Description
Technical Field
[0001] The utility model relates to the technical field of HVAC pipes, in particular to a heat preservation structure of a HVAC pipe for heating. Background Art
[0002] HVAC system refers to the general term for heating, ventilation and air conditioning systems, which includes a series of equipment, pipes and accessories to achieve indoor air comfort control. In the HVAC system, HVAC pipes are an important component used to transport heat medium, cold medium or air to achieve heat transfer and distribution.
[0003] In the HVAC system, HVAC pipes are needed to transport warm air. However, the current HVAC pipes do not have a good thermal insulation structure and cannot be insulated and protected. As a result, when the HVAC pipes are transporting warm air, the heat of the warm air is easily lost through the outer surface of the HVAC pipes, thereby affecting the heating transportation effect of the HVAC pipes. Utility Model Content
[0004] The main purpose of the utility model is to provide a heat preservation structure for a heating pipe for heating, which can effectively solve the problem that the heat of the heating pipe is easily lost during transportation.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A thermal insulation structure for a heating and ventilation pipe, comprising a No. 1 mounting shell and a No. 2 mounting shell, wherein a thermal insulation device is commonly installed at one corresponding end of the No. 1 mounting shell and the No. 2 mounting shell, a connecting device is commonly installed at the left and right ends of the No. 1 mounting shell and the No. 2 mounting shell, a No. 1 mounting frame is commonly installed at the left and right outer surfaces of the No. 1 mounting shell, and a No. 2 mounting frame is commonly installed at the left and right outer surfaces of the No. 1 mounting shell.
[0007] Preferably, the heat preservation device comprises a No. 1 aluminum foil and a No. 2 aluminum foil, and a polyurethane hard foam layer is installed at one end of each of the No. 1 aluminum foil and the No. 2 aluminum foil, and the No. 1 aluminum foil is installed on the rear inner wall of the No. 1 installation shell, and the No. 2 aluminum foil is installed on the front inner wall of the No. 2 installation shell. The polyurethane hard foam layer and the aluminum foil can be used to perform double insulation on the HVAC pipe, effectively reducing the heat loss of the HVAC pipe when delivering heating.
[0008] Preferably, the connection device includes a No. 1 connection head and a No. 2 connection head, a group of clamping columns are installed at the left end of the No. 1 connection head, a group of clamping slots are opened at the right end of the No. 2 connection head, and the No. 1 connection head and the No. 2 connection head are respectively installed at the left end and the right end of the No. 2 installation shell. The No. 1 installation shell and the No. 2 installation shell are designed in sections, that is, the No. 1 installation shell and the No. 2 installation shell can be spliced according to the length of the HVAC pipe by aligning the clamping columns on the connection device with the clamping slots, which not only improves the practicality of the device, but also when a shell somewhere is damaged, only the damaged shell needs to be replaced.
[0009] Preferably, bolt holes are provided at the upper and lower front ends of the two mounting frames No. 1 and No. 2, and four fixing bolts are installed at the front ends of the two mounting frames No. 1 and No. 2. The fixing bolts are screwed into the mounting frames No. 1 and No. 2 through the bolt holes to fix the mounting shell No. 1 and No. 2 on the HVAC pipe.
[0010] Preferably, the two mounting frames No. 1 and No. 2 are symmetrically distributed front to back.
[0011] Preferably, the clamping column and the clamping slot have the same size and corresponding positions on the left and right.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. When the HVAC pipe needs to be insulated, first install the No. 1 installation shell and the No. 2 installation shell on the outer surface of the HVAC pipe. At this time, screw the fixing bolts into the No. 1 installation frame and the No. 2 installation frame through the bolt holes, and then fix the No. 1 installation shell and the No. 2 installation shell on the HVAC pipe. In addition, the No. 1 installation shell and the No. 2 installation shell are designed in sections, that is, the No. 1 installation shell and the No. 2 installation shell can be spliced according to the length of the HVAC pipe by aligning the clamping column on the connecting device with the clamping slot. This not only improves the practicability of the device, but also when the shell somewhere is damaged, only the damaged shell needs to be replaced, and there is no need to replace the entire device.
[0014] 2. After the device is installed, the polyurethane rigid foam layer on the insulation device is a high-molecular polymer made of isocyanate and polyether as the main raw materials, mixed by special equipment under the action of various additives such as foaming agent, catalyst, flame retardant, etc., and foamed on-site by high-pressure spraying. It is a new type of synthetic material with thermal insulation and waterproof functions, so it can effectively insulate the HVAC pipes. Moreover, through the design of aluminum foil, aluminum foil is a soft metal film with the advantages of moisture-proof, airtight, light-shielding, abrasion resistance, etc., which further improves the thermal insulation effect of the polyurethane rigid foam layer.
