Abstract
The invention relates to a heat exchanger beneficial to discharge of condensate water, comprising a collecting pipe, a flat pipe and a fin. The heat exchanger is characterized in that one side of the collecting pipe and the fin are provided with regularly arrayed flat pipe holes, of which size and shape are matched with the size and shape of the flat pipe section; the flat tube is a flat and straight structure arranged in the transverse direction; the pin is a plain film or a corrugated sheet and is arranged in the longitudinal direction, the flat pipe is arranged in the flat pipe holes of a pin pack. The invention has the beneficial effect that instead of being horizontally arranged, the flat tube is now obliquely arranged, and instead of being staggeringly arranged with fold fin-flat pipe-fin, the fin is now arranged perpendicular to the flat pipe, so that condensate water on a core of the heat exchanger, which is produced by system operation can slide to an oblique fin flanging along the vertically arranged fin and then flow out of the core along the flanging without remaining condensate water. The heat exchanger of the invention can not only be applied to an outdoor unit of a single cold air conditioner but also to an outdoor condenser of an indoor evaporator and a heat pump air conditioner.
Description
Technical field
The present invention relates to a kind of heat exchanger technical field, particularly a kind of full aluminium soldering that condensed water discharges channel heat-exchanging structure that declines that is beneficial to.
Background technology
The existing full aluminium soldering channel heat-exchanging that declines is a kind of efficient heat exchanger that adopts full aluminum to make, and the fold fin that it contains the flat tubes of microchannel by many groups and has a shutter conducts heat, and has significantly improved heat exchange efficiency.Also have clear superiorities such as consumptive material is few, cost is low, voltage endurance capability is strong simultaneously, use increasingly extensive at family expenses and business air conditioner field.But up to now, the above-mentioned full aluminium soldering channel heat-exchanging that declines can only be applied on the condenser (off-premises station) of single cold air-conditioning, because this moment, condenser was the heat release duty, evaporated condensation water produces.
And the evaporimeter of air-conditioning (indoor set) is under refrigeration mode, or the condenser of heat pump air conditioner (off-premises station) is when moving under heating mode, all can produce condensed water on the heat exchanger.As shown in Figure 1, the full aluminium soldering channel heat-exchanging core body that declines is made of by being spaced successively flat tube and roll extrusion fold fin, by production equipment special its both ends are all inserted in the header to appropriate depth all flat tubes then, utilize special fixture that whole core body clamping is fixed simultaneously, put into the soldering furnace brazing again, make each parts link into an integrated entity.The defective of this kind structure is: because the heat exchanger of air-conditioning system is in the majority with vertical layout, the little concave arc in bottom (mark 7 among Fig. 1) of roll extrusion fold fin is horizontal straight section, because of the air velocity of family expenses and business air conditioner slower, generally be no more than 3m/s, under the situation that has condensed water to produce, condensed water can't be shaken off capillary effect under the drive of air-flow, freeze and concentrate in the little concave arc frosting, influence the normal ventilation heat exchange of system, and then make whole system normally to move.Even if after system's operation defrost pattern, condensed water can't be discharged equally.
So the braze welding type micro channel heat exchanger of said structure is because have above-mentioned open defect, can only be applied in the outdoor condenser unit of single cold air-conditioning and (be in radiating mode, evaporated condensation water produces), can not be applicable to the evaporimeter (indoor set) of single cold air-conditioning and the air-conditioning system of pump type heat, greatly limit its application.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the objective of the invention is: a kind of heat exchanger that can make condensed water not assemble, easily discharge is provided.
For achieving the above object, the technical scheme that adopts is: a kind of heat exchanger that is beneficial to the condensed water discharge, comprise header, place the blanking cover and the partition that places described header inside of described header end, the flat tube that is connected with described header, and the fin that links to each other with described flat tube, it is characterized in that: the flat tube hole that is in tilted layout according to rule that described header one side and described fin are equipped with that size shape and flat tube cross section be complementary, described fin is the laminated structure of stamping die moulding, vertically be provided with, the flat tube straight structure, lateral inclination is provided with, and places the flat tube hole of described fins set.
The flat tube hole of described fin is equipped with flange, and the flange inner surface of fin contacts with the flat tube intimate, and connects as one by soldering.
Described fin can be plain film, also can be corrugated plate, can be with on the fin and window, and also can not have and windows.
The described production method that is beneficial to the full aluminium micro channel heat exchanger of condensed water discharge is:
1. with production equipment special header one side blow is opened the flat tube hole, with the fin in the direct punching press band of particular manufacturing craft flat tube hole, the flat tube hole on described header and the fin is regular and is in tilted layout, and the cross section of size shape and flat tube is complementary;
2. the side in fin flat tube hole is provided with the flange of punching press fin, and the inner surface of flange and the outer surface of flat tube are complementary;
3. many flat tubes are inserted successively in the flat tube hole of arranging good fin combination (the multi-disc fin is arranged in together), use special-purpose fuse assembly machine again, the flat tube two ends are inserted respectively in two headers that have a corresponding flat tube hole;
4. will place the soldering furnace brazing by the heat exchanger core that flat tube, header and fin are formed, make that each parts on the core body are integrally welded, become a complete heat exchanger.
The invention has the beneficial effects as follows: flat tube is in tilted layout by horizontally disposed changing into, fin is crisscross arranged by fold shape fin-flat tube-fin and changes into perpendicular to the flat tube setting, make on the heat exchanger because the condensed water that system's operation produces, can be under the multiple action of gravity and wind-force, in time be slipped to along the fin of vertically arranging on the fin flange of inclination, and and then go out core body, the accumulation of evaporated condensation water along the flange landing.Processing technology of the present invention is simple, be fit to mechanization large-scale production, with respect to the micro channel heat exchanger that uses now, it is few to have required production equipment, reduced investment, not only can be used for the singly condenser (off-premises station) of cold air-conditioning, also can be widely used in the advantages such as outdoor condenser of indoor evaporator and heat pump air conditioner.
