Problems solved by technology

The heat exchange efficiency of these spiral coil heat exchangers is low, and it is difficult to meet the bathing environment with low ambient temperature in winter.
The design of the "Thin Plate Heat Exchanger" with patent number 01249608.1 is too complicated, using too many materials, but the effective heat exchange area cannot be increased accordingly, and the heat exchanger of this design is difficult to process and high in cost

Embodiment Construction

[0021] The heat exchanger of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] As shown in Figure 1, the core part of the heat exchanger designed in this embodiment is a piece of high thermal conductivity metal sheet made by stamping, forming a spiral groove from the inside to the outside (actually in the metal A metal plate 1 with spiral grooves is formed on both sides of the thin plate with grooves alternated between concavo-convex; by covering the metal plate 1 with the spiral grooves on the metal plate 4, the plastic plate 5 and the thermal insulation material (in the figure) Not shown), form mutually isolated upper layer helical fluid channel 2 and lower layer helical fluid channel 3 on both sides of the metal plate 1 of this band helical groove; The cold water inlet 6 at the edge of 2 flows in, and flows out through the clean water outlet 7 in the middle after being preheated, while the bathing waste w...

Abstract

The present invention relates to a novel plate type spiral heat exchanger, which has the characteristics of a plate heat exchanger, a spiral plate heat exchanger, and a spiral shell tube heat exchanger, and is characterized in that the size is small, the heat exchanging efficiency is high, the countercurrent heat exchange can be operated, the requirement of heat exchange in low temperature difference is met, a modular structure filter is provided, and a novel heat exchanger is easy to disassemble and clean, the present invention is easy for modularization process and assembly production, and the production cost is low. The present invention is particularly suitable for recycling of the after heat of bathing waste water and pre heating clean tap water in the process of household bathing, and more than 60 percent of waste heat can be effectively recycled, and the water heater power can be doubled in the condition of using lower cost and no energy consumption is added.

Description

technical field [0001] The invention relates to a new type of plate-type spiral heat exchanger, which has the characteristics of plate heat exchanger, spiral plate heat exchanger and spiral-coil heat exchanger, and especially relates to a small heat exchanger that only needs a small heat exchange area. device field. Background technique [0002] With the improvement of people's living conditions, more and more families have their own toilets and bathrooms, and more people take a bath in their own homes, of which showers account for a relatively high proportion. The water heaters currently available for household use include gas water heaters, electric water heaters, and solar water heaters. Household gas water heaters are mostly direct-heating instant water heaters, solar water heaters are mostly heat-storage water heaters, and the current mainstream of electric water heaters is heat-storage type, which is transitioning to direct-heating electric water heaters. [0003] Wh...
