Description

Technical Field

[0001] The utility model relates to the technical field of gas water heaters, in particular to a heat exchanger heat absorbing sheet. Background Art

[0002] The heat exchanger is the core component of the gas water heater, which heats the water in the coil by absorbing heat through the heat absorbing sheet, thereby achieving heat exchange. The heat absorbing sheet in the heat exchanger is the fin. For the existing fins used in the heat exchanger, there are still the following areas for improvement: First, when the fins are in contact with the flue gas to achieve heat transfer, the smoke resistance of the fins themselves is weak, so the smoke will disperse faster. Then, when the flue gas flow rate is too fast, the exhaust temperature will be higher, which is obviously not conducive to heat absorption and heat transfer, and thus the comprehensive heat conduction efficiency of the heat exchanger will be low.

[0003] Therefore, a heat absorbing sheet with a flow guide component is proposed in the patent with publication number CN208983914U, and a V-shaped flow guide plate is arranged between two adjacent mounting holes, and the flow guide plate includes a left plate and a right plate connected in sequence, and the left plate and the right plate are both perpendicular to the heat absorbing sheet body, and one end of each is connected to the heat absorbing sheet body. The utility model guides the heat flow that originally directly flows upward to the surrounding of the heat absorbing tube, which is beneficial to the heat exchanger to absorb heat, improve the heat absorption efficiency of the heat exchanger, and reduce energy loss.

[0004] However, the V-shaped guide plate of the heat absorbing plate simply hinders the flow disturbance of the smoke, and the range of disturbance is limited to the plane of the guide plate and the nearby position, and the range of disturbance is limited. Utility Model Content

[0005] The utility model aims to provide a heat exchanger heat absorbing plate to solve the technical problem that the disturbance range of the guide plate of the existing heat absorbing plate is limited to the plane of the guide plate and the vicinity, and the disturbance range is limited.

[0006] The embodiments of the present invention are implemented by the following technical solutions:

[0007] A heat exchanger heat absorber comprises a heat absorber body and a plurality of mounting holes arranged on the heat absorber body for mounting pipes, a V-shaped convex rib group for guiding flow is arranged between the mounting holes, and the V-shaped convex rib group further comprises a diversion block and a diversion rib for diverting flow at an opening of the V-shaped convex rib group.

[0008] Preferably, both ends of the heat absorbing sheet body are also provided with folded edges for blocking smoke.

[0009] Preferably, a trapezoidal convex rib for guiding and spoiling flow is provided between the mounting hole and the folded edge.

[0010] Preferably, a plurality of groups of louvers penetrating the heat absorbing sheet body for circulating turbulent smoke are provided between the ribs of the trapezoidal ribs and the ribs of the V-shaped rib group.

[0011] Preferably, the diverter ribs are provided in two groups to guide the smoke on both sides after diversion by the diverter block.

[0012] Preferably, the heat absorbing plate body is also provided with a guide hole for positioning.

[0013] Preferably, the mounting hole is provided with a plurality of groups of positioning holes for positioning the pipeline.

[0014] Preferably, both sides of the heat absorbing plate body are further provided with wave-shaped cutouts for decelerating smoke turbulence, and the V-shaped rib group and the mounting holes correspond to the crests and troughs of the cutouts on one side, respectively.

[0015] By adopting this technical solution, the diverter block and the diverter convex ribs can further decelerate the flue gas by diverting and converging the flue gas before the flue gas is guided and disturbed by the V-shaped convex rib group, so that the flue gas disturbance effect is better, the flue gas disturbance range can be enlarged, the flue gas flow velocity can be reduced, and the heat exchange efficiency of the heat exchanger can be improved;

[0016] At the same time, the smoke on the back side of the heat absorbing plate body flows through the louvers under the V-shaped convex rib group. While the plane is disturbed, the smoke flow velocity on one side of the V-shaped convex rib group changes, which causes the air pressure change with the smoke on the back side. The smoke flowing through the louvers balances the air pressure, thereby expanding the range of smoke disturbance.

[0017] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0018] 1. The utility model uses the diverter block and the diverter ribs to further decelerate the flue gas by diverting and converging the flue gas before the flue gas is guided and disturbed by the V-shaped rib group, so as to achieve a better flue gas disturbance effect, expand the flue gas disturbance range, reduce the flue gas flow rate, and improve the heat exchange efficiency of the heat exchanger;

[0019] 2. The utility model simultaneously circulates the smoke on the back side of the heat absorbing plate body through the louver. While the plane is disturbed, the smoke flow velocity on one side of the V-shaped rib group changes, which causes the air pressure change with the smoke on the back side. The smoke flowing through the louver balances the air pressure, thereby expanding the range of smoke disturbance. BRIEF DESCRIPTION OF THE DRAWINGS
