Title: Portable heat exchange device having arrayed planar elastic vortex tubes
Inventor: CHEN WEIQIANG
IPC: F28D7/00
Filed: 2020-10-01
Granted: 2021-04-01
Abstract: The present invention relates to a portable heat exchange device having arrayed planar elastic vortex tubes, including a left seal head, a right seal head, a tube-side outlet tube, planar elastic vortex tubes, a tube-side inlet tube, mass blocks, a cylinder, flanges, gaskets, a tube sheet-fixing frame, tube-sheet end covers, a tube sheet-fixing collar, a shell-side outlet tube, a shell-side inlet tube, a bracket, and a handle. The planar elastic vortex tubes includes planar red copper vortex tubes and mass blocks. The planar elastic vortex tubes are arranged in an evenly spaced manner to form a tube bundle and are connected to the tube sheet-fixing frame through the fixing collar, and the mass block is connected between the planar elastic vortex tubes. The cylinder is fixedly connected outside the tube sheet and between left and right tube-sheet end covers, and the gaskets are arranged between the end covers and the cylinder for sealing. The left and right seal heads are respectively connected to the other ends of the left and right tube-sheet end covers, and the gaskets are arranged between the left and right tube-sheet end covers and the seal heads for sealing. The heat exchange device enhances heat transfer by using vibrations. The planar vortex tubes are made of red copper, and the copper tube is unlikely to be damaged, which is beneficial to prolonging the service life and reducing noise harm, and can also achieve automatic descaling. Under the action of the mass blocks, inherent characteristics of the tube bundle are changed, so that a vibration characteristic under the induction of the fluid is regulated, thereby further enhancing heat transfer through vibration. A plurality of heat exchange devices may be combined and installed as a one-row array by using the flanges disposed at inlets and outlets, and the connecting tube, and may be flexibly assembled and disassembled according to an actual situation.

Filed: 1998-04-20
Abstract: An apparatus and a method for controlling a degree of attrition or wear of a sealing screw conveying plasticized material are provided. The apparatus includes an opening which intersects the wall of a housing of the screw in the region of the screw threads or in the region immediately neighboring the screw threads. Another opening intersects the wall of the housing. The two openings are spaced apart axially from each other and the pressure sensors connected to both openings. The process involved conveys a plasticized material against a resistance, the resistance being a sealing screw bearing supported within the screw housing. The pressure of the conveyed material is measured at two locations spaced apart from each other in the direction of conveyance. The two locations are disposed on both sides of a resistance body towards which the sealing screw conveys the material. The difference between the two measured values is used to indicate the degree of wear of the screw or its housing, respectively.

IPC: G01V1/36
Filed: 1999-05-18
Abstract: A method relating to filtering coherent noise and interference from seismic data by constrained adaptive beamforming is described using a constraint design methodology which allows the imposition of an arbitrary predesigned quiescent response on the beamformer. The method also makes sure that the beamformer response in selected regions of the frequency-wavenumber space is entirely controlled by this quiescent response, hence ensuring signal preservation and robustness to perturbations. Built-in regularization brings an additional degree of robustness. Seismic signals with arbitrary spectral content in the frequency-wavenumber domain are preserved, while coherent noise and interference that is temporally and spatially nonstationary is adaptively filtered. The approach is applicable to attenuation of all types of coherent noise in seismic data including swell-noise, bulge-wave noise, ground-roll, air wave, seismic vessel and rig interference, etc. It is applicable to both linear or areal arrays.
