Problems solved by technology

Although the simple casing heat exchanger system is easier to seal, the heat transfer effect is poor and the refrigeration cycle is long
There are problems in the tubular type. It is difficult to add adsorbents, and there are many solder joints or sealing points in the system, which makes it difficult to seal the system.
Using a conventional shell-and-tube heat exchanger or a simple casing heat exchanger as adsorption / regeneration can improve the heat transfer effect, but there are certain difficulties in equipment processing, adsorbent installation, and system sealing maintenance.
If the fins are simply placed, there will be a large contact thermal resistance between the fins and the wall of the adsorber. If you want to use welding, it is difficult to weld in a pipe with a diameter of less than 300mm

Embodiment Construction

[0019] Such as figure 1 , 2 , 3, and 4, except for the space occupied by the inner radial heat transfer fins 5 and the inner longitudinal heat transfer fins, the blank space between the adsorber main body 6 and the porous tube 4 is the adsorbent installed. pass figure 1 It can be seen from the front view that the high-efficiency adsorber of the present invention utilizes a seamless pipe as the main body 6 of the adsorber, and uses a special processing technology to form grooves of a certain shape inside the seamless pipe as the inner radial fins 5 and inner longitudinal fins. 3 and the embedding groove of the outer fin 2. According to the size of the specific seamless pipe diameter, the inner and outer fins 2, 3, 5, flange 7, and flange cover 1 are processed for future use. Take a small seamless tube and punch small holes on it, the hole diameter is 2-5mm, and the hole spacing is 4-8mm. In order to prevent the adsorbent from entering the porous tube, a layer of 40-80 mesh s...

Abstract

The invention refers to gas and solid reaction field of chemistry absorption cooling, sun energy thermal storage and large quantity heat transmitting, accurately it is absorbing regenerator which is used to strengthen heat transmitting, it sets a multi-hole pipe in the centre of gapless rail, radial and lengthways vanes are set between small pipe and seamless rail, it fills sorbent in space isolated by radial and lengthways vanes.

Description

technical field [0001] The invention relates to the technical fields of chemical adsorption refrigeration, solar thermal storage and gas-solid reaction requiring large heat transfer, and more precisely relates to an adsorption regenerator for enhanced heat transfer. Background technique [0002] Adsorption refrigeration is a promising environment-friendly refrigeration method. It has no compressor, does not produce greenhouse effect gases, and does not destroy the ozone layer of the atmosphere, so it has been widely valued. However, due to the small thermal conductivity of the adsorbent, the heat transfer of the system is difficult. Even if there is an adsorption working medium pair with better adsorption performance, if the heat transfer problem is not solved, the cooling power is still very small (the refrigeration cycle is long). Since the system is required to be kept in an absolutely sealed state, the existing adsorption regenerators generally use conventional tube-and-...
