Heat exchanger for bathing shower

Abstract

The present invention provides a heat exchanger for bathing shower comprising a heat exchanging slab and two sealing covers. The heat exchanging slab is extruded by alloy metal material into simple overall structure to reduce processing steps, total manufacturing cost and selling price. A close water circulation entirety with circulation directing means is created therein to improve heat exchanging efficiency and energy saving effect of the water heater. Thereby, purchasing intention of consumers is increased in consequence of satisfaction of the purchasing ability. Thus, not only the speed and range of the promotion is benefited, but also the environmental protection in energy saving and carbon reducing effect is expedited.

1 . A structure of a heat exchanger for bathing shower comprises a heat exchanging slab and two sealing covers such that one of the sealing covers is created with a water intake and a water outtake, wherein said heat exchanging slab, which is a flat planar cuboid extruded by alloy metal material, includes a flat top surface, a flat bottom surface, a front hatch, a rear hatch, two parallel upright flanks, a plurality of parallel water passages penetrated through between the front hatch and rear hatch such that each pair adjacent water passages is partitioned by a septum with a circulating bore created thereon in interlaced stagger manner, which means a bore in upper section of one septum and another bore in lower section of the other septum for each pair of adjacent septa; and each of two sealing covers respectively covers on the front hatch and rear hatch of the heat exchanging slab to closely seal all ends of the water passages in water-tight manner by welding way so that all the water passages together with septa and circulating bores form a close water circulation entirety. 
     
     
         2 . A structure of a heat exchanger for bathing shower as claimed in  claim 1 , wherein said alloy metal material is aluminum alloy, copper or copper alloy. 
     
     
         3 . A structure of a heat exchanger for bathing shower as claimed in  claim 1 , wherein said alloy metal material is replaced by synthetic non-metal compound material with heat conductivity. 
     
     
         4 . A structure of a heat exchanger for bathing shower as claimed in  claim 1 , wherein said flat planar cross section shapes of the heat exchanging slab and two sealing covers are adapted into cambered cross section shapes, wherein said cambered heat exchanging slab includes a cambered top surface, a cambered bottom surface with two water intakes and a water outtake beneath, a cambered front hatch, a cambered rear hatch, two flanks, a plurality of parallel water passages penetrated through between the front hatch and rear hatch such that each pair adjacent water passages is partitioned by a septum with a circulating bore created thereon in interlaced stagger manner; and each of two cambered sealing covers respectively covers on the front hatch and rear hatch to closely seal all ends of the water passages in water-tight manner so that all the water passages together with septa and circulating bores form a close water circulation entirety.
