Detailed Description

The cavity type energy-exchanging radiation air conditioner terminal provided by the invention is explained and explained in detail with the attached drawings of the specification.

As shown in fig. 1 and 2, the present embodiment specifically discloses a cavity type transduction radiation air conditioning terminal, which includes: the cavity type energy conversion layer 1 comprises a first component 11 and a second component 12, the first component 11 and the second component 12 enclose a cavity, a first main flow path 3, a second main flow path 4 and a plurality of branch flow paths 5 connected in parallel are arranged in the cavity, the first main flow path 3 is parallel to the second main flow path 4, the first main flow path 3 and the second main flow path 4 are arranged at two ends of the branch flow paths 5, and the first main flow path 3 and the second main flow path 4 are communicated with the branch flow paths 5. After entering the cavity, the liquid of the cold source or the heat source flows through the parallel channels formed by the plurality of branch flow paths 5, the first main flow path 3 and the second main flow path 4, and flows through the whole cavity to transfer heat. The radiant heat is more uniform, so that the temperature of the radiant surface is more uniform, the low-temperature area is prevented from being formed, and the risk of condensation is reduced. And a plurality of branch flow paths 5 are connected in parallel, so that compared with a series long-stroke fluid channel, the fluid resistance is reduced, the energy consumption is reduced, and the heat transfer is more uniform.

The plurality of branch channels 5 may be perpendicular to the first main channel 3 and the second main channel 4, or may form a certain angle with the first main channel 3 and the second main channel 4 (that is, the branch channels 5 are obliquely provided between the first main channel 3 and the second main channel 4). Preferably, the plurality of branch flow paths 5 are perpendicular to the first main flow path 3 and the second main flow path 4.

The utility model discloses a plurality of flow paths 5 form through the protruding stupefied 6 of a plurality of parallels, and the interval between the adjacent protruding stupefied 6 makes liquid can flow wherein for a flow path 5, and the both ends of protruding stupefied 6 and the limit of the second component 12 of first component 11 are apart from a certain distance, and this distance is the width of first main flow path 3 and second main flow path 4. The convex edge 6 can be in a linear or arc shape, and can also be assisted by a convex column-shaped structure. The intervals between the ridges 6 may be the same or different, that is, the widths of the plurality of branch flow paths 5 may be the same or different. The ridge 6 may be provided only on the first member 11; or may be provided only on the second member 12; it is also possible to arrange the first member 11 partially and the second member 12 partially, so that when the first member 11 and the second member 12 are joined together, a complete flow path is formed for the liquid to flow through the entire chamber. The convex edge 6 is integrally formed with the member where it is located or fixedly connected in other ways, preferably integrally formed. The convex edge 6 has the first function of forming a branch flow path 5 to guide the fluid in the cavity to flow throughout the whole cavity as uniformly as possible; the convex edge 6 has the secondary function of improving the structural strength of the cavity.

The first member 11 and the second member 12 are surrounded by a sealing strip. The sealing strip can not only play sealed effect, can separate the inside liquid of cavity and outside air moreover, avoids indoor air and transduction layer direct contact to cause the dewfall.

The calculation formula of the thermal resistance is as follows: the thermal resistance R is d/lambda; wherein d is the material thickness; regarding the thermal conductivity λ: according to the fourier law of thermal conductivity, when the heat transfer element is a single-layer flat plate with a thickness dx and the two sides of the heat transfer element are maintained at uniform and constant temperatures t1 and t2, Q ═ λ × a (t1-t2)/dx represents the heat transfer amount, and a represents the area of the heat transfer element.

In some embodiments, the first member 11 and the second member 12 are made of the same material and have the same thickness, that is, the thermal resistances of the first member 11 and the second member 12 are the same, the first member 11 and the second member 12 are integrally formed or spliced, and a third structural layer having a thermal resistance different from that of the cavity type energy conversion layer 1 is disposed on one or both sides of the cavity type energy conversion layer 1.

When the third structural layer is arranged on one side of the cavity type energy conversion layer 1, more heat is conducted on one side of the cavity by using heat. If the thermal resistance of the third structural layer is greater than the thermal resistance of the first member 11 and the second member 12, the third structural layer is a thermal insulation layer, and heat is conducted to the surface far away from the third structural layer more, so that the radiation efficiency is improved. In this case, a radiation panel may be added to the cavity type energy conversion layer 1 on the side away from the third structural layer, or a member of the energy conversion layer away from the third structural layer may directly serve as a radiation surface to radiate heat.

When the third structural layers are arranged on both sides of the cavity type energy conversion layer 1, the use requirement of double-sided radiation is met, for example, when the cavity type energy conversion layer is used as a vertical ceiling hanging plate or a screen type radiation air conditioner terminal, the heat resistance of the first component 11 and the second component 12 is the same, and the heat radiated to both sides by the energy conversion layer is the same. The third structural layer can be a radiation panel or a combination of a sound attenuation layer and the radiation panel, the specific form of the third structural layer is not specially limited, and the third structural layer can be set by a person skilled in the art according to actual needs, so that the tail end of the radiation air conditioner is of a structure with two completely symmetrical sides to perform double-sided radiation.

