Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a fractal microchannel heat exchanger. Background Technique

[0002] A microchannel, also known as a microchannel heat exchanger, is a heat exchanger with an equivalent channel diameter of 10 - 1000 μm. There are dozens of fine channels in the flat tube of this heat exchanger, which are connected to circular headers at both ends of the flat tube. A partition is arranged in the header to divide the heat exchanger channels into several processes. The materials that can be selected for the micro - microchannel heat exchanger are: polymethyl methacrylate, nickel, copper, stainless steel, ceramics, silicon, Si3N4, aluminum, etc. Compared with conventional heat exchangers, the microchannel heat exchanger not only has a small volume, a large heat transfer coefficient, and high heat transfer efficiency, can meet higher energy efficiency standards, but also has excellent pressure resistance performance and can use CO2 as a refrigerant.

[0003] Microchannel heat exchangers can be divided into micro - microchannel heat exchangers and large - scale microchannel heat exchangers according to their external dimensions. The micro - microchannel heat exchanger is a type of heat exchanger with a compact, light and efficient structure designed to meet the needs of the development of the electronics industry. Its structural forms include flat plate cross - flow micro heat exchangers and sintered mesh porous micro heat exchangers. With the improvement of micro - processing technology, high - efficiency micro heat exchangers with a flow channel depth range of several micrometers to several hundred micrometers can be processed.

[0004] In a fractal microchannel heat exchanger disclosed in the Chinese utility model patent application publication specification CN 2162134 U, it includes: a fan - shaped heat exchange box and a box cover. The fan - shaped heat exchange box includes a box body, a fan - shaped fractal unit channel, a liquid outlet pipe and a jack. A fan - shaped fractal unit channel is arranged in the inner cavity of the box body. A liquid outlet pipe is arranged on one side wall of the box body, and a jack corresponding to the liquid outlet pipe is arranged on the other side wall of the box body; the box cover is arranged on the top of the fan - shaped heat exchange box. The box cover includes a cover plate, a fluid inlet and a clamping edge. A fluid inlet is opened on the cover plate, and a clamping edge is arranged at the contact position between the cover plate and the fan - shaped heat exchange box, which can change the splicing form of the fan - shaped heat exchange box according to the space size of the actual use position, so that it can work in different - sized spaces and is used for chips in narrow spaces.

[0005] However, this device does not set up a circulating cooling mechanism. The construction and maintenance costs of common cooling and condensing devices are relatively high, the cooling efficiency is low, the consumption of water resources is large, and the pressure on the environment is large. This device does not set up a diversion device, the fluid distribution is uneven, which may cause scale formation inside the heat exchanger, resulting in a reduction in heat transfer efficiency.
