Embodiment 1

[0044] The phase change material 1132 includes the following raw materials in parts by weight: 15 parts of gypsum, 15 parts of limestone powder, 12 parts of calcium hydroxide, 5 parts of calcium stearate, 18 parts of acetic acid, 16 parts of borax, 10 parts of bentonite, and 8 parts of potassium chloride , 10 parts of yttrium oxide.

Embodiment 2

[0046] The phase change material 1132 includes the following raw materials in parts by weight: 20 parts of gypsum, 10 parts of limestone powder, 6 parts of calcium hydroxide, 8 parts of calcium stearate, 12 parts of acetic acid, 10 parts of borax, 8 parts of bentonite, and 15 parts of potassium chloride , 15 parts of yttrium oxide.

Embodiment 3

[0048] The phase change material 1132 includes the following raw materials in parts by weight: 18 parts of gypsum, 12 parts of limestone powder, 9 parts of calcium hydroxide, 7 parts of calcium stearate, 15 parts of acetic acid, 13 parts of borax, 8 parts of bentonite, and 12 parts of potassium chloride , 12 parts of yttrium oxide.

[0049] The phase-change material 1132 is composed of the above-mentioned raw materials. The material is non-corrosive, and the packaging and the metal tube 1131 are not prone to leakage and pollution. At the same time, the phase-change latent heat is high, the thermal conductivity is high, and the phase-change temperature is appropriate. 1, the temperature inside is adjusted without external energy and action mechanism, which further improves the safety of the conversion cabinet.

Abstract

A multifunctional signal conversion cabinet is characterized by comprising a cabinet body, a shell and a heat dissipation and dehumidification system. A plurality of partition plates are detachably arranged in the cabinet body from top to bottom and divide the cabinet body into a plurality of cavities from top to bottom, and heat dissipation holes are formed in the partition plates. The shell sleeves the outer side of the cabinet body, an airflow channel is formed between the inner wall of the shell and the outer wall of the cabinet body, and a plurality of air inlets communicated with the airflow channel are formed in the shell. The heat dissipation and dehumidification system comprises a fan arranged in the airflow channel, an air guide disc arranged in the bottom cavity of the cabinet body, a ventilation window arranged on the cabinet body and opposite to the bottom cavity of the cabinet body, and an air outlet formed in the top of the cabinet body and communicated with the airflowchannel. The draught fan works to drive air in the air flow channel to flow to form air flow, the air flow enters the cabinet body through the ventilation window, flows from bottom to top under the effect of the air guide disc and flows into the air flow channel again through the air outlet, when the air flow flows in the cabinet body, the temperature and the humidity in the cabinet body can be reduced, and the good heat dissipation effect and the good dehumidification effect are achieved.

Description

technical field [0001] The invention belongs to the technical field of electrical control equipment, in particular to a multifunctional signal conversion cabinet. Background technique [0002] The signal conversion cabinet is to assemble signal conversion equipment, measuring instruments, protective electrical equipment and auxiliary equipment in a closed or semi-closed metal cabinet according to the requirements of electrical wiring. Safe control cabinet for equipment. [0003] In the prior art, for example, the Chinese patent application number 201720773518.8 discloses an anti-static power distribution cabinet, which includes a cabinet body, which includes a fixed bracket, and the fixed bracket is divided into three layers. There are arc-shaped protrusions, buffer pads are arranged on the arc-shaped protrusions, a master switch is arranged on the middle fixed bracket, a number of closing coils are arranged on the lower fixed bracket, and a current detector is connected to...
