The invention provides a compressor device capable of automatically storing heat and quickly starting at low temperature, wherein a heat storage device is additionally arranged on the outer layer of a shell, a phase change material is filled in the middle, and heat absorption and release are realized by means of the state change of a liquid-solid phase change material, so that the temperature difference between the indoor space and the outdoor space is reduced, and the quick starting at the low temperature is further realized; the heat storage device adopts a corrugated pipe structure, and compared with a light pipe structure, the heat transfer area is large, and the heat storage capacity can be effectively improved.
The compressor is widely applied to household air conditioners, automobile air conditioners, heat pump water heaters and the like. The compressor is difficult to start under low temperature state, and the reason lies in when ambient temperature is very low, and the phenomenon of freezing can appear frosting outdoor compressor, leads to the inside refrigeration oil of compressor can be because of low temperature and solidify, can't lubricate compressor internal components and parts after the refrigeration oil solidifies, burns out the compressor easily.
The structure of the disclosure provides a compressor device capable of automatically storing heat and rapidly starting at low temperature, which comprises a heat accumulator made of a phase-change material, wherein the heat accumulator is tightly attached to the outside of a shell of the compressor; when the compressor does not work and the ambient temperature is lower than a certain value, the heat storage device releases energy, and the compressor is prevented from frosting and freezing due to the fact that the ambient temperature is too low.
Phase change materials, also known as latent heat storage materials, store or release heat energy by utilizing the property that a large amount of heat needs to be absorbed or released when a substance undergoes phase change (i.e., phase change enthalpy), thereby adjusting and controlling the ambient temperature around a working source or the material. In the phase change process from a solid phase to a liquid phase, when the temperature rises to the melting temperature of the phase change heat storage material, the phase change from the solid state to the liquid state is generated, and the phase change heat storage material absorbs and stores a large amount of latent heat; on the contrary, during the phase transition from the liquid phase to the solid phase, when the temperature is lower than the transition temperature of the phase-change material, a large amount of heat stored therein is released. The invention uses the heat absorption and discharge functions of the material to replace the prior electric heating belt preheating mode.
If no relative displacement occurs between parts of an object, the heat transfer caused by the thermal motion of microscopic particles such as molecules, atoms, and free electrons is called thermal conduction (also called heat conduction). The condition for heat transfer is that there is a temperature difference between the two parts of the system, where heat will be transferred from the high temperature part to the low temperature part, or from the high temperature object to the low temperature object in contact with it, until the parts of the whole object are at the same temperature. Heat conduction can occur in all solid, liquid and gas, but its micro-mechanism varies depending on the state of matter.
According to the heat quantity calculation formula Q, wherein A-heat transfer area, K-heat transfer coefficient and delta T-temperature difference, it can be seen from the formula that to increase the total heat transfer quantity, either the heat transfer contact area or the heat transfer coefficient is increased.

The inner layer is tightly attached to the shell of the compressor and made of aluminum alloy or stainless steel materials, and the material is large in heat transfer coefficient and can effectively transfer heat inside and outside the compressor. Furthermore, according to the law of thermal conductivity and thermal resistance, the thermal conductivity is unchanged, the smaller the thickness of the wall pipe is, the smaller the thermal conductivity and thermal resistance is, the larger the heat transfer coefficient is, and the preferable thickness of the inner layer is less than 1 mm. In order to further improve the heat transfer efficiency, the inner layer can be coated with a heat absorption coating.
The outmost layer of the heat accumulator is a corrugated pipe shell and made of heat insulation materials. Compared with the traditional light pipe, the corrugated pipe has the advantages that the concave-convex structure increases the heat transfer contact area with the air inside, and meanwhile, the corrugated pipe is compact in structure and can be discharged to more heat collecting pipes in unit volume. The presence of the relief structure allows a number of small spaces to be formed in the tube to suppress natural convection of air and thereby reduce heat loss. With the increase of the outer layer half arc R, hot air can form strong disturbance inside and outside the pipe, so that the heat transfer coefficient is greatly improved; however, if the half arc R is increased wirelessly, the pressure in the pipe is increased, the vortex strength is increased, the resistance is increased, and the heat transfer coefficient is reduced.
