Description

Technical Field

[0001] This utility model relates to the field of air conditioning heat exchanger technology, specifically a finned structure for a truck air conditioning heat exchanger. Background Technology

[0002] Chinese patent document CN222048710U discloses a finned air conditioner heat exchanger assembly structure, relating to the field of heat exchanger technology. The structure includes an installation frame with an installation groove on one side. A heat exchange tube is slidably disposed within the installation groove. An installation assembly is disposed on the other side of the heat exchange tube within the installation groove. A fin assembly is clamped and fixed to the horizontal end of the heat exchange tube. An insertion hole is provided on one side of the heat exchange tube on the installation frame. A first fin assembly and a second fin assembly are clamped to both sides by a sleeve, resulting in a split structure for the fin assembly. The advantage of this structure is that, during long-term use, solid particles or dissolved substances in the fluid may adhere to the fins, forming scale and deposits. In this case, the sleeve can be removed to remove the first and second fin assemblies from the heat exchange tube, reducing the difficulty of cleaning the fins and thus improving the practicality of the device.

[0003] However, in the above-mentioned solutions and existing technologies, the finned air conditioning heat exchanger for trucks is usually fixed by tightening bolts with the help of auxiliary tools. If the bolts are not tightened during installation or the truck is bumpy while driving, the bolts may loosen, causing the air conditioning heat exchanger to become loose and risk shaking and falling, which will affect the normal use of the air conditioning heat exchanger.

[0004] Therefore, this utility model proposes a finned structure for a truck air conditioner heat exchanger to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a finned structure for a truck air conditioner heat exchanger to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A truck air conditioner heat exchanger fin structure includes:

[0007] The fixing plate is provided with two symmetrically arranged fixing plates. The fixing plates are provided with round holes for fixing and connecting multiple sets of heat exchange tubes. One end of the heat exchange tube is fixedly connected to the liquid inlet interface and the other end of the heat exchange tube is fixedly connected to the liquid outlet interface. Heat dissipation fins are fixedly provided at equal intervals on the outer wall of the heat exchange tube.

[0008] The mounting plate is fixedly mounted on the side wall of the fixing plate. The mounting plate has mounting holes for mounting bolts to fix the fixing plate. The mounting plate is provided with limit components and auxiliary components.

[0009] Preferably, the T-shaped groove in the limiting component is formed on the side wall of the fixed plate, and two L-shaped baffles are symmetrically arranged. The L-shaped baffles are engaged with the mounting bolts, and T-shaped blocks are fixedly arranged on the side wall of the L-shaped baffles. The T-shaped blocks are movably engaged in the T-shaped groove.

[0010] Preferably, a slider is fixedly provided on the inner side wall of the L-shaped baffle, a slide groove is opened on the side wall of the mounting plate, the slider is movably engaged in the slide groove, and the locking block is fixedly provided on the side wall of the L-shaped baffle.

[0011] Preferably, the card block has a card slot on its side wall, and the two ends of the card plate are engaged in the card slot.

[0012] Preferably, the protrusion in the auxiliary component is fixedly mounted on the side wall of the mounting plate, and a plug rod is movably sleeved on the protrusion. A pull ring is fixedly mounted at the end of the plug rod, and a limiting block is fixedly sleeved on the plug rod.

[0013] Preferably, the insert rod is sleeved with a spring, and the two ends of the spring are respectively engaged with the limiting block and the protrusion. The insertion hole is opened on the side wall of the card plate, and the insert rod is inserted into the insertion hole. The first magnetic block is symmetrically fixedly embedded on the two side walls of the insert rod, and the second magnetic block is fixedly embedded on the side wall of the L-shaped baffle. The first magnetic block and the second magnetic block attract each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] After tightening the mounting bolts to pass through the mounting holes and complete the installation of the fixing plate, move the slider along the slide groove to the end, causing the L-shaped baffle to move so that its inner wall engages with the end cap of the mounting bolt. After the two ends of the baffle are engaged in the slot, the spring returns and pushes the insert rod to engage with the insertion hole to fix the position of the baffle, thereby fixing the position of the L-shaped baffle and limiting the mounting bolt. The operation is simple and effectively avoids loosening of the mounting bolts, further ensuring the installation stability of the truck finned air conditioning heat exchanger and ensuring the normal use of the air conditioning heat exchanger.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figures 1-7 The present invention provides the following two preferred embodiments:

