Embodiment Construction

[0016] The present invention will be further described below in conjunction with embodiment.

[0017] Such as image 3 and Figure 4 The anti-blocking device for the filter of the ultra-low temperature refrigerated storage tank shown in the figure uses a PTC heating element to heat the filter, so as to solve the problem of ice blockage and oil blockage safely, reliably and effectively. The filter anti-blocking device of the ultra-low temperature storage box includes a heat conductor 1 arranged outside the filter and closely attached to the outer surface of the filter 4. The heat conductor 1 is equipped with a PTC heating body 2, and the heater 2 is wrapped in the heat conductor 1. , the heat conductor 1 has a sub-arc structure. The heat conductor 1 is made of aluminum material and formed into an integral structure by one-time die-casting. The inner diameter of the heat conductor 1 is larger than the outer diameter of the filter 4 by any value between 0.01 mm and 0.5 mm. Th...

Abstract

The invention discloses an ultra-low-temperature freezing storage tank filter anti-blocking device, which comprises a heat conductor arranged on the outer part of a filter and arranging clinging to the outer surface of the filter. A PTC heating element is arranged in the heat conductor and is wrapped in the heat conductor; and the heat conductor is of an inferior arc-shaped structure. The heat conductor is of an integral structure formed by one-time die-casting of an aluminum material. The ultra-low-temperature freezing storage tank filter anti-blocking device provided by the invention has thebeneficial effects that a safe and controllable heating effect is achieved on the filter according to the characteristic of the PTC heating element.

Description

technical field [0001] The invention belongs to the technical field of low-temperature freezing storage boxes, and in particular relates to an anti-blocking device for ultra-low temperature freezing storage filters. Background technique [0002] The filter of the ultra-low temperature refrigerated storage box is mainly used to filter impurities and prevent ice blockage and oil blockage in the refrigeration system. The outer shell is formed with a copper tube, and the inlet and outlet are equipped with metal mesh, which can effectively filter impurities. Molecular sieve with excellent internal hygroscopic properties is used as a desiccant. When the refrigerant flows through, the contained moisture is absorbed by the molecular sieve, and the dirt is blocked by the filter to ensure the normal operation of the capillary tube and the refrigeration system. On the low-pressure side of the refrigeration system, due to the low temperature, water will cause ice blockage in the filter,...
