DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0022] like Figures 1 to 6 In one embodiment of the high-efficiency and energy-saving low-temperature water radiator of the utility model shown, it includes a shell 1, a heat exchanger 2 connected to an external hot water source, an air outlet 11 and an air inlet 12 are provided on the shell 1, and the heat exchanger 2 includes at least two rows of horizontal tubes 21 arranged at intervals in a vertical position, and a connecting elbow 22 connecting two adjacent rows of horizontal tubes 21 to form a loop; a plurality of heat dissipation fins 23 are arranged at intervals on the horizontal tubes 21; the heat dissipation fins 23 are provided with a convex ridge 231 protruding outward on one side and a concave groove 232 on the other side. By designing the heat dissipation fins with grooves and convex ridges, a stable airflow channel for upward flow is formed in the absence of fan power, and the cold airflow is fully in contact with the heat dissipation fins when passing through the concave grooves, ensuring that the heat dissipation fins continuously and stably heat the airflow, and forming a stable fin plate surface, ensuring the strength of the heat dissipation fins, and reducing the risk of bending loss during transportation.

[0023] Specifically, the vertical surfaces of the heat dissipation fins 23 on two adjacent rows of horizontal tubes 21 are staggered; the vertical surfaces of the heat dissipation fins 23 are located in the gaps between adjacent rows of heat dissipation fins 23. By staggering the heat dissipation fins in two rows of vertical positions, the contact time between the airflow and the heat dissipation fins is increased while ensuring a smooth upward passage for the airflow, thereby increasing the heat exchange efficiency of the heat exchanger.

[0024] Specifically, the shell 1 includes a front panel 13 and a rear panel 14 arranged opposite to each other, and a left panel 15 and a right panel 16 arranged opposite to each other; both the left panel 15 and the right panel 16 are provided with protruding buckles 151; and the front panel 13 and the rear panel 14 are provided with slots that cooperate with the buckles 151.

[0025] Specifically, the air outlet 11 is provided with an air guide device 3; the air guide device 3 includes a plurality of spaced support seats 31, a plurality of spaced air guide plates 32 inserted on the support seats 31; the support seats 31 are provided with a plurality of slots 311 for inserting the air guide plates 32; and the housing 1 is provided with a flange 132 protruding toward the inner cavity to support the support seats 31 at one end of the air outlet 11. The air guide plates spaced and the support seats for inserting the air guide plates form an air guide device that can be quickly installed, which effectively improves the installation efficiency of the equipment.

[0026] Specifically, the slot 311 includes an insertion port 312 for the air guide plate 32 to enter, and a card cavity 313 arranged at the lower end of the insertion port 312; the air guide plate 32 includes a plate surface 321 and a card strip 322 arranged at the lower part of the plate surface 321 and slightly wider than the thickness of the plate surface 321.

[0027] Specifically, the heat dissipation fin 23 is provided with a convex ridge 231 and a groove 232 formed by punching with an octagonal punch. The heat dissipation fin 23 is provided with a tube sleeve that is inserted into the outer wall of the horizontal tube 21, and the groove 232 is arranged around the tube sleeve. The groove 232 is provided with a passage connecting the upper and lower sides of the heat dissipation fin 23. By punching the heat dissipation fin to form an octagonal ridge and groove, the strength of the heat dissipation fin is increased without increasing the material, and the loss of the heat dissipation fin caused by collision during transportation is reduced. The punched groove forms a bending channel connecting the upper and lower sides thereof, ensuring the smooth flow of airflow, and at the same time increasing the contact between the airflow and the heat dissipation fin, thereby increasing the heat exchange efficiency of the equipment.

[0028] Specifically, a plurality of strip-shaped protrusions 131 are disposed on the front panel 13 and the rear panel 14 .

[0029] Specifically, two legs 17 are provided at intervals at the bottom of the housing 1; the height of the legs 17 is 13 cm to 18 cm.

[0030] The vertical surfaces of the heat dissipation fins 23 on a row of horizontal tubes 21 are located in the gaps between the heat dissipation fins 23 in an adjacent row.

[0031] The front panel, the rear panel, the left side panel and the right side panel which are plugged in and matched with each other quickly form a chimney-like passage with upper and lower openings.

[0032] Working principle: The staff will move to the equipment installation location, connect the heat exchanger 2 with the external heat source through the pipeline, and the low-temperature water will circulate stably inside the shell 1, continuously heating the air inside the shell 1. The hot air will continue to circulate upward, and drive the external cold air to continuously enter the shell 1 from the air inlet 12 at the bottom. The shell 1 with openings at the upper and lower ends cooperates with the heated heat exchanger 2 to form a chimney-like channel, forming a continuous and stable hot air flow without fan power, ensuring the heat dissipation efficiency of the radiator, and by setting at least two rows of horizontal pipes 21 for heat exchange, fast In order to heat the cold air, the grooves 232 stamped on the heat sink fins 23 are used to bend and guide the airflow, which increases the contact time between the cold airflow and the heat sink fins 23, ensures the strength of the heat sink fins 23 without increasing the material, and reduces the risk of collision loss of the heat sink fins 23 during production and transportation. In addition, by vertically arranging a row of heat sink fins 23 in the gaps between another row of heat sink fins 23, the airflow is further bent and guided while ensuring the smooth rise of the airflow, thereby increasing the contact time between the airflow and the heat sink fins 23 and improving the heating efficiency of the equipment.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
