[0018] The technical solution of the utility model is described in detail below in conjunction with specific implementation methods and the accompanying drawings of the specification.

[0019] like Figure 1-4 As shown, the compact gas-plate heat exchanger of the utility model can withstand a pressure of more than 0.1 MPa, and involves the following components: a first fluid outlet 1, a first fluid inlet 2, a second fluid inlet 3, a second fluid outlet 4, a heat exchange assembly 5, a heat exchange plate 51, a first fin 52, a second fin 53, and a sealing plate 6. Specifically, the heat exchange assembly 5 includes a heat exchange plate 51, a first fin 52, and a second fin 53. A plurality of heat exchange plates 51 are arranged at intervals, and a fin is arranged between two adjacent heat exchange plates 51 to form a fluid channel. The fin is placed between the plates along the gas flow direction to increase the heat transfer area on the gas side. The fin can increase the disturbance of the gas, which is beneficial to heat transfer. The first fluid inlet 2 and the first fluid outlet 1 are arranged on the left and right sides of the heat exchange assembly 5, and the first fluid inlet 2 and the first fluid outlet 1 are respectively connected to the transverse fluid channel. The second fluid inlet 3 and the second fluid outlet 4 are arranged at the upper and lower ends of the heat exchange assembly 5, and the second fluid inlet 3 and the second fluid outlet 4 are respectively connected to the longitudinal fluid channel. Sealing plates 6 are provided on the left and right sides of the heat exchange component 5 .

[0020] like Figure 2-4As shown, according to the different flow directions of the fluid, the fins between the heat exchange plates 51 are divided into the first fin 52 and the second fin 53. The first fin 52 is used to provide a longitudinal fluid channel for the fluid, and the second fin 53 is used to provide a transverse fluid channel for the fluid. In this embodiment, a first fin 52 is arranged on the plane of each heat exchange plate 51, and a heat exchange plate 51 is arranged on the other side of the first fin 52, and a second fin 53 is arranged on the other side of the heat exchange plate 51, and the cycle is cyclically arranged, and the heat exchange plate 51 is arranged on the outermost side. The first fin 52 and the second fin 53 are formed by pressing a flat plate, and their thickness and folding form can be adjusted according to specific needs. The existence of the fin can serve as a support for the plate, so that the heat exchanger can withstand higher pressure; the fin serves as an extended area of ​​the plate, and the existence of the fin can increase the disturbance of the fluid, increase the Reynolds number of the fluid, destroy the fluid boundary, and change the gas from laminar flow to turbulent flow. The thickness of the first fin 52 and the second fin 53 is greater than or equal to 0.1 mm. The first fin 52 and the second fin 53 are formed by pressing with a mold, and the fins can be pressed into different shapes according to different needs to meet different process requirements. The heat exchange plate 51 is a flat plate, and its thickness can be less than 0.4 mm.

[0021] In this solution, fluid 1 enters the transverse fluid channel from the first fluid inlet 2 and exits the heat exchanger from the first fluid outlet 1; fluid 2 enters the longitudinal fluid channel from the second fluid inlet 3 and exits the heat exchanger from the second fluid outlet 4. Fluid 1 and fluid 2 flow in their respective channels and exchange heat through the heat exchange plate 51; the first fin 52 is used to increase the heat transfer area of ​​fluid 1, and the second fin 53 is used to increase the heat transfer area of ​​fluid 2. In addition, the first fin 52 and the second fin 53 can increase the overall strength of the heat exchange component, so that the heat exchanger can withstand higher pressure.

[0022] Working principle:

[0023] Fluid 1 enters the heat exchanger from the first fluid inlet 2, and fluid 2 enters the heat exchanger from the second fluid inlet 3. Fluid 1 and fluid 2 enter their respective channels, which are provided with fins. Fluid 1 and fluid 2 exchange heat through a heat exchange component 5. The gases on both sides increase the heat transfer area through their respective fins. After heat exchange, fluid 1 exits the heat exchanger from the first fluid outlet 1, and fluid 2 exits the heat exchanger from the second fluid outlet 4, thereby completing heat exchange between the two gases.
