Abstract

The invention discloses a heat exchanger with heating and cooling functions and a control method thereof. The heat exchanger comprises a fixing frame, a refrigerating pipe, a connecting pipe, a heater and fins, wherein the refrigerating pipe and the connecting pipe are respectively mounted on the fixing frame; the heater is mounted in the connecting pipe; and the refrigerating pipe is integrally connected with the connecting pipe through the fins. According to the heat exchanger, the refrigerating pipe and the connecting pipe with the heater which independently work respectively are connected by adopting the fins, and heat is transferred through the fins between the refrigerating pipe and the connecting pipe, so that the heat exchange area is enlarged and the heat exchange capacity is increased; and air can be also pre-cooled in a refrigeration mode, so that the frosting speed of the refrigerating pipe is reduced and the running reliability and stability of a product are improved. The heat exchanger is simple and compact in structure, simple to assemble and lower in cost; and meanwhile, the heater is mounted in the connecting pipe, so that the damage to surrounding materials caused by overheating of the heater is reduced and the safety and the reliability of the product are improved. Therefore, the heat exchanger has good application value.

Description

technical field [0001] The invention relates to a multifunctional heat exchanger, in particular to a heat exchanger with cooling and heating functions and a control method for cooling and heating of the heat exchanger. Background technique [0002] With the development of society, people's living standards are improving day by day, display cabinets with display effect are more and more widely used, but the traditional display cabinets only have refrigeration function, which cannot meet the multi-layer requirements of the people. In order to solve this problem, the Chinese patent application No. 200810138667.2 announced a multifunctional heat exchanger. This patent provides a heat exchanger that can solve the dual functions of cooling and heating. The cooling and heating systems of the heat exchanger are independent of each other and do not interfere with each other. Similar to this principle, At present, heat exchangers similar to this principle are more and more applied to ...
