Problems solved by technology

[0005] The two channels of a conventional plate heat exchanger often have separate channel inlet and exhaust ports, and have a certain diversion length, resulting in a large heat exchanger channel length, that is, the length of the gas passing direction, it is necessary to replace the The heat channel is divided into several parts, and the height of a single channel is reduced, thereby reducing the length of the guide part, or even omitting the guide part, which will cause a channel to have multiple intake and exhaust ports, so it is necessary to use an air distribution device Connect multiple intake and exhaust ports separately

Embodiment 1

[0081] Figure 30 , 31 And 32 are the application of the present invention to freezing and dehumidification, the air at state point 1 is first pre-cooled and dehumidified to become the air at state point 2, and then exchange heat with the fluid in the heat pipe such as cold water, refrigerant, etc. to be further dehumidified, and become state point 3 The air is then preheated to become the air at state point 4.

[0082] Here are the state points for a typical design:

[0083] 1: DB27℃, RH60%, D 13.4g / kg, H61.4 kJ / kg

[0084] 2: DB18.8℃, RH95%, D12.9g / kg, H 51.7 kJ / kg

[0085] 3: DB14℃, RH95%, D9.5g / kg, H38.0 kJ / kg

[0086] 4: DB24℃, RH51%, D 9.5g / kg, H 48.3 kJ / kg

[0087] The cooling capacity of the cold water or refrigerant in the present invention is: 13.7 kJ / kg, that is, the enthalpy difference from state point 2 to state point 3.

[0088] In the case of the same dehumidification capacity, that is, 3.9 g / kg, the cooling capacity of conventional refrigeration dehumi...

Embodiment 2

[0091] Figure 33-37 For the present invention is applied to solution dehumidification and regeneration, Figure 37 Combine dehumidification and regeneration. The solution 20 is arranged on the surface of the heat exchange plate.

Embodiment 3

[0093] Figure 38 ,39,40, for the case of dew point evaporative cooling, the air first passes through the dry channel, and then the air passes through the holes and passes through the wet channel in turn. There is water on the surface of the wet channel, and some air passes through the heat pipe to cool the fluid in the heat pipe, such as water. , At the same time, a part of the cold wind has to be blown. The unit can also make cold water only.

Abstract

The invention discloses a heat exchange structure which is composed of a thermal conductive plate, a sealing body, a sealing plate and tubes. The tubes penetrate through the thermal conductive plate, are connected with the thermal conductive plate and fix the thermal conductive plate. Two or more sealing bodies are arranged on the thermal conductive plate in a staggered mode, two or more separated channels are formed, ventilation areas are formed in the end portions of the channels, and the upper end and the lower end of the thermal conductive plate are sealed through sealing plates. According to the heat exchange structure, a plate heat exchanger and a tube fin type heat exchanger are combined to form the complex heat transmission structure, the advantages of the plate heat exchanger and the advantages of the tube fin type heat exchanger are utilized fully, the defects of the plate heat exchanger and the defects of the tube fin type heat exchanger are overcome, and the heat exchange structure has the advantages of being simple in structure, small in size, low in cost, small in manufacturing difficulty, wide in application range and the like.

Description

technical field [0001] The invention belongs to the field of heat transfer, in particular to a heat exchange structure. Background technique [0002] Plate heat exchangers are generally used for gas / gas heat exchange, such as sensible heat and total heat exchange in the air conditioning field, and tube-fin heat exchangers are generally used for gas-liquid heat exchange, such as surface coolers in the air conditioning field. These two heat exchangers are used. For example, in the field of dehumidification, the surface cooler is used to cool the air to the dew point for dehumidification, and the air / air heat exchanger is used to reheat the low-temperature air. At the same time, the air entering the surface cooler can be first Pre-cooling not only reduces the relative humidity of the supply air, but also reduces the cooling capacity. [0003] Plate heat exchangers generally use supports placed between the plates to form channels between the plates, while tube-fin heat exchange...
