Description

Technical Field

[0001] The utility model relates to a novel antifreeze core installation component, belonging to the technical field of solar energy thermal utilization. Background Art

[0002] The antifreeze core in a solar collector refers to a device used to prevent the solar collector from freezing in cold climates. It usually consists of a pipe system filled with an antifreeze liquid (such as ethylene glycol water solution) and is installed inside or around the collector plate of the collector. In cold climates, water may freeze inside the collector, causing damage or even destruction of the collector. The antifreeze liquid in the antifreeze core has antifreeze properties, which can effectively prevent the collector from freezing and ensure the normal operation of the collector.

[0003] When disassembling the antifreeze core pipe in the traditional way, the pipes need to be disassembled one by one. The removal and installation of the antifreeze core may require professional techniques and tools. The operation may be complicated, and there is a risk of damage to the collector or injury due to improper operation. At the same time, when the ambient temperature drops below zero, the water in the copper flow channel stops flowing and begins to become a mixture of ice, water, and air. Pressure will be generated in the closed pipe, and this pressure will squeeze around. Since the copper pipe is made of metal, it can withstand pressure below 2.0MPA. At this time, the pressure will be guided by the inner wall of the pipe to squeeze towards the antifreeze core. Since the traditional antifreeze core is a closed structure, the metal flow channel is prone to fatigue cracking due to excessive expansion times or excessive internal pressure.

[0004] Therefore, it is necessary to design a new antifreeze core installation assembly to facilitate replacement and ensure the safety of the metal runner. Utility Model Content

[0005] In view of the problems existing in the above-mentioned prior art, the utility model provides a novel antifreeze core installation component to solve the above-mentioned technical problems.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new antifreeze core installation assembly, comprising an upper metal runner, a lower metal runner and a reducing three-way connector located between the upper metal runner and the lower metal runner; one end of the upper metal runner extends into the interior of the heat collecting manifold, and the other end is connected to one of the connection ports 1 of the reducing three-way connector; one end of the lower metal runner extends into the interior of the heat collecting plate, and the other end is connected to one of the connection ports 2 of the reducing three-way connector; an antifreeze core is arranged at the internal channel of the lower metal runner and the reducing three-way connector; the antifreeze core is composed of a hose with one end closed and the other end open, the closed end of which is arranged at the bottom of the lower metal runner, and the open end is located at the three connection ports obliquely arranged of the reducing three-way connector; an antifreeze core replacement port is arranged in the open end tube of the antifreeze core; the antifreeze core replacement port is arranged in an open structure at one end of the antifreeze core, and the other protruding end is a closed port; a vent is arranged on the side of the closed port to communicate with the outside atmosphere.

[0007] Furthermore, the reducing three-way connector and the antifreeze core are both made of silicone soft material.

[0008] Furthermore, the upper metal runner extends into one of the connection ports of the reducer tee connector, and the two are fixed by a locking buckle.

[0009] Furthermore, the lower metal runner extends into one of the second connection ports of the reducer tee connector, and the two are fixed by a locking buckle.

[0010] Furthermore, the open end of the antifreeze core is fixed and locked to the obliquely arranged connection port 3 of the reducing tee connector by a locking buckle.

[0011] Furthermore, the antifreeze core tube is provided with cross reinforcement ribs, which adopt a fiber-reinforced structure and can be arranged along the length direction of the hose and cross-arranged inside the hose to form a cross-shaped reinforcement structure.

