Safe, efficient and parallel heat exchanger and application thereof

Abstract

The invention provides a safe, efficient and parallel heat exchanger. The safe, efficient and parallel heat exchanger comprises a refrigerant channel and a secondary refrigerant channel, the refrigerant channel and the secondary refrigerant channel are two independent metal pipelines, the cross section of each metal pipeline is at least provided with a straight side, the straight sides of two metal pipelines are close to each other, a gap is reserved between the straight sides of the two metal pipelines, the width of the gap is smaller than 1.5 mm, preferably, the width of the gap is smaller than or equal to 1.0 mm, and the interior of the gap is filled with a heat transfer medium layer. According to the safe, efficient and parallel heat exchanger, the design manner that in the past, a refrigerant channel and a secondary refrigerant channel are sleeved is changed, the refrigerant channel and the secondary refrigerant channel are independently arranged, the flat and long gap is reservedbetween the two channels to be filled with a heat transfer medium layer, due to the adding of the heat transfer medium layer, the refrigerant channel can be protected, and the breaking due to environment temperature effects can be avoided.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices for fixing tubular passage components, in particular to a safe and efficient parallel heat exchanger and the application of the safe and high-efficiency parallel heat exchanger. Background technique [0002] Heat exchangers used in condensers and evaporators in existing air-source or water-source heat pump water heaters, low-temperature heaters and water-cooled air conditioners usually use such as figure 2 The coaxial heat exchanger shown (the metal outer tube a1 and the metal inner tube a2 are socketed, the water heat transfer medium a4 flows in the metal inner tube a2, and the heat release or heat absorption is provided between the metal outer tube a1 and the metal inner tube a2 medium a3 flow), such as image 3 The cylindrical heat exchanger shown (commonly known as a high-efficiency tank, includes a cylindrical metal outer tube b1, and a brine channel b2 spirally coiled in the m...

Problems solved by technology

But in the actual working process, when the brine (water) is affected by the external environment temperature and freezes, it may burst the metal partition layer, causing the brine (water) and the refrigerant to mix, thereby making the air Source heat pump water heaters, low-temperature heating equipment or water-cooled refrigeration and air-conditioning equipment are water seeped and scrapped
