Embodiment Construction

[0041] FIG. 3 is a schematic cross-sectional view of the portable blackbody furnace 100 of the present invention. As shown in FIG. 3 , the portable blackbody furnace 100 includes a metal body 102 with a cavity 104 , a shield 108 disposed at the opening 106 of the cavity 104 , and two first shields disposed in the shield 108 . A heater 110 , a plurality of second heaters 112 disposed around the metal body 102 and two temperature sensors 114 disposed in the metal body 102 .

[0042] The cavity 104 can be a cylindrical cavity with a radius of 10 mm, and the end inside the metal body 102 is in a tapered shape. Preferably, the heat content of the metal body 102 is greater than 200 J / K, and its radial thickness is greater than 5 mm. The second heater 112 is a heating wire tightly wound around the outer wall of the metal body 102 . Preferably, the outer wall of the metal body 102 has several grooves, and the second heater 112 is a heating wire embedded in the grooves. The flow dir...

Abstract

The present invention relates to a portable black body furnace. It includes a metal self-body with a hollow cavity, a cover plate placed in the opening position of said hollow cavity, at least a first heater placed in said cover plate, several second heaters placed around said metal self-body and at least a temperature sensor placed in said metal self-body. Said hollow cavity in the tail end of said metal self-body is made into the form of pointed cone. Optimally, the heat capacity of said metal self-body is greater than 200 joule / k, and its radial thickness is greater than 5mm. The external wall of said metal self-body is equipped with several recessed grooves, and said second heater is the heating wire inlaid in said recessed grooves.

Description

technical field [0001] The invention relates to a portable blackbody furnace, in particular to a portable blackbody furnace which can be used for temperature calibration of an ear thermometer. Background technique [0002] FIG. 1 is a schematic cross-sectional view of a conventional blackbody furnace 10 for temperature calibration of an ear thermometer. As shown in FIG. 1 , the blackbody furnace 10 includes a thin metal piece 20 , a heater 22 , and several temperature sensors 24 . The thin metal piece 20 forms a cavity 14 and has an opening 16 . In order to avoid heat loss, the space between the thin metal piece 20 and the casing 28 is filled with a heat insulating material 26 . When performing temperature calibration, the temperature of the thin metal piece 20 is first adjusted to a predetermined value (for example: 38°C) by the heater 22, and then the sensor head of the ear thermometer to be calibrated is extended through the opening 16. The temperature of the cavity 14...