[0012] The beneficial effects of the utility model are as follows: the silicone antifreeze core of this structure is opened at one end to communicate with the atmosphere, which can be more freely retracted and released, avoiding fatigue cracking of the metal flow channel due to excessive expansion times or excessive internal pressure. The antifreeze core is designed to be able to be pulled out or inserted from the three-way opening for easy replacement, avoiding the problem that the entire module cannot be used for antifreeze due to aging of the antifreeze core and being unable to be replaced. The antifreeze core is designed with a cross reinforcement rib structure inside, which improves the support force of the hollow part of the silicone antifreeze core, thereby allowing the antifreeze core to maintain sufficient compression space before freezing.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0018] like Figure 1 , Figure 2 As shown, a new type of antifreeze core installation assembly comprises an upper metal runner 1, a lower metal runner 2 and a reducer tee connector 3 located between the upper metal runner 1 and the lower metal runner 2; one end of the upper metal runner 1 extends into the interior of the heat collecting manifold, and the other end is connected to one of the connection ports 1 31 of the reducer tee connector 3; one end of the lower metal runner 2 extends into the interior of the heat collecting plate, and the other end is connected to one of the connection ports 2 32 of the reducer tee connector 3; the lower metal runner 2 is connected to the reducer An antifreeze core 4 is arranged at the internal channel of the three-way connector 3; the antifreeze core 4 is composed of a hose with one end closed and the other end open, the closed end of which is arranged at the bottom of the lower metal runner 2, and the open end is located at the connecting port 33 arranged obliquely on the reducing three-way connector 3; an antifreeze core replacement port 6 is arranged in the open end tube of the antifreeze core 4; the antifreeze core replacement port 6 extends into the antifreeze core 4 at one end with an open structure, and the other protruding end is a closed port; a vent 61 is arranged on the side of the closed port to communicate with the outside atmosphere.

[0019] In this embodiment, preferably, the reducing three-way connector 3 and the antifreeze core 4 are both made of silicone soft material.

[0020] In the preferred embodiment, the upper metal runner 1 extends into one of the connection ports 31 of the reducing tee connector 3 , and the two are fixed by a locking buckle 5 .

[0021] In this embodiment, the lower metal runner 2 extends into one of the second connection ports 32 of the reducing tee connector 3 , and the two are fixed by a locking buckle 5 .

[0022] Preferably, in this embodiment, the open end of the antifreeze core 4 is fixed and locked to the obliquely arranged connection port 3 33 of the reducing tee connector 3 by a locking buckle 5 .

[0023] Preferably, in this embodiment, a cross reinforcement rib is provided inside the antifreeze core 4 tube. The cross reinforcement rib adopts a fiber reinforced structure and can be arranged along the length direction of the hose and cross-arranged inside the hose to form a cross-shaped reinforcement structure.

[0024] Working principle: When the ambient temperature drops below zero, the water in the copper flow channel stops flowing and begins to become a mixture of ice, water, and air. The volume of the mixture is about 11% larger than the volume of water, which will cause the space in the pipe to expand to a certain extent. At this time, pressure will be generated in the closed pipe, and this pressure will squeeze around. Since the copper pipe is made of metal, it can withstand pressure below 2.0MPA. At this time, the pressure will be guided by the inner wall of the pipe to squeeze toward the antifreeze core. The antifreeze core will shrink and squeeze the internal air into the external atmosphere after being under pressure. The designed emptying force and shrinkage can just absorb the expanded part of this mixture, thereby ensuring that the metal flow channel will not be damaged by the expansion force. When the ambient temperature exceeds zero degrees, the ice melts as the temperature rises, the volume slowly shrinks, the pressure in the pipe disappears, the antifreeze core slowly automatically restores its original shape due to the tension of the structure, the water begins to flow, and the water in the flow channel resumes normal flow.

[0025] The silicone antifreeze core of the utility model has one end opening to communicate with the atmosphere, which can be more freely retracted and released, avoiding fatigue cracking due to excessive expansion times or excessive internal pressure. The antifreeze core is designed to be able to be pulled out or inserted through the three-way opening for easy replacement, avoiding the problem that the entire module cannot be used for antifreeze due to the antifreeze core aging and being unable to be replaced over time. The antifreeze core is designed with a cross reinforcement rib structure inside, which improves the support force of the hollow part of the silicone antifreeze core and ensures that the antifreeze core maintains sufficient compression space before freezing.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
