Shenzhen Envicool Technology Co Ltd

Envicool quickly surged to the daily limit up in early trading on August 25, then reopened the board during the session before sealing it again. As of press time, the stock was at 60.23 yuan per share, with more than 220,000 lots queued at the limit-up price. The previous evening, Envicool disclosed its 2026 semi-annual report. In the first half of the year, it achieved operating revenue of 3.017 billion yuan, up 17.24 percent year on year, while net profit attributable to the parent company was 185 million yuan, down 14.32 percent year on year. Net cash flow from operating activities was 61.872 million yuan, up 126.45 percent year on year. The company's electronic cooling segment has drawn strong market attention because it covers businesses related to liquid-cooled computing power. In the afternoon of the same day, the liquid cooling server concept continued to climb. Kangsheng, Envicool, and Yilida had hit limit up earlier, Jinfu Technology hit limit up in the afternoon, and Tongfei and Shenling Environment led the gains.

Amid AI bubble worries, institutional investors and engineers are zeroing in on essential infrastructure like liquid cooling systems and high-speed optical transceivers, where two Chinese companies are major global players: Shenzhen Envicool Technology and Zhongji Innolight. Envicool is a leader in data center temperature control, buoyed by mandatory upgrade demand for cooling systems to handle scorching AI chips, and enjoys a business moat from high switching costs. Zhongji Innolight holds the number one global position in 800G and 1.6T high-speed optical transceivers, counting Big Tech firms in Silicon Valley as key customers. This reflects how, in advanced bottleneck technologies, business needs often transcend geopolitical barriers, and first-mover advantages allow companies to sustain premium gross margins early in a new product cycle.
