1 . For aesthetics , the radiator wrapped.

 

Interpretation: When fitting the radiator is actually wrapped in a very unscientific, its main one is to reduce the harmful effects of the radiator heat dissipation. After the heat sink is wrapped up , because the air convection is reduced, the cooling effect will be reduced up to about 30% , resulting in energy waste . Secondly, the radiator is wrapped , the hood will form a health corner, easily deposited dust, bacteria and insects . When , after the start of heating , dust and bacteria as the air convection and houseful flying, cause harm to human health . In addition , this approach can lead to deformation heating cover , maintenance inconvenience other issues.

 

2 . The mix of various materials radiator .

Interpretation: The mix of various materials radiator can cause a lot of security risks of production, especially aluminum radiator , must pay attention to this point , to avoid mixing with other materials of the product installation . First, because the drag coefficient of different materials are different , this will cause the existing heating system out of balance , potential difference is formed , because of the potential weak electrochemical corrosion and formation of sink hole , resulting in leakage. Secondly , in general, lightweight radiator caliber are relatively small, if mixed with cast iron radiators , likely to cause system hydraulic imbalance , Heating calorie deficiency .

 

3 . aluminum radiator afraid of corrosion .

Interpretation: Although aluminum radiator corrosion strong antioxidant , but it prone to corrosion and alkali chloride corrosion. Therefore, when the heating system water is alkaline, PH value which is higher than 7 , or when higher levels of chloride ions , when the radiator on the presence of corrosive leakage risk .

 

4 .Product is not afraid of no weld corrosion.

Interpretation: Some businesses in the production of steel radiator when the publicity mislead consumers - product no welding gap , smooth wall , afraid of corrosion . In fact, " no welds , smooth wall " does not mean we can anticorrosive steel radiator . Because corrosion of steel radiator did not occur in the weld , which is the principle of the corrosion of steel oxygen corrosion decision.

 

5 .organic , inorganic coatings same effect.

Interpretation : It is now common on the domestic market, two radiators internally coated anticorrosion coating types are organic and inorganic coatings. In general, inorganic coatings than the cost of organic coatings is high, the process is more complex , process requirements are strict , and its preservative effect is superior to organic coatings . Currently, the market also appeared in the two processes into one of the products, is based on the inorganic coating and then add a layer of organic coating, so the radiator would be better corrosion