In some embodiments, the phase change material 51 is a solid-liquid phase change material that can undergo a solid-to-liquid phase or a liquid-to-solid phase change over the operating temperature range of the compressor. This is this disclosed phase change material's preferred structural style, can be adapted to compressor operating temperature scope, is in the temperature range that can normally work of compressor and the temperature range that can not normally start at low temperature range of crossing, can heat compressor shell inside through phase change material's freezing point automatic heat release when low temperature compressor can not normally start, guarantees the reliable continuous work of lubricating oil, and can heat phase change material when the compressor is higher than phase change material's freezing point and become liquid again to the deposit heat. The liquid-solid phase change material has a transition temperature of 20-30 ℃, such as higher aliphatic hydrocarbons, fatty acid or ester or salts thereof, or a multi-component organic heat storage material formed by combining several organic matters.
In some embodiments, the solid-liquid phase change material has a phase transition temperature in the range of 20 to 30 ℃. This temperature range can agree with the operating temperature range of compressor mutually, guarantees that the compressor can not the during operation through the exothermic automatic heating compressor casing of phase transition, and the compressor during operation can the heat absorption phase transition and the heat of storage.
The low-melting-point liquid-solid phase change heat storage material is preferably selected, the phase change temperature is 20-30 ℃, when the compressor works and operates, the temperature of the compressor is increased, and when the temperature is higher than 30 ℃, the phase change heat storage material is changed into a liquid state from a solid state, namely the phase change heat storage material is gradually melted, and the stored heat begins to accumulate; when the ambient temperature is reduced and the outside of the compressor begins to frost, the heat accumulated by the heat accumulator begins to be released, and the temperature difference between the inside and the outside of the compressor can be effectively reduced.
In some embodiments, the inner peripheral wall of the tube body 2 is a heat conductive layer 61, the outer periphery of the corrugated protrusions 3 is an insulating layer 62, and the phase change heat storage structure 5 is located between the heat conductive layer 61 and the insulating layer 62.

The intermediate layer is phase change material, and the compressor during operation carries out heat storage, and release heat preheats the compressor when ambient temperature is low.

The heat absorption coating is arranged on the outer layer of the heat conduction layer, so that the heat absorption capacity can be further improved, and the heat absorption efficiency is enhanced; the heat preservation skin still sets up the adiabatic coating and can further guarantee not outwards give off the heat, improves adiabatic efficiency, guarantees the heat accumulation ability of bellows structure.
The utility model mainly provides a three-layer temperature adjusting device that can be applied to compressor, temperature adjusting device size and compressor housing internal diameter, flange height have certain relation, guarantee to exert maximum temperature control ability in limited space, and the middle temperature adjusting pipe adopts special arrangement structure and encapsulation mode, encapsulates and designs the liquid-solid phase change material that latent heat energy is big but easy to leak, can solve the performance decay problem that the material leaks and leads to, improves greatly simultaneously and stores up, exothermal energy, reduces the temperature difference between compressor and the environment to improve the reliability of compressor.
In some embodiments, the thickness of the thermally conductive layer 61 is < 1 mm. According to the law of thermal conductivity and thermal resistance, the thermal conductivity coefficient is unchanged, the smaller the thickness of the inner-layer wall pipe is, the smaller the thermal conductivity and thermal resistance is, the larger the heat transfer coefficient is, so that the thickness of the inner layer is as small as possible to improve the heat transfer efficiency.
In some embodiments, the cross-sectional shape of the corrugated protrusion 3 is an arc having a radius R, and the inner diameter of the pipe body is D, and R is 1/10D, in a cross-sectional plane passing through the central axis of the pipe body 2. In a circle with the specified diameter D, if the half arc R of the outermost layer is infinitely increased, the resistance is overlarge when hot air circulates, and the heat transfer coefficient is reduced; therefore, R is set to be 1/10D, so that R cannot be too large, the internal hot air circulation resistance cannot be too large, and the heat transfer efficiency is improved.
The outer layer half arc R has a certain relation with the inner diameter D of the heat accumulator, and the half arc radius R in the corrugated outer layer is preferably 1/10D, so that the heat transfer energy is in the optimal state.
In some embodiments, the length of the bellows structure 1 in the direction of the central axis of the pipe body 2 is h1, the lower flange 7 is provided inside the housing 4, and the length of the lower flange 7 in the central axis is h lower flange +1mm, and h1 ═ h lower flange. The heat accumulator mainly heats the refrigeration oil in the compressor, the addition amount of the refrigeration oil is empirically referred to by the fact that the oil liquid level is immersed on the upper end face of the upper flange when the refrigeration oil is static, therefore, in the whole pump body part, the part which is completely immersed in the oil pool and occupies the highest oil amount is the lower flange, the corrugated temperature adjusting structure mainly adjusts the temperature of the oil pool of the compressor, the part is interfered with the air suction pipe 9 of the compressor too high and is not beneficial to installation, the part is too low and cannot collect and release more heat, and the temperature adjusting effect is not good; therefore, the heat absorption amount and the heat release amount of the bellows structure to the casing can be ensured in the range, and the bellows structure can not be interfered with the air suction pipe.
