearly presented, sorted by assembly and product group. They also offer the option of viewing additional information, images and technical data, allowing you to make product comparisons.
The need to provide material safety data sheets is based on Directive 91/155/EEC from March 5, 1991. The data sheets are updated as soon as there is a new revised edition.
Our PREMIUM LINE video will present the product and show you all the benefits.
Dissipating the heat in high-power passenger car engines requires not only high-capacity coolers, but blowers and blower drives capable of providing an efficient supply of cooling air as well. Visco® fans consist of a fan wheel and a Visco® clutch. They are used in engines installed lengthwise and are assembled in driving direction in front of the cooler.
The Visco® clutch establishes, relative to the temperature, the frictional connection to the fan wheel and impacts its speed. The drive torque is transmitted to the fan wheel via wear-free fluid friction. The electrically driven Visco® clutch is directly controlled by sensors. Cooling as needed optimizes the coolant temperature level, engine noise level and fuel consumption
A condenser or cooler fan consists of an electric motor with a flange-mounted fan wheel. They are mounted in front of or behind the condenser or cooler. They remove heat from the refrigerant or coolant via the generated air flow. Air-conditioned vehicles primarily use an additional or more powerful blower.
The cabin heat exchanger is located inside the vehicle cabin underneath the dashboard. The air flow produced by the cabin fan is routed through the cabin heat exchanger, which has coolant flowing through it. The air heated here is then discharged into the vehicle cabin.
