Collector 14 and support frame 15 are formed whole by welding.Hot water inlet pipe 4 and handle 7,7 edge of handle are provided on top board 3
3 center symmetric setting of top board, the setting of hot water inlet pipe 4 use screw thread in 3 center of top board, hot water inlet pipe 4 and top board 3
Connection.
Heat exchange core is made of water segregator 12, heat exchanger tube 8, water collector 13, and water segregator 12 and water collector 13 distinguish fixing seal
It is arranged at 8 both ends of heat exchanger tube.
Water segregator 12 is set to heat exchange core one end, welds together with heat exchanger tube 8, water segregator 12 and top board sealing ring 6 are matched
It closes, forms water inlet airtight cavity with top board 3, play sealing function；It is close that this is introduced by the liquid that hot water inlet pipe 4 flows into
Closed chamber body, then flow into heat exchanger tube 8, keep the fluid flow for flowing into every heat exchanger tube 8 more uniform and stablize, increase heat exchange efficiency.
Water collector 13 is set to the other end of heat exchange core, welds together with heat exchanger tube 8, water collector 13 and bottom plate sealing ring 11
Cooperation forms water outlet airtight cavity with bottom plate 2, plays sealing function, the liquid in heat exchanger tube 8 can first be gathered in the closed chamber
Body, then flowed out via outlet pipe.
Heat exchanger tube 8 uses the good solid material of heat exchange property, and helical fin is welded on the outside of pipe, to increase heat-transfer surface
Long-pending and tube wall temperature increases heat exchange efficiency.
Hot water is dividedly led into heat exchanger tube 8 via hot water inlet pipe 4, water segregator 12 and converges in water collector 13 again and flow into hemisphere
Shape collector 14 is flowed out finally by 90 ° of elbows 9.
Two-end part is respectively arranged with heat-storing material replacement window 5 on 1 periphery of shell, and heat-storing material is by close to top board 3
The heat-storing material replacement window 5 at position loads, and is flowed out by the heat-storing material replacement window 5 close to 2 position of bottom plate.Replace heat exchange core it
Before, heat-storing material first is emptied from lower part heat-storing material replacement window 5, after the completion of heat exchange core replacement, then is replaced from top heat-storing material
Window 5 loads heat-storing material.It because heat-storing material replacement window 5 uses glass material, therefore replaces window and is alternatively arranged as inspection socket use, to look into
See heat-storing material filling situation and working condition.
Heat exchange core is attached by the external pressure that 3 edge bolt 10 of top board applies with top board 3 and bottom plate 2, is passed through
