Abstract
The utility model discloses a heat preservation sleeve structure which comprises a hollow inner cavity, an outer wall and a foamed insulating layer between the inner cavity and the outer wall. The foamed insulating layer is integrated with the outer wall. The foamed insulating layer is formed by two or more layers. A plurality of hollow cavities are regularly arranged inside each layer of the foamed insulating layer. Two hollow inner cavity layers are designed in the heat preservation sleeve disclosed by the utility model, so that sound waves in various frequency ranges can be greatly weakened, the noise is reduced and the sleeve simultaneously has functions of preserving heat and reducing noise.
Description
Technical field
The utility model relates to a kind of thermal insulation casing structure of on the air conditioner indoor and outdoor machine tube connector, using.
Background technology
Air-conditioner is a kind of household appliances that extensively are used, and mainly is made up of evaporimeter, condenser, throttling arrangement, compressor four major parts, couples together through pipeline between each parts, and refrigerant is flow at high speed therein, forms a refrigeration system efficiently.Split-type air conditioner comprises off-premises station and indoor set, and compressor, condenser are set in the off-premises station, and indoor set mainly contains evaporimeter, and throttling arrangement connects condenser and evaporimeter; Between off-premises station and indoor set, need tube connector to be connected, behind the operation of air conditioner, refrigerant is flow at high speed in pipe; Longer because of tube connector, on-way resistance is bigger, and energy loss is a lot; In order to improve the utilization ratio of energy, need increase one deck heat-insulation layer at the tube connector outer surface, reduce the loss of energy.Simultaneously, because this tube connector connects indoor set, its noise reduction also there is certain requirement.What heat-insulation layer commonly used was at present taked is PE foaming or rubber-plastic foamed thermal insulation casing.Polyethylene (PE) foamed heat insulating sleeve pipe is non-cross-linked type polyethylene (PE) foamed plastics; With low density polyethylene (LDPE) (being called for short LDPE) is base material; Add various additives; Prevent agent like nucleator, incombustible agent, blowing agent, Masterbatch, contraction, the elasticity adiabatic heat-insulation sleeve pipe that the physical blowing method of directly extruding processes with hole-closing structure.Rubber-plastic foamed thermal insulation casing; Be that mixture with natural or synthetic rubber and other high-molecular organic material (like polyvinylchloride) is a base material; Be aided with necessary additive; Like age resister, fire retardant, stabilizing agent, vulcanization accelerator, blowing agent etc., through banburying, mixing, extrusion foaming and cooling and shaping, the elasticity adiabatic heat-insulation sleeve pipe that processes with hole-closing structure.The structure of thermal insulation casing is shown in Fig. 1-2; At present, more than two kinds of sleeve pipes all have good heat insulation effect, other sqouynd absorption lowering noise effect but very a little less than; Can not weaken each frequency range sound wave effectively significantly; Air-conditioning indoor and outdoor machine tube connector noises such as fluorine stream sound still can occur after using thermal insulation casing, is difficult to satisfy the requirement of client responsive to the air-conditioner noise.
The utility model content
In order to solve the technical problem of above-mentioned existence, the utility model purpose provides a kind of not only can be incubated but also have the thermal insulation casing structure of decrease of noise functions, to overcome the deficiency of prior art.
The technical scheme that the utility model adopts is: the thermal insulation casing structure; The inner chamber, outer wall, the insulating foam layer between inner chamber and outer wall that comprise hollow; Said insulating foam layer and outer wall are integrated; Said insulating foam layer constitutes more than two-layer or two-layer, and rule is provided with a plurality of hollow die cavities in each layer.
Said insulating foam layer comprises internal layer and skin, and the hollow die cavity dislocation of said ectonexine is arranged.
Said hollow die cavity is a cylinder, the center of circle of cylindrical orientation of its axis place thermal insulation casing cross section.
Said heat-insulation layer is processed by non-crosslinked type polyethylene foams or rubber plastic foam material foaming.
The beneficial effect of the utility model is: owing to be designed with two-layer hollow cavity layer in the thermal insulation casing, can weaken each frequency range sound wave significantly, reduce noise, make sleeve pipe have the function of insulation and noise reduction simultaneously.

The specific embodiment
Detachable air conditioner needs thermal insulation casing to keep the low-temperature condition of the inner refrigerant of indoor and outdoor machine tube connector, reaching the normal operation of refrigeration system, and reduces the loss of the energy with this, obtains energy-conservation effect.The utility model has the effect of insulation and noise reduction simultaneously in order to make thermal insulation casing; On the structure of insulating foam layer, make improvement; Like Fig. 3 and shown in Figure 4, thermal insulation casing comprises inner chamber, outer wall, the insulating foam layer between inner chamber and outer wall of hollow, and wherein insulating foam layer and outer wall are integrated; Insulating foam layer is made up of with outer 2 internal layer 1, and rule is provided with a plurality of hollow die cavities in each layer.Hollow die cavity at ectonexine is that cylinder and dislocation are arranged.Hollow die cavity isometric circle week distributes, and is the form of putting that crouches, the center of circle of its orientation of its axis place thermal insulation casing cross section.Insulating foam layer is processed by non-crosslinked type polyethylene foams or rubber plastic foam material foaming.
When sound wave imports thermal insulation casing into; Arrive the internal layer of thermal insulation casing earlier; Because of this layer a plurality of columniform hollow die cavity that is being equally spaced, the air in the cavity is different with the insulating foam layer acoustic impedance, and sound wave can constantly come back reflective at the inner surface of cavity; Be gradually transformed into thermal dissipation and fall, sound wave is constantly weakened.Then, sound wave imports skin into, and this insulating foam layer many columniform hollow die cavities that also are being equally spaced, sound wave are weakened once more significantly.In addition, this thermal insulation casing material is PE foaming or rubber-plastic foamed, is a kind of sound-absorbing material; No matter the sound wave of the thermal insulation casing through the utility model is high frequency, still in, low frequency; All will be weakened step by step, the noise that passes to indoor set from off-premises station will reduce significantly, and drone noise is effectively eliminated; Tonequality improves, and the erasure effect highly significant can satisfy the high request of client to the air-conditioning noise quality.
The thermal insulation casing of the utility model has many functions such as insulation, waterproof mildew-resistant, anti-frosting condensation, sound insulation noise elimination, vibrationproof buffering, can be widely used in fields such as industry, construction, agricultural, cooling channel, hot water supply.
