Part or all of the flow channels 2 are arranged on the non-visible surface 11 and are raised on the non-visible surface 11. Since the visible surface 12 is a plane, the visible surface 12 can be used for other purposes, such as drawing, writing, etc. on the plane.
The flow channel 2 is used for the circulation of working medium (freon) or medium (water) so as to exchange heat with the external environment. The roll-bond heat exchanger is provided with a connector 13 and a connector 14 which are connected with a circulating pipeline of an outdoor unit of the split air conditioner, and the flow channel 2 is communicated between the connector 13 and the connector 14, so that the working medium or the medium can circulate in the flow channel 2.
The flow channel 2 is provided with the bulges on the non-visible surface 11 of the heat exchanger shell 1, so that the decorative performance of the visible surface 12 cannot be influenced, the thickness of the heat exchanger shell 1 can be effectively reduced, and materials are saved. During installation, the heat exchanger is spaced from the wall 400 shown in fig. 9-11 by a preset distance, and the flow channel 2 faces the wall 400, so that the flow channel 2 is directly positioned in the external environment and can directly exchange heat with the surrounding air, and the heat exchange effect is improved.
In one embodiment, as shown in fig. 1-3, more than two flow channels 2 are provided in the heat exchanger housing 1. Wherein, the lengths of any two flow channels 2 are the same or the length difference of any two flow channels 2 is within 30%.

The thickness of the hydrophobic coating 4 and the hydrophilic coating 5 may be adjusted as necessary. Preferably, the hydrophobic coating 4 is a layer of nano-superhydrophobic material. The nano-scale superhydrophobic material layer is formed by coating a nanoscale superhydrophobic material on the outer side surface 12.
The hydrophilic coating 5 is a nano hydrophilic material layer. The nano hydrophilic material layer is formed by coating a nano coating synthesized by a plurality of nano components on the outer side surface 12.
After the surface of the roll-bond heat exchanger is treated by the nano-scale hydrophobic material or hydrophilic material, the particle size of the water drops of the condensed water is about 100 mu m under the action of the nano-scale hydrophobic or hydrophilic material, and the water drops can easily slide off from the surface of the roll-bond heat exchanger.
In one of the embodiments, as shown in fig. 5 and 7, the surface of the roll-bond is coated with a mould proof coating 6.
When the air conditioner is used for refrigeration in summer, the surface of the heat exchanger is wet and easy to mildew, so that mildew is generated, and adverse effects are brought to the normal use of the air conditioner.
After the surface of the roll-bond heat exchanger is treated by the mildew-proof material, the roll-bond heat exchanger is not easy to mildew, and is beneficial to keeping the efficient operation of the air conditioner.

After the surface of the roll-bond heat exchanger is treated by hydrophobic materials, hydrophilic materials or mildew-proof materials, the surface is smoother, the particle size of water drops or water drops is small, and the water drops or water drops can easily slide from the surface of the heat exchanger and enter the water guide device 7.
In one embodiment, as shown in fig. 8, a water pump 8 is disposed in the water guide 7 for discharging water in the water guide 7.
In one embodiment, the outer surface of the water guiding means 7 is coated with a layer 6 of a mould proof material.