In some embodiments, the phase change heat storage structure 5 further includes a first receiving portion 52, and the phase change material 51 is received in the first receiving portion 52; the phase change thermal storage structure 5 further includes a second receiving portion 53, the number of the first receiving portions 52 is at least one, and at least one of the first receiving portions 52 is received in the second receiving portion 53. The phase change material can be contained in the first containing part, leakage caused by volume change of the phase change material due to phase change is effectively prevented, the first containing part can be contained in the second containing part, and the heat exchange area can be increased. The second receptacle is preferably a tempering tube.
In some embodiments, the first container 52 has a capsule shape, and the phase change material is encapsulated in the first container 52 by an encapsulation method; and/or the second accommodating part 53 has a straight circular tube structure, the second accommodating parts 53 are multiple, and the arrangement form of the multiple second accommodating parts 53 is trapezoidal, S-shaped or M-shaped.
The temperature adjusting pipe is filled by microcapsule accumulation, the structure can solve the influence of volume change caused by phase change state change and prevent phase change material from leaking, and the structure has large surface area and can provide higher heat transfer area. In order to increase the heat storage capacity and increase the number of the intermediate heat collecting pipes as much as possible, a trapezoidal arrangement structure or other structures such as S, M are preferred, and more intermediate heat collecting pipes can be ensured to be arranged in the same unit area. The temperature adjusting pipes are arranged in a trapezoidal shape or in an S, M-shaped structure, namely, more temperature adjusting pipes can be arranged in a unit half arc area, and other structural forms can also be used.
The phase-change material can perform liquid-solid transition according to the change of temperature, the volume change can occur to cause leakage, the microcapsule sealing is performed, and the macro-phase material is solid, so that the leakage phenomenon when the phase-change material is changed into liquid can be prevented.
The temperature regulating tube is formed by stacking a plurality of small microcapsules, and the surface area is the sum of the areas of all the microcapsules, so that the surface area is effectively increased.
And a middle filling layer between the inner layer and the outer layer of the heat accumulator is a temperature adjusting pipe, and a liquid-solid phase change heat accumulation material is packaged in the middle of the temperature adjusting pipe. When the compressor works, the temperature of the pump body is close to 100 ℃, at the moment, the heat of the compressor is firstly absorbed by the heat absorption coating of the inner layer through the shell, then is transmitted to the middle temperature adjusting pipe through the aluminum inner layer, and then is absorbed by the phase-change material in the temperature adjusting pipe, when the temperature exceeds the phase-change transition temperature, the material undergoes phase-state transition, starts to accumulate heat, and is blocked by the outer-layer heat-insulating material in order to avoid heat loss.
In some embodiments, when the external shape of the first container portion 52 is a capsule shape, the capsule wall of the first container portion 52 is a high molecular polymer. The high molecular polymer serving as the capsule wall (the wall of the first accommodating part) can not react with the internal phase-change material, and has certain strength and toughness, so that the effective encapsulation effect on the phase-change material can be realized.
In order to improve the heat storage capacity of the phase-change material, the phase-change material is sealed by adopting a microcapsule packaging method, the method can effectively solve the influence caused by volume change when the state of the material is changed, and can also increase the contact surface area and improve the heat transfer capacity. The core of the capsule is made of phase-change heat storage materials, and the capsule wall is made of high polymer materials for encapsulation, so that the capsule has a good heat insulation effect and does not react with the core materials.
The structure of the liquid-solid phase change material capsule adopts a special liquid-solid phase change material, can solve the leakage problem during liquid-solid phase change through capsule packaging, and improves the heat storage and release capacity through a plurality of special vertical accumulation and arrangement forms.
In some embodiments, the corrugated protrusions 3 are plural and are arranged at intervals along the central axis of the pipe body 2; the distance between two adjacent corrugated protrusions 3 along the central axis of the pipe body 2 is h2, the length of the corrugated pipe structure 1 in the central axis direction of the pipe body 2 is h1, and h2 is h 1/2-h 1/3.
