Problems solved by technology
[0003] The heat exchanger generally used in the heat pump unit in the prior art is cylindrical, and the heat exchange tubes are arranged in the cylindrical shell along the length direction of the heat exchanger. Since the heat exchange tubes are long, the cold medium is introduced from the inlet. After the heat exchanger, it can only fully contact and exchange heat with the heat exchange tube near the area facing the inlet. The diffusion range of the cold medium is difficult to cover the entire length of the heat exchange tube, so it is difficult for the cold medium passing into the shell to communicate with The medium to be exchanged in the heat exchange tube will flow out from the outlet after fully contacting the heat exchange, which will make it difficult to increase the heat exchange efficiency of the heat exchanger and the entire unit to a higher level, resulting in lower energy utilization

The invention relates to a heat exchanger and heat exchange equipment. The heat exchanger comprises a shell (4) and a plurality of heat exchange tubes (14) arranged in the shell (4). The upper end of the shell (4) is provided with The gaseous refrigerant flow port (5), the lower end of the housing (4) is provided with a liquid refrigerant flow port (10), and also includes a gas baffle (11), the gas baffle (11) is located between the gaseous refrigerant flow port (5) and the most Between the heat exchange tubes (14) on the upper layer, a plurality of ventilation holes (19) are provided on the area of the gas baffle plate (11) that is not aligned with the gaseous refrigerant flow port (5). When the heat exchanger of the embodiment of the present invention is used as a condenser, the gaseous refrigerant can enter the shell more evenly and fully contact the heat exchange tubes to exchange heat, so as to improve the heat exchange efficiency of the heat exchanger, and can also prevent the gaseous refrigerant from The refrigerant directly impacts the heat exchange tube; when the heat exchanger is used as an evaporator, it can avoid the phenomenon of suction and liquid as much as possible.
Description
technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a heat exchanger and heat exchange equipment. Background technique [0002] At present, with the increasing shortage of energy, people pay more and more attention to the application of renewable energy. As the application equipment of renewable energy, the heat pump unit has been paid more and more attention by people. The heat pump unit is composed of a compressor, a condenser, a throttling device, an evaporator, a four-way reversing valve, and ancillary equipment. During the operation of the heat pump unit, cooling and heating coexist and rotate as needed. Therefore, the evaporation Both the condenser and the condenser need two functions of evaporation and condensation. [0003] The heat exchanger generally used in the heat pump unit in the prior art is cylindrical, and the heat exchange tubes are arranged in the cylindrical shell along the length direction of...
