Background technology
At present, the knockout that the evaporimeter of all air conditioner industries adopts is all external, and namely knockout is all in evaporimeter outside, and Fen Ji road is very clear outside, even if parallel-flow evaporator.Balanced flow beats the hole that size does not wait on the internal spacer of liquid collecting (gas) pipe sometimes.And knockout of the present utility model is mainly used in the inside of miniature microchannel metal circular tube evaporimeter liquid collecting (gas) pipe, can't see knockout in appearance.Because miniature microchannel metal circular tube evaporimeter is different from other various forms of A/C evaporators, it in the distance being no more than 200mm, completes heat absorption by hundreds of thousands of miniature micro-channel tubes, do not resemble other A/C evaporators and complete heat absorption by the flow process of how many meters of length.Therefore, it proposes higher requirement to the uniformity of separatory.
Utility model content
The purpose of this utility model is to solve the uneven problem of miniature microchannel metal circular tube evaporimeter separatory, allowing the flow of hundreds of thousands of micro channel heat exchanging tubes reach uniformity.
In order to realize above-mentioned requirements, the utility model devises a kind of built-in knockout for miniature microchannel metal circular tube evaporimeter, it comprises knockout supervisor and discharge, the separating tube being fixedly installed and comprising more than one and one is closed in one end of knockout supervisor, separating tube stretches in discharge, and being fixedly connected in discharge by knockout supervisor is closed, discharge is provided with the interface connecting micro channel heat exchanging tube.Several separating tubes in usual insertion knockout supervisor are formed by connecting by welded seal.
In order to ensure that the flow entering all micro channel heat exchanging tubes reaches uniformity, the diverse location on separating tube is distributed with the gas liquid outlet in identical or different aperture.
Also can be provided with gas liquid outlet end stretching on the separating tube in discharge, the gas liquid outlet end stretching into the separating tube in discharge can be arranged on the medium position of discharge usually, the angle of the flexible one-tenth different directions of gas liquid outlet end; Or the gas liquid outlet of different directions can be provided with on gas liquid outlet end.
Discharge described herein also can be called collector tube according to the medium state difference of internal flow, and the cross section of described knockout supervisor and separating tube is various geometries.Because the inside of discharge has had in micro channel heat exchanging tube is inserted in, space is less, so the external diameter stretching into the knockout supervisor in discharge can between 1 mm ~ 4mm; The external diameter of separating tube also at 1 mm ~ 4mm, specifically can be determined according to the connected mode between knockout supervisor and separating tube.
The separating tube be fixed on knockout supervisor can be made up of two, three or more root pipes, and the tube length of separating tube can regulate according to design discharge demand, can be equally long, also can have length; And the angle of the flexible one-tenth different directions of the port of export of different root pipe.
Preferred version of the present utility model can be: close the separating tube pipe that is less than 1 mm by three internal diameters be fixed on knockout supervisor and form, the direction stretching into the gas liquid outlet end of the separating tube in discharge is respectively 0 °, 90 ° bendings and 180 ° of bendings, and gas liquid outlet end is distributed in the diverse location place in discharge.
A kind of built-in knockout for miniature microchannel metal circular tube evaporimeter that the utility model obtains, separatory is even, when discharge distributes hundreds of thousands of micro channel heat exchanging tubes time, the flow of its hundreds of thousands of micro channel heat exchanging tubes can reach uniformity substantially, realizes abundant, uniform heat exchange effect fast.
