Description
Technical Field
The utility model relates to a quick medical treatment inspection field, in particular to control by temperature change storehouse that is used for dry-type fluorescence/colloidal gold reagent card to detect.
Background
The dry fluorescent/colloidal gold detection technology is a rapid medical inspection technology, and the device corresponding to the technical scheme comprises a dry fluorescent/colloidal gold reagent card, an optical measurement module and a reagent card moving assembly, wherein the reagent card is moved to a corresponding detection position of the optical measurement module through the moving assembly for scanning detection.
Before scanning and detecting the dry-type fluorescence/colloidal gold reagent card, the dry-type fluorescence/colloidal gold reagent card is firstly conveyed to the temperature control bin from the card feeding device, so that the dry-type fluorescence/colloidal gold reagent card reacts in an environment with relatively stable and controllable temperature.
In dry fluorescence/colloidal gold detection, a temperature environment which is relatively stable and meets the reaction requirements is required when an object to be detected and a detection reagent react, so that the repeatability and the accuracy of a detection result are ensured. However, the existing dry-type fluorescence/colloidal gold detecting instrument has no corresponding temperature control scheme for temperature control, or completely depends on a room temperature environment, or only can provide an auxiliary heating function, and when the environmental temperature exceeds the reaction temperature range, refrigeration cannot be performed to meet the reaction temperature requirement.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a temperature control bin for detecting a dry-type fluorescence/colloidal gold reagent card.
The purpose of the utility model is realized through the following technical scheme:

A first cooling fin is arranged on one side, close to the interior of the temperature control cabin body, of the Peltier paster in a clinging mode, and a first fan is arranged on the first cooling fin.
The first radiating fin comprises more than one strip-shaped fin, and the diameter of the first fan is not larger than the width of the first radiating fin. The contact area of the radiating fin and the air is increased through the strip-shaped fins. The area of the first heat sink and the first fan is relatively small, mainly because: 1. the internal space of the temperature control bin is small, and the amount of air needing heating/refrigerating is small; 2. peltier has a much higher heating efficiency than cooling efficiency, so that a strong heat radiation efficiency is not required when heating a small space. Meanwhile, the temperature control space is small, and particularly high cooling efficiency is not needed during refrigeration. 3. One of the reaction power sources of the reagent card is spontaneous chromatographic force (capillary action) of trace liquid, and under the strong air convection environment, the evaporation of the liquid is accelerated (especially, the trace liquid, the total liquid amount in one reagent card does not exceed 200 mu L), so that the chromatography is interrupted, and the reaction is stopped. Therefore, the air flow rate on the surface of the reagent card must be strictly controlled, and a fan with a small area can just meet the requirement in the aspect.
A second cooling fin is arranged on one side, close to the outer portion of the temperature control cabin body, of the Peltier paster in a clinging mode, and a second fan is arranged on the second cooling fin.
The second cooling fins are sunflower-shaped fins, and the diameter of the second fan is equal to that of the sunflower-shaped fins. The specific surface area of the sunflower-shaped fin radiating fin is larger than that of the strip-shaped fin, and the sunflower-shaped fin radiating fin has a larger air contact surface, so that the radiating effect is enhanced. The area of the second radiating fin and the second fan is relatively large, and the main reasons are as follows: 1. when refrigerating in the control by temperature change storehouse, the second fin end is the end that generates heat, and its power of generating heat is positive correlation with refrigerating power (inside temperature is lower promptly, and outside heat is more), consequently needs more efficient radiating efficiency, utilizes the air flow of higher speed simultaneously, blows off the heat on the fin to the external environment in rapidly. 2. The sunflower shape can make the hot air flow uniformly dispersed in the space, and the condition of local air overheating in the space can not be formed.
The Peltier is made of a semiconductor material or a metal material. Generally, the peltier effect of a metal material is weak, while a semiconductor material is much stronger, so that thermoelectric cooling devices for practical use are made of semiconductor materials.
The temperature control bin body is also provided with a bin door which can be opened and closed and is used for the dry-type fluorescence/colloidal gold reagent card to enter and exit the temperature control bin.
The working process of the utility model is as follows:
