Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, and particularly relates to a heat exchange device for an air source heat pump. Background Art

[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source (air) to a high-level heat source. It is a form of heat pump. As the name implies, a heat pump can convert low-level thermal energy that cannot be directly utilized (such as heat contained in air, soil, and water) into high-level thermal energy that can be utilized, just like a pump.

[0003] Currently, for the heat exchange device of an air source heat pump, a heat pipe base tube is connected to a tube shell, and evenly distributed annular fins are arranged on the outer wall of the heat pipe base tube. After long-term use, sundries are likely to accumulate in the gaps between the annular fins, affecting the heat exchange effect of the fins. When cleaning the annular fins, it is necessary to insert a cleaning rod into the gaps at different positions of the fins one by one for cleaning, which is cumbersome and inconvenient.

[0026] In the following description, many specific details are set forth to fully understand the present utility model.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0029] The present utility model provides a heat exchange device for an air source heat pump. When scaling occurs in the gaps of the spiral fins, a cleaning rod can be inserted into the gaps of the spiral fins, and by rotating the heat pipe base tube, the spiral grooves can be cleaned in a thread feeding manner, without the need to clean each gap individually, which is convenient and labor-saving. Please refer to Figures 1 - 5 , including: a shell 100 and a heat exchange pipe fitting 200.

[0030] The shell 100 includes a tube body 110 and a groove 120, and a groove 120 is opened at the top of the tube body 110;

[0031] Among them, the groove 120 is an annular groove for installing the heat exchange pipe fitting 200.

[0032] The heat exchange pipe fitting 200 is arranged inside the groove 120. The heat exchange pipe fitting 200 includes a heat pipe base tube 210, spiral fins 220 and a mounting block 230. The spiral fins 220 are arranged outside the heat pipe base tube 210, and a mounting block 230 that fits with the groove 120 is arranged on the heat pipe base tube 210;

[0033] Among them, the heat pipe base tube 210 is connected to the groove 120 of the shell 100 through the mounting block 230. As Figure 3 shown, the spiral fins 220 are spiral, and there are spiral gaps, that is, spiral grooves, between the fins.

[0034] Since the direct insertion connection between the mounting block 230 and the groove 120 of the shell 100 has poor stability, a limiting block 130 is arranged inside the groove 120. A sliding groove 140 is opened inside the limiting block 130. A limiting groove 150 communicated with the sliding groove 140 is arranged on the outer side of the tube body 110. An anti-rotation groove 240 corresponding to the limiting block 130 is arranged on the outer side wall of the mounting block 230. An inclined surface pressing groove 250 is arranged at the inner top end of the anti-rotation groove 240. A fastening member 300 is arranged inside the sliding groove 140, and an adjusting member 400 is arranged at the top end of the tube body 110;

[0035] Among them, after the mounting block 230 is inserted into the groove 120, the limiting block 130 is engaged with the anti-rotation groove 240 to achieve anti-rotation limiting. The sliding groove 140 and the limiting groove 150 form a T-shaped groove that is wider inside and narrower outside. The fastening member 300 can slide in the T-shaped groove. By moving the adjusting member 400 upward, the fastening member 300 is squeezed, so that the fastening member 300 moves towards the inclined surface pressing groove 250, and the fastening member 300 is held on the inclined surface pressing groove 250 to prevent the structure from loosening.

[0036] Specifically, the fastener 300 includes a T-shaped slider 310 and a pressing inclined surface 320. One end of the T-shaped slider 310 is connected to the sliding groove 140, and the other end of the T-shaped slider 310 is connected to the limiting groove 150. Pressing inclined surfaces 320 are provided at the bottoms of both ends of the T-shaped slider 310;

[0037] The T-shaped slider 310 is slidably connected to the T-shaped groove. When the adjusting member 400 moves upward, it presses the pressing inclined surface 320 at the outer end of the T-shaped slider 310, causing the T-shaped slider 310 to move inward toward the inside of the groove 120. Finally, the pressing inclined surface 320 on the inner side of the T-shaped slider 310 presses on the inclined surface pressing groove 250 to limit and fix the mounting block 230.

[0038] Specifically, the adjusting member 400 includes an end cap 410 and a pressing inclined surface 420. The end cap 410 is screwed to the top end of the pipe body 110, and a pressing inclined surface 420 corresponding to the pressing inclined surface 320 is provided on the top of the end cap 410;

[0039] Among them, the inside of the end cap 410 has internal threads, and the outer wall of the top end of the pipe body 110 is provided with external threads. As Figure 2 and Figure 5 shown, rotate the end cap 410 to make the end cap 410 move under the action of the thread feed. The end cap 410 moves upward, so that the pressing inclined surface 420 contacts the pressing inclined surface 320 on the outer side of the T-shaped slider 310. Under the pressing action of the inclined surface, the pressing inclined surface 320 on the inner side of the T-shaped slider 310 is made to press on the inclined surface pressing groove 250.

[0040] To ensure the pressing effect, when the end cap 410 moves upward to the top flush with the top end of the pipe body 110, the left end of the T-shaped slider 310 contacts the inclined surface pressing groove 250 through the pressing inclined surface 320.

[0041] Since the heat exchange pipe fitting 200 needs to be taken and placed, when the T-shaped slider 310 is pulled out to the outermost end, the T-shaped slider 310 is immersed in the sliding groove 140, and the inner side of the T-shaped slider 310 is vertically offset from the mounting block 230 to prevent the T-shaped slider 310 from blocking the mounting block 230 when taking and placing the heat exchange pipe fitting 200.

[0042] During specific use, the mounting block 230 of the heat exchange pipe fitting 200 is inserted into the groove 120. During the insertion process, the limiting block 130 is engaged with the anti-rotation groove 240 to achieve anti-rotation limiting. Then rotate the end cap 410. The end cap 410 moves upward under the action of the thread feed, so that the pressing inclined surface 420 contacts the pressing inclined surface 320 on the outer side of the T-shaped slider 310. Under the pressing action of the inclined surface, the T-shaped slider 310 is caused to move inward toward the inside of the groove 120. Finally, the pressing inclined surface 320 on the inner side of the T-shaped slider 310 presses on the inclined surface pressing groove 250 to limit and fix the mounting block 230, eliminating the need to repeatedly turn the bolts for connection and fixing, making the installation and disassembly convenient and fast;

[0043] There is a spiral gap, i.e., a spiral groove, between the fins of the spiral fin 220. During scaling, the external cleaning rod is inserted into one end of the spiral groove of the spiral fin 220, and the heat pipe base tube 210 is rotated so that the cleaning rod moves along the spiral groove. The cleaning process is simple and convenient, and there is no need to insert and extract the cleaning rod back and forth.

[0044] Although the present utility model has been described with reference to the embodiments above, various improvements can be made to it and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the present utility model can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
