Abstract
The utility model provides an air heat exchanger, includes a heat transfer device and the 2nd heat transfer device, the fin that a plurality of intervals of a heat transfer device set up, the 2nd heat transfer device includes a plurality of running through fin and the tubular metal resonator of establishing ties all fins, the interval between the adjacent fin forms first wind channel, the interior cavity formation second wind channel of tubular metal resonator. Because the tubular metal resonator runs through all fins, that is to say that the tubular metal resonator has some settings in first wind channel, also can be directly during the first wind channel of hot -blast process with heat transfer to the tubular metal resonator in, further improve heat exchange efficiency, the tubular metal resonator is equivalent to the skeleton of fin, and many tubular metal resonators carry out the multiple spot to the fin to be supported, prevents the fin because the area lacks the support greatly and takes place to warp.
Description
Technical field
This utility model relates to heat exchanger, especially air heat exchanger.
Background technology
In conventional art, the heat transferring medium of heat exchanger is usually fluid, and the heat air brought by fluid, this kind of heat exchanger is heavier, and installation site is restricted.For alleviating heat exchanger weight and improving the installation of heat exchanger, a kind of air heat exchanger occurs, such as Chinese patent, a kind of waste heat recoverer of Publication No. 104110943A includes some air intake sheet metals and air-out sheet metal, described air intake sheet metal is spaced apart with air-out sheet metal, air intake passage is formed between adjacent air intake sheet metal, air-out passage is formed between adjacent air-out sheet metal, outside normal temperature air enters baking room by described air intake passage, moist hot air in baking zone discharges baking room by air-out passage, air intake sheet metal can be heated by moist hot air through waste heat recoverer, will be preheated when extraneous air is by air intake sheet metal.The air intake passage of this kind of air heat exchanger and air-out passage are sheet metal and different, manufacture cumbersome；Owing to not having skeletal support inside sheet metal, after long-time use, sheet metal is susceptible to deformation, thus affects the smoothness in air channel.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of air heat exchanger, is simple to manufacture conveniently, it is not easy to deform, easy for installation.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of air heat exchanger, including the first heat-exchanger rig and the second heat-exchanger rig, the described first some spaced fins of heat-exchanger rig, described second heat-exchanger rig includes some running through described fin the metal tube being together in series by all fins, spacing between adjacent fins forms the first air channel, and the cavity in metal tube forms the second air channel.Utility model works principle: outside hot blast acts directly on the first heat-exchanger rig, and fin, through the first air channel, is heated by hot blast, completes primary heat exchange；Fin has certain heat after being heated, the heat of fin transfers heat to metal tube by heat transfer；Fresh normal temperature air enters metal tube from the side of the first heat-exchanger rig, and normal temperature air enters after metal tube by the heating of metal tube and takes away a part of heat, thus completes second time heat exchange；Owing to metal tube runs through all of fin, say, that metal tube has part to be arranged in the first air channel, and hot blast can also directly transfer heat in metal tube through the first air channel, improves heat exchanger effectiveness further；Metal tube is equivalent to the skeleton of fin, and many metal tubes carry out multi-point support to fin, prevents fin to lack greatly support due to area and deform.
As improvement, described fin equally be arranged in parallel.
As improvement, the spacing between adjacent fins is 3 ~ 5mm.
As improvement, the opposite sides of described first heat-exchanger rig is provided with baffle plate.
As improvement, described metal tube is copper pipe, and heat transference efficiency is higher.
As improvement, the wall thickness of described copper pipe is 0.1 ~ 0.3mm.
As improvement, described copper pipe is arranged in arrays.
As improvement, the distance between adjacent copper pipe is 35 ~ 45mm.
As improvement, the external diameter of described copper pipe is 9 ~ 16mm.
This utility model is compared with prior art had the benefit that
Owing to metal tube runs through all of fin, say, that metal tube has part to be arranged in the first air channel, and hot blast can also directly transfer heat in metal tube through the first air channel, improves heat exchanger effectiveness further；Metal tube is equivalent to the skeleton of fin, and many metal tubes carry out multi-point support to fin, prevents fin to lack greatly support due to area and deform.

Fig. 2 is heat exchanger opposite side schematic diagram.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of air heat exchanger, including the first heat-exchanger rig and the second heat-exchanger rig.The described first some spaced fins 1 of heat-exchanger rig, the spacing between adjacent fins 1 forms the first air channel；Described fin 1 equally be arranged in parallel, and the spacing between adjacent fins 1 is 3 ~ 5mm, and applicable fin 1 spacing reaches the balance of windage and heat exchange；The opposite sides of described first heat-exchanger rig is provided with baffle plate 3, makes the first air channel only one of which import and an outlet, minimizing hot blast enter the heat losses when of the first air channel.Described second heat-exchanger rig includes some running through described fin 1 metal tube 2 being together in series by all fins 1, and the cavity in metal tube 2 forms the second air channel；Described metal tube 2 is copper pipe, and the external diameter of described copper pipe is 9 ~ 16mm, and the wall thickness of described copper pipe is 0.1 ~ 0.3mm, and described copper pipe is arranged in arrays, and the distance between adjacent copper pipe is 35 ~ 45mm.
Utility model works principle: outside hot blast acts directly on the first heat-exchanger rig, and fin 1, through the first air channel, is heated by hot blast, completes primary heat exchange；Fin 1 has certain heat after being heated, the heat of fin 1 transfers heat to metal tube by heat transfer；Fresh normal temperature air enters metal tube from the side of the first heat-exchanger rig, and normal temperature air enters after metal tube by the heating of metal tube and takes away a part of heat, thus completes second time heat exchange；Owing to metal tube runs through all of fin 1, say, that metal tube has part to be arranged in the first air channel, and hot blast can also directly transfer heat in metal tube through the first air channel, improves heat exchanger effectiveness further；Metal tube is equivalent to the skeleton of fin 1, and many metal tubes carry out multi-point support to fin 1, prevents fin 1 to lack greatly support due to area and deform.
