Abstract
The utility model discloses a combined type heat exchanger comprising an electrical heating component and a water container component which can be flexibly split. Electrical heating components with different power can be replaced according to the requirements of customers for different power, and can have the damaged components conveniently replaced upon damage instead of being replaced as a whole, thereby saving the resources. When in use, the heat exchanger with the structure provided by the utility model has simple structure and high safety performance, easily satisfies the personalized power requirements of the customers, and achieves convenient maintenance and better sanitation, thereby being suitable for various instant heating type electric water heaters, instant heating type electric heating taps, etc.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of unitized exchanger of electric heater.
Background technology
The instant electric water heater is accepted by increasing people owing to have than more power saving and plurality of advantages such as can use, not waste at any time of storage-type electric water heater.Commercially available instant electric water heater adopts the shell-and-tube heat exchanger (as shown in Figure 1) that large power, electrically heating tube 1 is directly immersed water receptacle 2 usually at present.This structure electric heating tube surface is scaling and have Danger Electric shock risk easily.For solving above-mentioned drawback, someone has made a kind of monoblock type heat exchanger as shown in Figure 2, it is peripheral and do not contact with electric heating tube 1 that hollow tubular water receptacle 2 is wrapped in electric heating tube 1, be filled with Heat Conduction Material 3 between water receptacle 2 and electric heating tube 1, water receptacle 2, electric heating tube 1 and Heat Conduction Material 3 are made an inseparable integral body by modes such as castings.But still there is following drawback in the heat exchanger of this structure: the personalized power demand that 1, can't satisfy the client; 2, in case damage just necessary integral replacing, the high and not environmental protection of maintenance cost.
The utility model content
At the prior art deficiency, the utility model is special to propose a kind of simple in structure, safe and efficient, the individual demand that can satisfy the client and the environment-friendly type unitized exchanger of maintenance easily.
Unitized exchanger comprises electric heating assembly and water receptacle assembly, and the water receptacle assembly is provided with current and imports and exports and water stream channel, and described electric heating assembly and water receptacle assembly can split flexibly.
The utility model can also be that described electric heating assembly is made up of heater element and the good heat conduction base of heat conductivility.
The utility model can also be that described heat conduction base is made of aluminum or copper.
The utility model can also be that described electric heating base is by mode and integral body of combining closely of heater element formation such as casting or riveted joint, solderings.
The utility model can also be that the quantity of described electric heating assembly is 1 to 8.
The utility model can also be that described water receptacle assembly is tubular and is fixed on the electric heating assembly outside, is provided with the water stream channel around shape in its barrel.
The utility model can also be, described water stream channel is spiral hollow pipe, and its surface is at least partly or entirely covered by the good heat carrier of heat conductivility.
The utility model can also be that described water receptacle assembly and heat carrier are made an integral body by modes such as casting or solderings.
Compared with prior art, the invention has the beneficial effects as follows: the structure that adopts electric heating assembly and water receptacle assembly to split flexibly, can satisfy the different power demand of client according to the electric heating assembly that client's needs are changed different capacity, also can change the damage parts during damage easily and not need integral replacing, economize on resources.
Owing to the utlity model has above-mentioned advantage, use the heat exchanger structure of the utility model structure simple, the security performance height satisfies client's personalized power demand easily, and easy to maintenance much cleaner, first-class applicable to various instant electric water heaters, the instant electric fire hose.
