Description

Technical Field

[0001] The present application relates to the technical field of HVAC pipes, and specifically discloses an outdoor energy-saving and antifreeze HVAC pipe. Background Art

[0002] HVAC pipes are a key component of HVAC projects, used to deliver heating. During HVAC installation, some pipes are often installed outdoors due to factors such as the geographical conditions and spatial layout of the installation. During winter, when heating demand is high, these pipes are susceptible to freezing, resulting in heat loss and reduced heat delivery efficiency, leading to a shortage of heating. Therefore, HVAC pipes require antifreeze insulation.

[0003] Existing antifreeze and insulation measures include using electric heating to insulate HVAC pipes, but this method consumes a lot of energy and is therefore rarely used in daily HVAC pipe antifreeze applications. Another approach is to add insulation sleeves to the exterior of HVAC pipes to prevent freezing. However, existing insulation sleeves are difficult to install on HVAC pipes and are also difficult to maintain and replace after aging and damage. In light of this, the inventors have developed an outdoor energy-saving and antifreeze HVAC pipe to address these issues. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the traditional thermal insulation sleeve of the HVAC pipe is inconvenient to install on the HVAC pipe and it is inconvenient to maintain and replace the thermal insulation sleeve after it is damaged due to aging.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides an outdoor energy-saving and anti-freeze heating ventilation pipe, including a pipe body for conveying warm air and an insulation part that can be detachably mounted on the outside of the pipe body, the inner wall of the pipe body is provided with a heat-insulating layer, the outside of the pipe body is provided with a first insulation layer, the surface of the first insulation layer is provided with a waterproof layer, the insulation part includes a first protective shell and a second protective shell that are hinged to each other on one side and used to accommodate and wrap the side of the pipe body, sealing rings symmetrically embedded in the inner walls of both ends of the first protective shell and the second protective shell, and a second insulation layer respectively provided on the inner sides of the first protective shell and the second protective shell, the first protective shell and the second protective shell are both semicircular tube structures, a locking part is provided between the free side of the first protective shell and the free side of the second protective shell, and the two ends of the first protective shell and the second protective shell are also symmetrically provided with clips located at the end away from the sealing ring.

[0006] The principles and effects of this basic solution are:

[0007] 1. Compared with the existing technology, the utility model transports warm air by setting a pipe body and setting a heat insulation layer on the inner wall of the pipe body, which can not only insulate the warm air transported inside the pipe body, but also reduce the loss of warm air during transportation and improve the efficiency of warm air transportation. The warm air transported in the pipe body is insulated by heat insulation materials. Compared with the existing electric heating, heat preservation and antifreeze method, not only is the structure simpler, but the overall heat preservation and antifreeze measures are more energy-saving and power-saving.

[0008] 2. Compared with the prior art, the present invention facilitates wrapping and protecting the pipe body by providing a hinge and a locking piece for the first protective shell and the second protective shell, and facilitates sealing the side of the area surrounded by the first protective shell and the second protective shell by providing a clamping piece and a sealing ring, thereby avoiding direct contact and heat exchange between the low temperature and the pipe body. By providing a waterproof layer, the pipe body is facilitated to be installed and used outdoors, solving the problem that the traditional insulation cover of the HVAC pipe is inconvenient to install on the HVAC pipe and is inconvenient to maintain and replace the insulation cover after aging and damage.

[0009] Furthermore, the locking member includes a first connecting block provided on the free side of the first protective shell, a second connecting block provided on the free side of the second protective shell, and a plurality of locking bolts threadably connected between the first and second connecting blocks. The threaded connection between the first and second connecting blocks and the locking bolts achieves a locked connection between the free sides of the first and second protective shells, thereby facilitating comprehensive wrapping and protection of the outer side of the tube body. The structure is simple and easy to assemble and disassemble.

[0010] Furthermore, the clamping member includes clamping grooves symmetrically provided at both ends of the free side of the first protective shell, and clamping blocks symmetrically provided at both ends of the free side of the second protective shell and removably engaged with the clamping grooves. The clamping of the clamping blocks with the clamping grooves facilitates the installation and fixation of the ends of the first and second protective shells, thereby achieving a better thermal insulation effect around the tube body.

[0011] Furthermore, the sealing rings are elastomeric structures, each consisting of a semi-ring embedded within the first and second protective shells, with the inner diameter of the sealing rings being smaller than the outer diameter of the tube. By providing the sealing rings with adjustable elasticity and having an inner diameter smaller than the outer diameter of the tube, the first and second protective shells can seal the ends of the tube via the sealing rings, not only waterproofing the tube but also insulating the tube, preventing heat from being lost through heat exchange with the outside world through the side ends of the tube.

[0012] Furthermore, the surfaces of the first protective shell and the second protective shell are both provided with a fireproof layer, which facilitates fire protection of the pipe body. BRIEF DESCRIPTION OF THE DRAWINGS

The first protective shell 5 and the second protective shell 6 are also symmetrically provided with clips at both ends located at the end away from the sealing ring 7.

[0019] Among them, such as Figure 1 As shown, the locking member includes a first connecting block 9 provided on the free side of the first protective shell 5, a second connecting block 10 provided on the free side of the second protective shell 6, and two locking bolts 11 threadably connected between the first connecting block 9 and the second connecting block 10.

[0023] During the specific implementation of the present invention, the two ends of the pipe body 1 are sealed and connected to the HVAC pipe of the indoor part respectively, and then the first protective shell 5 and the second protective shell 6 are opened first, and the first protective shell 5 is installed on the bottom side of the pipe body 1, and the first protective shell 5 completely wraps the bottom side of the pipe body 1, and the sealing rings 7 at the left and right ends of the first protective shell 5 are also squeezed between the first protective shell 5 and the pipe body 1.
