Problems solved by technology

[0002] The two-way heat exchange heater has patents for this concept and structure protection in the early years, because it has the characteristics of two-way heat exchange, which can make the heater have many advantages such as high thermal efficiency, small leakage current, long life, small size, etc., but it is different from the traditional The production of the one-way heat transfer heating tube is completely different, and is limited by technical methods and equipment, so the production of two-way heat transfer heaters has not been well realized so far.
Even if sample production can be carried out, due to the large number of welding positions, the welding qualification rate is very low, and the production cost remains high, which limits its popularization and application in water heaters and water heaters

Embodiment 1

[0048] Such as figure 1 and figure 2 Shown, the manufacturing method of described two-way heat exchange heater, concrete steps are as follows:

[0049] Step 1, such as image 3 and Figure 4 As shown, the outer tube assembly is made:

[0050] Step 1.1, making the outer tube: take the round tube of the required specification, cut it according to the required length, and after the inner and outer burrs are processed on the round tube, the two ends of the round tube are respectively punched by cold stamping to obtain through holes and Lower the through hole to get the outer tube 201;

[0051] Step 1.2, making the head: take the sheet material of the specification and punch it by blanking, and then use the forming die to make the head, or take the thick-walled tube of the specification and cold cut it into a blank of the required thickness, and then use the forming die to cold form The head 202 is made, the head 202 is U-shaped, and is recessed toward the middle end of the a...

Embodiment 2

[0066] Such as figure 1 and figure 2 Shown, the manufacturing method of described two-way heat exchange heater, concrete steps are as follows:

[0067] Step 1, such as image 3 and Figure 4 As shown, the outer tube assembly 2 is made:

[0068] Step 1.1, making the outer tube: take the round tube of the required specification, cut it according to the required length, and after the inner and outer burrs are processed on the round tube, the two ends of the round tube are respectively punched by cold stamping to obtain through holes and Lower the through hole to get the outer tube 201;

[0069] Step 1.2, making the head: take the sheet material of the specification and punch it by blanking, and then use the forming die to make the head, or take the thick-walled tube of the specification and cold cut it into a blank of the required thickness, and then use the forming die to cold form Made into a head 202;

[0070] Step 1.3, assembly of the outer tube and the head: insert th...

Abstract

The invention discloses a manufacturing method of a two-way heat exchange heater. The manufacturing method of the two-way heat exchange heater comprises the following steps that the step 1, an outer pipe assembly is manufactured; the step 2, a connecting pipe assembly is manufactured; the step 3, a two-way heat exchange heater body is manufactured; the step 4, the humidity is removed, and a ceramic insulation head is installed; the step 5, a connecting assembly is installed; the step 6, a pipe head and a temperature controller support are welded; the step 7, leakage detection of a product is conducted; the step 8, a terminal sheet is welded and fixed; and the step 9, laser marking of the required technical parameters is conducted. The manufacturing method of the two-way heat exchange heater has the advantages that the product quality is improved, the production cost is reduced, various working procedures are independent and have no interference with each other, and the manufacturing technology is simple.

Description

technical field [0001] The invention relates to the field of heater manufacturing, in particular to a manufacturing method of a bidirectional heat exchange heater. Background technique [0002] The two-way heat exchange heater has patents for this concept and structure protection in the early years, because it has the characteristics of two-way heat exchange, which can make the heater have many advantages such as high thermal efficiency, small leakage current, long life, small size, etc., but it is different from the traditional The production of the one-way heat transfer heating tube is completely different, and is limited by technical methods and equipment, so the production of the two-way heat transfer heater cannot be well realized so far. Even if the sample production can be carried out, because there are many welding positions, the qualified rate of welding is very low, and the production cost remains high, which limits its popularization and application in water boile...
