Technical field

The utility model belongs to central air-conditioning energy technical field, more particularly, to a kind of guarantor for central air conditioner system Incubator body.

Background technique

Central air conditioner system is made of one or more cold and heat source systems and multiple air handling systems, which is different from Traditional cryogen formula air-conditioning, (such as uniset, VRV) air centralized processing have reached comfort requirement；The original freezed using liquid gasification Reason provides institute's chilling requirement for air handling system, to offset the refrigeration duty of indoor environment；Heating system is air handling system Institute's calorific requirement is provided, to offset indoor environment thermic load.

However as social development, energy shortages is increasingly apparent, and the energy consumption for effectively reducing air-conditioning is imperative, however passes The poor thermal insulation property of the cabinet of the central air-conditioning of system, and intensity is lower, under stress can deformation occurs, be easy to leak out, it is easily generated Cold bridge.

Utility model content

The utility model for overcome the deficiencies in the prior art, provides a kind of high intensity, low drain wind, in being used for of disconnected cold bridge Entreat the thermal-insulating body of air-conditioning system.

To achieve the goals above, the utility model uses a kind of following technical scheme: guarantor for central air conditioner system Incubator body, including inner wall, the outer wall with heat insulation effect and the interconnecting piece for connecting the outer wall and the inner wall；The company Socket part includes the first clamping portion and the second clamping portion for matching with first clamping portion；By the setting of inside and outside wall, increase While cabinet intensity, the effect of heat preservation is also functioned to, to reduce the energy consumption of air-conditioning；First connecting portion and second connecting portion Setting then play the role of reinforcing body structure intensity avoiding cabinet from leaking out to reduce the deflection of cabinet.

Further, first clamping portion is equipped with card slot, and second clamping portion is equipped with to match with the card slot The buckle protrusion of conjunction；By the setting of above structure, so that the connection of cabinet is more secured and close, playing prevents box deformation Wind action is leaked, and the service life is longer.

Further, the interconnecting piece is aluminum alloy framework；The inner wall is made of galvanized sheet；The outer wall is color steel plate It is made；Aluminum alloy framework intensity is higher, guarantees the intensity at cabinet angle seam；Inner wall made of galvanized sheet then plays preferable anti- Corrosiveness, so that the service life is longer for cabinet；And outer wall made of color steel plate then plays reduction weight, heat-insulated guarantor The effect of temperature, and intensity is higher, is not easy deformation.

Further, the first connecting portion is connected by a bolt with the second connecting portion；Easy for installation, structure is strong Du Genggao.

Further, the thermal-insulating body further includes the filled layer for being close to the outer wall setting, is close to the inner wall setting Thermal insulation layer and the insulating layer that is affixed with the thermal insulation layer, the filled layer, the inner wall and the interconnecting piece；By above-mentioned The setting of structure greatly reduces the heat exchange between inside and outside cabinet, to play section so that the heat insulation effect of cabinet is preferable The effect of energy emission reduction.

Further, the filled layer is at least partly embedded in the interconnecting piece, the filled layer and the thermal insulation layer It is connected；By the setting of above structure, enables filled layer to play better seal leak stopping, fills a vacancy and squeegee, fix bonding, heat preservation The effect of sound insulation.

Further, the thermal insulation layer is made of vacuum heat-insulating plate, which is filling core material and vacuum protection Surface layer is combined；It is effectively prevented from the transmitting of heat caused by cross-ventilation, therefore thermal coefficient can be greatly lowered, and be less than 0.007W/m·k。

Further, the insulating layer is made of PE heat-preservation cotton, and multiple subtle independent air bubbles are equipped in the PE heat-preservation cotton； It can effectively reduce energy exchange caused by cross-ventilation.

Further, sealing is equipped between adjacent two inner walls；For the sealing at cabinet vertical joint, so that case The junction sealing effect of body is good, and then ensure that the heat insulation effect of cabinet.

Further, irony reinforcing rib is removably connected on the interconnecting piece；It plays and reinforces body structure intensity Effect.

In conclusion setting of the utility model by inside and outside wall also functions to heat preservation while increasing cabinet intensity Effect, to reduce the energy consumption of air-conditioning；It is strong that the setting of first connecting portion and second connecting portion then plays reinforcement body structure The effect of degree avoids cabinet from leaking out to reduce the deflection of cabinet.
