The utility model discloses a heat exchanger 100 can improve heat exchanger 100's heat exchange efficiency, prolongs heat exchanger 100's defrosting cycle.
Referring to fig. 1 to 3, in a first embodiment of a heat exchanger 100 of the present invention, the heat exchanger 100 includes a plurality of fins 120 and a heat exchange tube 110 passing through the plurality of fins 120, a width of the fins 120 is L0, and the heat exchange tube 100 includes a first heat exchanger and a second heat exchangerThe heat exchange pipe 110 has a pipe diameter D,
wherein D is equal to [4mm, 10mm ]]，3.2≤k≤6。
Specifically, a plurality of the fins 120 are sequentially arranged at intervals, and the heat exchange tube 110 is wound on the fins 120 through the plurality of the fins 120. The fin 120 may have any one or more of flat fins, louvers, bridges and corrugated fins. When the fins 120 are irregular-sheet type, the width of the fin 120 should be the width of the projection surface of the fin 120 to another adjacent fin 120.
For the conventional heat exchanger 100, when the pipe diameter of the heat exchange pipe 110 is 4 mm-10 mm, the k value is only 2.8-3.0, the width of the fins 120 is insufficient, and the heat exchange efficiency is low. To the utility model discloses a heat exchanger 100, when the pipe diameter of heat exchange tube 110 was 4mm ~ 10mm, after the pipe diameter of selected heat exchange tube 110 (for example, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm etc.), the foundation
That is, since k is 3.2 ≦ k ≦ 6, the width of the fin 120 is 12.8 to 60mm, for example, 15mm, 20mm, 30mm, 40mm, 50mm, and the like.
In order to verify the influence of the k value on the heat exchanger 100, the heat exchanger 100 with different k values is tested under the same working condition, and the test data is as follows:
table 1. when the heat exchange tube pipe diameter was 4mm, the heat exchanger test data table:
table 2. when the heat exchange tube pipe diameter was 6mm, the heat exchanger test data table:
table 3. when the heat exchange tube pipe diameter was 8mm, the heat exchanger test data table:
table 4. when the heat exchange tube diameter was 10mm, the heat exchanger test data table:
from the data recorded in tables 1 to 4 above, at D ∈ [4mm, 10mm ], the following can be analyzed:
(1) when the k value is less than 3.2, the heating capacity of the heat exchanger 100 is 3255 w-3573 w, and the heating capacity is less than 3600 w; the defrosting period is 41.2 min-58.5 min, and is less than 1 h.
(2) When the k value is 3.2-6.0, the heating capacity of the heat exchanger 100 is gradually enhanced to be 3634 w-4048 w, the heating capacity exceeds 3600w, and the heating capacity is enhanced by 11.1% -13.4% relative to the heat exchanger 100 with the k value of 2.8-3.0. In addition, the defrosting period is 64.6-89 min, the defrosting period exceeds 1h, and the defrosting period is prolonged by 47-57% relative to a heat exchanger 100 with a k value of 2.8-3.0.
(3) When the k value is more than 6.0, the heating capacity of the heat exchanger 100 is gradually reduced to 3425 w-3592 w, and the heating capacity is lower than 3600 w; the defrosting period is 41.5 min-56.4 min, and is less than 1 h.
It can be seen that the larger the k value of the heat exchanger 100 is, the better the k value of the heat exchanger 100 is, and the k value of the heat exchanger 100 should be kept within a certain range so as to ensure that the fin 120 has a sufficient width while the structure of the heat exchanger 100 is compact. Here, when the tube diameter of the heat exchange tube 110 is 4mm to 10mm, the k value of the heat exchanger 100 is preferably 3.2 to 6.0, for example, 3.5, 4.0, 4.5, 5.0, 5.5, and the like.
The utility model discloses a heat exchanger 100, when the pipe diameter of heat exchange tube 110 is at 4mm ~ 10mm, through injecing
And k is not less than 3.2 and not more than 6, so that the heat exchanger 100 is ensured to have enough fin width while the pipe diameter of the heat exchange pipe 110 is reduced, the fin 120 can improve the heat exchange efficiency reduction and slow down the frosting speed, the defrosting period is further prolonged, the frost-containing water is favorably discharged, the thermal comfort is improved, and the small-pipe-diameter heat exchanger 100 can be applied to the heat exchanger 100 of the air conditioner outdoor unit. Of course, the heat exchanger 100 can also be applied to an indoor unit of an air conditioner, and the application range is wide.
In addition, when the pipe diameter of the heat exchange pipe 110 is 4 mm-10 mm, k is more than or equal to 3.2 and less than or equal to 6, the frost containing volume of the heat exchanger 100 can reach more than 85 percent of the frost containing volume of a conventional heat exchanger (about 7mm of the heat exchange pipe and about 22mm of the fin width), so that the fin width can be reduced as far as possible on the premise of ensuring that the heat exchanger 100 has strong heat exchange capacity and a longer defrosting period, and the heat exchanger 100 can be designed to be more compact.
In order to further prolong the defrosting period of the heat exchanger 100, a better value range of the k value can be effectively planned when the pipe diameter of the heat exchange pipe 110 is 4 mm-10 mm.
Referring to fig. 1 and fig. 3, in the second embodiment of the heat exchanger 100 of the present invention, when the pipe diameter of the heat exchange pipe 110 is between 4.0mm and 5.5mm, the heat exchanger 100 with different k values is tested continuously on the basis of the test of the first embodiment, and the test data is as follows:

(1) when the k value is 3.2-4.2, the heating capacity of the heat exchanger 100 is gradually enhanced, approximately 3643 w-3891 w, and the defrosting period is 65.5 min-77.5 min.
(2) When the k value is greater than 4.2, the heating capacity and the defrosting cycle of the heat exchanger 100 tend to be stable and have little difference, but the width of the fins 120 is relatively increased, which increases the cost of the heat exchanger 100.
In summary, in this embodiment, when D ∈ [4.0mm, 5.5mm ], the k value of the heat exchanger 100 is preferably 3.2 to 4.2, so that the heating capacity of the heat exchanger 100 is improved by 12.3% to 13.4%, and the defrosting cycle is prolonged by 52% to 57%. In addition, the cost of the heat exchanger 100 may also be reduced.

table 10. when the pipe diameter of the heat exchange pipe is 6.5mm, the heat exchanger test data table:
table 11. when the heat exchange tube pipe diameter was 7mm, the heat exchanger test data table:
from the data recorded in tables 8 to 11 above, the following can be analyzed for D ∈ (5.5mm, 7.0 mm):
(1) when the k value is less than 3.6, the heat generation capacity and the defrosting cycle of the heat exchanger 100 are less varied as the width of the fin 120 is increased.
(2) When the k value is 3.6-4.8, the heating capacity of the heat exchanger 100 is gradually enhanced, approximately 3720 w-4010 w, and the defrosting period is 69.1 min-84.5 min.
(3) With k greater than 4.8, the heat exchanger 100 has less heating capacity and cycle variation, but the fin 120 width is relatively increased, which increases the cost of the heat exchanger 100.
In summary, in this embodiment, for D ∈ (5.5mm, 7.0 mm), the k value of the heat exchanger 100 is preferably 3.6 to 4.8, so that the heating capacity of the heat exchanger 100 is improved by approximately 11.9% to 13.2%, and the defrosting cycle is prolonged by approximately 49% to 55%.
