Problems solved by technology
The circulation circuit of the refrigerating oil flowing together with the working medium in the heat collecting tube is therefore designed to be longer, which makes it difficult for the compressor unit to return oil and easily cause compressor failure
Therefore, it can only be applied to traditional solar energy systems, but cannot be applied to new solar energy systems that use phase change of working fluid to absorb heat.

Embodiment 1
[0027] Such as Figure 1-2 Shown is an integrally formed evaporative solar heat collector, which utilizes an extrusion process to process and form aluminum or aluminum alloy at one time. Including tube body 1 and heat absorbing fins 2. The heat-absorbing fins 2 are arranged along the radial direction of the tube body 1 and evenly distributed on the tube wall of the tube body 1 , which facilitates the heat exchange inside and outside the tube body 1 and promotes the full heat absorption of the working medium in the tube body 1 . The working medium inflow channel 11 and the working medium outflow channel 12 arranged coaxially with the pipe body 1 in the pipe body 1, the working medium flow in the working medium inflow channel 11 and the working medium outflow channel 12 are opposite to form convection, and the working medium inflow channel 11 The coaxial design with the working medium outflow channel 12 makes the heat-absorbing fins 2 on the tube wall and the working medium inf...

The invention relates to the technical field of solar heat collection, in particular to an integrally formed evaporative solar heat collector. The integrally formed evaporative solar heat collector comprises a tube body and heat absorption fins, wherein the tube body and the heat absorption fins are integrally formed by adopting an extrusion process, the pipe body comprises a working medium inletchannel and a working medium outlet channel which are coaxially formed, and the heat absorption fins are arranged on the surface of the tube wall of the tube body. In the technical scheme, the workingmedium inlet channel and the working medium outlet channel of a heat collecting tube are coaxially formed so that working media in the heat collecting tube can absorb heat of the tube wall, moreover,heat exchange is also carried out between the working medium flowing into the heat collecting tube and the working medium flowing out of the heat collecting tube, then the amount of the working mediawhich are needed under the same heat absorption area is greatly reduced, the working medium passage is shortened, and the situation that a compressor breaks down due to the fact that a circulating loop of frozen oil is too long is reduced.
Description
technical field [0001] The invention relates to the technical field of solar heat collection, in particular to an integrally formed evaporative solar heat collector. Background technique [0002] The evaporative solar heat collectors in the prior art generally require relatively complex processing techniques, such as copper tubes piercing aluminum sheets, inflation, etc., and the processing costs are high and the reliability is poor. [0003] The authorized announcement number is CN201779882U, and the utility model patent on March 20, 2011 discloses a new type of solar vacuum tube collector, which includes a glass tube and an aluminum wing. The aluminum wing is cylindrical, and the glass tube is wrapped in aluminum. The outer wall of the wing and the inner wall of the aluminum wing are integrally formed with a working medium heating pipe, and the upper end of the working medium heating pipe is connected to the header through a pipe joint. The working fluid heating pipe is i...
