Abstract:
An aquarium thermostat comprising a ventilation box and a transforming mechanism disposed in said ventilation box such that said transforming mechanism is regulated by a microcomputer control mechanism to effect a production of a heating energy or cooling energy, said transforming mechanism being in communication with the interior of the aquarium by a water admission pipe and a water discharge pipe such that aquarium water flowing through said water admission pipe can be heated or cooled by the heating energy or the cooling energy before flowing back into the interior of the aquarium via said water discharge pipe; and wherein said transforming mechanism includes:a flat duct element connected with said water admission pipe and said water discharge pipe, so that the aquarium water flows through said flat duct element is heated or cooled by the heating energy or the cooling energy; two chips for generating the heating energy or the cooling energy, said chips having a first planar surface in contact with said flat duct element, and a second planar surface opposite to said first planar surface, wherein when said first planar surface is in a heating state, said second planar surface will be in a cooling state, or vice versa; two cooling elements in contact with said second planar surfaces of said two chips for cooling said chips; and two fluid drivers for driving fluid from an outside oft he ventilation box to flow past said cooling elements such that the fluid is let out of said ventilation box.
