technical field

The utility model relates to heating equipment, in particular to a finned tube radiator.

Background technique

The heat source of terminal equipment for home heating is generally urban central heating, self-built boiler rooms in residential areas, household wall-hung boilers, etc., which emit heat through heat conduction, radiation, and convection to increase the temperature of the room.

Among the radiators, finned tube radiators are widely used at present. The heat dissipation area can be enlarged and the heat exchange effect can be enhanced through the fins. However, the radiator type of the finned tubes and the setting of the finned tube parameters all affect the cooling effect. Good or bad, and in the current energy crisis, it is necessary to save energy and meet the sustainable development of society. Therefore, it is necessary to develop a new finned tube, and at the same time, it is necessary to optimize the structure of the finned tube to achieve heat exchange. Maximize efficiency and achieve the goal of environmental protection and energy saving.

In view of this, the utility model is proposed.

Utility model content

The purpose of this utility model is to propose a finned tube radiator for the above-mentioned existing problems. This utility model has a larger heat dissipation than a simple steel column radiator. Finned tubes are parallel to the inlet and outlet pipes, heat medium water enters the horizontal column tubes, and then enters the finned tubes through the vertical column tubes, and the cold air is blown from the bottom through the finned tubes to the In the indoor space, directional convection is formed, and the wall surface will not be blackened; the utility model is more beautiful than a simple finned tube radiator, and does not need to install an outer cover, and the heat dissipation is more direct.

The finned tube radiator provided by the embodiment of the utility model includes: a horizontal column tube and a vertical column tube; the horizontal column tube and the vertical column tube are square structures, and a circular water channel is arranged in the center; the upper and lower ends of the vertical column tube are connected with the horizontal column tube, The horizontal column tube is provided with a water inlet and a water outlet.

The water inlet is set on the left side of the upper horizontal column tube, and the water outlet is set on the left side of the lower horizontal column tube. This setting is conducive to the complete entry of the heat medium into the radiator and ensures the heat exchange effect. The square structure is beneficial to enhance the overall mechanical strength of the radiator. The circular water channel inside the column tube facilitates the circulation of the heat medium inside the radiator and reduces the fluid flow resistance.

Preferably, there are two horizontal column tubes arranged up and down, and two vertical column tubes are arranged vertically.

The horizontal column tube and the vertical column tube constitute the main frame structure of the radiator, and other pipes are connected through the frame column tube to form a total heat dissipation system.

Preferably, equidistant U-shaped tubes are connected to the outside of the horizontal column tube.

Equidistant U-shaped tubes are set on the outside to form a semi-elliptical heat dissipation system for the radiator as a whole, and the gaps between the tubes can be more conducive to the circulation of air. On the one hand, it plays a role of heat preservation on the periphery of the heat surrounded by the finned tubes in the middle of the radiator, and on the other hand, it can also improve the aesthetics of the radiator.

Preferably, finned tubes are arranged horizontally between the column tubes.

Usually, fins are added on the surface of the heat exchange tube to increase the outer surface area of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency.

Preferably, the outer wall of the fin tube is wound with helical fins.

As for the length of the fins, if it is too long, it is because the heat of the base tube cannot reach the end of the fins in time or even if the effect is not obvious, if it is too short, the expanded heat transfer area is too small to achieve a good heat exchange thermal effect, so the height of the fins also has an optimum value. The set of spiral fins can form a uniform distribution gradient of heat transfer, which improves the stability of heat transfer.

Preferably, the finned tubes are arranged equidistantly.

The equidistant arrangement makes the heat exchange effect more uniform.

Preferably, deflectors are provided on the sides of the fins.

The cold air is heated by the finned tubes from the bottom and blows to the indoor space through the deflector, forming directional convection without blackening the wall.

Detailed ways

Embodiments of the present utility model will be described in detail below in conjunction with examples, but those skilled in the art will understand that the following examples are only used to illustrate the utility model, and should not be considered as limiting the scope of the utility model. Those who do not indicate the specific conditions in the examples are carried out according to the conventional conditions or the conditions suggested by the manufacturer. The reagents or instruments used were not indicated by the manufacturer, and they were all conventional products that could be purchased from the market.

Example 1

The embodiment of the utility model provides a finned tube radiator, the specific structure of which is shown in FIG. 1 . Including: horizontal column tube 1 and vertical column tube 6; horizontal column tube and vertical column tube are square structures, with a circular water channel in the center; the upper and lower ends of the vertical column tube are connected with the horizontal column tube, and the horizontal column tube is provided with water inlet 7 and water outlet 5.

The water inlet is set on the left side of the upper horizontal column tube, and the water outlet is set on the left side of the lower horizontal column tube. This setting is conducive to the complete entry of the heat medium into the radiator and ensures the heat exchange effect. The square structure is beneficial to enhance the overall mechanical strength of the radiator. The circular water channel inside the column tube facilitates the circulation of the heat medium inside the radiator and reduces the fluid flow resistance.

Two horizontal column pipes arranged up and down and two vertical column pipes arranged vertically constitute the main frame structure of the radiator, and other pipes are connected through the frame column pipes to form a total heat dissipation system.

Equidistant U-shaped tubes 3 are arranged on the outside of the horizontal column tube to form a semi-elliptical heat dissipation system for the radiator as a whole, and the gaps between the tubes can be more conducive to the circulation of air. On the one hand, it plays a role of heat preservation on the periphery of the heat surrounded by the finned tubes in the middle of the radiator, and on the other hand, it can also improve the aesthetics of the radiator.

The finned tubes arranged horizontally between the column tubes are usually finned on the surface of the heat exchange tubes to increase the outer surface area of the heat exchange tubes, thereby achieving the purpose of improving heat exchange efficiency.

The outer wall of the fin tube is wound with spiral fins 2. As for the length of the fin, if it is too long, the heat of the base tube cannot reach the end of the fin in time or the effect is not obvious even if it is achieved. If it is too short, Then the extended heat transfer area is too small to achieve a good heat transfer effect, so the height of the fins also has an optimal value. The set of spiral fins can form a uniform distribution gradient of heat transfer, which improves the stability of heat transfer.

Equidistantly arranged finned tubes make the heat exchange effect more uniform. The cold air heated by the finned tubes from the bottom is blown to the indoor space through the deflectors 4 arranged on the side of the fins, forming directional convection without blackening the wall.

While particular embodiments of the invention have been illustrated and described, it should be appreciated that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
