In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary details.
[0033] Please refer to Figure 1 The present application provides a heat exchange pipe, which comprises a pipe body 10, a spoiler 20, a locking piece 40 and an elastic scale piece 30. The spoiler 20 has opposite positioning ends 21 and pipe penetrating ends 22. The pipe penetrating ends 22 penetrate into the inside of the pipe body 10 from one end of the pipe body 10 and extend out from the other end. The positioning ends 21 and the pipe penetrating ends 22 are both located outside the pipe body 10, and the positioning ends 21 are provided with abutting parts 50 for abutting with the end face of one end of the pipe body 10. The locking piece 40 is used for locking the pipe penetrating ends 22 extending out of the pipe body 10, so that the spoiler 20 penetrates through the pipe body 10 in a straight line direction. The elastic scale piece 30 is arranged in the pipe body 10 and around the spoiler 20. The two ends of the elastic scale piece 30 are connected with the two ends of the spoiler 20 penetrating into the inside of the pipe body 10, respectively, and the elastic scale piece 30 is in contact with the inner wall of the pipe body 10. When the fluid in the pipe body 10 hits the elastic scale piece 30, the elastic scale piece deforms to scrape off the dirt on the inner wall of the pipe body 10.
[0034] Exemplarily, the penetrating end 22 of the spoiler 20 is penetrated into the pipe body 10 from one end of the pipe body 10 and extends out from the other end, and the penetrating end 22 is locked by the locking member 40, and the abutting portion 50 provided on the positioning end 21 abuts against the end face of the pipe body 10, so that the spoiler 20 penetrates through the pipe body 10 in a straight line direction; if the spoiler 20 needs to be replaced or cleaned, the locking member 40 is only needed to be disengaged from the locking of the penetrating end 22, and then the positioning end 21 is held and pulled outward, so that the spoiler 20 is quickly pulled out of the pipe body 10, which is simple in structure and convenient to disassemble and assemble. It should be noted that the spoiler 20 provided in the pipe body 10 can change the flow path of the fluid, promote the transition from laminar flow to turbulent flow, and further make the fluid mix more fully in the turbulent state, reduce the thickness of the thermal boundary layer, and also induce the fluid to generate rotation or periodic disturbance, form secondary flow and vortex, and further enhance heat transfer. In addition, the increased turbulent effect of the spoiler 20 can reduce the deposition of particles or impurities on the inner wall of the pipe body 10, delay the formation of dirt, and further prolong the cleaning period.
[0035] In order to further reduce the problem of wall deposition and fouling of the inner wall of the pipe body 10, the elastic scraping member 30 is provided around the spoiler 20, so that the fluid entering the pipe body 10 is converted from laminar flow to turbulent flow state under the action of the spoiler 20, the elastic scraping member 30 is impacted in various random directions by the fluid in the turbulent state, and the elastic scraping member 30 is forced to stretch and contract vibration, so that the elastic scraping member 30 can be scraped on the inner wall of the pipe body 10, thereby removing the dirt on the inner wall of the pipe body 10 and preventing the accumulation of dirt to cause pipe blockage, thereby ensuring that the heat transfer of the inner wall of the tank is not affected by fouling.
[0036] That is, the heat exchange pipe of the present embodiment is provided with the elastic scraping member 30 around the part of the spoiler 20 penetrating into the pipe body 10, and the fluid is converted from laminar flow to turbulent flow state under the action of the spoiler 20, so as to impact the elastic scraping member 30 in various random directions, and the elastic scraping member 30 is forced to stretch and contract vibration, thereby achieving the scraping of the inner wall of the pipe body 10 to remove the dirt on the inner wall, effectively solving the problems of wall deposition, fouling and blockage caused by dirt accumulation of the fluid medium in the pipe body 10. Meanwhile, the penetrating end 22 penetrating out of the pipe body 10 is locked by the locking member 40, and the abutting portion 50 on the positioning end 21 abuts against the end face of the pipe body 10, so that the spoiler 20 is detachably provided in the pipe body 10, thereby facilitating subsequent maintenance, maintenance and cleaning.