The first member 11 and the second member 12 are made of the same material, that is, the first member 11 and the second member 12 have the same thermal conductivity. The first member 11 and the second member 12 are preferably integrally formed during processing, so that the consistency and the quality stability of the end product of the radiation air conditioner are improved, the cost of the end of the radiation air conditioner is greatly reduced, and the product yield is further improved.

In some embodiments, the first member 11 and the second member 12 are made of the same material (with the same thermal conductivity) and have different thicknesses, and based on the relationship between the thermal resistance and the thermal conductivity and thickness, the thermal resistance of the first member 11 and the thermal resistance of the second member 12 are different, and the first member 11 and the second member 12 are integrally formed or spliced. If the thermal resistance of the first component 11 is greater than that of the second component 12, the first component 11 with the greater thermal resistance serves as a thermal insulation layer, the second component 12 with the lesser thermal resistance serves as a thermal damping layer, and more heat is radiated to one side of the thermal damping layer. The thermal damping layer can be directly used as a radiation surface, a radiation panel can be arranged on the outer side of the thermal damping layer, or a radiation coating with high emissivity is laid on the thermal damping layer. The heat insulation layer and the thermal damping layer form asymmetric heat transfer, heat is transferred to one side of the thermal damping layer more, and the thermal damping layer enables the radiation heat to be more uniform, so that the anti-condensation effect is achieved.

In some embodiments: the first member 11 and the second member 12 are made of different materials, that is, the first member 11 and the second member 12 have different thermal resistances, and the first member 11 and the second member 12 have different thermal resistancesThe two members 12 are integrally formed or joined. The first member 11, e.g. as a thermal barrier, is made of a thermal resistance>0.1m²K/W material composition, e.g. thickness>2mm, coefficient of thermal conductivity<0.02W/mK, preferably rigid plastic or foam molding material molded by a mold; the second member 12 as a thermal damping layer is composed of a thermal resistance<0.1m²K/W, e.g. thickness not exceeding 2.5mm, thermal conductivity>The non-metallic material of 0.02W/mK is preferably XPS extruded sheet (extruded polystyrene foam plastic board), EPS polystyrene board (expanded polystyrene board), polyurethane board, etc.

The cavity type energy conversion layer 1 is provided with a radiation panel at one side close to the component with lower thermal resistance, namely, the other side of the second component 12 is tightly attached to the radiation panel. Alternatively, the outer surface of the member with lower thermal resistance in the first member 11 and the second member 12 is coated with a radiation coating, that is, the outer surface of the second member 12 is coated with a radiation coating as a radiation surface. Taking summer working conditions as an example, chilled water at the temperature of 8 ℃ to 18 ℃ is injected into the cavity, and as the thermal resistance of the thermal insulation layer is high and the thermal resistance of the thermal damping layer is low, more heat can be transmitted into the cavity from one side of the thermal damping layer, and then is taken away through the liquid outlet 8 after being absorbed by the chilled water.

The function of the thermal damping layer is illustrated below:

as shown in fig. 4a, the thermal damping layer 22 is not provided, and the heat conducting layer 21 (the transduction layer here refers to the heat source or the heat source liquid) is directly in contact with the radiation panel 23; due to the lack of y-direction heat conduction by the thermal damping layer 22, the isotherm T4 of the radiating panel 23 is more curved, i.e., the surface temperature difference is greater.

As shown in fig. 4b, a thermal damping layer 22 is provided between the heat conductive layer 21 and the radiation panel 23; according to the fourier heat conduction law, in the isotropic thermal damping layer 22, if heat enters the interior of the thermal damping layer 22 from the thermal conduction layer 21, since there is a temperature gradient in both x and y directions near the left side (the isotherm shows a curve in the x-y section), the direction in which the temperature gradient is the largest, and the passing heat flow density q is also the largest. Due to the integral accumulation effect, it can be calculated that: when the heat reaches the right boundary of the thermal damping layer 22, the isotherm tends to be flat, i.e., the temperature at the right boundary of the thermal damping layer 22 tends to be uniform. The isotherm T4 of the radiation panel 23 is flatter.

Therefore, the thermal damping layer enables the radiation heat to be more uniform and the radiation effect to be better.

The first member 11 and the second member 12 enclose a cavity, so that the preparation process is reduced, the first member 11 and the second member 12 can be directly integrally formed into the cavity in a die forming mode, or the first member 11 and the second member 12 are respectively spliced into the cavity after die forming, the consistency and the quality stability of a product at the tail end of the radiation air conditioner are improved, the tail end cost of the radiation air conditioner is greatly reduced, and the product yield is further improved.
