According to the design calculation, each surface of a single heat exchange plate has 25 rows of ellipsoidal and spherical surfaces. In terms of water inlet and outlet, circular holes with a diameter of 60mm are set at the four corners, and sealing rubber belts with a thickness of 4mm are added to the edges of both sides of the plate. The novel hybrid spherical heat exchange plate has lower flow resistance and more complicated turbulent flow state. In addition, the design concept that the ratio of width to length approximates the golden ratio is adopted for the purely mixed spherical surface used for heat exchange.

Description

A hybrid spherical corrugated heat exchange plate

technical field

The utility model relates to a hybrid spherical corrugated heat exchange plate in the field of heat exchangers.

Background technique

A heat exchanger is an energy-saving device that enables two or more fluids at different temperatures to transfer heat between materials. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, making the fluid temperature reach the process Specified indicators to meet the needs of process conditions. The development of heat exchangers has penetrated into all aspects of people's lives, such as: air conditioning, HVAC, pressure vessels, water treatment equipment and so on. It can be said that the level of research and development of the heat exchanger industry directly reflects the level of scientific research and development of a country in terms of comprehensive energy utilization. Among the various types of heat exchangers, the plate heat exchanger has the advantages of high heat transfer coefficient, compact structure, low initial investment cost, small temperature difference at the end, and is suitable for heat transfer in various fluid media. occupy a place in the As the heat exchange plate is one of the most important components of the plate heat exchanger, its research level directly affects the heat transfer capacity of the plate heat exchanger. At present, the widely used heat exchange plates are herringbone corrugated heat exchange plates and horizontal flat corrugated heat exchange plates. Recently, a series of new corrugated heat exchange plates such as spherical discontinuous corrugated heat exchange plates have also appeared.

Contents of the invention

In order to improve the heat transfer coefficient of the existing heat exchange plate, reduce the flow resistance of the heat exchange fluid, and further improve its aesthetic appreciation value, the utility model provides a hybrid spherical corrugated heat exchange plate with an extremely uneven surface design. The overall heat exchange area of the heat exchange plate is greatly increased, and the heat exchange capacity is improved.

The technical solution adopted by the utility model to solve the technical problem is: make two kinds of mixed spherical corrugated designs on the rectangular plate (the length*width*height of the single plate is 829.18mm*370.82mm*0.5mm), one of which is An ellipsoid that satisfies the equation x ² /16+y ² /16+z ² /64=1 (unit mm), and the other is a spherical surface with a radius r=4 (unit mm). The ellipsoidal or spherical surfaces in the same row have the same concavity and convexity, and the left and right intervals are 1.2705 mm, and the number of the entire row is 40; the concavity and convexity of the adjacent upper and lower ellipsoidal surfaces are opposite to the spherical surface, and the head and tail are exactly on the same horizontal plane. According to the design calculation, each surface of a single heat exchange plate has 25 rows of ellipsoidal and spherical surfaces. In terms of water inlet and outlet, using the existing technology, circular holes with a diameter of 60mm are opened at the four corners of the heat exchange plate, and sealing rubber belts with a thickness of 4mm are added to the edges of both sides of the plate. heat mode. This kind of hybrid spherical corrugated heat exchange plate increases the heat exchange area to a certain extent compared with the previous horizontal flat corrugated plate, vertical corrugated plate, herringbone corrugated plate, etc. Heat plate, the new hybrid spherical heat exchange plate has lower flow resistance and more complex turbulence state, so it has more efficient heat exchange performance. In addition, further improvements have been made in the aesthetic application of the plate, and the design size of the mixed spherical surface purely used for heat exchange conforms to the golden ratio design concept.

The beneficial effects of the utility model are: to a certain extent, the heat exchange capacity of the existing plate heat exchanger is increased, and the aesthetic value of the traditional heat exchange plates is improved.

detailed description

In Figure 1, the thick black solid line is the rubber coil used to seal the heat exchange medium, with a thickness of 4mm. In practical application, a heat exchange medium flows in from the port A, passes through the flow channel, flows downward along the radial direction of the corrugation of the mixed spherical corrugated heat exchange plate, and finally collects through the flow channel and flows out from the port B; At the same time, another heat exchange medium flows in from C orifice, passes through the flow channel, flows upward along the radial direction of the hybrid spherical corrugated heat exchange plate on the other side, and finally gathers through the flow channel and flows out from D orifice . This counter-current heat exchange mode allows two heat exchange media with different temperatures to fully contact with each other through the heat exchange plate to realize heat transfer. At the same time, in terms of plate size, traditional Chinese aesthetic characteristics are incorporated, and the design size of the hybrid spherical surface purely used for heat exchange conforms to the golden ratio design concept.

Fig. 2 is a local situation of the mixed spherical corrugation of the new heat exchange plate, the heat exchange medium flows through the surface of the mixed spherical heat exchange plate to realize the heat transfer effect of the two fluids.
