Abstract
The utility model relates to a cast iron sheet type radiator, which is indoor heating equipment. The radiator with high efficiency is improved from a traditional cast iron radiator according to the boundary layer heat transfer theory that the size of the heat-transfer efficiency is in inverse proportion of the height of the radiator. The appearance of the single sheet forms a cuboid shape. The outer surface of the single sheet is provided with a plurality of short wing-shaped ribs. Compared with the four post type cast iron radiator, the same quantity of material can increase 50% of heat-transfer efficiency. Under the condition of the equal heat dissipating capacity, the utility model can save 30% of the material. Because a body of the radiator is provided with a flange, the utility model is installed easily.
Description
The invention belongs to the heating system technical field, be specifically related to a kind of improvement of cast iron sheet-type radiator and the selection of physical dimension.
General heating radiator has the branch of steel and cast iron matter, with regard to the steel radiator, its advantage is the metal thermal intensity height, and outward appearance is good, but compare with cast-iron radiator, its corrosion resistant performance is poor, cost of manufacture height, and existing cast iron heat radiation, both made and be known as preferably that but there is heaviness in radiator, shortcomings such as floor space is big, and complexity is installed, and iron consumption amount is many.
The present invention is devoted to the improvement of existing cast-iron radiator structure, and carries out the choose reasonable of each size, provides a kind of profile impression good, and floor space is little, compares heat transfer efficiency with four post radiators and improves 50% novel chip cast-iron radiator.
Structural design of the present invention is to make the whole fin of traditional cast-iron radiator into shown in figure one many rows short limb type fin according to radiator heat transfer efficiency and its boundary layer heat transfer theory that highly is inversely proportional to, fin length is 20～60mm, highly be 30～50mm, thickness is 3.0～3.5mm, fin and radiator cavity are cast overall structure, the position of adjacent two row's fins is interlaced, to guarantee that cold air forms curve from bottom to top and flows.The inner chamber total height is 126mm, and wide is 25mm, is cast with a lateral partitions in the middle of the inner chamber, and two ends are the circular arch type of R12.5mm about the block board thickness 4mm, inner chamber.
Accompanying drawings the design's concrete structure.Accompanying drawing one, two, three is respectively its part elevation figure, A-A profile and side view, wherein:
1---the left end flange
2---the right-hand member flange
3---the top fin, 3 '---the bottom fin
4---the middle part fin
5---the top dowel, 5 '---the bottom dowel
6---cavity
7---dividing plate
The overall dimension of every sheet heat radiator is long * wide * high=492 * 101 * 150(mm), 14 kilograms of weight, area of dissipation 0.81m
2, Tsing-Hua University's Thermal Power Engineering be air conditioning labor test result Coefficient K=6.6 (kilocalories)/(time rice
2℃), metal thermal intensity q=0.37 (kilocalorie)/(time. kilogram. ℃), experimental pressure 13 kilograms per centimeter
2Its heat transfer property and four posts, 640 type cast-iron radiators relatively see the following form:
(experiment numbers: 8552,8554.Date: 85.11.5,85.11.16)
| Radiator of the present invention | Four posts, 640 type radiators | |
| Every heat | 348 kilocalories/hour | 90.9 kilocalorie/hour |
| The every gross area | 0.81 rice 2 | 0.2 rice 2 |
| Every weight | 14 kilograms | 5.84 kilogram |
| Heat transfer coefficient | K=6.6 kilocalorie/time. rice 2℃ | K=7 kilocalorie/time. rice 2.℃ |
| Metal thermal intensity | Q=0.37 kilocalorie/time kilogram ℃ | Q=0.24 kilocalorie/time. kilogram. ℃ |
Can reach a conclusion from above data, cast iron sheet-type radiator of the present invention heat transfer efficiency under equivalent material increases by 50% than four columnar radiators, if save material 30% under the equal heat dissipation capacity situation.
This kind radiator low cost is saved floor space obviously, and is in addition handsome in appearance, is applicable to the heating of house of building below 20 layers.
Claims (2)
1, a kind of cast iron sheet-type radiator, the architectural feature of radiator body is:
The outer surface of a, radiator is cast with the transversely arranged short limb type fin of longitudinal separation.
