Summary of the invention
The object of the present invention is to provide a kind of on-the-spot ice chest that detects of building enclosure structure heat transfer coefficient that is used for, this device can utilize the semiconductor chilling plate refrigeration to make stable artificial environment, make instrument can adapt to measurement under most of weather, drop to minimum outside environment requirement.
Purpose of the present invention can be achieved by the following technical programs:
A kind of on-the-spot ice chest that detects of building enclosure structure heat transfer coefficient that is used for, comprise temperature sensor, semiconductor chilling plate, heat conductor and insulation material, described insulation material forms the casing of ice chest, one end of casing is an opening end, opening end is lobed edge structure all around, and the confined space of air chamber is arranged in opening end and architectural exterior-protecting construction surface form; The huyashi-chuuka (cold chinese-style noodles) of described semiconductor chilling plate contacts with air chamber, and the hot side of semiconductor chilling plate is connected with the heat conductor of high heat conduction, and semiconductor chilling plate and heat conductor are arranged in the insulation material; Described temperature sensor is positioned over the architectural exterior-protecting construction surface of air chamber correspondence, and is connected with data acquiring control circuit; Described semiconductor chilling plate also is connected with data acquiring control circuit.
As of the present invention further perfect, be provided with the panel of high heat conduction between described semiconductor chilling plate and the air chamber, the huyashi-chuuka (cold chinese-style noodles) of semiconductor chilling plate closely contacts with panel.The effect of high heat conduction panel mainly is in order to strengthen heat interchange and to improve the homogeneity of temperature in the ice chest, is not the necessary condition of this device; Can also adopt other method (as air flow) to improve the homogeneity of ice chest air.
As of the present invention further perfect, be provided with the radiation panel of high heat conduction between described heat conductor and the casing outside air.The effect of the radiation panel of high heat conduction mainly is in order to increase area of dissipation, is not the necessary condition of this device; Also can strengthen the heat radiation of radiation panel by modes such as air-cooled and water-cooleds.
Principle of work of the present invention is, the huyashi-chuuka (cold chinese-style noodles) of semiconductor chilling plate is attached on the panel of the high heat conduction of interior lastblock, and this panel and body of wall or roofing carry out heat interchange by radiation and thermal convection; The hot side of semiconductor chilling plate is connected with the heat conductor of high heat conduction, and this heat conductor closely contacts with the radiation panel of the high heat conduction of box outer surface lastblock again and dispels the heat; Except that opening end, all surround around the ice chest with insulation material; The low-temperature receiver of ice chest is from the refrigeration of one or more semiconductor chilling plates, regulates the refrigerating capacity by the Current Control ice chest of semiconductor chilling plate, thereby sets up stable temperature field in the enclosure space of a side of body of wall or roofing and casing formation.During practical operation, comprise following step:
(1) selectes the representative position of architectural exterior-protecting construction as the measured position;
(2) temperature sensor and heat flow meter etc. is fixed to the measured position;
(3) opening end with ice chest abuts against the measured position and takes reliable measure to fix, and guarantees that enclosure space is airtight good;
(4) each temperature sensor and heat flow meter are connected also power-on with data acquisition controller;
(5) utilize the software kit of exploitation to test automatically and data processing, generate report automatically; Manually check at last.
Compare with the existing on-site detecting device that is used for building enclosure structure heat transfer coefficient, the present invention has characteristics such as price is low, temperature control is accurate, simple in structure, can conveniently carry out the scene of enclosure structure heat transfer coefficients such as building masonry wall or roofing and detect.
