Problems solved by technology

However, the existing fan blades are generally fixed and assembled by sheet metal brackets. Due to large sheet metal processing errors and assembly errors in the assembly process, the eccentric phenomenon of the installed fan blades and the guide ring will affect the air volume of the fan blades, greatly Reduce the performance of the unit; due to the small gap between the fan blade and the guide ring, the assembly error of the fan blade will easily cause the fan blade to scrape the guide ring and wear the fan blade

Embodiment Construction

[0032] In order to better understand the purpose, structure and function of the present invention, a fan assembly, heat exchanger and its control method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Such as Figure 1-Figure 4 As shown, the fan assembly of the present invention includes a support plate 1, a motor 4, fan blades 2 and a top plate 3, the motor 4 is fixed on the support plate 1, the fan blades 2 are fixed on the output shaft of the motor 4, and the top plate 3 is fixed on the fan. On the support plate 1 above the blade 2, a guide ring 31 is arranged on the bottom surface of the top plate 3, and the guide ring 31 is arranged concentrically with the motor 4. The fan assembly also includes a gap detection device 6 for detecting the fan blade 2 and the guide ring 31. The gap between the gaps, the gap detection device 6 is fixed on the top plate 3 outside the guide ring 31, and the signal of th...

Abstract

The invention discloses a fan assembly which comprises fan blades and a top plate. The fan blades are driven by a motor to rotate. The top plate is arranged above the fan blades. A flow guide ring isarranged on the bottom surface of the top plate. The flow guide ring and the fan blades are arranged coaxially. The fan assembly also comprises a gap detection device for detecting gaps between the blade blades and the flow guide ring. Whether the fan blades and the flow guide ring are eccentric or not is judged by means of the gap detection device. The invention also discloses a heat exchanger and a control method of the fan assembly. The fan assembly is provided with the gap detection device on the top plate, the gap detection device is used for detecting the gaps between the fan blades andthe flow guide ring, so that a condition that the fan blades scratch the flow guide ring to abrade the fan blades is avoided effectively, the service life of the equipment is prolonged, and meanwhile,the blast capacity is ensured and the reliability of a unit is improved.

Description

technical field [0001] The invention relates to a fan, in particular to a fan assembly capable of detecting the gap between a fan blade and a guide ring, a heat exchanger and a control method thereof. Background technique [0002] Existing air-cooled refrigeration equipment requires fan blades to dissipate heat from the heat exchanger. Fan blades are generally used in conjunction with guide rings to ensure that the unit has sufficient air volume to dissipate heat. However, the existing fan blades are generally fixed and assembled by sheet metal brackets. Due to large sheet metal processing errors and assembly errors in the assembly process, the eccentric phenomenon of the installed fan blades and the guide ring will affect the air volume of the fan blades, greatly Reduce the performance of the unit; due to the small gap between the fan blade and the guide ring, the assembly error of the fan blade will easily cause the fan blade to scrape the guide ring and wear the fan blade...
