Abstract
The invention discloses a heat exchanger with finned tubes. The heat exchanger comprises a front tube box, a rear tube box and a side plate which is used for connecting the front tube box to the rear tube box, wherein a first medium inlet and a first medium outlet are arranged on the front tube box, a baffle is arranged in the front tube box and between a motor cooling liquid inlet and a motor cooling liquid outlet, the front tube box and the rear tube box are communicated through a plurality of heat discharging/exchanging elements, heat discharging/exchanging elements are arranged at intervals along the flow direction of a second medium, and the heat discharging/exchanging elements are finned tubes. The heat exchanger is characterized in that axes of heat exchanging tubes of adjacent two rows of discharging/exchanging elements are not in a line. Axes of heat exchanging tubes of adjacent two rows of discharging/exchanging elements are not in a line, the flow speed is reduced when the second medium flows to discharging/exchanging elements, the heat exchanging time of the second medium and the first medium in heat exchanging tubes is improved and the heat exchanging efficiency is improved further.
Description
Technical field
The present invention relates to its technical field of heat exchange, specifically, specially refer to a kind of heat exchanger with finned tube.
Background technology
Heat exchanger is mainly used in the heat exchange between a kind of medium and the another kind of medium at present.Present heat exchanger, for example cooler or heater generally comprise housing and the heat exchange element that is arranged in cooler or the heater housing, walk a kind of medium in the tube side of heat exchange element, shell is walked another kind of medium, and two media carries out heat exchange by the tube wall of heat exchange element.But the heat exchange element in existing cooler or the heater generally is the flow direction along the second medium to be arranged in parallel, the axis of the heat exchanger tube in the heat exchange element is in the same plane basically, the second medium is when flowing through heat exchange element like this, very short with the time of contact of heat exchange element, can't carry out more heat exchange, cause heat exchanger effectiveness to descend.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of heat exchanger effectiveness the high heat exchanger with finned tube for the problem of existing heat exchanger heat inefficiency.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of heat exchanger with finned tube comprises the side plate of bobbin carriage before and after forward and backward bobbin carriage and the connection being provided with the first medium import and export at described front header, is provided with dividing plate between the inside of front header, motor cooling fluid import and export; Described forward and backward bobbin carriage is communicated with by some row's heat exchange elements; Some row's heat exchange elements are spaced along the flow direction of second medium, and described heat exchange element is finned tube, it is characterized in that: the axis of the heat exchanger tube in adjacent two row's heat exchange elements is not at grade.
Owing to adopted technique scheme, the axis of the heat exchanger tube in the adjacent two row's heat exchange elements of the present invention is not at grade, when second medium flows through heat exchange element like this, flow velocity will reduce, thereby improved the time of the heat exchange between the first medium in second medium and the heat exchanger tube, and then improved heat exchanger effectiveness.
Description of drawings
Fig. 1 is the structural representation with heat exchanger of finned tube of the present invention.
Fig. 2 is the AA profile with heat exchanger of finned tube of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
The cooler that the below uses with motor describes heat converter structure and the operation principle with finned tube of the present invention in detail.
As depicted in figs. 1 and 2, the heat exchanger with finned tube that provides among the figure, it comprises forward and backward bobbin carriage 1,4 and connect forward and backward bobbin carriage 1,4 side plate 2, be provided with motor cooling fluid import and export 5,6 at front header 1, simultaneously between the inside of front header 1, motor cooling fluid import and export 5,6, be provided with dividing plate 7; Described forward and backward bobbin carriage 1,4 is communicated with by some row's heat exchange elements 3, some row's heat exchange elements 3 are spaced along the flow direction of air or water, heat exchange element 3 is finned tube, it comprises that the fin 32 on some heat exchanger tubes 31 and the fixing some heat exchanger tubes forms, and the axis of the heat exchanger tube 31 in adjacent two row's heat exchange elements 3 is not at grade.
The motor cooling fluid enters in the front header 1 by motor cooling liquid inlet 5, entered into again the heat exchanger tube 31 of part heat exchange element 3 by front header 1, heat exchanger tube 31 by this part heat exchange element enters in the rear header 4, entered into again the heat exchanger tube 31 of the heat exchange element 3 of another part by rear header 4, and the heat exchanger tube 31 of the heat exchange element 3 by another part enters in the front header 1, flowed out by motor cooling liquid outlet 6 at last.The air that the motor cooling fluid flows through outside the tube wall by heat exchanger tube 31 and fin 32 and the tube wall in the heat exchanger tube 31 of heat exchange element 3 or water carry out heat exchange and are cooled.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
