Embodiment
Technical scheme provided by the invention is illustrated in more detail with reference to Fig. 1~Fig. 7.
Referring to Fig. 1 and Fig. 6, the embodiment of the present invention provides a kind of heat-exchanger rig, including multiple heat exchange being longitudinally arranged side by side
Device 1, the intersection of longitudinally adjacent two heat exchangers 1 are provided with water sucting part 2, and water sucting part 2 is used for the water for absorbing intersection.
In the present embodiment, heat-exchanger rig is specific available for the air-conditioning of air-conditioning or other similar structures, its heat exchanger 1 between row
It can be surface cooler.
The surface that water sucting part 2 can produce condensed water with heat exchanger 1 is bonded, and such soaking effect is more preferable, and water will not
Permeated at along the intersection of two longitudinally adjacent heat exchangers 1 to both gaps, will not deposit, will not also be carried away by the wind, protected
The security that working space inner electronic equipment where having demonstrate,proved heat-exchanger rig uses.
Referring to Fig. 1 and Fig. 5, multiple heat exchangers 2 refer to two or more heat exchangers 2.In the present embodiment, with upper and lower
It is folded set two heat exchangers 1 exemplified by, wherein underlying heat exchanger 1 be First Heat Exchanger 11, heat exchanger 1 above is the
Two heat exchangers 12.
Under installment state, multiple heat exchangers being longitudinally arranged side by side are folded about 1 and set, positioned at the heat exchange of bottom
The lower section of device 1 can set drip tray 4, certainly, can also be also provided with water sucting part 2.Remaining heat exchanger 1, changed at upper and lower two
Intersection sets water sucting part 2 between hot device 1, and water sucting part 2, which is mainly used in adsorbing caused by heat exchanger 1 above, to be condensed
Water.By taking the present embodiment as an example, water sucting part 2 is used to adsorb condensed water caused by the second heat exchanger 12 above.
Alternatively, water sucting part 2 includes following one of which:Sponge, absorbent cotton, silica gel, water-absorbing resin.
Further, the intersection of two longitudinally adjacent heat exchangers 1 is formed stepped, water sucting part 2 and stepped patch
Close.When mounted, because of alignment error, after each heat exchanger 1 is installed, it is possible that certain dislocation, is embodied in first and changes
After hot device 11, the installation of the second heat exchanger 12, a step can be formed in both intersections.Referring to Fig. 7, water sucting part 2 can be with
Using the structure matched with step, to compensate alignment error so that condensed water can be preferably attracted in water sucting part 2.
In the present embodiment, heat-exchanger rig also includes support member 7, and water sucting part 2 is installed on support member 7.Water sucting part 2
Pasting is in support member 7.Water sucting part 2 can more easily be installed using support member 7.
Referring to Fig. 1 and Fig. 5, support member 7 is installed on the supporting plate 3 of heat exchanger 1, can specifically be connected by screw bolts or other
It is detachably connected.
The heat-exchanger rig of the present embodiment offer is provided below in conjunction with the accompanying drawings.
As shown in Fig. 2 heat-exchanger rig includes First Heat Exchanger 11, the second heat exchanger 12, water sucting part 2 and supporting plate 3.Adopt
First Heat Exchanger 11, the second heat exchanger 12 and two supporting plates 3 are fixed together with tapping screw, drip tray 4 is located at first
The lower section of heat exchanger 11, First Heat Exchanger 11, the second heat exchanger 12 all can be surface cooler.Centrifugal blower 5 is located on the right side of surface cooler, adopts
Water sucting part 2 is fixed on to the intersection of two segment table coolers with tapping screw.Referring to Fig. 1, centrifugal blower 5 is by support 6 with changing
Thermal connects.
As shown in Figure 1, Figure 3, the heat exchanger 12 of First Heat Exchanger 11 and second is stitched together by two supporting plates 3, from
Heart blower fan 5 is located at the right side of heat exchanger 1, and water sucting part 2 is fixed on the intersection of two sections of heat exchangers 1.As shown in figure 3, water sucting part 2
Sponge specifically is used, the back side of sponge is pasted onto in support member 7, and the intersection of heat exchanger 1 is close in the front of sponge.When unit is transported
During row, condensed water caused by intersection can be adsorbed onto on sponge, ensure that condensed water is not taken out of with the wind, this processing mode simply has
Effect, this will not be both added to, will not also improve difficulty of processing.
It can be seen that above-mentioned technical proposal, without in two surface cooler intersection additional designs drip trays, need to only be set in intersection
The support member 7 of a built-in sponge is counted, support member 7 is fixed on the left and right supporting plate 3 of surface cooler by tapping screw
On, assembly difficulty and simple and reliable is reduced, facilitates after-sales service.
Sponge has countless Small Holes gaps, and for sponge, condensed water is immersion liquid.When sponge encounters condensed water,
Due to water infiltration sponge, the liquid level in fine pore is concave, the rubber membrane of the similar tensioning of liquid surface, if liquid level is bending
, it just has the trend to flatten, therefore concave meniscus applies with pulling force to following liquid, liquid is increased along hole wall, when upward
Pulling force it is equal with pulling force suffered by fluid column in hole when, liquid just stops rising in hole, forms capillarity, and then condensed water just fills
The space of sponge is expired, it is therefore prevented that condensed water is taken out of with the wind.
Two surface coolers can not ensure that surface both is generally aligned in the same plane in installation process, and both height occurred in both
Difference, if as shown in figure 1, First Heat Exchanger 11 in the Y direction height be less than the second heat exchanger 12, water sucting part 2 can be designed to rank
Scalariform, to make up this difference in height, avoid the hidden danger that condensed water is taken out of with the wind.
Another embodiment of the present invention provides a kind of air-conditioning, including the heat-exchanger rig that any technical scheme of the present invention is provided.
Specifically, air-conditioning includes air-conditioning between row.
Referring to Fig. 3, water sucting part 2 is located at heat exchanger 1 towards the side of the centrifugal blower 5 of air-conditioning.The arrow bent in Fig. 3
Illustrate surface Flow in Centrifugal Fans 5 of the wind along surface cooler.
Referring to Fig. 1 and Fig. 3, drip tray 4 is provided with positioned at the lower section of the heat exchanger 1 of gravity direction bottom.In the present embodiment,
The lower section of First Heat Exchanger 11 sets drip tray 4, can condensed water effectively caused by access First Heat Exchanger 11.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on accompanying drawing institutes
