Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0025] see figure 1 A honeycomb gas cooler for a carbon dioxide heat pump provided by the present invention includes a honeycomb heat exchange unit body 5 in cross section and a carbon dioxide sleeve 7 sleeved at the center of the heat exchange unit body 5; wherein One end of the heat exchange monomer body 5 is the coolant inlet 3 , the other end is the coolant outlet 4 , one end of the carbon dioxide sleeve 7 is the carbon dioxide gas inlet 1 , and the other end is the carbon dioxide gas outlet 2 .

[0026] figure 1 It is the appearance diagram of the honeycomb heat exchanger. Its external shape is similar to that of a sleeve-and-tube heat exchanger, which is arranged in a spiral tube shape. This structure makes the gas cooler more compact and efficient. During the heat exchange process, carbon dioxide enters the heat exchanger from the carbon dioxide gas inlet 1,...

Abstract

The invention discloses a honeycomb type gas cooler for a carbon dioxide heat pump. The honeycomb type gas cooler comprises a heat exchanging monomer body and a carbon dioxide sleeve, wherein the cross section of the heat exchanging monomer body takes the shape of a honeycomb; the carbon dioxide sleeve is mounted in the center of the heat exchanging monomer body in a sleeving manner; a coolant inlet is formed in one end of the heat exchanging monomer body, and a coolant outlet is formed in the other end of the heat exchanging monomer body; and a carbon dioxide gas inlet is formed in one end of the carbon dioxide sleeve, and a carbon dioxide gas outlet is formed in the other end of the carbon dioxide sleeve. According to the honeycomb type gas cooler, the honeycomb type heat exchanging monomer body combines advantages of a microchannel heat exchanger and a double-pipe heat exchanger to overcome the defect that the traditional heat exchanger is not well matched with the carbon dioxide heat pump. A cold and hot fluid divider and a flow confluence device are positioned between a cold and heat fluid inlet and outlet and the heat exchanging monomer body, so that fluid uniformly and rapidly passes through a heat exchanger unit body. The honeycomb type gas cooler aims to improve the shortcomings of the traditional heat exchanger, fully utilize the property of the supercritical area of a carbon dioxide working medium, intensify heat exchange of the heat exchanger and improve the efficiency of the carbon dioxide heat pump.

Description

technical field [0001] The invention belongs to the technical field of heat pump equipment, and in particular relates to a honeycomb gas cooler for a carbon dioxide heat pump. Background technique [0002] As a device that consumes a small amount of electric energy to extract and utilize low-grade heat in the air, the air source heat pump has received more and more attention due to its environmental protection, energy saving, safety and convenience features. However, the refrigerants used in traditional heat pumps have the problems of damaging the environment, causing the hole in the ozone layer and the greenhouse effect, which have had a huge impact on people's production and life. Moreover, the stability and heating capacity of traditional working fluid heat pumps are limited under extreme weather conditions, so people must consider finding new refrigerants to meet the requirements for work efficiency and environmental protection. CO using natural refrigerant carbon dioxi...
