Abstract
The invention relates to a heat radiator cold-side wind rate on-site verifying method. A flowmeter which is used for measuring a wind rate of a blower is mounted on a cold-side wind pipe of a heat radiator testing unit and an air discharge pipe of the blower is provided with a verifying bypass; when cold-side wind rate on-site verifying is carried out, the verifying bypass is turned on, a pipeline where a verifying flowmeter is mounted is externally connected with the verifying bypass, an air-discharge baffle plate is additionally arranged at an air discharging outlet of the air discharge pipe and then the verifying is carried out; and after the verifying is finished, the pipeline where the verifying flowmeter is mounted is dismounted, the verifying bypass is turned off, and the air-discharge baffle plate at the air discharging outlet of the air discharge pipe is removed to recover a normal equipment state. With the adoption of the heat radiator cold-side wind rate verifying device provided by the invention, periodic verifying by using the flowmeter for measuring the wind rate becomes feasible and system errors, such as mounting of the flowmeter can be eliminated, so that the heat radiator cold-side wind rate on-site verifying method is simple, feasible and reliable and the problems of measuring accuracy of the flowmeter and on-site comparing and verifying in the heat radiator testing unit are solved.

Radiator performance measuring technology of the present invention relates to having the perfect of radiator performance experimental provision now.
Background technology
Heating radiator is widely used in industries such as Aero-Space, air-conditioning manufacturing, automobile making.The radiator performance proving installation is the testing equipment of radiator performance test, usually adopt the cold limit of the air-breathing analog radiator of blower fan to ventilate, the airduct relative aperture is bigger, the flowmeter heaviness of supporting measurement air quantity, dismounting inconvenience, the installment state of flowmeter often can not satisfy the installation requirement of flowmeter simultaneously, has alignment error, causes measuring error bigger.
Summary of the invention
The objective of the invention is: solve to measure the flowmeter check problem of the cold limit of heating radiator experimental provision air quantity, made the flowmeter periodic check of measuring the air quantity feasible and of the present invention calibration equipment that becomes to eliminate the systematic errors such as installation of flowmeter.
Technical scheme of the present invention is:
The cold limit of a kind of heating radiator air quantity on-site calibrating method is installed the flowmeter that is used to measure fan delivery on the airduct of the cold limit of radiator testing equipment, it is characterized in that, draws the verification bypass on the gas exhaust piping of blower fan;
When carrying out cold limit air quantity field-checking, open the verification bypass, at the external pipeline that the checking flow meter is installed of verification bypass, install wind-discharging baffle additional at the exhaust outlet of gas exhaust piping, carry out verification;
After verification is finished, remove the pipeline that the checking flow meter is installed, closed verification bypass is removed wind-discharging baffle at the exhaust outlet of gas exhaust piping, recovers the normal device state.
Described port in the verification bypass is provided with valve or baffle plate.
Described valve is a kind of of hand valve, pneumatic valve or motorized valve.
The connected mode of described gas exhaust piping and verification bypass is welding.
The invention has the beneficial effects as follows: the cold limit of heating radiator of the present invention air quantity calibration equipment makes the flowmeter periodic check of measuring air quantity become feasible, and calibration equipment of the present invention can be eliminated the systematic errors such as installation of flowmeter, simply, feasible, reliable, solved the accuracy and the on-the-spot comparison check problem of flowmeter survey in the radiator testing equipment.
