Description

Air-conditioner outdoor unit

One. technical field:

Air-conditioner outdoor unit one. technical field: this case relates to the manufacturing of various air-conditioning air-conditioner outdoor units, relates in particular to the raising heat exchange efficiency of off-premises station.

Two. background technology:

Fig. 1 is the side-looking plan structure figure of known off-premises station.Because the design in house, main room majority are back of the body north, face south, so front 1 majority of off-premises station is towards south.The condenser of known off-premises station all is the horizontal L shaped setting of adopting side-looking to overlook, all leave the louvre 4 that to look at condenser side 12 straight in case side 3, like this, not to be exactly in the afternoon in the morning, solar thermal energy can directly be radiated condenser in some time periods certainly, thereby, influenced the radiating effect of condenser.Dust also can be a large amount of descend slowly and lightly to condenser from the side direction louvre, and dust can corrode condenser and directly influence the radiating effect of condenser.

The case of known off-premises station all is to have adopted the iron plate of 0.8～1.5mm to make, and iron plate can absorb a large amount of solar thermal energies, and with the inside external radiation of ultrared mode, makes off-premises station case temperature inside higher, thereby, influenced the radiating effect of condenser.And dust also can a large amount of side direction descend slowly and lightly to condenser, and dust can corrode condenser and the direct radiating effect that influences condenser.

Along with the improvement of people's work, life, academic environment, the use amount of air-conditioning is also in a large amount of increases, and the loss of the minimizing power supply of effort not only helps environmental protection, has also alleviated the use burden of air conditioner user.

Three. technical problem and beneficial effect:

This case purpose: by improvement, make great efforts to improve the heat dissipation environment of case internal condensation device, save electrical source consumption with this to the off-premises station structure.Four. technical scheme:

The off-premises station of this case has adopted the structure of blocking solar thermal energy, thereby effectively suppresses radiation and the conduction of solar thermal energy to off-premises station.

Described structure of blocking solar thermal energy minimumly comprises or made up: condenser adopts vertical L shaped setting; Perhaps, the case side does not have louvre; Perhaps, case contain the venetian blind type louvre or, case contain thermal insulation layer or, case contains reflector layer.

In order to prevent the direct radiation of solar thermal energy, this case is improved to vertical L shaped setting with the horizontal L shaped setting of condenser, makes the lower portion of having changed to off-premises station near the fractional distilling tube of side.Because the lower portion of off-premises station only has a spot of outdoor unit base to block, the inner external empty saturating space of case has increased many, more because the heat that has strengthened between condenser and the case is transmitted space and distance, helps heat radiation.

The side of known case all has solar thermal energy can directly be radiated the louvre of condenser.

This case is improved to the vertical L of side-looking with condenser and is provided with, and the case side also keeps clear of condenser, so can select to make the case side not have louvre, has limited the outer hood shell of direct sunlight and direct-fired thermal current inlet chamber thereof.

Also can select the louvre that can look at condenser straight, change the venetian blind type louvre into case.The venetian blind type louvre not only can block solar thermal energy, and can block the dust that descends slowly and lightly, and helps improving the radiating effect of condenser.

Described venetian blind type louvre, its position, minimum comprising: the left side of case, right side, front, behind.

Known case all is to adopt iron plate to make, and can absorb many solar thermal energies, again can be to the many heat energy of internal radiation, and it is relatively poor that the metal case blocks the effect of solar thermal energy.

In order to suppress solar thermal energy, this case has designed the thermal insulation layer of case, in order to ensure the thermal insulation layer effect of heat insulation of case, will inevitably increase the aggregate thickness of case.The thermal insulation layer of described case is meant that the insulating materials aggregate thickness of case is 0.5～0.9mm, contain 0.9mm or, 0.9～1.3mm, contain 1.3mm or, 1.3～1.7mm, contain 1.7mm or, 1.7～2.1mm, contain 2.1mm or, 2.1～2.5mm, contain 2.5mm or,＞2.5mm.

The thermal insulation layer of described case, can select is the single layer structure that case adopts insulating materials fully; Perhaps, be that the table wall of insulating materials case contains metal level; Perhaps, be that the inwall of metallic plate case is or/and outer wall contains thicker insulating barrier.

The thermal insulation layer of described case, its material, minimum comprising: plastics, bakelite, epoxy resin, plastic-blasting, spray paint.

Because in the heat transfer type of solar thermal energy to off-premises station, heat radiation is main mode, in order to block the heat radiation of the sun, this case has increased reflector layer on the surface of case.The reflector layer of described case, the metal layer thickness that is meant the outermost layer of case or photic zone inside is＜0.15mm or, 0.15～0.3mm, contain 0.3mm or, 0.3～0.45mm, contain 0.45mm or, 0.45～0.6mm, contain 0.6mm or, 0.6～0.75mm, contain 0.75mm or, 0.75～0.9mm.

Described reflector layer can select to be arranged on the outermost layer of insulating materials case; Perhaps, increase the protective layer of similar varnish again at the outer wall of reflector layer.

The manufacture method of described reflector layer, minimum comprising: electroless plating, physics spraying, metal forming cover.

Five. embodiment:

Example 1 all is provided with the louvre of venetian blind type in the case side all around of metallic plate manufacturing.

Example 2, with the fixing stainless steel foil of 0.3mm thickness of the method for riveted, air inlet/outlet adopts the wire guard respectively on the surface of the epoxy resin board of 5mm thickness.

Example 3 is respectively arranged with the case surface of the ABS plastic of venetian blind type louvre in the left and right side, electroplate the metallic nickel of 9 μ m.The behind of case and positive air inlet/outlet, adding respectively has wire hood.

Example 4, Fig. 2, the surface of case front 1 and back 5 is provided with venetian blind type louvre 2 and 6 respectively, the condenser of case inside, upper end 13, lower end 14 is the vertical L shaped setting of side-looking, the front upper part position of condenser has electric fan 10 to block the solar thermal energy of front.

The above is only for referencial use, and unrestricted, can select 26S Proteasome Structure and Function according to actual needs and the otherwise combined application.This case exposes the change or the interpolation of member, not only has practicality, also can make things convenient for various people's operating habits and special requirement, has also brought new sensation to people, new visual effect.
