The utility model relates to a water leakage proof structure for a water tank of a solar energy heater. The water leakage proof structure is composed of a thermotube connected with the water tank. The utility model is characterized in that a heat exchanger is arranged in the water level of the water tank, and the heat exchanger is connected and communicated with a condensing terminal of the thermotube by a siphon hole. The heat exchanger is provided with an air outlet inside, and the air outlet in each heat exchanger is communicated mutually by an air exhaust tube of the heat medium, and one end of the air exhaust tube extends out from the water tank and is higher than the water level. The utility model has the advantages of that: the heat exchanger with wings is added for the water tank, which increases the heat emitting area and improves the efficiency of the heat exchange; the water of the water tank is separated from the thermotube, which is the best way to prevent the water leakage in the tube cracking and leave enough time for the reparation. The broken thermotube can be replaced without stopping the water supply, which overcomes the risk of the tube cracking completely.