[0026] Example 1: A finned structure for a truck air conditioner heat exchanger, comprising: a fixing plate 1, two of which are symmetrically arranged; the fixing plate 1 has round holes for fixedly connecting multiple sets of heat exchange tubes 2; one end of the heat exchange tube 2 is fixedly connected to a liquid inlet 3, and the other end is fixedly connected to a liquid outlet 4; heat dissipation fins 5 are fixedly arranged at equal intervals on the outer wall of the heat exchange tube 2; and a mounting plate 6, which is fixedly mounted on the side wall of the fixing plate 1; the mounting plate 6 has mounting holes 7 for mounting bolts 8 for fixing the fixing plate 1; and the mounting plate 6 is provided with limit components and auxiliary components. The T-shaped groove 9 in the limiting assembly is formed on the side wall of the fixed plate 1. Two L-shaped baffles 10 are symmetrically arranged. The L-shaped baffles 10 are engaged with the mounting bolts 8. A T-shaped block 11 is fixedly set on the side wall of the L-shaped baffle 10 and is movably engaged in the T-shaped groove 9. A slider 12 is fixedly set on the inner side wall of the L-shaped baffle 10. A sliding groove 13 is formed on the side wall of the mounting plate 6 and the slider 12 is movably engaged in the sliding groove 13. A locking block 14 is fixedly set on the side wall of the L-shaped baffle 10. A locking groove 15 is formed on the side wall of the locking block 14 and the two ends of the locking plate 16 are engaged in the locking groove 15.

[0027] In use, tighten the mounting bolt 8 to pass through the mounting hole 7 to complete the installation of the fixing plate 1, thus initially completing the installation of the truck finned air conditioning heat exchanger. Move the slider 12 along the slide groove 13 to the end, so that the L-shaped baffle 10 moves and its inner wall engages with the end cap of the mounting bolt 8. The T-shaped block 11 moves in the T-groove 9 to ensure the stability of the L-shaped baffle 10. Then, the two ends of the clamping plate 16 are clamped and fixed in the clamping groove 15 to fix the position of the L-shaped baffle 10, thereby limiting the mounting bolt 8. The operation is simple and effectively avoids the loosening of the mounting bolt 8, further ensuring the installation stability of the truck finned air conditioning heat exchanger and ensuring the normal use of the air conditioning heat exchanger.

[0028] Example 2: Based on Example 1, the protrusion 17 in the auxiliary component is fixedly installed on the side wall of the mounting plate 6. A plug rod 18 is movably sleeved on the protrusion 17. A pull ring is fixedly installed at the end of the plug rod 18. A limiting block 19 is fixedly sleeved on the plug rod 18. A spring 20 is sleeved on the plug rod 18. The two ends of the spring 20 are respectively engaged with the limiting block 19 and the protrusion 17. An insertion hole 21 is opened on the side wall of the clamping plate 16. The plug rod 18 is inserted into the insertion hole 21. The first magnetic block 22 is symmetrically fixedly embedded on the two side walls of the plug rod 18. The second magnetic block 23 is fixedly embedded on the side wall of the L-shaped baffle 10. The first magnetic block 22 and the second magnetic block 23 attract each other.

[0029] During use, when installing the clamping plate 16, pull the pull ring at the end of the insert rod 18 to move it, causing the limiting block 19 to compress the spring 20. After the two ends of the clamping plate 16 are engaged in the slot 15, release the pull ring. The spring 20 will then return to its original position and push the insert rod 18 into the insertion hole 21 to fix the position of the clamping plate 16, thereby fixing the position of the L-shaped baffle 10 and ensuring the limiting effect on the mounting bolt 8. When installing or removing the mounting bolt 8, move the L-shaped baffle 10 so that the second magnetic block 23 on its side wall attracts the first magnetic block 22 on the side wall of the insert rod 18, preventing the L-shaped baffle 10 from moving arbitrarily and affecting the installation or removal of the mounting bolt 8.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
