Problems solved by technology

The heater made of 304 grade stainless steel has particularly strict water quality requirements, because 304 grade stainless steel is particularly sensitive to chloride ions in heating hot water using tap water, and it is inevitable to increase the concentration and activity of chloride ions in hot water evaporation. Devices are rarely made of 304 grade stainless steel

specific Embodiment approach 1

[0066] Such as figure 1 10m shown 2 The metal foil tube radiator with a strip structure for indoor heating is a structural radiator in which a bare structure radiator is placed in a shield as a core. It includes stainless steel foil pipe 1 and metal heat dissipation fins 2 as heat medium flow channels. The stainless steel foil tube 1 expands into the hole of the side panel 11a of the shield and the hole of the fin 2, forming the simplest structure of the shield, the fin and the tube.

[0067] The lower position of the radiator guard 5a is provided with an air inlet 6a, and the upper position is provided with an air outlet 8a and a grille 9a protruding from the metal foil tube 1 outside the guard side panel 11a, which is directly connected to the external piping system. The shield side panel 11a is provided with two symmetrical holes of 16.2 mm each, and the hole spacing is 80 mm corresponding to the holes of the fins 2 .

specific Embodiment approach 2

[0080] Such as figure 2 18m shown 2 The combined plate cover radiator for indoor heating is a luxurious structure assembled with shield and core separation. The metal foil tube 1 expands into the hole of the fin 2 to form an integrated structure to form a radiator core group. It consists of two or more bare structures. After the radiator is stacked up and down along the wind direction, the metal foil tubes 1 on both sides are respectively connected to the left and right sides into a channel through the connecting tube 3 . The connecting port 4 of the external pipe network system opened on the connecting pipe 3. The inlet and outlet of the radiator can be set on both sides respectively, also can be set on the same side, and can be set in any direction interface, so as to form the circulation of heat medium and working medium.

[0081] First take 2 stainless steel foil tubes 1 with a diameter of Φ15.8mm and a thickness d of 0.185mm, and arrange the fins 2 with opening holes a...

specific Embodiment approach 3

[0097] Such as Figure 9The metal foil tube heat sink with a coverless structure shown is made of metal plates with holes 17, hole flanges 18 and fins 2 evenly arranged on the metal foil tube with a thickness of 50-200 μm at a distance of 3-20 mm. 1, through the expansion tube interference combination into a shroudless radiator.

[0098] The third embodiment is suitable for heating in winter in buildings. Its heat dissipation methods include natural convection accounting for 80-95% and thermal radiation accounting for 5-20%.

Abstract

The invention discloses a radiator; a metal tube is a metal foil tube with the thickness of 50-200mum; a metal radiating fin is provided with an open draw hole with turned-over edges; the metal foil tube is swollen into the open draw hole with turned-over edges to form a whole with the metal radiating fins by interference and the metal radiating fins are arranged on the metal foil tube with the spacing of 3-20mm.The manufacturing method for the radiator comprises the following steps: according to diameter of the metal foil tube, manufacturing a metal plate with the thickness of 0.05-0.30mm into the open draw hole with turned-over edges and the height of 3-12mm and high density metal radiating fins with deeply pressed patterns; arranging the open draw hole fins with turned-over edges in a light protecting cap which encloses a metal radiator core; and pushing alloy expanding balls in the metal foil tube to generate interference expanding tube amount of 30-300mum to form tight coupling of finned pipes. The radiator has scientific design, light weight and high efficiency, obviously saves energy, decreases waste exhaust and saves raw materials and metal heat intensity coefficient is larger than 5.0w / kg.DEG C.

Description

technical field [0001] The invention relates to a radiator, in particular to a radiator and a manufacturing method thereof. Background technique [0002] The radiators used for heating in cold regions in winter mostly use the hot water in the heating bag to dissipate heat through the radiator fins for heating. Most of the materials are cast iron, steel, aluminum inner coating, steel-aluminum composite, or copper. Not only is the weight heavy, but the metal heat strength is low. [0003] There is a type of radiator with metal fins wound on stainless steel pipes or steel pipes, which adopts a structure that is welded on the pipes or penetrated into the fins and welded on the pipes. For example, the heating radiator disclosed in Chinese patent CN1201133A has poor corrosion resistance, stainless steel fins must be used for stainless steel welding, and reduction heat treatment must also be used, and thermal conductivity and heat dissipation are poor, no energy saving, large reso...
