Description
Technical field
The utility model relates to a kind of building fence structure heat transfer coefficient on-site detecting device.
Background technology
At present, the on-the-spot method that detects building fence structure heat transfer coefficient mainly contains following several kinds: heat flow meter method, hot case method and unstable state method, and the thermal infrared imager method etc.Multiple wall heat transfer coefficient testing apparatus, particularly on-the-spot test equipment are explored and developed to industry specialists both at home and abroad, and these equipment great majority are based on demarcates hot case method and heat flow meter ratio juris.Wang Zhenwu, Meng Qinglin like Architecture Department of South China Science & Engineering University have improved traditional heat flow meter method, use two-sided heat flow meter method Guangzhou remittance scape new city wall structure thermal resistance has been carried out on-the-spot test; The Zhongjian Building Science & Technology Inst., Beijing uses hot case ratio juris and has developed RX-H type heat transfer coefficient detecting instrument; China has built the beautiful teacher's detail analysis of the money that grinds Architecural Physics research institute of institute and has detected the hot case method and the on-the-spot heat flow method of building wall heat transfer coefficient to be measured that detects of building wall heat transfer coefficient to be measured laboratory the in.Above method still do not overcome install inconvenient, receive shortcoming such as season limit.
ZL200620066046.4 has proposed a kind of on-the-spot ice chest that detects of fence structure heat transfer coefficient that is used to build, and utilizes the artificial temperature difference that detection can be carried out under most weather.But ice chest is only applicable to summer and some areas spring and autumn, uses in the winter time then to be restricted.ZL200620043848.3 has proposed a kind of building wall heat transfer coefficient on-site detecting device; Utilize heating produce the temperature difference and auxiliary heating elimination heat source side to deviate from body of wall to hot-fluid; But can not solve the side direction hot-fluid that hot-fluid flows through body of wall; Just can not guarantee the one dimensional heat transfer of body of wall, cause measuring error to increase.ZL200820158854.2 has proposed a kind of hot case of building wall heat transfer coefficient pick-up unit, can under three-dimensional situation, detect wall heat transfer coefficient, thereby obtain heat transfer coefficient comparatively accurately through the heat flux of indirect measurement body of wall.But the measuring complex of each side direction hot-fluid of hot case causes indirect measuring error to increase, and does not solve in-site measurement problem simply and easily.The device that latter two patents proposes all has only heating function, uses to receive the restriction in season.Above-mentioned latter two patents all is that the characteristic that is directed against construction wall designs, and builds then inconvenient installation of fence structure for roofing, floor etc.But these patents all are the faces that produces a transformation temperature; Measure the temperature difference that detects enclosure wall then; Because those skilled in the art are not the technician of Specialty Design variable temperature face; So the pick-up unit of designing is all complicated, uses inconvenience, has proposed a kind of building enclosure structure heat transfer coefficient on-site detecting device and detection method like ZL200910155875.8.
The utility model content
The purpose of the utility model is to use existing variable temperature product that a kind of building fence structure heat transfer coefficient on-site detecting device is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of building fence structure heat transfer coefficient on-site detecting device; Comprise the temperature difference generation device that is arranged on the fence structure to be measured and be used for testing, receiving the temperature of the inside and outside both sides of said fence structure to be measured and the data collector of hot-fluid; Described temperature difference generation device is the high temperature electric iron; The data collector of said temperature and hot-fluid is temperature sensor and thin slice heat flow meter, and temperature sensor all is connected with data collecting instrument with the thin slice heat flow meter.
Above-mentioned building fence structure heat transfer coefficient on-site detecting device, the electric iron periphery is provided with the thermal-insulating sealing ring.
Adopt technique scheme, the utility model has following advantage: the detection effect of the utility model depends on the high temperature electric iron, the homogeneity of iron plate temperature and the accuracy of temperature adjustment.So use the good thermostatic iron of service property (quality); For example the electric iron of utility model patent 201010107764.2 just can satisfy the needs of the utility model, if soleplate is designed to circle; Be more suitable for the utility model; The utility model mainly utilizes existing thermostatic iron, makes cost low, and is easy to operate.
