Abstract: A shelf thermostat device and a thermostat system. 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.

Abstract: A heating apparatus with automatic switching heaters includes a control module, a switch module, and a heating module. The control module receives an input power source. The switch module is connected to the control module. The heating module is connected to the switch module. When the control module detects that an amplitude of the input power source is larger than a threshold voltage value, the control module turns on a first switch assembly and turns off a second switch assembly of the switch module so that the heating module operates in a first heating mode. When the control module detects that the amplitude of the input power source is less than the threshold voltage value, the control module turns on the first switch assembly and the second switch assembly of the switch module so that the heating module operates in a second heating mode.

Abstract: A heat exchange device includes a housing, a heat exchange module, and a piezoelectric module. Isolated inner and outer circulation chambers are formed in the housing. The heat exchange module in the housing includes a stack of separated plates parallel to each other. An inner channel communicated with the inner circulation chamber and an outer channel communicated with the outer circulation chamber are defined respectively by both sides of one of the plates and the other adjacent plates. The piezoelectric module in the housing includes a piezoelectric chip, and first and second heat exchange sides thermally coupled to the piezoelectric chip. The first heat exchange side is located in the inner circulation chamber and the second heat exchange side is located in the outer circulation chamber, so that heat can be transferred between the inner and outer circulation chambers via the piezoelectric chip.

Abstract: An air conditioning system includes a control unit, a circulation system, an AC-to-DC conversion unit, and a fan module. The control unit detects an area temperature, controls the compressor unit being in operation or not in operation according to the area temperature and a setting temperature set by the control unit, and control a rotation speed of the condensing fan according to a temperature difference between the area temperature and the setting temperature. When the area temperature is greater than the setting temperature, the control unit controls the compressor unit being in operation and control the condensing fan being in full-speed operation.
