The present invention relates to a temperature-controlled aquarium comprising a body, at least one heat conducting plate and at least a uniform cold wafer device； the body has an inner space formed by a plurality of wall surfaces； the heat conducting plate abuts against an outer wall surface of the body； and the cooling chip device The heat-dissipating plate is disposed on the other side of the heat-conducting plate, and the heat-dissipating plate is disposed on the other side of the heat-conducting plate relative to the body； the cooling chip is connected to the heat-dissipating seat； The cold-wafer device controls the temperature of the heat-conducting plate, thereby controlling the water temperature to reach the aquarium constant temperature. The large-area heat-conducting plate achieves rapid and uniform water temperature adjustment, and the heat-dissipating block can quickly cool the wafer. The generated heat is carried away to improve the efficiency of the overall cooling wafer.本發明係一種溫控水族箱，其包含一本體、至少一導熱板及至少一致冷晶片裝置；本體具有複數壁面圍繞形成的一內部空間；導熱板貼靠於本體的外壁面；致冷晶片裝置設置於各導熱板相對於本體的另一側面，且各致冷晶片裝置包含一散熱座及一致冷晶片，散熱座設置於導熱板相對於本體的另一側面；致冷晶片連接於散熱座；藉由致冷晶片裝置控制其導熱板的溫度，進而控制水溫達到水族箱恆溫之目的，大面積的導熱板達到快速且均勻的水溫調節，而散熱座更可快速的將致冷晶片所產生的熱量帶走，提升整體致冷晶片的執行效率。
