Description

Technical Field

[0001] This utility model relates to the field of solar heating and thermal insulation technology, and in particular to a novel insulated device for solar collectors. Background Technology

[0002] The Composite Parabolic Concentrator (CPC) type heat pipe vacuum tube collector is a new type of medium-temperature solar thermal collector. The efficiency of a solar collector is determined by the following factors: 1. The size of the collector's light-gathering capacity; 2. The amount of heat loss due to insulation. The solar glass tube serves as both the light-gathering and heat-transporting device in the solar collector.

[0003] The glass tube is the main heat energy concentration area of ​​the solar collector, with high-temperature air circulating inside. The outside of the solar tube is in contact with the environment, so the internal temperature is relatively high. In the frigid northern regions, the air temperature is low, and the outdoor ambient temperature is also low. The temperature difference between the two is large, resulting in significant heat loss. The exposed glass tube has a large contact area, so its thermal insulation directly affects the solar collection efficiency.

[0004] The current method for insulating glass collector tubes is to wrap the glass tube with insulation materials such as rock wool, aluminum silicate, or blankets, and then wrap a layer of galvanized iron sheet or aluminum foil tape over the insulation material. This reduces heat loss from the collector tube and extends its lifespan.

[0005] The applicant has discovered at least the following technical problems in the existing technology: the existing glass tube insulation structure has the disadvantages of mediocre insulation effect, low production efficiency, poor quality, complicated construction, large amount of engineering work, short life and poor aesthetics. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of insulated device for solar collectors to solve the technical problems of complex construction of insulation structures, large amount of engineering work, and general insulation effect in the existing technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides a novel insulated device for solar collectors, comprising an insulation shell and a locking component; wherein:

[0009] The insulation shell is a split structure, consisting of a hollow semi-circular first insulation half-shell and a second insulation half-shell;

[0010] When the first insulation half-shell and the second insulation half-shell are joined together, they can cover the pipe to be insulated.

[0011] The locking element is located on the outside of the insulation shell to lock it in place after it is wrapped.

[0012] The novel solar collector insulator device provided by this utility model features a split semi-circular insulation shell that can be directly connected and wrapped around the outside of the pipe to be insulated during installation. It is then locked in place using locking components, simplifying the installation process, reducing labor intensity, and improving work efficiency.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] As a further improvement of this utility model, it also includes a snap-fit ​​structure disposed between the first insulation half-shell and the second insulation half-shell.

[0015] By setting a snap-fit ​​structure between the two half-shells, it is easy to snap and fix the two half-shells together. This not only facilitates the installation of subsequent locking parts, but also enables quick installation of the half-shells. Furthermore, the snap-fit ​​edge and the snap-fit ​​groove are not exposed after assembly, and are integrated into one piece, improving the aesthetics.

[0016] As a further improvement of this utility model, the snap-fit ​​structure includes a snap-fit ​​groove disposed on both ends of the first insulation half shell and a snap-fit ​​edge disposed on both ends of the second insulation half shell; the snap-fit ​​edge is adapted to the specifications of the snap-fit ​​groove.

[0017] With its slot and edge-locking structure, the edge-locking mechanism is inserted into the slot during installation, which not only guides and positions the two half-shells for installation but also enables rapid assembly and splicing, simplifying the installation process and increasing installation efficiency. Furthermore, this type of snap-locking structure is easy to process.

[0018] As a further improvement of this utility model, the slot is located on the inner side of the end face of the first heat-insulating half shell.

[0019] By setting a slot on the inside of the first insulation half-shell, the locking edge is also located on the inside of the second insulation half-shell. This structure allows the locking structure to have a certain limiting effect when they are locked together.

[0020] As a further improvement of this utility model, the cross-section of the slot is rectangular or square.

[0021] Rectangular or square slots are used, which are easy to process and have a certain strength to prevent damage during snapping.

[0022] As a further improvement of this utility model, both the first and second insulated half-shells include an outer protective layer and an inner insulation layer; the outer protective layer and the inner insulation layer are integrally processed.

[0023] By setting an insulation layer on the inside of the half-shell and a protective layer on the outside, not only is heat preservation achieved, but lifespan is also increased and service time is extended.

[0024] As a further improvement of this utility model, the protective layer is made of a material with good UV resistance, corrosion resistance, weather resistance and wind and sand resistance.

[0025] As a further improvement of this utility model, the outer protective layer is made of PVC material.

[0026] By selecting the above materials, thermal insulation of the solar CPC collector can be achieved, improving the collector's photothermal conversion efficiency and extending its service life.

[0027] As a further improvement of this utility model, the inner insulation layer is made of polyurethane material.

[0028] By using polyurethane foaming technology, the outer protective layer and the inner insulation layer are processed together as a single unit, so that its structure and appearance are perfectly integrated with the solar CPC collector. Prefabrication ensures quality, aesthetic appearance, and low installation cost.

[0029] As a further improvement of this utility model, the two ends of the heat-insulating shell have a tapered structure.

[0030] This structural design allows for a better fit to the beveled ends of the pipe to be insulated.

[0031] As a further improvement of this utility model, the locking component includes a hose clamp.

[0032] The two halves of the shell are locked together using a hose clamp, which is easy to operate.

[0033] As a further improvement of this utility model, the number of hose clamps is several, which are spaced apart along the axial direction of the insulation shell.

[0034] This invention is based on polyurethane foaming technology and combines it with the structural design of solar CPC collectors to solve the problems of poor insulation at the joints, poor appearance quality, and short lifespan of solar CPC collectors. By employing a pre-fabricated foaming insulation process, the insulation structure and appearance are designed to perfectly integrate with the solar CPC collector. A PVC pipe is used as the outer protective layer, symmetrically cut into two parts for on-site assembly. Assembly is simple, aesthetically pleasing, and highly efficient. Furthermore, materials suitable for outdoor use (UV resistance, corrosion resistance, weather resistance, and wind and sand resistance), such as PVC, are selected. Its high-temperature resistance reaches 120℃, achieving a long lifespan. This device overcomes the aforementioned shortcomings and has broad application prospects. Attached Figure Description

Moreover, the snap-fit ​​structure 2 of this type is easy to process.

[0051] As a further improvement of this utility model, the slot is located on the inner side of the end face of the first heat-insulating half shell 11.

[0052] By setting a slot on the inner side of the first insulation half-shell 11, the locking edge is also located on the inner side of the second insulation half-shell 12. This structure allows the locking structure 2 to have a certain limiting effect when they are locked together.

[0053] As a further improvement of this utility model, the cross-section of the slot is rectangular or square.

[0054] Rectangular or square slots are used, which are easy to process and have a certain strength to prevent damage during snapping.

[0055] As a further improvement of this utility model, both the first insulating half-shell 11 and the second insulating half-shell 12 include an outer protective layer 111 and an inner insulating layer 112; the outer protective layer 111 and the inner insulating layer 112 are integrally processed.
