Description

Technical Field

[0001] The utility model relates to the relevant field of double evaporators, and in particular to a temperature control device for double evaporators. Background Art

[0002] In the field of modern refrigeration and temperature control technology, the dual evaporator system is gradually being widely used in many industries as an efficient and flexible temperature control solution. The dual evaporator system is configured with two independent evaporators, which can accurately control the temperature of different spaces or areas simultaneously or separately, thus meeting complex and changing temperature control needs.

[0003] The prior art with patent publication (announcement) number CN216217913U discloses a temperature control device for an evaporator, including a front shell of a thermostat, a fixed head, a containing frame, a partition plate, a connecting wire, a support rod, a clamping block, a connecting rod and a rear shell connecting block, wherein a containing groove is provided on the front surface of the front shell of the thermostat, a containing frame is fixedly connected to the lower surface of the front shell of the thermostat, a support rod is rotatably connected to the interior of the containing frame, a connecting wire is fixedly connected to the lower surface of the front shell of the thermostat by bolts, and a partition plate is snap-connected to the interior of the containing frame.

[0004] The above patent document discloses a temperature control device for an evaporator, which can solve the problems of poor fixing effect of the connecting wire of the existing temperature control device and inconvenience in disassembly and installation of the temperature control device, but has the following disadvantages:

[0005] When the above device is in use, the support rod and the clamping block use the first return spring to tighten the connecting wire. However, the spring may experience elastic fatigue after long-term use, resulting in a decrease in the tensioning force, affecting the fixing effect of the connecting wire. The "inlaid connection" between the clamping block and the connecting wire may cause the connecting wire to loosen or fall off due to vibration or external force.

[0006] In addition, during the operation of the temperature control device, the internal electronic components will continue to generate heat. If the heat cannot be dissipated in time, the internal temperature of the device will increase, thereby affecting the performance and life of the electronic components and may even cause failures, reducing the overall stability and reliability of the temperature control device.

[0007] Therefore, we make improvements on this and propose a temperature control device with double evaporators. Utility Model Content
