Problems solved by technology

[0003] The invention aims at the fact that the traditional radiator has no reasonable strengthening of the heat transfer inside and outside the water pipe, and the internal and external heat transfer cannot be matched, which leads to the low heat transfer of the radiator under a given radiator appearance area, and the low cost of the traditional plate radiator. High and complex process and the heat exchange in the tube cannot be strengthened. A new type of high-efficiency plate-type low-temperature radiator is provided. The heat exchange plate is enhanced by a plate-like fine channel array with a specific structure and a large area is compounded on its plate surface. Heat exchange fins realize efficient heating function. Since the heat exchange area of ​​air outside the tube, convective heat transfer and heat transfer of liquid flow in the tube have been greatly improved, heating can be realized at low water supply temperature and the efficiency of the heating system can be realized. Energy saving and low cost

Embodiment Construction

[0032] The present invention will be described below in conjunction with the accompanying drawings.

[0033] The invention relates to a high-efficiency plate-type low-temperature radiator, such as Figure 1a , Figure 1b , Figure 1c and Figure 1d The perspective view, front view, left side view and top view of a preferred structure, including the plate-shaped fine channel array enhanced heat exchange plate 1 and the heat exchange fins 2 combined with the plate-shaped fine channel array enhanced heat exchange plate 1, the plate Thin channel array enhanced heat exchange plate 1 is a plate-shaped structure with more than two thin channels arranged side by side to form a thin channel array formed by extruding metal materials. The equivalent diameter of the thin channel is 4mm-10mm. And the ratio of the long axis to the short axis of the thin channel is 0.5-2.0, preferably 0.8-1.2, and the plate-shaped thin channel array reinforced heat exchange plate 1 has holes respectively c...

Abstract

The invention relates to an efficient plate-type low temperature heating radiator and a special assembly thereof. The efficient plate-type low temperature heating radiator comprises more than one sets of plate-type thin channel array enhancement heat transfer plates and more than one heat transfer fins; the plate-type thin channel array enhancement heat transfer plates are formed by extrusion forming of metal materials, and two or more thin channels arranged in parallel are formed in each plate-type thin channel array enhancement heat transfer plate to form a thin channel array plate-type structure; and one or more layers of heat transfer fins are stacked and compounded on the plate face of each plate-type thin channel array enhancement heat transfer plate, each heat transfer fin is provided with a plurality of air natural convection channels arranged in parallel, the periphery of each air natural convection channel is closed or opened, and the air natural convection channels are sequentially arranged in the plate length direction or the vertical direction of the plate-type thin channel array enhancement heat transfer plates. According to the efficient plate-type low temperature heating radiator and the special assembly, enhancement heat transfer is achieved through the plate-type thin channel array enhancement heat transfer plates, the large-area heat transfer fins are compounded on the plate faces of the plate-type thin channel array enhancement heat transfer plates, and therefore heating can be achieved at a low water supply temperature, and efficient energy saving and low cost of a heating system can be achieved.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation engineering, in particular to a novel high-efficiency plate-type low-temperature radiator and special components thereof. Background technique [0002] The water supply temperature of the current natural convection radiators is relatively high, and the heat dissipation area on the surface of the radiator is small. Once the water supply temperature drops, it cannot meet the requirements of the heating load. In addition to the heat source factors such as the difference between the water supply temperature and the heating temperature and the flow rate, the main factors restricting the heat transfer of the radiator are the external heat dissipation of the tube and the internal heat transfer of the tube. The amount of heat exchange depends on the surface area of ​​the heat exchanger, the efficiency of the fins, the temperature difference between the surface and the air, the smoothness o...
