Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1-3, the utility model provides a technical scheme: the utility model provides a plate heat exchanger with mechanical adjusting device, includes two sets of fixed plate 1, hot-medium pipe 2, cold medium pipe 3 and multiunit heat-conducting plate 4, adjusting part, and is two sets of 5 fixed connection of connecting rod are passed through to the inboard of fixed plate 1, hot-medium pipe 2 sets up the center department at fixed plate 1, cold-medium pipe 3 is provided with four groups, four groups cold-medium pipe 3 set up respectively in the four corners department of fixed plate 1, the multiunit the inboard at two sets of fixed plate 1 is installed to heat-conducting plate 4, heat-conducting plate 4 establishes the outside at hot-medium pipe 2, cold-medium pipe 3 through seting up the through-hole cover, adjusting part sets up the inboard at two sets of fixed plate 1.

In the present embodiment, the heat medium pipe 2 is disposed at the center of the heat transfer plate 4, and the four sets of the cold medium pipes 3 are disposed at the four corners of the heat transfer plate 4, respectively, which causes the center temperature of the heat transfer plate 4 to be high at the four corners when the heat medium is transferred in the heat medium pipe 2, and the cold medium pipe 3 transfers the cold medium, that is, heat exchange is performed at the junction of the cold medium pipe 3 and the heat transfer plate 4.

The adjusting part includes solid fixed splint 6, activity splint 7, dwang 8 and compression spring 9, solid fixed splint 6, activity splint 7 all overlap and establish in the outside of connecting rod 5, gu fixed splint 6 with 5 fixed connection of connecting rod, dwang 8 sets up in middle part one side of fixed plate 1, just dwang 8 passes activity splint 7, heat-conducting plate 4, solid fixed splint 6 in proper order, compression spring 9 is provided with multiunit, multiunit compression spring 9 sets up respectively between adjacent two sets of heat-conducting plates 4.

In this embodiment, through rotatory dwang 8, make movable clamp plate position on connecting rod 5 change, thereby the distance between fixed clamp plate 6 and the movable clamp plate 7 has been changed, because all be provided with compression spring 9 between heat-conducting plate 4, and then when movable clamp plate 7's position changes, compression spring 9 shrink or resume initial state and all can cause heat-conducting plate 4's removal, make the distance between two sets of adjacent heat-conducting plates 4 change, the area of contact between heat-conducting plate 4 and the air has been changed, thereby holistic radiating effect has been improved.

The inner sides of the fixed clamping plate 6 and the movable clamping plate 7 are abutted against the side wall of the heat-conducting plate 4 through a stop block.

It can be understood that the fixed clamping plate 6 and the movable clamping plate 7 are abutted against the side wall of the heat conducting plate 4 through the stop block, so that the distance between the heat conducting plate 4 and the fixed clamping plate 6 or the movable clamping plate 7 is ensured, the circulation of air is facilitated, and the heat dissipation effect is ensured.

The middle part and the upper and lower ends of the heat conducting plate 4 are respectively connected with the heat medium conduit 2 and the cold medium conduit 3 through arranging sleeves (not shown in the figure).

It can be understood that the middle part of the heat conducting plate 4 is provided with a sleeve connected with the heat medium conduit 2, so that the contact surface between the heat conducting plate 4 and the heat medium conduit 2 is increased, thereby prolonging the heat transfer time, and the heat conducting plate 4 and the cold medium conduit 3 are connected through the sleeve, thereby effectively prolonging the time of the heat exchange process and improving the heat exchange efficiency.

Dwang 8 all is connected through the bearing with two sets of fixed plates 1, activity splint 7, dwang 8 with solid fixed splint 6 passes through threaded connection.

The length of the sleeve is greater than when the compression spring 9 is fully compressed.

In the present embodiment, when the length of the sleeve is set to be less than or equal to the length of the compression spring 9 when it is completely compressed, and when the distance between the heat conductive plates 4 is adjusted, the movable clamp plate is gradually moved to the right side until the compression spring is in a completely compressed state by the rotation of the rotating lever because the moving distance of the movable clamp plate 7 is unclear, fatigue of the compression spring is easily caused under a continuous high-temperature environment, and the service life is affected.

The working principle is that the heat-conducting plate 4 is in contact with the heat-conducting medium conduit 2 and the cold-conducting medium conduit 3, namely heat transfer occurs at the joint of the heat-conducting plate 4 and the heat-conducting medium conduit 2, heat is transferred to the periphery at the center of the heat-conducting plate 4, and heat exchange occurs between four corners of the heat-conducting plate 4 and the cold-conducting medium conduit 3, so that the heat is transferred to the cold medium, in the using process, the position of the movable clamping plate 7 on the connecting rod is adjusted left and right by rotating the rotating rod 8, when the movable clamping plate 7 moves to the left, the distance between the adjacent heat-conducting plates 4 is gradually increased, so that the contact area between the heat-conducting plate 4 and the air is increased, and the heat dissipation effect is effectively enhanced; when the movable clamping plate 7 moves towards the right side, the distance between the adjacent heat conduction plates 4 becomes smaller, so that the temperature between the heat conduction plates 4 becomes higher, and the heat exchange efficiency is effectively improved under the condition that the chilling medium and the heat medium are not changed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
