Heat radiator and its manufacturing process

Abstract

The invention relates to a heat radiator and a manufacturing process of the heat radiator. The heat radiator comprises a heat radiator panel, and a heat radiator backboard, and is characterized in that the heat radiator panel is a rectangular slot having a rectangular orthogonal projection and an antiparallelogram cross section and an antiparallelogram longitudinal section; the heat radiator backboard is a rectangular slot having a bottom face smaller than the bottom face of the heat radiator panel and an edge folding angle the same as the edge folding angle of the heat radiator panel, convex ribs are arranged in parallel at an equal interval on the bottom face of the heat radiator backboard, the heat radiator backboard is arranged in the slot of the heat radiator panel, the convex ribs of the backboard bottom face contact and are fixed together with the bottom face of the panel, and the rabbet edge of the heat radiator panel and the rabbet edge of the heat radiator backboard are combined together so as to form a heat radiator liquid channel in the heat radiator; and a water pipe is arranged in the heat radiator liquid channel and a heating medium is filled in the heat radiator liquid channel. Advantages of the invention include good appearance, practicability, safety and durability, high heat radiating efficiency, simple manufacturing process, and high efficiency. The invention is suitable for large-scale flow line production.

Description

Technical field: [0001] The invention relates to a radiator and a manufacturing process thereof, and belongs to the technical field of heating radiators. Background technique: [0002] The radiator commonly used in indoor heating systems is a steel plate radiator, which is relatively beautiful in appearance and easy to clean, and is welcomed by users. However, many problems have been exposed in use: 1. Because the internal water channel is narrow, the water resistance is large and easy to block; 2. Because the box body is made of two pressed plates and is welded together by resistance welding, because of its welding The strength of the seam (welded joint) is not high, and it is easy to collapse under the action of hot water pressure, causing water leakage; 3. The steel plate is thin, and it is susceptible to corrosion under the alternating action of the heat medium, causing water leakage; 4. The edges and corners are easy to hurt. In order to avoid hurting and beautiful, a beaut...

Problems solved by technology

However, many problems have been exposed during use: 1. Because of its narrow internal water channel, the water resistance is relatively large and easy to block; Seam (solder joint) strength is not high, it is easy to collapse under the action of hot water pressure, causing water leakage; 3, the steel plate is thin, under the alternating action of heat medium, it is easy to be corroded, causing water leakage; 4, there are cracks around the plate The edges and corners are easy to hurt people. In order to avoid hurting people and look beautiful, a beautifying protective cover is made around the plate, which increases the difficulty and cost of production.
