Description

Technical Field

[0001] The utility model belongs to the technical field of water heaters, in particular to a heat collector. Background Art

[0002] A solar thermal collector is a device that converts solar radiation into heat and is a key component of various solar energy-utilizing devices. It absorbs solar radiation and transfers the resulting heat to a heat transfer medium, such as water or air, for subsequent use.

[0003] The basic principle of solar thermal collectors is energy conversion, similar to the principles of mulch films and greenhouses. They utilize the greenhouse effect to convert solar radiation into heat. Sunlight consists of visible and invisible light of varying wavelengths, and different materials and colors absorb and reflect different wavelengths differently. Black absorbs sunlight most strongly, making it a suitable color for heat collection. Heat can also be collected by focusing parallel sunlight onto a point, a line, or a small area through a focusing lens.

[0004] Because solar energy is relatively dispersed, it must be concentrated in a way. Therefore, the collector structure is a key component of various solar energy devices. Due to different uses, the collector structure and its matching system types are divided into many types, with different names, such as solar cookers for cooking, solar water heaters for producing hot water, solar dryers for drying items, solar furnaces for smelting metals, as well as solar houses, solar thermal power stations, solar desalination devices, etc. The collector structure is a major component, but when the collector structure is used in demanding scenarios, the heat collected by the collector is large, and the materials used to make the collector structure will deform due to the characteristics of thermal expansion and contraction and pressure. The various materials used to make the collector have different variables at high temperatures, which may cause damage to the collector and waste materials. The main reason is that it cannot operate under pressure. Utility Model Content

[0005] In order to solve the problem of damage to the heat collector and serious waste of materials caused by the limited pressure bearing capacity of the heat collector, the utility model provides a heat collector capable of improving the pressure bearing capacity of components.

[0006] The utility model is realized through the following technical solutions:

[0007] A heat collector comprises a header shell, the header shell is filled with insulation material, an inner flow tube and a connecting tube made of metal are arranged in the insulation material, a plurality of connecting tubes are provided, and the plurality of connecting tubes are evenly distributed along the length direction of the inner flow tube, and one end of the connecting tube is connected to the inner flow tube, and the other end passes through the insulation material and extends to the outside of the header shell, and a quick connector made of metal is provided at the end of the connecting tube extending to the outside of the header shell.

[0008] By using metal materials for pipe fittings, the ability to neutralize the thermal expansion and contraction of the material caused by temperature changes is improved. At the same time, the quick connector made of metal on the outside of the junction box shell is used to connect it to the collector pipe, thereby improving the ability to withstand pressure and reducing the risk of collector damage and material waste.

[0009] A further improvement of the present invention is that the length direction of the above-mentioned inner flow tube is distributed along the length direction of the header shell, and the two ends of the inner flow tube extend to the outside of the header shell respectively. The end of the inner flow tube extending to the outside of the header shell is provided with an external thread joint made of metal, and a sealing part is detachably installed on the external thread joint.

[0010] A further improvement of the present invention is that shell end covers are provided at both ends of the header shell in the length direction.

[0011] A further improvement of the present invention is that an end cover dust ring is provided on the outside of the shell end cover and is sleeved on the inner flow tube. The end cover dust ring seals the gap between the inner flow tube and the shell end cover.

[0012] A further improvement of the present invention is that a heat collecting tube dust ring is provided on the outside of the header shell and is sleeved on the connecting tube. The heat collecting tube dust ring seals the gap between the connecting tube and the header shell.

[0013] A further improvement of the present invention is that the above-mentioned thermal insulation material is a polyurethane foam material.

[0014] A further improvement of the present invention is that a partition can be welded inside the inner flow tube.

[0015] It can be seen from the above technical solution that the beneficial effects of the utility model are: the pipe fittings are made of metal material to improve the ability to neutralize the thermal expansion and contraction of the material caused by temperature changes. At the same time, they are connected to the heat collecting pipe with the help of a quick connector made of metal material on the outside of the junction box shell, thereby improving the pressure-bearing operation capability and the convenience of assembly, and reducing the high risk of damage to the collector.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0022] Example 1:

[0023] As attached Figure 1-3As shown, a heat collector comprises a header housing 1, with housing end caps 2 provided at both ends of the header housing 1 in its longitudinal direction. The housing end caps 2 and header housing 1 can be constructed of stainless steel or brushed corrosion-resistant materials. The separate assembly of the housing end caps 2 and header housing 1 facilitates the placement of internal pipes and improves the aesthetics and structural strength of the overall exterior shell. The space enclosed by the header housing 1 and the housing end caps 2 is filled with insulation material 3, which is polyurethane foam. As a polymer, the polyurethane foam provides insulation for the pipes and provides support and fixation for the pipes within the space. The insulation material 3 is provided with a metal inner flow tube 4 and a connecting tube 7. There are multiple connecting tubes 7, which are evenly distributed along the length of the inner flow tube 4. One end of the connecting tube 7 is connected to the inner flow tube 4, and the other end passes through the insulation material 3 and extends to the outside of the header shell 1. The end of the connecting tube 7 extending to the outside of the header shell 1 is provided with a metal quick connector 8. The quick connector 8 is a threaded structure that can be threadedly connected to the heat collecting tube, or it can be a structural member that can be quickly connected to the heat collecting tube. The outside of the header shell 1 is provided with a heat collecting tube dust ring 9 that is sleeved on the connecting tube 7. The heat collecting tube dust ring 9 is made of silicone rubber and seals the gap between the connecting tube 7 and the header shell 1.

[0024] The pipes are made of metal to better neutralize the thermal expansion and contraction caused by temperature fluctuations. Quick-connectors 8, made of metal, are attached to the heat collecting tubes, which can be stainless steel bellows or copper tubes. This improves pressure-bearing capacity, facilitates assembly, and reduces the risk of collector damage. When only the connecting pipe 7 is connected to the heat collecting tube via the quick-connector 8, it can function as a circulation pipe. Alternatively, a glass tube can be placed over the heat collecting tube to form a solar water heater.

[0025] Example 2:

[0026] As attached Figure 1-3 As shown, the inner flow tube 4 is distributed along the length of the header housing 1. Both ends of the inner flow tube 4 extend to the outside of the header housing 1. The end of the inner flow tube 4 extending to the outside of the header housing 1 is provided with a metal outer thread connector 5, which is detachably mounted with a plug. The outer thread connector 5 enables the connection of multiple collectors by threading them together through straight pipes.

[0027] The outer shell end cover 2 is provided with an end cover dust ring 6 sleeved on the inner flow tube 4. The end cover dust ring 6 seals the gap between the inner flow tube 4 and the outer shell end cover 2 and is made of silicone rubber.

[0028] Example 3:

[0029] As attached Figure 1-2As shown, a partition 10 may be welded inside the inner flow tube 4. The partition 10 may be pre-installed inside the inner flow tube 4 according to the number of heat collecting tubes that need to be involved in the work when multiple heat collectors are used in combination.

[0030] The above-mentioned metal parts can preferably be stainless steel parts to enhance the ability to neutralize changes in thermal expansion and contraction.

[0031] The heat collector described in the present invention has metal pipes to improve its ability to neutralize the thermal expansion and contraction of the material caused by temperature changes. At the same time, it is connected to the heat collecting pipe with the help of a quick connector made of metal on the outside of the junction box shell, thereby improving the pressure-bearing operation capability and the convenience of assembly, and reducing the high risk of damage to the collector.
