The shelf thermostat device includes a fixing bracket and a heat exchanger. An electronic device is detachably disposed at the fixing bracket. The heat exchanger is detachably disposed at the fixing bracket and layer arranged in a row with the electronic device. The heat exchanger has a heat exchanging core. The heat exchanging core has a first side and a second side opposite to the first side, and a plurality of internal channels and a plurality of external channels. The internal channels and the external channels are disposed staggered and isolated with each other. An internal air flows between the internal channels and the electronic device. An external air flows to the second side of the heat exchanging core from the first side of the heat exchanging core through the external channels. ## Claims ### Claim 1 A shelf thermostat device applied with at least one electronic device, comprising: a fixing bracket, wherein the electronic device is detachably disposed at the fixing bracket;
