Abstract
The utility model discloses a welding-free solar heat-absorbing plate core. The welding-free solar heat-absorbing plate core comprises a heat-absorbing plate (1). A group of copper pipes (2) is arranged on a plate surface at one side of the heat-absorbing plate (1) at intervals. The plate surface at the other side of the heat-absorbing plate (1) is provided with a heat-absorbing overlay film (4). The heat-absorbing plate core further comprises a heat-conducting plate (5) used for coating the copper pipes (2). Copper pipe surfaces of the heat-absorbing plate (1) and the heat-conducting plate (5) are respectively provided with a group of arc-shaped heat-absorbing grooves (6) and arc-shaped heat-conducting grooves (8) matching with the copper pipes (2) which are arranged in through holes formed by the corresponding heat-absorbing grooves (6) and the heat-conducting grooves (8). The heat-absorbing plate (1) and the heat-conducting plate (5) are connected via a group of corresponding fixing holes (9) arranged at two sides of the grooves. The copper pipes are clamped in the through holes formed by the arc-shaped grooves. The welding-free solar heat-absorbing plate core has following beneficial effects: thermal conduction performance is considerably improved by increasing heat conduction areas of the copper pipes; and the copper pipes are secured between the heat-absorbing plate and the heat-conducting plate by fixed connection between the heat-absorbing plate and the heat-conducting plate via the fixing holes, thereby avoiding the problem of insufficient solder resulting from conventional welding technology and leaving the heat-absorbing overlay film undamaged.
