Description

Technical Field

[0001] The utility model relates to the technical field of temperature control devices, in particular to a vehicle urea solution temperature control mechanism. Background Art

[0002] During use, automotive urea solution is often greatly affected by the ambient temperature. When the temperature is higher than 40°C, the urea in the solution begins to decompose slowly, which reduces the effective concentration and produces impurities; since the freezing point of 32.5% automotive urea solution is -11°C, if it is lower than this temperature, it will freeze into a solid, making it impossible to refill the vehicle. The existing application number is: CN201921624636.8, a utility model patent discloses a temperature control device for automotive urea solution, including a temperature control box, a solution box and a water inlet unit; water inlet unit: the water inlet unit includes a water inlet pipe, a water baffle and a water inlet handle... and the edge of the sealing block is arranged corresponding to the inner wall of the top of the liquid inlet pipe, and a liquid inlet rod is provided on the top of the liquid baffle plate. It can solve the problem of cold air discharge, and can also add solution from the liquid inlet unit; it can ensure the quality of the product, grasp the overall temperature and regulate the overall temperature. The above patented urea heating method uses a heating tube inserted into the urea solution for heating. The temperature near the heating tube is relatively high. The urea solution is in a static state. The urea solution near the heating tube will decompose due to heat, resulting in a decrease in urea concentration, which reduces the practicality of the device. Therefore, a vehicle urea solution temperature control mechanism is provided to solve the above problems. Utility Model Content
