Description

Technical Field

[0001] The utility model relates to a heating radiator, in particular to a multi-tube die-casting aluminum heating radiator. Background Art

[0002] The heating radiator welds heat dissipation fins on the outside of the pipe. When the heating medium water flows through the pipe, the heat is transferred to the pipe through convection heat transfer, and then transferred to the external aluminum profile fins through the metal heat conduction of the pipe. The air flowing through the fins is then heated by the aluminum wing tube fins with a large heat exchange area to achieve the purpose of heating the room air temperature.

[0003] At present, the efficiency of the connection between the pipeline and the heat dissipation fin affects the overall production efficiency. At present, the pipeline and the heat dissipation fin are generally fixed by expansion and welding. For example, a heating radiator disclosed in the patent with application number CN200720191186.9 includes upper and lower header cross tubes, and a number of vertical pipes are welded between the upper and lower header cross tubes. The upper and lower header cross tubes are made of D-shaped steel pipes or copper pipes, and the vertical pipes are covered with machine-made aluminum profile pipes, and the aluminum profile pipes are provided with heat dissipation fins. In the heating radiator adopting the above technical solution, the upper and lower header cross tubes are made of D-shaped steel pipes or copper pipes, which can resist corrosion and ensure the service life of the radiator. The middle heat medium channel of the aluminum profile of the heat dissipation element adopts an elliptical structure with micro telescopic holes, which is welded between the upper and lower header cross tubes after expansion with the elliptical vertical pipe, and the vertical pipe is tightly combined with the heat dissipation aluminum profile.

[0004] The expansion-jointed and welded fixing structure used in the above patent requires that the pipes and the heat sink fins be produced separately during the production process, and then positioned for expansion-jointing. After the expansion-jointing, welding is also required, and the connection process is complicated and inefficient. Utility Model Content

[0005] Based on the disadvantages in the prior art that each heat dissipating fin in the radiator needs to be positioned and expanded, and then welded, which leads to a complicated connection process and low efficiency, the utility model provides a multi-tube die-cast aluminum heating radiator.

This solution is die-cast to die-cast part or all of the heat dissipation fins on the pipe unit, and then the pipe units are connected to form the entire pipe group as needed. It has the same heat dissipation unit structure and can be die-cast in batches, and does not require the positioning expansion and welding process of the heat dissipation fins, which greatly improves production efficiency and reduces production costs.

[0007] Preferably, the transverse tube has an internal thread, the internal threads of the two transverse tubes for connection are in opposite directions, and a connecting tube is provided between the two transverse tubes for connection, the connecting tube has two sections of external threads, and the two sections of external threads are in opposite directions. This solution connects the pipe units through the connecting tube, which is recyclable compared to the welding method, and the number of pipe units can be adjusted at any time according to needs.

[0008] Preferably, each connecting pipe has a hollow through hole, and the horizontal pipes on the left and right sides of the tube group form two liquid inlets and two liquid outlets to form a double-inlet and double-outlet structure. In this solution, the heat medium enters from the left and exits from the right, with a short stroke, which is suitable for large radiators with many tube units.

[0009] Preferably, each connecting tube has a hollow through hole, wherein the through holes of the odd-numbered connecting tubes from left to right on the upper side are provided with a partition to block the through holes, and the through holes of the even-numbered connecting tubes from left to right on the lower side are provided with a partition to block the through holes, and the horizontal tubes on the left and right sides of the tube body group form two liquid inlets and two liquid outlets, and one of the liquid inlets and one of the liquid outlets is blocked by a cover to form a single-inlet and single-outlet structure. In this solution, the liquid channels are alternated up and down, which increases the travel of the heat medium and is conducive to improving the utilization rate of heat.

[0010] Preferably, the transverse tubes between the two tube units are welded to form a tube group. This solution is a welding connection method, which has the advantages of stable connection and no leakage.

[0011] Preferably, first heat dissipation fins extending forward and backward are provided on the front and rear sides of the vertical tube.

[0015] Preferably, the third and fourth heat sink fins on the front side of the vertical tube have arc segments with the same center, and the side edges of the arc segments are connected to the first heat sink fins. The above heat sink fins are used to increase the heat sink area and improve the heat sink efficiency. In addition, the heat sink fins form a vertical heat sink channel, allowing cold air to enter from the bottom and exit from the top, which has the advantage of rapid heat exchange with the surrounding space.

[0016] Compared with the prior art, the advantages of the utility model are as follows: the utility model uses die-casting to die-cast part or all of the heat dissipating fins on the pipe unit, and then connects the pipe unit to form the entire pipe body group as needed.
