Abstract
There is provided a thermometer structure including a circuit board, an infrared thermometer, a heat sink and a metal block. The infrared thermometer is arranged on the circuit board and electrically connected thereto. The heat sink is arranged on the circuit board and covers the infrared thermometer. The metal block is in contact with at least one of the circuit board and the heat sink to stabilize a local temperature of the thermometer structure.
Claims17
A thermometer structure, comprising:
- a circuit board;
- an infrared thermometer, arranged on a first surface of the circuit board;
- a metal block, arranged on a second surface of the circuit board;
- and
- a heat shield, covering the circuit board, the infrared thermometer and the metal block, and covering on surfaces of the circuit board and the metal block, and comprising a first window opposite to the infrared thermometer.
88 The thermometer structure as claimed in claim 1, wherein a volume of the metal block is larger than that of the infrared thermometer.
A system for measuring an object temperature, the system comprising:
- a heat shield, comprising a first window;
- and
- a thermometer structure, arranged inside the heat shield, and comprising:
- a circuit board;
- a thermopile sensor, arranged on a first surface of the circuit board and opposite to the first window;
- and
- a heat sink, arranged on the first surface of the circuit board and covering the thermopile sensor, and having a second window opposite to the first window of the heat shield;
- and
- a metal block, connecting to the heat sink via a heat conductive path, wherein the heat conductive path extends from a side surface, other than a surface facing the circuit board, of the metal block to be in contact with the heat sink.
