Problems solved by technology

[0002] The spiral body of the existing spiral plate heat exchanger is made of two steel plates, forming two uniform spiral passages, the two passages are separated by a partition plate in the middle, and the upper and lower openings of the spiral passage are blocked by round steel or steel bars. Dead seal, the disadvantages are: there are two welds on the upper and lower openings of each channel, the welding volume is large, there are many leaks, the labor intensity is high, and the cost is high; leak due to corrosion

Embodiment Construction

[0010] refer to Figure 1-3 , it includes a helix, the helix is ​​made up of two helical plates 3 (steel plates), forming two uniform spiral passages, i.e. a refrigerant passage 8 and a heat medium passage 9, a partition 7 is arranged in the middle of the helix, and the two sides of the partition are respectively connected to The inner ends of the two spiral plates are welded and sealed to separate the refrigerant channel 8 from the heat medium channel 9. The refrigerant channel has a cold medium inlet 1 and a cold medium outlet 2, and the heat medium channel has a heat medium inlet 6 and a heat medium outlet 4. There is a bracket 5 below the helix, and the upper and lower edges of the two helical plates (steel plates) 3 that make up the helix are bent from the inside to the outside. The end face of the board is welded and sealed.

[0011] refer to Figure 4 , A reinforced sealing angle 10 is added at the angle between the spiral plate and the partition plate, and the reinfo...

Abstract

The invention relates to a spiral plate heat exchanger made of two steel plates through coiling and a production method thereof. The spiral plate heat exchanger is designed to mainly solve the problem of the existing spiral plate heat exchanger that the welding amount is large and the leakage points are in a large quantity. The upper edge and the lower edge of the two spiral plates for forming a spiral body are respectively bended outward and lapped on the end face of the adjacent spiral plate and then welded and sealed, and a strengthening seal angle is additionally arranged at the angle part between the spiral plate and a division plate. The production method comprises the following steps: coiling two pieces of steel plates into a spiral body, forming two uniform spiral channels, arranging a division plate in the middle of the spiral body, respectively welding and sealing the two edges of the division plate with the inner ends of the two spiral plates, bending the upper edge and the lower edge of the spiral plate of each channel of the spiral body outward and lapping the edges to the end surface of the adjacent spiral plate to be welded and sealed, and arranging a bracket under the spiral body. The spiral plate heat exchanger and the production method have the advantages that the welding amount is small, the leakage points are in a small quantity, and the production cost is low.

Description

Technical field: [0001] The invention relates to a heat exchange device used in metallurgy, chemical industry, petroleum, medicine, food and other industries, in particular to a spiral plate heat exchange device rolled from two steel plates and a production method thereof. Background technique: [0002] The spiral body of the existing spiral plate heat exchanger is made of two steel plates, forming two uniform spiral passages, the two passages are separated by a partition plate in the middle, and the upper and lower openings of the spiral passage are blocked by round steel or steel bars. Dead seal, the disadvantages are: there are two welds on the upper and lower openings of each channel, the welding volume is large, there are many leaks, the labor intensity is high, and the cost is high; Leakage due to corrosion. Invention content: [0003] The technical problem to be solved by the present invention is to provide a spiral plate heat exchanger with small welding amount, s...
