Embodiment Construction
[0029] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.
[0030] This technical solution mainly improves the compatibility test method between the antifreeze liquid and the warm air water tank. It adopts the method of adding antifreeze liquid into the car warm air water tank, and the antifreeze liquid is added to about 95% of the capacity of the warm air water tank. After sealing, put it into a high and low temperature box, and verify it alternately for 500 hours at 105°C high temperature for 120 hours and above, and -40°C low temperature for 48 hours. After the test, disassemble the flat pipe of the warm air water tank to confirm whether there is gel paste substance on the inner wall of the p...

The invention relates to a compatibility test method of a vehicle antifreezing solution and a warm-air water tank. Through performance detection of the antifreezing solution, material detection of thewater tank and multi-round high-low temperature simulation verification of the compatibility of the antifreezing solution and the warm-air water tank, high-low temperature simulation verification ofthe compatibility of the currently used antifreezing solution, other brand antifreezing solutions and the warm-air water tank is carried out, so that optimization improvement of the antifreezing solution is finally completed, and product quality is improved. According to the key point of the technical scheme, the antifreezing solution is added into the warm-air water tank to simulate the actual working condition of the whole vehicle, and high-low temperature simulation verification is carried out for 500 hours, so that the compatibility of the antifreezing solution and the warm-air water tankis verified within one month, and other brands antifreezing solutons are added for simultaneous verification, so that the incompatibility, caused by the antifreezing solution and the water tank, is quickly verified, and the working efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of engine detection, in particular to a method for testing the compatibility of an automobile antifreeze fluid and a heater water tank. Background technique [0002] Car heater is a kind of engine antifreeze as heat source, which is used by most vehicles at present. When the air conditioner is heated in the warm air mode, when the antifreeze flows through the heater water tank, the blower fan will exchange heat from the heater water tank to the In the cab, it plays the role of heating and defrosting; according to the national standard (GB-11555-2009), the whole vehicle should meet the functions of heating, defrosting and defogging. [0003] Pure organic antifreeze does not contain silicate components, is safe and environmentally friendly, and has long-term protection, which can avoid the formation of silicate gel deposits; at the same time, it adopts ionic film passivation technology to form a dense oxidatio...
