A colorless and transparent engine cooling water jacket testing green part is generated by a photo-curing rapid prototyping technique; a testing pipeline system and a water flowing measurement system are integrated into a flow field testing platform; a testing green part is fixedly arranged on the platform by a special clamp; the rotation speed of a motor is adjusted; typical working condition of the working process of the engine is simulated, and the water flow distribution test for a completely transparent water chamber is carried out so as to gain the cooled water flow field data under different working conditions. The automobile engine cooling water jacket flow field testing system combines the rapid prototyping technique with the modern testing technique, realizes the visualization of the full transparent process of the flow field test of the unseen structure water jacket of the internal chamber of the automobile engine, improves the monitoring of the cooled water jacket water flow performance test, and provides more complete testing base for the structural optimization of the automobile engine water jacket.

Description

technical field [0001] The invention relates to the field of performance testing of an automobile engine cooling system, in particular to a flow field testing system for an automobile engine cooling water jacket. Background technique [0002] The engine cooling system mainly includes: radiator, thermostat, water pump, cooling water jacket and fan. Among them, the cooling water jacket plays a vital role, and its structural design directly determines the thermal efficiency of the engine, the thermal load of high-temperature components, heat distribution and energy utilization. Therefore, studying the cooling capacity of the cooling water jacket and rationally designing its internal structure are important measures to ensure the normal operation of the engine and improve its comprehensive performance.

AI Technical Summary

Problems solved by technology

[0003] At present, the flow field test and numerical simulation of the engine cooling jacket have been widely used in the design and development of the automobile engine cooling system. The flow field test of the engine cooling water jacket can only observe the distribution of the cooling water flow field in a specific position or a local area in the cooling water jacket, and cannot obtain flow field data at all positions. This aspect makes it difficult for researchers to fully understand the cooling water flow field. The detailed information of the complex three-dimensional geometric dimensions of the water jacket, on the other hand, greatly restricts the guiding role of the test data for the research of the cooling performance of the water jacket
