TECHNICAL FIELD

[0001] The present application relates to the field of heating radiators, in particular to a steel core die-casting aluminum alloy radiator. BACKGROUND

[0002] The heating radiator is a heating device mainly for heating. The heating pipe delivers warm flow to the radiator, and the radiator radiates the heat in the warm flow to the outside, thereby achieving the purpose of heating the room. The existing radiator is composed of a heating pipe and a heat dissipation fin, and a plurality of radiators are connected to each other to form a heating radiator.

[0003] In order to improve the heat conduction effect, the existing heating radiator replaces the original iron radiator with an aluminum alloy material, which is light in weight and improves the heat conduction effect. However, the strength of the aluminum alloy material is limited, and when the internal pressure is too high, there is a risk of explosion. At the same time, the fins of the existing heating radiator are mostly made of the same material, and the side close to the wall will directly deliver a large amount of heat to the wall. The wall is in contact with the outside air, causing the loss of warm air and increasing the waste of energy. At the same time, in order to ensure the heating effect, the air remaining in the heating radiator needs to be discharged regularly before use to ensure the heating effect. Therefore, in view of the above problems, the present application provides a steel core die-casting aluminum alloy radiator. SUMMARY

[0008] The outer side of the radiator is provided with a visible U-shaped pipe for monitoring the water level of the humidifying pipe, and the visible U-shaped pipe and the steel upper pipe are in communication with each other, and are used for exhaust treatment of the steel upper pipe.

[0009] Preferably, both ends of the riser sleeve are evenly pressure-cast with an upper cast aluminum joint and a lower cast aluminum joint, and the lower cast aluminum joint is fixedly connected to the steel lower pipe, and the upper cast aluminum joint is fixedly connected to the steel upper pipe, both sides of the front connecting piece and the rear connecting piece are vertically pressure-cast with a plurality of connecting fins, the arc-shaped fins are arranged below the surface fins, the surface fins and the front connecting piece are arranged vertically, and the back fins are arranged vertically to the rear connecting piece.

[0010] Preferably, one end of the visible U-shaped pipe is in communication with the connecting pipe, and the other end is fixedly connected with a multi-channel connecting piece in communication therewith.

[0016] 2. By making the front section fins and the rear section fins from materials with different thermal conductivities, more heat of the heating radiator is transported to the indoor through the front section fins, so as to improve the indoor temperature adjusting effect of the heating radiator, reduce the amount of heating temperature transported to the outside through the wall, and save energy to a certain extent;

[0017] 3. By fixedly connecting the humidifying pipe to the back fins and connecting the humidifying pipe and the external water source, the humidifying pipe is heated by the back fins, so that the water vapor is diffused into the indoor, thereby improving the indoor air humidity to a certain extent;
