Description

A kind of double rows parallel flow heat exchanger and use the air-conditioning of this heat exchanger
Technical field
The utility model relates to the idle call technical field of heat exchangers, especially relates to a kind of double rows parallel flow heat exchanger and the air-conditioning of using this heat exchanger.
Background technology
Heat exchanger is the vitals that carries out the heat conversion in air-conditioning or the refrigeration plant, and its quality directly influences refrigeration.Most of part of traditional heat exchanger is a copper alloy, but along with the rise of copper valency makes the cost of heat exchanger increase greatly.And the price of the relative copper alloy of aluminium alloy is cheaper, and physical property also can meet the demands, so aluminium alloy Alloy instead of Copper alloy will become a kind of trend of air-condition heat exchanger development from now on.
Concurrent flow porous micro-channel heat exchanger is exactly a kind of full aluminium heater of whole employing aluminium alloys, and it has been subjected to increasing concern as the new type heat exchanger of equipment such as a kind of air-conditioning.Existing concurrent flow porous micro-channel heat exchanger generally all is the form of single flat tube; In order to satisfy the refrigeration requirement, need to increase the volume of condenser, so not only increased the weight of whole air-conditioning; And the more aluminum alloy materials of needs; And this type of heat exchanger builds up dust more easily, and easy to clean can not have a strong impact on the heat exchange effect.Be issued to refrigeration demand in order to satisfy in situation than small box; Can adopt double rows parallel flow heat exchanger; And present double rows parallel flow heat exchanger all is flat tubes that front and rear row adopts same widths; Rows of flat pipes heat exchange effect is better before can causing like this, and the effect of rows of flat pipes heat exchange then is relatively poor, does not give full play to the heat exchange effect of double rows parallel flow heat exchanger.
The utility model content
In order to solve the deficiency that exists in the above-mentioned prior art, the utility model has designed a kind ofly can give full play to double rows parallel flow heat exchanger heat exchange effect and double rows parallel flow heat exchanger with low cost.
The concrete scheme of the utility model is: a kind of double rows parallel flow heat exchanger comprises the cold-producing medium access tube and the discharge pipe that are provided with on two headers, the flat tube that is communicated with two headers, the fin between the adjacent flat tube, the header; Described flat tube is made as front-seat narrow flat tube and the wide flat tube of back row.Front-seat narrow flat tube carries out preliminary heat exchange earlier as the windward side when using, and the back wide flat tube of row carries out the heat exchange of the degree of depth, to give full play to the heat exchange effect of double rows parallel flow heat exchanger again as lee face.
Physical dimension as a kind of optimization; The width of above-mentioned narrow flat tube is 6~22mm, and the width of above-mentioned wide flat tube is 8~25mm, with the heat exchange effect of better performance double rows parallel flow heat exchanger; And the requirement of production technology is satisfied in the further standardization of the physical dimension that makes heat exchanger.
As further improvement, above-mentioned header is divided into left header and right header; Left side header is provided with left diaphragm plate left header is divided into upper left chamber and left cavity of resorption; Be provided with right midfeather in the right header right header is divided into right one vertical chamber and right two vertical chambeies, be provided with right diaphragm plate in the right one vertical chamber one vertical chamber, the right side is divided into the vertical chamber in the vertical chamber and the right side on right once; Vertical chamber is communicated with on the access tube and right, and the vertical once chamber in the discharge pipe and the right side is communicated with; So just formed by access tube and got into, successively through vertical chamber, flat tube, upper left chamber, flat tube, right two vertical chambeies, flat tube, left cavity of resorption, flat tube, vertical once chamber, the right side on right one, the refrigerant passage of the circuitous connection of flowing out by discharge pipe at last.Thereby increased the circulation distance of cold-producing medium in heat exchanger greatly, the heat exchange effect is obviously promoted.
Perhaps adopt another kind of mode to improve, promptly described header is divided into equally and is left header and right header; Be provided with right midfeather in the right header right header is divided into right one vertical chamber and right two vertical chambeies, be provided with plural right diaphragm plate in the right one vertical chamber one vertical chamber, the right side is divided into a plurality of right loculuses; Each right loculus is communicated with an access tube, and right two vertical chambeies are communicated with discharge pipe; So just formed by access tube and got into, successively through a right loculus, flat tube, left header, flat tube, right two vertical chambeies, the refrigerant passage of the circuitous connection of flowing out by discharge pipe at last.Thereby the circulation distance of cold-producing medium in heat exchanger increased, and the circulation more even distribution, the heat exchange effect is obviously promoted.
As a kind of optimization of structure, be provided with two or three right diaphragm plates in the one vertical chamber, the above-mentioned right side and the chamber is indulged on right side one be divided into three or four right side one loculuses.So both can reach good heat exchange effect, can simplify production technology again.
In order further to improve heat exchange effect, the width of above-mentioned fin is equal to or greater than the width summation of narrow flat tube and wide flat tube.
In order to satisfy and simplify the demand of production technology, above-mentioned left header and right header are respectively integral structure, can one be processed to form.
A kind of air-conditioning of using above-mentioned double rows parallel flow heat exchanger, above-mentioned double rows parallel flow heat exchanger can be used as condenser or evaporimeter, can be used on the air-conditioning of separate refrigeration, also can be used on the multi-functional air conditioners such as refrigeration and heating.
The utility model is arranged side by side through the flat tube that adopts different in width, the heat exchange effect of double rows parallel flow heat exchanger is not fully exerted, and can dwindles the volume of complete machine, and is simple in structure, with low cost, is applicable to refrigeration plants such as various air-conditionings.
