According to data released by the National Energy Administration on July 30th, as of the end of June 2026, over 180000 high-power charging guns have been built nationwide. As the construction of charging facilities extends towards improving service quality, the heat dissipation capacity of gun lines and power modules has become an important consideration in equipment selection. Xi'an Tiantai Electronics Co., Ltd. has deployed HPC cooling modules and charging host cooling modules to provide thermal management support for supercharging equipment.

Behind this demand is the change in the intensity of energy replenishment network usage. At the same press conference, it was revealed that during this year's May Day holiday, the national highway charging capacity reached 94.9314 million kilowatt hours, an increase of 14.09% in daily charging capacity compared to the Spring Festival. Vehicle centralized energy replenishment ensures that the station not only has sufficient gun positions, but also requires equipment to remain available during continuous service. After the charging power is increased, whether the supporting system is matched directly affects whether the equipment capacity can be fully utilized on site.

From a technical perspective, liquid cooled supercharging involves different heat dissipation objects. Gun line cooling mainly processes the heat generated by cables and connection parts, while host cooling serves power conversion and other processes. The location, heat load, and installation conditions of the two are different, and the performance of the entire equipment cannot be judged solely by "using liquid cooling". The project selection still needs to clarify the cooling range, operating conditions, and overall validation results. The HPC cooling module developed and produced by Xi'an Tiantai forms a closed cycle with a high-power charging gun cable, using a circulating medium to bring heat to the radiator, and then heat is exchanged through a fan. From this, it can be seen that liquid cooling does not mean completely eliminating the fan, but rather changing the path of heat transfer from the heating area. The matching between pumps, pipelines, and radiators is the foundation for this system to function effectively. For equipment manufacturers, cooling solutions need to be considered simultaneously during the structural design phase. The space left for the radiator inside the cabinet, the direction of the pipelines, and the maintenance channels will all affect subsequent assembly and maintenance. If the cooling unit is added only after the prototype is completed, the layout may need to be readjusted. Clarifying thermal management requirements in advance is beneficial for reducing repeated modifications during overall machine debugging.

In the batch delivery process, the test results of a single prototype cannot replace the consistency of the entire batch of products. According to publicly available information from the company, the Xi'an Tiantai HPC production line adopts digital process management; Product offline testing includes sealing inspection, as well as performance tests such as flow rate, pressure, heat transfer capacity, and electrical control interfaces. The test results are linked to product information, and such records can provide a basis for subsequent quality traceability. From an operational perspective, on-site maintenance is also an essential part of evaluating liquid cooling solutions. How to check the cooling medium, whether the joints are easy to maintain, and whether abnormal alarms can help locate problems are all related to maintenance efficiency. Especially in scenarios where equipment is scattered, whether the maintenance process is clear will affect the time for troubleshooting. Therefore, the procurement process requires simultaneous verification of equipment parameters, maintenance requirements, and service boundaries.

The effectiveness of the liquid cooling system should also be verified in the entire charging equipment. The actual charging speed may be limited by the battery capacity of the vehicle, the power distribution of the host, and the power supply conditions of the station. The cooling system can provide conditions for high-power operation, but it cannot guarantee the replenishment time of a certain vehicle model alone, nor can it replace the safety testing of the entire pile.

With the continuous construction of high-power charging networks, Xi'an Tiantai liquid cooled supercharging related products are facing more specific engineering needs: they need to adapt to gun lines and hosts, as well as meet the requirements of mass manufacturing, on-site maintenance, and long-term operation. For the industrial chain, the value of thermal management will be more reflected in verifiable operational performance and ultimately implemented in the service capabilities of charging facilities.
