Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange, and in particular relates to a heat exchange plate and a welded plate heat exchanger. Background Art

[0002] Heat exchanger technology is an engineering method for transferring heat between fluids. It is widely used in heating, cooling, evaporation, condensation and other processes. It exchanges heat between two different fluids to increase the temperature of one fluid and reduce the temperature of the other fluid to meet different process requirements. The basic principle of the heat exchanger is the heat transfer between fluids. When the two fluids flow through the two sides of the heat exchanger, the heat is transferred from the high-temperature side of the fluid to the low-temperature side of the fluid, thereby achieving temperature changes.

[0003] In the prior art, the manufacturing process of the welded plate heat exchanger is relatively complicated. This is because the surface of the heat exchange plate is designed with grooves of different shapes, which are specially engraved to improve the heat exchange efficiency. However, these designs increase the difficulty of welding in practical applications because the installation process of the heat exchange plate becomes more complicated. In addition, when the fluid flows into the heat exchanger, if there are impurities in the fluid, these impurities may block the channels on the heat exchange plate, thereby affecting the normal operation of the heat exchanger. Therefore, a heat exchange plate and a welded heat exchanger appear. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1

[0025] Reference Figure 1 , which is the first embodiment of the utility model, provides a heat exchange plate and a welded plate heat exchanger, including a frame mechanism 100 and an exchange mechanism 200. The frame mechanism 100 includes a support leg 101, and a fixing plate 102 is fixedly installed above the support leg 101.

[0026] Specifically, a fixing seat 105 is fixedly installed on the outer wall of the fixing plate 102 , a fixing screw 103 is fixedly connected to the right side of the fixing seat 105 , and a fixing nut 104 is sleeved on the outer wall of the fixing screw 103 .

[0027] When in use, after the frame mechanism 100 clamps the exchange mechanism 200, the fixing nut 104 is tightened to fix the exchange mechanism 200, and the hot fluid enters from the first inlet 106 and the cold fluid enters from the second inlet 108. After passing through the exchange mechanism 200, the hot fluid cools down and the cold fluid heats up, and is discharged from the first outlet 111 and the second outlet 112 respectively.

[0028] In summary, by clamping the frame mechanism 100 and tightening the fixing nut 104, the exchange mechanism 200 in the heat exchanger is stably fixed, which improves the heat exchange efficiency, saves space, and facilitates installation and maintenance. At the same time, the fluid flows smoothly, which has high practical value and economic benefits.

[0029] Example 2

[0030] Reference Figure 2 and Figure 3 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a supporting and fixing frame mechanism.

[0031] Specifically, a first diverter box 110 is provided in the middle of the fixed plate 102, a partition 203 is provided in the middle of the first diverter box 110, a first inlet 106 is fixedly installed on the outer wall of the first diverter box 110, a first filter screen 107 is provided in the middle of the first inlet 106, a second inlet 108 is provided on the right side of the first inlet 106, and a second filter screen 109 is provided inside the second inlet 108.

[0032] Furthermore, a second diverter box 113 is disposed in the middle of the fixed plate 102 , a first outlet 111 is fixedly mounted on an outer side wall of the second diverter box 113 , and a second outlet 112 is disposed on the right side of the first outlet 111 .

[0033] When in use, after the exchange mechanism 200 is placed into the frame mechanism 100 and the position of the diverter box is aligned, the fixing nut 104 is tightened to ensure that the fluid can be introduced into the inlet after the exchange mechanism 200 is fixed.

[0034] In summary, by tightening the fixing nut 104, the stability of the exchange mechanism 200 is ensured, thereby improving the heat exchange efficiency. At the same time, the accurate installation process is also conducive to the uniform flow of the fluid, reducing the resistance of the fluid during the exchange process and reducing energy consumption. In addition, during the installation and maintenance process, due to the fixation of the exchange mechanism 200, the operator can perform related operations more conveniently, thereby improving the safety and efficiency of the work.

[0035] Example 3

[0036] Reference Figure 4 and Figure 5 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an exchange mechanism for cold and heat exchange.

[0037] Specifically, the exchange mechanism 200 includes a connecting block 202, on the outer wall of which a heat exchange plate 204 is fixedly mounted. The heat exchange plate 204 is W-shaped, on the outer wall of which a slot 205 is opened, and on the outer wall of which an opening tenon 206 is fixedly mounted.

[0038] Furthermore, a partition plate 203 is provided on the left side of the heat exchange plate 204 . The partition plate 203 is fixedly mounted on the inner side walls of the first diversion box 110 and the second diversion box 113 . A connecting plate 201 is welded on the outer side wall of the heat exchange plate 204 .

[0039] When in use, when installing the heat exchange plate 204, align the open slot with the notch 205 to form two separate diamond channels. The partition 203 in the diversion box introduces the two fluids into different channels, and the walls of the heat exchange plate 204 contact to exchange heat energy.

[0040] In summary, the structural stability and heat exchange efficiency of the heat exchange plate 204 are ensured through a precise installation process. At the same time, the independent channel design helps to improve the uniformity of fluid flow and enhance the heat exchange effect. The W-shaped setting reduces the trouble in the manufacturing process. At the same time, multiple heat exchange plates 204 can be processed at the same time. The filter setting can remove impurities that may appear in the fluid, thereby reducing the possibility of channel blockage.
