Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides an integrated brazed plate heat exchanger with anti-thermal cracking and its production and manufacturing method, which solves the problem of constantly changing flow rate when the traditional heat exchanger is fed with liquid heat exchange medium. The heat medium directly impacts the heat exchange fins, which easily leads to damage to the heat exchanger and the impurities carried in the heat exchange medium are easy to form in the heat exchanger, resulting in a decrease in the heat exchange efficiency of the heat exchanger

Embodiment Construction
[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0038] see Figure 1-8, the present invention provides a technical solution: an integrated brazed plate heat exchanger for preventing thermal cracking, comprising a first outer plate 1, a second outer plate 2 and a heat exchange fin 3, one side of the first outer plate 1 A second outer plate 2 is provided, a number of heat exchange fins 3 are arranged between the first outer plate 1 and the second outer plate 2, and a side wall of the...

The invention discloses an anti-heat-crack integrated brazing plate heat exchanger and a production and manufacturing method thereof, and relates to the technical field of heat exchangers. The anti-heat-crack integrated brazing plate heat exchanger comprises a first outer side plate, a second outer side plate and heat exchange pieces; when a heat exchange medium passes through a first buffer mechanism, a first driving fan is pushed by the heat exchange medium to rotate, so that an inner spoiler can be driven to rotate; the flow of passing liquid is changed by changing the size of the right facing area of through holes in the inner spoiler and an outer spoiler, the situation that a high-flow-speed heat exchange medium directly impacts the heat exchange pieces is avoided, rotation of the inner spoiler in a buffer assembly drives the first driving fan to rotate through the heat exchange medium so as to drive the inner spoiler to rotate, an external power source is not needed, energy is saved, a filtering mechanism can filter out impurities in the heat exchange medium when the heat exchange medium is introduced, and the heat exchange medium can drive a second driving fan to rotate at the same time, so that a scraper and a cleaning brush clean and scrape the surface of a filter plate, and the surface of the filter plate can be kept clean.
Description
technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an integrated brazed plate heat exchanger for preventing thermal cracking and a manufacturing method thereof. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide application and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the floor area is one third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90% or more....
