Abstract
A kind of high-strength gray cast iron aerofoil profile inner chamber is without sand radiator, it comprises radiator shell, lumen of radiator and radiator blade, connector is had respectively at the upper/lower terminal of radiator shell, the front and back of radiator shell concaves, one deck resin protection film and several reinforcements are also had on lumen of radiator surface, its special character is, the front of lumen of radiator and the back side are that circular arc is connected with the junction of side; The outer diameter D of connector is 50 ~ 55 millimeters; Advantage is, changes the front of lumen of radiator and the back side into circular arc and is connected, increase the thickness of junction with the junction of side, and meanwhile, the load performance that circular arc connects is better, withstand voltage higher, effectively prevents the explosion of radiator; Increase the external diameter of connector, thus can process the screw thread of 1.2 inch or larger diameter, large diameter tube connector is installed, increase flow and the flow velocity of water, improve the radiating efficiency of radiator, solve the problem of large area house type chillout.
Description
Technical field
The utility model belongs to a kind of heating installation, and particularly a kind of high-strength gray cast iron aerofoil profile inner chamber is without sand radiator.
Background technology
Radiator of the prior art has many kinds, as aluminium alloy heat radiator, steel radiator and cast-iron radiator.The radiating rate of aluminium alloy heat radiator is fast, handsome in appearance, but aluminium cost is too high, and service life is short, cannot be accepted by users, therefore, is difficult to adopt on a large scale in architectural engineering.The amount of stored heat of steel radiator is less, easily rots to get rusty, complex manufacturing, and price is also higher, therefore, is also difficult to large-scale promotion and application.Cast-iron radiator has the advantages such as amount of stored heat is large, corrosion-resistant, production technology is simple, cheap, and thus extensive extensive use in architectural engineering, particularly cast iron wing-type radiator is most widely used.But cast iron wing-type radiator also has a lot of shortcoming, such as, inner chamber is comparatively large, and water capacity is many, thus consumes energy higher, and withstand voltage lower, and maximum working pressure (MWP) is only 0.6MPa, so, can not skyscraper be used for.Particularly radiator own wt is comparatively large, and metal material consumes more, and every sheet weight, up to 18 ~ 20kg, causes the huge wasting of resources.In addition, also leave over a large amount of remaining sand in the inner chamber of radiator, more than these, sand is very easy to blocking heating cycle system and metering heating device, thus cannot realize metering heating.Meanwhile, because volume is comparatively large, the space taken is also larger, is difficult to the requirement meeting energy-saving and emission-reduction.
Chinese patent ZL201120312512.3 discloses a kind of gray cast iron wing-type radiator with no sand in inner chamber; it is formed primarily of radiator shell, lumen of radiator and radiator blade; connector is respectively arranged with at the two ends up and down of radiator shell; the front and back of its radiator shell concaves; to reduce the volume of lumen of radiator, be also provided with one deck resin protection film and several reinforcements on lumen of radiator surface.It is little that it adopts resin inner core to cast out inner chamber, and inner chamber light is without the radiator of sand, substantially increases the thermal efficiency of radiator, reduces energy resource consumption.But also there is certain deficiency.Its main problem is: 1, the front of inner chamber and the back side are that square is connected with the junction of side, and junction intensity is poor, easily causes radiator to burst when pressure of supply water increases, and can cause very large loss to user.2, the external diameter of connector is less, be only 45 millimeters, therefore, can only process the screw thread of 1 inch, pipeline that can not be larger with diameter is connected, thus limit flow and the flow velocity of hot water, and the quantity of radiator is more, the resistance of hot water flowing is larger, and flow velocity and the flow of hot water are less, for large area house type, there will be the problem of chillout.
Summary of the invention
The purpose of this utility model overcomes prior art Problems existing, and the high-strength gray cast iron aerofoil profile inner chamber providing a kind of high strength, large discharge, the thermal efficiency high is without sand radiator.
The utility model comprises radiator shell, lumen of radiator and radiator blade; connector is had respectively at the upper/lower terminal of radiator shell; the front and back of radiator shell concaves; one deck resin protection film and several reinforcements are also had on lumen of radiator surface; its special character is; the front of lumen of radiator and the back side are that circular arc is connected with the junction of side, to increase the intensity of connecting portion, prevent connecting portion from bursting.
The outer diameter D of connector is 50 ~ 55 millimeters, so that the screw thread of processing larger diameter, installs the tube connector of larger diameter, increases discharge.
The utility model has the advantage of:
1, change the front of lumen of radiator and the back side into circular arc with the junction of side to be connected, increase the thickness of junction, meanwhile, the load performance that circular arc connects is better, withstand voltage higher, effectively prevents the explosion of radiator, avoids causing damage to user.
2, increase the external diameter of connector, thus can process the screw thread of 1.2 inch or larger diameter, large diameter tube connector is installed, thus increase the flow of water, improve the flow velocity of water, improve the radiating efficiency of radiator, solve the problem of large area house type chillout.

Fig. 3 is A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in drawings, the utility model comprises radiator shell 3, lumen of radiator 5 and radiator blade 6, and the lower end of radiator blade 6 and radiator shell 3 maintain an equal level, the upper end of radiator blade 6 higher than radiator shell 3, with increasing heat radiation area; Connector 1 is had respectively at the upper/lower terminal of radiator shell 3, the outer diameter D of described connector 1 is 50 ~ 55 millimeters, so that the screw thread of processing larger diameter, the tube connector of larger diameter is installed, namely on connector 1, process the screw thread of 1.2 inch or 1.5 inch, the tube connector of 1.2 inch or 1.5 inch is installed, increases flow and the flow velocity of water; The front and back of radiator shell 3 concaves, and to reduce the thickness of lumen of radiator 5, reduces the volume of lumen of radiator 5, reduces the water capacity of radiator, saves circulatory system water; Also have one deck resin protection film 2 and several reinforcements 4 on lumen of radiator 5 surface, the front of lumen of radiator 5 and the back side are connected for circular arc with the junction 7 of side, to increase the intensity of connecting portion, prevent connecting portion from bursting.
