Description

Technical Field

[0001] This utility model relates to the field of heat tracing pipe technology, and in particular to a high-efficiency heat tracing pipe. Background Technology

[0002] Heat tracing is an indirect heating method used outside or inside a pipe to prevent the fluid inside the pipe from condensing, forming condensate, or increasing in viscosity due to a drop in temperature, and to maintain a stable temperature of the fluid inside the pipe. The most common form is external heat tracing.

[0003] The existing heat tracing pipes and the pipes being traced are mostly circular, which results in the heat tracing pipes and the pipes being traced being bonded together at multiple points, resulting in a small heat transfer area. The heat transfer method mainly relies on air convection and thermal radiation, which is inefficient.

[0004] This utility model was developed to solve this problem. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a high-efficiency heat tracing pipe with simple structure and good heat tracing effect.

[0006] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a high-efficiency heat tracing pipe, including a heat tracing pipe and a heat conducting block, wherein one end of the heat conducting block is fitted with an arc-shaped surface of the pipe, the heat conducting block is provided with a placement channel that communicates with the outside, the heat tracing pipe is placed in the placement channel, the heat conducting block is provided with a sealing block at the placement channel position to seal the heat tracing pipe, and a fixing device is provided between the sealing block and the heat conducting block to prevent the sealing block from detaching.

[0007] A further improvement is that the fixing device includes symmetrically arranged fixing rods, which are mounted on the sealing block. A fixing channel is provided on the heat-conducting block, and the fixing rods pass through the fixing channel. A limiting channel is provided at the position of the fixing rods within the heat-conducting channel, and a sliding channel is provided at the position of the heat-conducting block within the limiting channel. A wedge block is slidably arranged within the sliding channel, and the limiting channel is configured to match the shape of the wedge block. A pushing element is provided within the sliding channel to push the wedge block into the limiting channel.

[0008] A further improvement is that the end of the fixing rod that contacts the wedge block has an inclined surface.

[0009] A further improvement is that the heat-conducting block extends to both sides.

[0010] A further improvement is that the surface of the heat-conducting block and the sealing block are provided with a heat-insulating layer to prevent heat loss.

[0011] A further improvement is that the pushing component is a spring, one end of which is connected to the wedge block, and the other end of which is connected to the inner wall of the sliding channel.

[0012] A further improvement is that the heat tracing pipe is a rectangular heat tracing pipe.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] It features a simple structure and excellent heat tracing effect. During use, the heat-conducting block increases the contact area with the pipe, allowing for better heat tracing. Simultaneously, the heat from the heat tracing pipe is transferred to the heat-conducting block, further enhancing heat transfer efficiency. The heat tracing pipe is sealed to the heat-conducting block by a sealing block, greatly simplifying operation and facilitating connection between the heat tracing pipe and the heat-conducting block, thus aiding installation.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figure 1-2 The present invention discloses a high-efficiency heat tracing pipe, comprising a rectangular heat tracing pipe 1, a heat-conducting block 2, and symmetrically arranged fixing rods 5. One end of the heat-conducting block 2 has an arc-shaped surface that matches and fits the pipe. The heat-conducting block 2 has a placement channel that communicates with the outside. The heat tracing pipe 1 is placed in the placement channel. The heat-conducting block 2 has a sealing block 3 at the placement channel position to seal the heat tracing pipe 1. The fixing rod 5 is placed on the sealing block 3. The heat-conducting block 2 has a fixing channel. The fixing rod 5 passes through the fixing channel. The fixing rod 5 has a limiting channel at the position of the heat-conducting channel. The heat-conducting block 2 has a sliding channel 8 at the position of the limiting channel. A wedge block 7 is slidably arranged in the sliding channel 8. The limiting channel is matched with the shape of the wedge block 7. A spring 9 is provided in the sliding channel 8 to push the wedge block 7 into the limiting channel. One end of the spring 9 is connected to the wedge block 7, and the other end of the spring 9 is connected to the inner wall of the sliding channel 8.

[0019] In operation, the heat tracing pipe 1 is placed into the placement channel, and then the sealing block 3 is placed on top. The fixing rod 5 on the sealing block 3 is inserted into the fixing channel. The wedge block 7 is pushed open, and when it reaches the bottom, the wedge block 7, pushed by the spring 9, slides into the wedge channel and engages with the fixing rod 5, thus connecting the heat tracing pipe 1 to the heat conducting block 2. Then, the arc-shaped surface of the heat conducting block 2 is attached to the external pipe. During operation, the heat tracing pipe 1 transfers heat to the heat conducting block 2, and the heat conducting block 2 then transfers heat to the pipe, thus providing heat tracing for the pipe. The heat conducting block 2 increases the contact area with the pipe, allowing for better heat tracing. At the same time, the heat from the heat tracing pipe 1 can be transferred to the heat conducting block 2, thereby increasing the heat transfer effect. The heat tracing pipe 1 is sealed to the heat conducting block 2 by the sealing block 3, which greatly facilitates the operation of the staff, makes the connection between the heat tracing pipe 1 and the heat conducting block 2 easier, and facilitates installation.

[0020] In order to push the wedge into the sliding channel 8 more smoothly, the end of the fixing rod 5 that contacts the wedge block 7 is provided with an inclined surface 6.

[0021] In order to further increase the heat conduction efficiency and improve the heat tracing effect, the heat conduction block 2 is extended to both sides.

[0022] To prevent heat loss and improve thermal conductivity, a heat insulation layer 4 is provided on the surface of the heat-conducting block 2 and the sealing block 3 to prevent heat loss. The heat insulation layer 4 can be a heat insulation cotton layer or an aerogel layer.
