Heat exchange plate, heat storage device and drinking water equipment

The invention relates to the technical field of water drinking, and provides a heat exchange plate, a heat storage device and water drinking equipment. The heat exchange plate is provided with a purified water outlet and a purified water inlet, a flow channel for purified water to flow is arranged in the heat exchange plate, one end of the flow channel is communicated with the purified water inlet, and the other end of the flow channel is communicated with the purified water outlet; protrusions are arranged on the inner wall of the flow channel and suitable for increasing the heat exchange area of the inner wall of the flow channel and purified water. According to the heat exchange plate, the protrusions are arranged on the inner walls of the flow channels, the heat exchange area of the inner walls of the flow channels and purified water is increased through the protrusions, the heat exchange coefficient of the flow channels is increased, and the heat exchange performance of the heat exchange plate is improved.