[0037] Exemplarily, the shape of the spoiler 20 can be set correspondingly according to the characteristics of the fluid, for example, for high viscosity and low flow rate fluid, the shape of the spoiler 20 can be spiral; for low viscosity and high flow rate fluid, the shape of the spoiler 20 can be corrugated; for clean fluid, the shape of the spoiler 20 can be concave hole. That is, the shape of the spoiler 20 is any one of spiral, corrugated and concave hole.
[0038] Referring to Figure 1 and Figure 2 In an embodiment, the elastic scraping member 30 includes at least one spring 31, the spring 31 is arranged around the part of the spoiler 20 extending into the pipe body 10 along the length direction of the pipe body 10, and the outer peripheral surface of the spring 31 is in contact with the inner wall of the pipe body 10. That is, the fluid is converted into a turbulent state under the action of the spoiler 20 and hits the spring 31 in all directions, so that the spring 31 is forced to stretch and contract vibration, and since the outer peripheral surface of the spring 31 is in contact with the inner wall of the pipe body 10, the spring 31 can scrape the inner wall of the pipe body 10, thereby removing the dirt on the inner wall.
[0039] Here, it should be noted that the above-mentioned term "at least one" means one or more, which can be set correspondingly according to the characteristics of the fluid. If the elastic scraping member 30 includes one spring 31 according to the characteristics of the fluid, the part of the spoiler 20 extending into the pipe body 10 can be provided with a hanging hole 20a at both ends, and the two ends of the spring 31 are connected in the two hanging holes 20a respectively, so as to realize the detachable connection of the spring 31 on the spoiler 20, which is convenient for subsequent maintenance, maintenance or cleaning. If the elastic scraping member 30 includes multiple springs 31 according to the characteristics of the fluid, multiple hanging holes 20a can be provided on the part of the spoiler 20 extending into the pipe body 10 along the length direction of the pipe body 10, and the two ends of a single spring 31 are connected in the adjacent two hanging holes 20a respectively, so as to realize the detachable connection of the multiple springs 31 on the spoiler 20 in turn, which is convenient for subsequent maintenance, maintenance or cleaning.
[0040] Referring to Figure 3 Further, when the part of the spoiler 20 extending into the pipe body 10 is provided with multiple hanging holes 20a, the middle part of the spoiler 20 is outwardly protruded to form a protruding part 23, and the protruding part 23 is located outside the hanging hole 20a, which is used to abut the adjacent two springs 31. In this way, it can be ensured that each section of the spring 31 can automatically stretch and contract in the pipe body 10, thereby playing a role of scraping the inner wall of the pipe body 10.
[0041] Exemplarily, the cross section of the spring 31 can be set to a corresponding shape according to the specific needs of the physical and chemical characteristics of the fluid medium in the pipe body 10. Among them, the cross section of the spring 31 is one of circular, square, triangular, oval and sheet.
[0042] In one embodiment, the pipe penetrating end 22 is provided with a locking hole 22a, and the locking member 40 is inserted into the locking hole 22a to lock the spoiler 20.
[0043] In one embodiment, the abutting portion 50 is provided with two, which are respectively arranged on the upper surface and the lower surface of the positioning end 21. In this way, the two abutting portions 50 abut against the end surface of the pipe body 10, and cooperate with the locking member 40 to lock the pipe penetrating end 22, so as to fix the spoiler 20 in the pipe body 10 in a straight line direction.
[0044] In one embodiment, the width L2 of the pipe penetrating end 22 and the width L1 of the positioning end 21 are both less than the pipe diameter of the pipe body 10. In this way, it is ensured that the spoiler 20 can normally pass through the pipe body 10, and the spoiler 20 cannot be fixed in the pipe body 10 due to the width being greater than the pipe diameter of the pipe body 10.
[0045] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application should belong to the scope of the claims of the present application.
