Description
Technical Field
The utility model belongs to the field of heat exchange, and particularly relates to a novel corrugated plate type heat exchanger.
Background
In the modern energy industry, heat exchangers are one of the most frequently used devices that are indispensable and used in the process flow. Conventional heat exchangers mainly include shell-and-tube heat exchangers and plate heat exchangers. The shell-and-tube heat exchanger conducts heat through the tube walls of the tubes, so that heat exchange between two fluids inside and outside the tubes is realized, the heat exchange is limited to the shape of the tube bundle, and the heat exchange of the fluids at the center of the tube bundle is insufficient and uneven, so that the heat exchange efficiency is low. The plate heat exchanger conducts heat through the wall surface of the closely contacted guide plate, so that heat exchange of two fluids on two sides of the guide plate is realized, the guide plate is limited to be fixed through the connecting rod, the sealing performance is not strong, and leakage is easy.
SUMMERY OF THE UTILITY MODEL
The utility model aims to improve the heat exchange efficiency and the industrial production level, and provides a novel corrugated plate type heat exchanger.
In order to achieve the purpose, the utility model adopts the following technical scheme: a novel corrugated plate heat exchanger is characterized in that: the heat exchanger mainly comprises a shell, a guide plate and a fluid distributor, wherein the shell comprises a left end plate, a right end plate, a front baffle, a rear baffle, an upper cover plate and a lower cover plate. The guide plates are symmetrically stacked up and down and welded between the left end plate and the right end plate, the fluid distributor comprises a front fluid distributor and a rear fluid distributor, one end of the fluid distributor is connected with a flow channel formed by adjacent guide plates, and the other end of the fluid distributor is connected with a fluid inlet and a fluid outlet on the end plate.
According to the novel corrugated plate type heat exchanger, the guide plates are bent from flat plates to form corrugated cross sections, and the bulges of adjacent guide plates are tightly welded together to form a fluid channel.
The front fluid distributor and the rear fluid distributor have the same structure, are formed by connecting a plurality of seal heads with the same cross section as the flow channel section and with smooth transition contraction through round pipes.
According to the novel corrugated plate type heat exchanger, the front fluid distributor is welded with the flow channel at one end with the same cross section as the flow channel, one end of the circular tube is welded with the fluid inlet and outlet of the right end plate, and the rear fluid distributor and the front fluid distributor are connected in the same mode.
According to the novel corrugated plate type heat exchanger, the front baffle and the rear baffle are provided with the fluid inlets and the fluid outlets.
According to the novel corrugated plate type heat exchanger, every other row of flow channels formed by welding the guide plates are connected with the front fluid distributor and the rear fluid distributor in a welding mode to form inner flow channels, and the rest of flow channels form outer flow channels.
Compared with the prior art, the utility model has the following advantages:
according to the utility model, due to the different bending angles of the guide plates, the formed flow channels are diversified. Because the shape of the flow channel is similar to an ellipse, the heat exchange of fluid at the center of the flow channel can be promoted, the heat exchange is more uniform, and the heat exchange efficiency of the plate heat exchanger is improved.
The utility model has smooth flow channel and small fluid flow resistance, reduces the kinetic energy loss of the fluid and reduces the energy consumption of the system.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
As shown in the figure, the novel corrugated plate type heat exchanger is characterized in that hot fluid flows into the heat exchanger from a right end plate fluid inlet 11, then enters a front fluid distributor 12, is distributed to various flow channels connected with the front fluid distributor 12 through the front fluid distributor 12, then is collected through a rear fluid distributor 13, and finally flows out of the heat exchanger from a left end plate fluid outlet 14; cold fluid flows into the heat exchanger through a front baffle fluid inlet 21, then through an unsealed area 22 in the housing, and finally exits the heat exchanger through a rear baffle fluid outlet 23. The flow passage through which the hot fluid flows is also the inner flow passage, and the flow passage through which the cold fluid flows is also the outer flow passage. The hot fluid and the cold fluid exchange heat fully in the shell, so that the heat exchange is more uniform and efficient, and the flow channel is smooth, the flow resistance is small, and the power consumption is less.
As shown in the figure, the right end plate is provided with 2 fluid inlets, and correspondingly, 2 front fluid distributors, 2 rear fluid distributors and 4 guide plates are stacked and welded. The number of the above components is not limited by the above data.
The front fluid distributor 12 and the rear fluid distributor 13 have the same structure, the left end plate 3 and the right end plate 4 have the same structure, the front baffle 5 and the rear baffle 6 have the same structure, the upper cover plate 7 and the lower cover plate 8 have the same structure, and the adjacent guide plates are symmetrical.
The utility model has been described in connection with the accompanying drawings, it is to be understood that the utility model is not limited to the specific embodiments disclosed, but is intended to cover various modifications, adaptations or uses of the utility model, and all such modifications and variations are within the scope of the utility model.
