LaVida's external circulation car won't be too hot for a while. Go and check, the small water tank is blocked and changed, and there is hot air in the internal circulation.

Let me help you answer your question. This is normal. Because of the external air cooling, the external circulation is not well heated by the warm air tank. Internal circulation can slowly heat the wind in the car, so there is a temperature difference between internal circulation and external circulation. This is normal.

I hope it helps you, but forget to adopt it.
