Problems solved by technology

[0003] The downside of glycol is that it is toxic, and in the case of ethylene glycol, it can even be fatal
However, the problem with diesel oil is that it is acidic due to the mixing of moisture and dirt in the diesel oil, causing damage to gaskets in the cooling system, etc., and causing corrosion problems in the system

Embodiment Construction

[0014] The present invention is based on the discovery that clean synthetic diesel can be used instead of water and glycol mixtures as the cooling medium and thus enables cooling over a wide temperature range while overcoming the problem of glycol toxicity.

[0015] Conventional diesel, such as that produced from petroleum, contains many different residual substances. It is these residual substances that make diesel oil harmful to the environment and that it risks damaging entire ecosystems, for example, in seas or lakes. Even if conventional diesel could be used as a cooling medium, it would not be directly applicable for several reasons. First, conventional diesel is not environmentally friendly and thus poses an increased environmental risk. In addition, regular diesel runs the risk of breaking down if moisture and dirt get in, and thus cause corrosion in the cooling system. In addition, it contains volatile hydrocarbons which may be a health hazard. Furthermore, there i...

Abstract

The present invention relates to heat exchange media. In particular, the invention relates to the use of synthetically produced diesel oil instead of water and glycol mixtures as cooling media, for example, as engine coolants for vehicles. The synthetic diesel is environmentally friendly, applicable to a wide temperature range, has an anti-corrosion effect in cooler systems, and has better heat transfer than water.

Description

technical field [0001] The present invention generally relates to heat exchange media that transfer heat or cold from another medium. An example of such a heat exchange medium is vehicle engine coolant. Background technique [0002] Regardless of engine fuel, today's car engines are cooled with water. To avoid freezing of water at low temperatures, diols are usually added. Glycols also function to provide corrosion protection to cooler structures. For a mixture composed of about 50% water and about 50% glycol, the composition typically has a freezing point of about -40°C and a boiling point of just above 100°C. Therefore, there is a risk that the cooling water starts to boil at high temperatures, for example on a hot day. If the composition were changed to 60% glycol and 40% water, the freezing point would drop to about -45°C. However, when the content of diol is higher, the freezing point rises again. [0003] The disadvantage of glycol is that it is toxic, and in the...
